Z axis movement
-
I have fitted my Tronxy X5SA with a Duet 2 WiFi. X, Y, Z and extrude work properly( move correct distance in the correct direction). The machine homes properly. But, when I try to print the build plate moves into the print head each layer. G code for the test cube has the Z increasing .2mm each layer.
-
are you saying the z moves in the wrong direction during printing? or distance traveled wrong?
please post your config.g
-
The wrong direction during printing

@drthomasw3 said in Z axis movement:
The wrong direction during printing
when you issue a z move in the web ui. does it move in the wrong direction as well?
if so you need to invert the z motor direction and modify your homing file. you might be homing to max rather than min. -
No from the web ui. The input of a positive Z value results in + movement the bed goes down.

i dont see a reason why it would be moving down before print but up during the print.
unless your g codes contain code that would change the configuration at the beginning. -
Test g code that results in z moving the wrong direction: Did I miss something?

cant see anything in the g code either.
try printing and when its happening pause the print and check the manual movement from the ui again.
-
Ok I will do that
-
Does your homing file(s) contain colons before the commands? The error message seems to show double colons.
Perhaps your z is not being homes before the print, because maybe your homeall file differs from the individual axes. This would result in the z axis only moving towards the z end stop, and not the other way (before homing). Is your z endstop located at min?
-
please upload your actual homing files rather than copy and paste.
