Suicide dive when extruding fast (for changing filament)

VedaVeda
edited October 2017 in Bug Reports

Using a Pi 3 in combination with Repetier server 0.86.2, a Kossel delta printer with Radds microcontroller.

I've noticed some strange behaviour. When I press extrude fast 100, the printer makes a suicide dive, it tries to push the nozzle into the bed. This happens when I use the server to extrude, but also when I use the filament change option. With distances lower then 100, it does not happen.

When using repetier host, connected to the server, everything works perfectly. Does anyone have ideas?


EDIT: It is basically the same error as dot_bob

    Please check the log. Enable commands in console log and do your extrude and check what commands get send. First thing to isolate is if the server is sending wrong gcode or or firmware is interpreting something wrong. To prevent problems with long extrusions being blocked by firmware, the server splits such moves into several commands. So first suspect is that this contains some move command. Looking into the code I see that it would issue a xyz move with same position as shown in the interface, so normally that would be 0 move. If you had homing z position stored as 0 in server config that would mean after homing it would try to go down to 0. In that case just set homing z position correctly.

    Ok, first 1 retracted 100, then pressed extrude 100 @ 30mm/s then the emergiency stop. This was the result:

    I think I figured it out. In Repetier host I've set my home position to be x:0 Y:0 Z:394,10.

    I've since set it on the server, and now it works  :D
