I used gcode generator switch is on x axis When I try to print I get invalid extruder, the unknown command m900 k0I get this on all 4 extruders?I have 4 extruders With single extruder mm selected
Well, M900 is Linear Advance... it sounds like PrusaSlicer has that setting turned on when it shouldn't.
sorry i left that out its a bigtreetech silent board and touchscreen
so that may be the reason for m900 error?
The 3D Chameleon GCode Genearator doesn't use M900 (which is a Linear Advance) command at all, so not sure where that is coming from. As for the Invalid tool, you don't need to include the T parameters in your gcode... it's safe to replace them all with T0 since we're just using a single extruder anyway. Our code, again, doesn't actually insert any T commands, so it's just a matter of simply replacing all T1, T2 and T3 commands in your gcode file with T0. I don't recognize the UI you have there... what kind of printer is the running and what is the firmware? The Ender 3 Pro has the classic type of display, not a color one.
