Never can remember how to submit patches instead of pull requests on here, ok, here goes nothin...

I am using ramps v1.2 on a mendel prusa, using the latest commit of sprinter (but It happened on earlier commits too). I run repsnapper, but he problem also occurs in pronterface. I have not tried running from sd card, because I don't have that option. I am running ubuntu, my skeinforge version 41.

I am having this issue, where my bot pauses (x and y stops moving) during a retraction/pushback. It can be viewed in this video:

http://www.flickr.com/photos/58101887@N02/5867736863/in/photostream

Sorry about the poor video quality, I didn't have my good camera with me today.

When I turn retraction to 1 mm, the pauses are quicker. And if I set retraction mm to 0 the pauses go away completely, but of course this causes ooze. Noone I talk to in #reprap or #makergearv2 has an answer to the problem, or has even seen it.

Indeed if I choose to comment acceleration in configuration.h when I try to compile I get an error because the variable decelerating use at the line 1179 in the file Srinter.pde doesn't not exist

Is there a enter missing from this line?
https://github.com/kliment/Sprinter/blob/master/Sprinter/pins.h#L439

Expected: if the thermistor is physically removed from the hotend (due to an accident) while printing, Sprinter should be able to recognize that even though power is being applied the temperature readings are not acting as they should because there's been a hardware failure. In other words, Sprinter has no way of avoiding or detecting this fatal scenario. Once this event occurs it is likely the hotend will be destroyed by overheating, or worse could occur to the user.

Actual: Sprinter will let you burn your hotend off the carriage, and if you're really neglectful it could become a fire hazard to you, your family, and/or possessions.

Please fix this.

has a change in slope at 205°. Not sure how to fix that, we have the same trouble in marlin...

If using AD595, I had to change two lines to get some serial temperature reading. Apart from that, the temperature conversion routines seemed to work well.

case 105: // M105

•    #if (TEMP_0_PIN > -1) || defined (HEATER_USES_MAX6675)
  

•    #if (TEMP_0_PIN > -1) || defined (HEATER_USES_MAX6675) || defined (HEATER_USES_AD595)
   tt = analog2temp(current_raw);
   #endif
   #if TEMP_1_PIN > -1
     bt = analog2tempBed(current_bed_raw);
   #endif
  

•    #if (TEMP_0_PIN > -1) || defined (HEATER_USES_MAX6675)
  

•    #if (TEMP_0_PIN > -1) || defined (HEATER_USES_MAX6675) || defined (HEATER_USES_AD595)
       Serial.print("ok T:");
       Serial.print(tt); 
     #if TEMP_1_PIN > -1
  

Hi,
Found some problem in the M190 code as the analog temperature needed is compared with the actual analog temperature BUT using temp2analogh function instead of temp2analogBed function.
This causes, if you have different temperature tables to compare carrots with cabbages (French saying).

I guess the code in Sprinter.pde

  case 190: // M190 - Wait bed for heater to reach target.
  #if TEMP_1_PIN > -1
    if (code_seen('S')) target_bed_raw = temp2analogh(code_value());
    codenum = millis(); 

Should be:

  case 190: // M190 - Wait bed for heater to reach target.
  #if TEMP_1_PIN > -1
    if (code_seen('S')) target_bed_raw = temp2analogBed(code_value());
    codenum = millis(); 

Best regards, and thanks for this great piece of code.

I experienced some weird/random ultrafast moves during print. It looks like it would skip steps but does not.
Is this normal behaviour because I have the delays enabled?

make a min startup speed like 50 % if last value is 0.
Maybe for 10 sec

During a recent print, I paused because I could see there was a plastic problem, so I homed in X and Y.... of course, the nozzle sitting there oozed etc, so I primed the extruder....

when I resumed, the extruder RETRACTED the amount of extrusion I had extruded to prime. In other words, when I manually extruded 150mm of extrudate during pause, I subsequently incremented the E position.

