Topic: Z- offset problem. Please Help

I run the z offset calibration in soliprint and everything looks good.  Then I run a print job and the printer prints a few mm above the print bed.  Same thing happens with RH 0.85. I keep re running the z offset and trying to fine tune it but it still prints a few mm of the bed. Any suggestions? I had everything working before I switched to printing on a different computer.  Thanks in advance.

In SoliPrint, after running the calibration print, make sure you are selecting the best offset and setting it.
We should be releasing SoliPrint v1.2.2 soon with a slightly updated and (hopefully) easier to understand calibration process.

Re: Z- offset problem. Please Help

Thanks for the tip. I have been selecting the best offset. I don't think that is the problem.  It seems like the auto level isn't running when I do a print.  Because the bed hangs, the print head is printing higher off the bed in the front than in the back.  What else could cause the print head to print too high?

Re: Z- offset problem. Please Help

Unless you've changed it, your start code should have a G29 command which runs the probe. Be sure that you don't have any G28 commands after this as it will cancel out the measured data, especially if you're printing from gcode (as opposed to loading a model and slicing it).

Re: Z- offset problem. Please Help

This is my start code.  What is your start code?


G21; set mm units
G90; set absolute coordinates
G28 ; home all axis
G29 ; Bed Check - Z-OffsetG9
G92 E0 ; reset extrusion distance

SD tells me the proper start code should include:

G90
M100
G28 X0 Y0
G29
G92 E0

Note the G28 comand has parameters. If you omit these, you'll see a message reurn from the printer to home XY before Z.

Thanks for all the tips. I used the  start code below and made sure my print settings in slicer we edited also.  I am now up and printing again.
