Extrudes when I tell it to, does not when printing

Heyyy guys,


This is my sitch: when I raise the Z axis and tell the printer to extrude after heating up, it extrudes fine. The motor drives the gear and hobbed bolt works and material gets extruded. The bearing is spinning (I marked it).

When I start printing, it feeds for a bit, then the bearing stops spinning and the hobbed bolt just chews into the filament. Then no more extrusion....


Any ideas where to start? This is my third full day of work at work trying to diagnose this thing and get it to work.

 

What does your first layer look like.

 

First layer is fine. Did a calibration circle in mattercontrol, all is well. Back in simp3d now, its printing a super thin ghost layer...gear is spinning but bearing marks are not. Is it too close? Is there a way to calibrate simp3d before a print the way that mattercontrol does?

 

Add an offset after G28 to your startup Gcode

eg

Code:

M565 Z-1.0    ;1.0mm offset

 

Thank you Mike! You are the hero of this forum.

Going to do the simpl3d calibration....idk how I never did that yet (fail on my part)

Should I have to enter this code before each print or is there a way to save it?

 

For the FFF settings (Edit Process Settings) go to the scripts tab, there' you'll see the Starting tab. That has the startup Gcode there.

Just add the M565 code after the G28. This will save it for all prints.

You could also add G29 after the M565 to do auto bed calibration.

Not familiar with simplified 3d's calibration if any. I just use the one in the firmware.

 

IT WORKS. ITS FINALLY KICKIN!!!

YOU GUYS KICK F***ING ASS!!


Thank you very much!!
