smoothieboard's Introduction

Smoothieboard

Smoothieboard is a free, open source, high performance and modular G-code interpreter and CNC controller for the LPC17xx micro-controller (32-bit ARM Cortex-M3).

smoothieboard's Issues

Add dimensions?

Nice to see a printable template for the board - would it be possible to put the dimensions and mount points in x,y format on the pdf?

2x3 connectors for ribbon cables ( SPI port ).

Hi !

I bought a bunch of these : http://www.ebay.com/itm/330833147832?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
They work great for the 5th-stepper connector, but a few caps and resistors are in the way for the SPI port. Could we move them away a bit ? ( that's on the beta board I have, may be different on the current eagle files ).
The connectors are 15*9mm.

Thanks !

Menu typesetting messed up issue

hi,
We use st7565_glcd for menu display, and the resolution is 128*64.After tedious configuration , finally it works, but the menu typesetting is a big issue as the following:

As we can see the first row is right typesetting when it is intialized, but it will change from time to time, switch back and force from 3 rows.

Does anyone encounter the same issue? Any suggestion are welcome!

Regards!
Cheng

missing images in documentation

Hello,
I'm trying to follow the documentation on install smoothie on a k40 bluebox, but the images are not present in the both page
http://smoothieware.org/blue-box-guide
and
http://smoothieware.org/bluebox-guide

I remember there were usefull info on the type of alimentation of the laser and how to connect it

Add 5V pins to stepper logic breakouts

Add 5V pins to stepper logic breakouts to better support external stepper drivers.

version updates missing

eagle files still say v1.0 in the bottom right on schematic page - see page 3 of pdf and eagle sch. Also may I suggest v1.1 be added to all pages. I was looking for D7/D8 on my v1.0b board until I realised there was a misprint within eagle and I was referring to the wrong schematic

Schematic file

The .sch file is damaged. I want a .sch schema file.

Next rev: room for friction locks on header connectors

In the next revision, please position the 0.1" header connectors and surrounding components to allow use of friction lock style connectors. An example 4-pin P/N is Molex 22-16-2041.
Planning to use my Smoothieboard in a CNC mill and I expect vibration; I would appreciate the assurance that connectors will not work loose over time that is provided by locking ramps.

Principle library File

I can't open the .sch file. I want the library file for the schematic. I want to draw this schematic from scratch.

R78 is too small

This is just a suggestion for a minor improvement to smoothieboard. I recently hooked up my smoothieboard to a 24V power supply and noticed immediately that the red VBB led was so bright I could hardly see the nearby green led's 1-4

R78 is too small in comparison to the other current limiting resistors. This is the current limiting resistor on the VBB LED10. It's 2.2Kohms, but even at 12V the LED is extremely bright in comparison to the other LEDs, and at 24V it's extremely bright. The 2.2K resistor on LED 10 would make it draw 4.6mA at 12V and 10mA at 24V, this is completely out or range of the other LEDs that draw only 1.5mA with their 1K current limiting resistors and 3.3V sources.

I noticed that other LEDs powered by VBB such as LED5 - LED8 on the output FETs are 5.6K. This is more in range if VBB=12V as the LED would be limited to 1.8mA however at 24V it would still be overpowering at 4mA.
I would suggest 6.8Kohm - 10Kohm resistors for R78, and R65-R68 This would provide 1.5ma (6.8K) to 1mA (10K) at 12V and 3.3mA(6.8k) to 2.2mA(10k) at 24V - keeping these much more in range with the other LEDs. Since I personally prefer 24V I would lean toward 10K, however even with 6.8K it would be much more in range of the other LEDs

Another option would be to make R78 5.6K and keep R65-R68 as is at 5.6K but then also reduce the size R10-R13 to 500-820ohms, this would make the green led's a little brighter. I would leave R77 alone because it's fine the way it is and is already brighter than the green LEDs

I realize this is a minor detail, but smoothie should be as good as it can be, and it's also a simple change to make.. no changes need to be made other than to change the resistor values.

Just for reference, I'm using 1.8v for the LED voltage drop and the formula I=V-1.8/R I don't know the exact specification of the LED's used

Fails when connecting heater cartridge

Hello. I have an old smoothoeboard, verson 1 may be?
Iwas working ok but a heater cartridge failed last week. I though the heater cartridge failed so I replaced it but the new one didnt worked. First thing I did was removing and disconecting the cartridge, turned upside down my printer and check the board, all lights looked ok. I turned on the heater and I can see the oboard led (big mosfet q7 I think it is called) ON. I checked the voltage and I can read 12.5 V there.

Soi I connect the new heater cartridge, turn on everything again. LED on the board is on, but I checked voltage on the conector and now there is no voltage there.

So my guess there is some problem on the board?

May be this component is wrong?

Please help me

Stuck thermistors

Not sure exactly what happened, but the smoothieboard released a big puff of smoke, and the thermistors stuck. At 22.3 and 17.7 respectively.

Thankfully we were doing maintenance, and it didn't light anything on fire.

Looks like it was the chip next to c41. I'm guessing a A4982SLPTR-T.

Rebooted and the thermistors unstuck. Still pretty unclear on exactly what happened. Best guess is that it shorted on something, but whatever it was we can't find it.

Anyway, it's worth noting that the thermistors can fail partially open.
