Problem every 3 prints

Govahnator

Every +-3 times i start a new print without restarting repetier host in between prints, my printer starts a print and does auto level just fine, then instead of moving to the right print location, my x axis goes in the other direction and hits the x axis holder, and my extruder extrudes at high speed until i press the emergency button.

My gcode is :

G28

G29

G92 E0

Any idea what is going on?

Thanks

These 3 lines do not explain it. Are you using Marlin since you said autolevel and I see G29?

Assuming host always sends the same commands I would think if some endstop/z probe may cause this by being triggered at a time it should not be triggered.

Govahnator

you are right i am sorry,

Yes i am still using marlin at the moment but will change to Repetier soon.

The thing is this only happens with Cura engine.

SO you say it is in the cureengine start gcode:-)

To be honest , i think i am only triggering a bug.

I use the exact same Gcode in slic3r(via repetier host) and simplify3d without problems.

If i close repetier host every time after a print, the problem doesn't occur.

Reconnecting resets the firmware. So I assume emergency reset instead of reconnect would also help.

So it might be a firmware bug related to things send at end of print that have effect at next start.
