All my prints start high

All my prints start really high. I have to manually lower the z axis while its printing the skirt. How to i fix this?

I have the new self leveling machine.

Using MatterControl with Slicer.

 

Reduce your Z offset

 

Thanks. Sorry for being such a 3d noob.

How do you do that? In slicer settings?

Does someone have a good list of settings to check in slicer? I'm getting ok prints but not great.

 

Should have been this paper that came with your printer describing how to do the z probe offset

 

Thanks! I'll give it a shot. Is slicer the best slice program to use?

 

I use cura and put this gcode in the startup:

Code:

G1 Z0.5   ;Adjust Z offset (set to 0.5 for mine)
G92 Z0    ;Define new Z home
G29       ;Autocalibrate bed

 

Thanks again. I'll try these and see what I get.

 

Still really high. I mean like 4 mm off the bed.

 

its been since i upgraded the firmware on the robo this morning. How do i go back to the last firmware?

That helped a little. Now it is only 2mm off the bed. Here is my gcode. What am i doing wrong?

G28 ; home all axes
G1 Z0.5 ;Adjust Z offset (set to 0.5 )
G92 Z0 ;Define new Z home
G1 Z5 F5000 ; lift nozzle
M109 S[temperature] ; set the extruder temp and wait
G29 ; probe bed

 

I can't figure this out. Until now I haven't used the auto leveling, just printed normal and adjusted for hand while printing the brim.

I used this code since I also use Cura, the leveling works med the offset don't. It basically drags the nozzle in the glass whatever I do. I tried your 0.5, I tried 0.9, 1.1 (that's what my note from Robo had), 2.0. I even tried 5.0 just to see if anything changed. It didn't. All the same. I tried changing z-offset in my XXL-controller. Didn't do anything either!

Anyone who knows what I might be doing wrong? Would love to get this working so I don't have to do it by hand!

 

You flashed the firmware from the link I provide?

Message me on skype, it's in my information
