Pressure Advance Settings with Ramming

[Mawe066]

Is your feature request related to a problem? Please describe. When Ramming with Multiple Colors is activated, it sets Extruder Pressure Advance to 0 without Extruder information, which causes an "unable to infer stepper" error in Klipper.

Describe the solution you'd like Add Extruder information to pressure Advance setting for CP Tool head Unload

Maybe I am just to dump or overlooking something, but I had to disable ramming because it's triggering an error in Klipper.

By the way, is there any time zone you can estimate version 2.7? I would love to have organic supports.

I think end of February is not too pessimistic. My original plan was to finish the 2.7 by december, to use that in january. But I couldn't make it, so I had to dedicate my january to stabilize the 2.5. I think the 2.5 is now in a good shape, and i can return to 2.7 merge.

Sounds awesome, definitely looking with excitement to it and that you started development again after almost a year of silence around Super slicer. Tuning my wipe tower for full 3 days and still can't figure it out yet. Sometimes my filament gets stuck, maybe because of bad tip shaping, which is weird, because I use an cht nozzle. There is not really a Tip 😅

Quick update: I used the wrong expressions. In the filament gcode I used {tool_name} instead of [tool_name]. Now it works as expected

[supermerill]

It's weird that it's different. [var_name] is just the old syntax for {var_name[current_extruder]} and {var_name} also is translated to {var_name[current_extruder]}

I don't know, but with EXTRUDER={tool_name} it does not work and with EXTRUDER=[tool_name] it works perfectly fine. Here a picture of my setup.

Edit: Picture upload did not work properly, I will copy and paste my code later when I am at my PC

Sorry for my late response, i dont had the time since. The Issue that triggerd an "unable to infer stepper motor" was caused by SET_PRESSURE_ADVANCE ADVANCE=0.0, which is caused by:

;Filament GCODE ;PLA PA {if tool_name == "extruder"} SET_PRESSURE_ADVANCE ADVANCE=0.750 SMOOTH_TIME=0.040 EXTRUDER={tool_name} {endif}

{if tool_name == "extra_extruder1"} SET_PRESSURE_ADVANCE ADVANCE=0.750 SMOOTH_TIME=0.040 EXTRUDER={tool_name} {endif}

{if tool_name == "extra_extruder2"} SET_PRESSURE_ADVANCE ADVANCE=0.750 SMOOTH_TIME=0.040 EXTRUDER={tool_name} {endif}

{if tool_name == "extra_extruder3"} SET_PRESSURE_ADVANCE ADVANCE=0.750 SMOOTH_TIME=0.040 EXTRUDER={tool_name} {endif}

I changed it to following, what for me, fixed my issue:

;Filament GCODE ;PLA PA {if tool_name == "extruder"} SET_PRESSURE_ADVANCE ADVANCE=0.750 SMOOTH_TIME=0.040 EXTRUDER=[tool_name] {endif}

{if tool_name == "extra_extruder1"} SET_PRESSURE_ADVANCE ADVANCE=0.750 SMOOTH_TIME=0.040 EXTRUDER=[tool_name] {endif}

{if tool_name == "extra_extruder2"} SET_PRESSURE_ADVANCE ADVANCE=0.750 SMOOTH_TIME=0.040 EXTRUDER=[tool_name] {endif}

{if tool_name == "extra_extruder3"} SET_PRESSURE_ADVANCE ADVANCE=0.750 SMOOTH_TIME=0.040 EXTRUDER=[tool_name] {endif}

I dont know if thats on purpose, or its in fact a bug, but there you go

[supermerill]

can you send me the generated gcode by both versions?

[Mawe066]

Hmm thats weird... I just inspected the Gcode and there is no difference, but one works, one not... I dont get it..

[supermerill]

they are really similar? maybe there is an invisible character.

[Mawe066]

What do you mean with invisible character?

[Mawe066]

ah okay, maybe was there the issue...
