leeotts / ender3v2-klipper-configs Goto Github PK

First I want to say THANK YOU for your Ender3v2-Klipper-Configs repository. I have an Ender 3v2 with a Sprite Pro and CR Touch installed. I was running a very stable Mainsail OS/Klipper/Klipper Screen setup until someone decided to hit the "Update All" button for me. Long story short, the current Bullseye-based version of Mainsail OS broke everything.

My backups turned out to be corrupt so I was looking at a long painful process of redoing my bed mesh and all of my tweaks. Your repo saved me a lot of time getting back to zero, but I did come across a minor issue with the printer.cfg file.

The line under the header

[mcu rpi]
serial: /tmp/klipper_host_mcu

causes a communication error between Klipper and my Creality 4.2.7 board on bootup. I was going nuts for a few hours trying to figure out why Klippy kept failing to connect. I started going through your printer.cfg file line by line and came across the mcu rpi section. Klippy was failing and logging "Mcu 'rpi': Unable to open port: [Errno 2]" so I thought just maybe that is the issue. I commented it out and BAM everything worked again.

I am by no means a coder. I know very VERY basic things. I think that line works with the input shaper code around it, so I just commented that all out as well. I haven't started messing with shaping yet but it's on my "to learn" list.

Anyway, I don't think this is a bug per se, but might be worth a note somewhere for future novices.

Sorry for the long-winded message, and thank you again for the work you put into this repo.

First of all, thank you for the configs, they are extremely helpful. Just wanted your input regarding what changes I need to make if I do NOT have the Sprite Pro. I have been doing a lot of googling, but can't seem to nail down everything.

Definitely the max_extrude_temp setting and rotation_distance

Anything else I need to be aware of?

Thanks again. Appreciate you sharing this.

Would not define the object. I found that I needed to add a line into the start macro "exclude_object_define". Is this intended? Aside from that the rest of it worked really well but that tripped me up. Is it supposed to trigger somewhere else? I also tried adding M117 before the start macro in my slicer and that did not help.

Trying to use your macros.cfg, but every time i get Move exceeds maximum extrusion (1.011mm^2 vs 0.640mm^2). I use CURA. What should i do? Thank you!

I'm trying to use your setup for my ender 3v2 v4.2.2 board with the sprite pro extruder and the CRtouch.

In the extruder section of your printer.cfg, why do you have this commented out?

#control: pid
#pid_Kp: 23.561
#pid_Ki: 1.208
#pid_Kd: 114.859

I can't get klipper to start with that commented out. I just uncommented it to get klipper happy.

Also, you have the following commented out as well in the bltouch section ?

[bltouch]
sensor_pin: ^PB1
control_pin: PB0
x_offset: -31.8
y_offset: -40.5
#z_offset: 4

Can use with modified Ender 3 V2 printer, with the Sprite Pro Extruder, CR Touch, but with 4.2.2 board?

Need any changes?

Thx, grate job!

When starting mainsail I now get the followijng error message

Deprecated Klipper Option
Option 'max_accel_to_decel' in section 'printer' is deprecated and will be removed in a future release.

Sprite Extruder Pro has a gear ratio of 3.5:1

Hi Lee,

What would need to be changed to use this package with a 4.2.2 board? Thanks!
