Can I power the extruder heater pin if I haven't connected heater on this pin ?

[bleak token]

Hi, I'm trying to build a clay printer.

I'm using a frame of Sunlu S8. I didn't need the heating extruder so I remove all the parts.
But klipper don't let my run my new motor extruder if I didn't set heater extruder.

So, can I power the extruder heater pin if I haven't connected heater on this pin ?

No that will not work ... if you do not have an extruder than do not specify one ...

I guess the only real way would be https://www.klipper3d.org/Config_Reference.html#manual_stepper

but than you need own macros for G0/G1 and G92

There are way around it with setting up an extruder, with heater and thermistor and let both open.

for that you need to set the min_temp and min_extrude_temp to e.g -250 and you need to insure that you never try to heat the extruder in you gcode file (otherwise you will get an klipper shutdown)
