M104 and M109 Parsing errors on Ender KE

General Discussion

Basic Information:

Printer Model: Creality Ender V3 KE
MCU / Printerboard: Unsure-Proprietary Nebula Pad
klippy.log
klippy.zip (1.5 MB)

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

…I upgraded my Ender 3 KE to the new unlocked firmware and immediately saw a drastic drop in print quality. Today I saw that I had no start macro and therefore was not utilizing my auto bed leveling mesh. I tried putting one together, copied and pasted the recommended start and end Gcode into PrusaSlicer, and was met with one failure after another- Unable to parse M104 or M109 as values. If one would succeed the other would fail. I had been printing all morning before the change with horrible results, but still actually printing.
I dont know programming, I am just trying to have fun with my kids without having my nose buried in my computer just to make an articulated cat. Any help with creating or understanding a proper start macro that will draw a purge line and utilize the ABL would be greatly appreciated by me and two little girls waiting on some toys.

It looks like that you are not correctly passing the temperatures from your slicer. From the (messy) log it seems you just call M104 S instead of M104 S200
Check a sliced gcode file to see if the commands are in there and if they are properly formatted.

A word of warning: These Creality machines use heavily modified Klipper versions. The provided information on these modifications is somewhere between zero and zero.

If you are not well versed in Klipper and troubleshooting then I would generally recommend refraining from “modding” it.

I’m not even trying to heavily mod anything. I just want to pid tune my bed and hotend, and implement my abl mesh. Supposedly the newest update is rooted klipper without the Creality paintjob but I just don’t know how to translate from slicer to cfg. I’m trying to learn though, gotta start somewhere
