G1 H1 for extruder

Aurimas

Hi all,

is it possible to have homing for the extruder just like other axis?
need to push the filament until it hits the extruder and then stop
is it possible?

Have you seen this?

@Phaedrux sorry I was not clear enough - I need switch activation for detection - stall will not work in my application
but this partially answer my question G1 H1 E is possible. just need endstop definition for this, but it looks like M574 cannot be used

the other option would be to use Meta commands, something like:
while Alarm is off
G1 Exxx

and loop until the alarm activates and exits the loop
any other ideas?

@Aurimas If this is for a start up situation you could just initially set your extruder motor as being some other linear axis then set an endstop for it, do the "home" and then remap it as an extruder? Not something I've ever tried but it would probably work.

@gloomyandy thanks.
I waas hoping for a little better option, but if it is all that can be done this will have to do it