After resume, the next E command is now 150mm back, so it retracts 150mm.

On Pause it would be nice if Pronterface took note of the next XYZE position (in the last command, and moved to Z, then X/Y, then G92'd the E to the last command's value.

I say Z first, because obviously you don't want the print head going THROUGH anything that's on the table, and well.. the E is obvious I think.

What do you think??

Use the MAX_PWM_POWER value for Autotune

Hey kliment,

In the most recent commit when I try to compile or upload I get an error message. Previous versions have worked just fine. \

Here's a shot of the Arduino IDE: http://www.flickr.com/photos/ccotter247/6223423055/in/photostream

I just love the Makefile included with Sprinter.. no more crappy Java IDE for me! 👯

I ran into a problem though, where I first tried to build against Arduino 1.0.2 which didn't work. on closer inspection I saw that the Makefile was only tested against Arduino 0022. so I did a 'make clean' and tried again against 0022, but it still didn't work.. after scratching my head for a while, I found out that applet/Sprinter.cpp was not removed on 'make clean'.

define Y_MIN_PIN 20 in pins.h

is same PB0_SS_PCINT0 in Teensy2.0++ (A90USB1286)

I think the PB0_SS_PCINT0 port is crashed intenally.

I found this pin has over current arround 80mA When this pin make to Ground .
So A90USB1286 was over heated.

Hi,

Here's a little patch to build Sprinter with arduino 1.0. I don't now if it's clean but it work's ;-)

Ignore extruder feedrate limit for reverse moves, and also the first forward move after a reverse

I am having a lot of issues using external stepper drivers that require at least a 2μs pulse on the step pin. In addition, my movements are controlled by worm gears so there is a large amount of friction. Is there a #define in the configuration.h file I am missing. Will I have to modify the interrupt functions? Any help would be greatly appreciated. I can post my findings on my project website as well.

If i choose temp table 7 in either one or both #define THERMISTORHEATER and #define THERMISTORBED it messes up the temp readings.

Sometimes it reads 5C even w/o any thermistor connected and sometimes it jams up the temp readings completely by freezing after a few seconds.

(tested on SL 1.3a)

and.. it semes not to be the table it self... because .. when I paste the(content of temp table 7) table under the "#if (THERMISTORHEATER == 1) || (THERMISTORBED == 1)" it works great.

I would like to use the content of file fastio.h for teaching, but I do not like to teach methods that are only usable in GPL licensed code. Are you still in contact with the original author Triffid_Hunter and could you allow me to redistribute the file fastio.h (and only that one file) under the Apache-2.0 license? The Apache-2.0 license would allow reuse of that code in closed-source software but still requires attribution in all forms of distribution (binary or source code) . I know that this topic is highly debatend amongst the free/open source community, so thanks for your consideration.

Hello to All

I use a Sanguinololu 1.3a and the homig of the Y axis is not working are there any settigs within Sprinter I can try?
As far as I can check the hardwear and the elektronik is working correct, but I have to say that I am not very good in elektronics.
I canged the axis from X to Y (electronic) and hade the same effect at the Y(hardwear) axis (Mendel).
Dose any one have Idears to solve this problem.

Kinde regards
Peter

Ps.: Sprinter is great I can understand the basic funktions and it`s reacting as described :-)

To correctly calculate it, the move distance in the XYZ space must be computed first.
Divide it by feedrate/60 and you get the time_to_move in seconds.
For each axis, divide axis move distance by the calculated time_to_move to get their actual feedrate and check it doesn't violate max speed constraints in configuration.h.
If any axis does violate them, scale other axes' feedrates accordingly, to calculate the right interval for each one (scale other axes speed may not be needed when 4D bresenham gets in, but it's necessary now)

By trial and error I found that if I turn max_travel_acceleration_units_per_sq_second[] for Y down 1 unit to 499, it exhibits this behavior http://www.youtube.com/watch?v=HyN_tl6iSug
No acceleration and slow travel jumping to full speed after a while.
I can't figure it out.

