Use with 4.2.2 board

[jeremy-niles]

Hi Lee,

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

I have an Ender 3 V2 running the stock 4.2.2 board, with a CRTouch and Sprite Extruder.

I was able to install these configuration files just now (with a few features disabled such as KAMP...for now) and can confirm it's looking good so far, I don't actually see any obvious differences between the instructions for 4.2.2 and 4.2.7.

Klipper has successfully connected to my printer and it's showing the current temperatures. Next up I need to run some calibrations, then see if I can get a print going.

Edit: I take that back, as soon as I tried to home the bed nothing happened. Turns out the pins on 4.2.2 are different, as per #8
I copied over the step_pin and dir_pin settings from here and that fixed it: https://github.com/Klipper3d/klipper/blob/master/config/printer-creality-ender3-v2-2020.cfg

This is the way... you will just need to change those pins for xyze

It's been printing great so far! I've performed the bed screw calibration and dialled in my Z-offset, had some slight issues with the START_PRINT macro because I forgot to untick the "Emit Temperature commands automatically" setting:

Also successfully calibrated pressure_advance and saw a noticeable improvement in corner quality.

I did make a few changes to the order of operations in your START_PRINT macro to match what I had previously but otherwise it's the same. KAMP is working brilliantly too, wouldn't have known about it if I hadn't come across this repo. 🎉

Oh, I don't use prusaslicer. I use cura. I will note that in the next update, I am about to push out.

Yeah I notice significant improvements when I dial in pressure_advance as well too. Have you tried input shaping?

I love KAMP. I always hear great things but thought it would be to difficult to implement when I just started out. I was wrong and it has only been made easier to install. Kyleisah's hard work and contribution to the Klipper community is truly commendable and makes a valuable impact

I added a 4.2.2 board configuration to the repo. Change the file name to printer.cfg

I don't have a 4.2.2 board, so use it at my own risk. Let me know if it acts funny, and I will make changes, but I just changed pins to match a 4.2.2 config. Everything else is the same, so you must still add the remaining files to work as intended.
