M600

[gfrcr]

Good afternoon, I have a k1 max and I have been using the script since the beginning to have full control via klipper, however one thing that always bothered me was the m600, 95% of the time I print and I want to change the color with the m600. printer clogs, it's amazing, can anyone tell me what could be wrong or even what to do to prevent this from happening?

I'm having the exact same issue, even with the pause command. I'm still investigating... I figured so far by looking at the printer settings and the OrcaSlicer settings:

1. The helper script has a modified version of the gcode_macro QUIT_MATERIAL, I'm testing right now the factory one. The modified one seems to try to make a "tip" when retracting and this could be causing the clog.
2. OrcaSlicer has two features that I noticed that seems to interfere with the printer settings. One is to purge into the prime tower (it seems to create a large blob of filament after resuming) and another one for also creating a filament tip when changing filaments.

These are untested, I'm running another test print but I had to unclog the printer four times last time.

Hey I was having similar issues using the M600 cfg. The issue seems to be in the gcode_macro _UNLOAD_FILAMENT. The extruder movements are all over the place and just begging for a clog! I replaced the FOURTEEN separate Extruder commands with one extrude and one retract command as follows:
G1 E50 F180
G1 E-100 F180
and it seems to be working well now! Your mileage may vary and you could even remove the first extrude before the retract that I have.

The trouble comes from trying to edit the Helper-script/M600-support.cfg as it's read only. The workaround I managed was to download the M600-support.cfg file, then change the Unload filament Macro values, then reupload the config file to the config root. Finally, you'll have to go to the printer.cfg and change [include Helper-Script/M600-support.cfg] to [include M600-support.cfg].

Hey! Same problem. I noticed that the difference between the standard macro gcode_macro.cfg/QUIT_MATERIAL from the firmware 1.3.3.46 and the macro ‎/Helper-Script/M600-support.cfg/_UNLOAD_FILAMENT is in the line G1 E10 F300.
In gcode_macro.cfg/QUIT_MATERIAL it's G1 E100 F300 and with this value it works as expected for me. I also tried an in-between value E50, but I've had some difficulties getting the filament thread out, so I decided to stick with E100.
