How bout the first 50 lines or so of a sliced gcode file.
-
@Phaedrux
Looking at the gcode file looks like the z height does not change for this one until layer 3.

try a different slicer
-
I just tried a g-code file that I printed last week and worked fine now it does the same thing. It's almost as if the Duet is ignoring the z height.
I have Cura installed although I have never used it before, I may give that a try although I don't see why a g-code file that worked last week just fine doesn't work now. I have been using S3D.
-
Verified, Cura does the same thing.
-
Likely not the issue here since you tried a different slicer but at one point I accidentally changed the dialect for the slicer and things started to go real weird. Some instructions where fine but others were ignored.
Just mentioning it here for completeness sake. -
Please post the first 50 lines, not counting any initial "; comment" lines, of a file that worked last week.

Z1600
just for testing, can you half the z acceleration, jerk and max speed. 1600 is a lot of steps
-
@Veti
Done, no changes.
I have another printer that is down right now for a rebuild, I am thinking of taking the Duet Wifi out of that one and putting it in this machine to see if that makes any difference. I assume all I need to do is swap the SD cards? -
Do you have anything in your tool change files? Tpre tpost etc.
Yes you can swap the SD card for testing. I was going to suggest trying different drivers but if they move normally during other moves just not a print something else must be wrong.
Can you send m906 and m913 during a print to check motor currents?

@Veti
You were on to something Veti, I removed the Z Offset for tool 0, no change, so I removed the offset for tool 1 as well now it works fine.
I know there is a way to set tool offsets in the tool change files but not sure how to do that.@Phaedrux
Here is what is in my tool change files. The tool 0 files are the same aside from to tool pickup/drop off locations.tfree1.g

@Veti said in Strangest issue yet, Z not moving during print:
G10 P1 X0.99 Y1.2 Z0.8 ; Reset tool 1 axis offsets
what you are configuring there is that the nozzle is 0.8mm above 0.
so in order to print it would have to move 0.6 (assuming 0.2 layer height) below zero.
yet normaly movement below 0 is forbidden (for good reasons) -
@Veti
Yes, so I have two tools that get picked up by the tool head like what is done in the E3D tool changer. I am using a Bltouch as my Z-probe and it triggers the nozzle is around 0.4 to 0.6 above the bed so I applied those Z offsets in the G10. I may not be doing it right though.... -

It was changed in rrf to allow you to set the min and max in a single line and that is how I do it on my CoreXY printer. This is my m208 line which works perfectlyM208 X-5:340 Y0:334 Z450