A variable depending on definition of RAMP_ACCELERATION or EXP_ACCELERATION is used without checking if it's actually defined. This is also not correct, since min_units_per_second is actually the start speed of an accelerated move, not the best speed one can use to home the axis.
In G28: feedrate = min_units_per_second * 60;
The same for y.

In pins.h

The following to pins "TEMP_2_PIN+55, TEMP_BED_PIN+55" have been added to sensitive_pins.

TEMP_2_PIN is only defined if you have board type 33
TEMP_BED_PIN is not defined anywhere

result. it wont compile like this.

The pin numberings in fastio.h are inconsistent with the pin numberings used in Teensyduino, which is used to compile for Teensylu/Printrboard. This causes unexpected behavior when fastio and Arduino pinMode/digitalWrite/etc are intermixed, because different pins are accessed. Note: Teensyduino does not support pins PE2/PE3, so fastio MUST be used to access those 2 pins. Below are the necessary modifications to fastio.h for the Teensyduino compatibility, and to pins.h for the affected boards (Teensylu & Printrboard)

Hi,
I'm not sure if this is something I'm doing wrong or something in either the firmware or printrun or maybe skeinforge.
(I don't know which firmware version I have! It was the one dished out at the Bath masterclass.)

Anyway, to reproduce my problem, print something (probably without any filament loaded & heat off).
Let it do a layer or so, then click the "pause" button in printrun.
Optional : Hit Reset in printrun
Then either "restart" if you didn't reset or start a new "print" if you did.

The extruder then tries to suck back everything it just printed. This generally doesn't work and you now need to refeed your filament to start printing again. As well as cancel the print that just started with the filament end hanging loose.
I spent a long time thinking I was doing something wrong in Skeinforge before eventually not changing anything and loading the same gcode and printing again and it noticing that it didn't do what it did when I first loaded the file.
(This makes me think it's nothing to do with Skeinforge settings)

This is a bit annoying when you're trying to tune settings and every time you want to restart a print you need to completely power down the printer (remove USB and main power) or hit the reset switch on the control board.

It sort of makes sense to do this, I'm using "absolute" setting in "dimension". So I suppose that taking the extruder back to zero makes sense. But I would have thought the "Reset" in printrun could reset the extrude distance to zero...

Thanks,

When using the experimental branch and the lift setting is activated in Slic3r, during the lifts, Sprinter will lower the head more and more until it crashed into the bed (over the course of several lifts). When this happens, the Z endstop is triggered, but ignored.

The master branch is unaffected.

Hi,

I had an attempt to update sprinter for Gen7 electronics, which seems to be working fine as far as I am concerned..
I have documented the changes that I have made here:
http://forums.reprap.org/read.php?147,119166

but since I am no programmer and I don't know anything about updating code in github, I guess someone might incorporate the updates so more ppl can make use if it..

** I guess I shouldn't write this as an issue, but I didn't know where else to go..

Thanks

• When endstop is hit, stop making steps but count how many "virtual steps" are made. Then when moving in the opposite direction decrement the counter and start stepping when it hits zero.
• And when next recalculating update the current position with the virtual steps

Kliments idea
if(!endstop)step;else(++counter);
if(counter)counter--; else step;

The comment_mode does not work:
Trying to send a comment line starting with ";" does block the communication completely and subsequent commands are ignored. Only a reset can re-activate the controller.
And a comment following a command in the same line is not interpreted; the whole line is currently ignored.

Firmware: kliment-Sprinter-52f7f30 Ver1.3.11T
Software: PronterFace(Sorry, I don't know the version)
Hardware: Sanguinololu V1.3a
MCU: Mega644P
printer: Mendel
Sprinter configuration: Size= 170_160_100;

Operation steps:
1 Load a file(*.stl or *.gcode)
2 press All-Home button
3 press print button
~~~~~~~~~~~~~ the printer start print, but X and Y-axis did not move to center fist.
5 press pause button
6 move Y+ 100mm,
~~~~~~~~~~~~~ the bed will move for a small distance, about 80mm from home, then Stop.looks like reach the Y-end.

