Cura pause at height issue

Recommended Posts

Posted · Cura pause at height issue

Hi guys. I'm pretty new to 3d printing so please forgive the noobiness.

I'm trying to use the pause at layer height script in Cura 4.3.0 (beta) (same issue with the 4.2.1). After checking some threads here I noticed that the most common issue with pause at height was that after resuming printing the Z was 1mm higher than it should have been. I've checked my gcode and it didn't seem to do this, but, in fact, my issue is the exactly opposite. After resuming, the nozzle is somehow going inside the last layer melting it and trying to extrude (but of course it becomes a big mess). Attached gcode, attached pic of the 3d printed failure. I can also attach the project or if anyone has any idea what is going on here I would appreciate it a lot...this is giving me headaches for the last couple of days.

 

p.s. my printer is Cr. Ender 3.

Try to set your retraction to 0 mm at "pause at height options" then let us see if will works on you, otherwise let me know

I already tried this, because with the retraction set to any + value, after resuming, it used to purge some filament and I couldn’t move fast enough to remove it from the nozzle. Even with the retraction set to 0, it still seems a height issue.

 

Last night I tried using the filament change script and it somehow resumes to the correct layer height, since this script does not adjust the Z. The only tricky thing with this is cleaning the nozzle.
