Wrong direction movement after print job done.

Hello, after the print done I am usually want to go to Z-axis calibration and move the Z axis up to remove the build plate. If I press any button - 1 or 10 or 200mm up, the axis move in opposite direction and the build plate crashes to the vat floor! Nanodlp build 1117

Re: Wrong direction movement after print job done.

Hi,

What is the value of "Shield Axis Direction" in the setup page?
Also check if you have "Debug Info" on "Tools" tab on setup page, click and attach the exported file.

Re: Wrong direction movement after print job done.

I think you are using older version of muve3d settings. Please, update it through setup/tools tab, click on restore default settings.

I believe issue is with your after finish Gcode box. Change it to code below.

M651
G1 Z{[[LayerPosition]]+5}
[[WaitForDoneMessage]]
[[PositionSet {[[LayerPosition]]+5}]]
M84

Something which concern me, as you said it moves in wrong direction even for 50mm which should not happened. I have only seen 50mm up in log file after print, which should be enough even with wrong gcode to send axis to higher level.

Please, dry run and let me know if the issue has been fixed with new gcode. If not it could be firmware issue.

Re: Wrong direction movement after print job done.

Hi Shahin,
Thanks for the replay, following your directions I restored all settings to default. It seems that after upgrade to the new nanodlp version the buttons for up and down movements are set by default to absolute mode, after changing it to relative, everything is OK.

Hi,

Probably you are using older version of muve3d marlin firmware. Absolute mode has advantage of crash recovery and etc.