Another operation steps:
1 load a file
2 press All+home button
3 press Y-home button
4 press print button
~~~~~~~~~~~~~~~~ as same as previous operation, Y is wrong position.
5 press pause button
6 press Y-Home button, so X-home button
7 Press Restart button
~~~~~~~~~~~~~~~~~ printer looks work good.

Is this a bug? or somewhere in configuration.h can correct this problem?
what will happen on RAMS?

Hello,

I have a extra board from makerbot replicator 2. It is possible to flash sprinter firmware on it?

Thank you

Arduino's Millis() has an overflow after 9h32min. If you print something really long, or the machine was left powered before starting a print, this could be problematic.

see e.g. http://www.faludi.com/2007/12/18/arduino-millis-rollover-handling/

Alternatively, there seems to be a possibility to reset the internal millis() counter :
timer0_overflow_count=0 before a linear move might also do trick.

If you send the command to change head bed, hot end, or fan speed, they are executed much longer before they should.

I had this happening to me where the hotend was turned off minutes before the print was finished, resulting in the hot end being too cold to extrude before the print was finished.

Same thing is happening on first layer where the fan is turned on before the first layer is finished, resulting in, where the fan is on, being unable to stick to the bed.

My buffer is also set to 32 steps to prevent it from running out, so the commands are executed a lot before than what they should.

If your temp sensor ever comes unplugged, the temp reading registers as 0. This will cause the heater to run full out, causing a nasty meldown of plastic...

It would be nice if a missing temp sensor disabled the heater (bed and nozzle(s)).
Thanks!

I downloaded and compiled this version using 023 and my configuration.h out of the 52f7f30 build (could not find any differences).

Using Pronterface (d731aaf) I can move the Z axis, but when I hit the Z-home button it does not attempt to go home. Reverting to 52f7f30 build fixes it.

Changed filment this moring to a diffrent colour, need to re-callabrate the extruder.

PLA brown, it melted at 195C so no problem, Had my steps_mm set at 733, maked off the 110 and it only pushed 35 mm down the tube. In the end I stopped at 3000 steps_mm and decided to re-flash back to an earlier version and the problem was fixed.

I was running the latest Sprinter, version downloaded 16/5/2011
Not 100% sure what the problem is.
Hardware, Prusa wih RAMPS 1.2 with SDRamps

The PIN_PS_ON should be enabled when a stepper/heater is enabled, and disabled a certain waiting time after the last use of the steppers/heaters.

the reprap wiki has M203 as

M203: Record Z adjustment
Example: M203 Z-0.75
This records a Z offset in non-volatile memory in RepRap's microcontroller where it remains active until next set, even when the power is turned off and on again. If the first layer is too close to the bed, you need to effectively move the bed down, so the Z value will be negative. If the nozzle is too far from the bed during the first layer, the Z value should be positive to raise the bed. The maximum adjustment is +/-1.27mm.

Sprinter Experimental it's:
M203 Temperature monitor for Repetier

Sprinter Main does not have 203 implemented.

What do other firmwares have M203 as? is reprap wiki page wrong?

Trying to set up RepRap to use new hotend with a different thermistor, firmware uploads OK but depending on the value of THERMISTORHEATER Pronterface either connects fine or fails to connect. With value of 1-4 the printer can be connected to fine, a value of 5-7 causes Pronterface to get stuck on "Connecting..." I have been able to reproduce this consistently. I can make it connect with THERMISTORHEATER = 5 if I also set THERMISTORBED to 5. I am using commit de2feb0 with the following changes

I realised that my printer was printing mirrored and so I reversed direction for the X motor (const bool INVERT_X_DIR = true;), of course the X end stop is then at the wrong end. Rather than move the end stop I tried setting X_HOME_DIR to 1 instead of -1 but the X motor then doesn't move when the home button is pressed (it does move if the X+ and X- buttons are pressed), I tried playing with max_software_endstops but it made no difference. I got around the problem by moving the endstop to the X motor end but the weight distribution means that the X-Idler end doesn't always drop as it should. I can add weights or springs but it worked a lot better when I homed to the x-idler end.

I had some trouble with prints failing because the temperature was dropping. I guess it is caused by a bad temperature reading, triggering this code in Sprinter.pde:
#ifdef MINTEMP
if(current_raw <= minttemp)
target_raw=0;
#endif

If instead of setting the target_raw to 0 the heater_pin can be set low, so if the next reading of the temperature sensor is ok the printer keeps on managing the heater.

I changed Sprinter.pde by moving #ifdef MINTEMP to where the heater pin is managed:

if (TEMP_0_PIN > -1) || defined (HEATER_USES_MAX6675) || defined (HEATER_USES_AD595)

#ifdef PIDTEMP
  error = target_raw - current_raw;
  pTerm = (PID_PGAIN * error) / 100;
  temp_iState += error;
  temp_iState = constrain(temp_iState, temp_iState_min, temp_iState_max);
  iTerm = (PID_IGAIN * temp_iState) / 100;
  dTerm = (PID_DGAIN * (current_raw - temp_dState)) / 100;
  temp_dState = current_raw;
  analogWrite(HEATER_0_PIN, constrain(pTerm + iTerm - dTerm, 0, PID_MAX));
#else
  if(current_raw >= target_raw)
  {
    WRITE(HEATER_0_PIN,LOW);
    #if LED_PIN>-1
        WRITE(LED_PIN,LOW);
    #endif
  }
  else 
  {
    WRITE(HEATER_0_PIN,HIGH);
    #if LED_PIN > -1
        WRITE(LED_PIN,HIGH);
    #endif
  }

Getting compile error when I comment out RAPID_OSCILLATION_REDUCTION

Hey,

I just updated from a version of Sprinter (Tonokip) around mid May and found that the Repsnapper "Current Temp" box was being left empty. I don't have a heated bed, and the feedback from M105 is correctly showing the temp.

I thought at first it was a formatting issue, but turns out it's not.

In the earlier version of the firmware, the output code was:

      Serial.print("T:");
      Serial.println(tt); 

and if I add those two lines in before the current code... like so:

      Serial.print("T:");
      Serial.println(tt); 
    #if (TEMP_0_PIN > -1) || defined (HEATER_USES_MAX6675) || defined HEATER_USES_AD595
        Serial.print("ok T:");
        Serial.print(float(tt));
      #if TEMP_1_PIN > -1 || defined BED_USES_AD595 
        Serial.print(" B:");
        Serial.println(float(bt));
      #else
        Serial.println("");
      #endif
    #else

then everything goes back to working... I think repsnapper misses the T: because of the "ok"

With current master d651a6c filament retraction does not work after some movements. I sliced a file using skeinforge and at some points retraction by 5mm causes the motor to make an approx 800Hz sound. The motor does not move / retract the filament at all but makes some loud noise. Pushing the filament forwards afterwards results in a big blob in the printed part.

Most of the time retraction works well; but some GCode-combination causes the Extruder to stop retracting.

One of those cases is in the following GCode-Snippet:

G90
G92 X77.1 Y98.7 Z0.36 E30.6 ;start from here
; this was line 420
;G1 X75.894 Y97.349 Z0.36 F1440.0 E30.616

G1 F798.0
G1 E25.697 ; motor does not move, approx 800Hz sound (losing steps?!)

In Configuration.h I have (manually retracting the extruder at 2700mm/min does work)

#define _MAX_FEEDRATE {400, 400, 2, 45}       // (mm/sec)    

The experimental branch shows the same behaviour.
6d5a329 was working alright.
Any ideas what could cause such a behaviour?
