Most interesting (and strange) ... taking the same object and slicing it in a new copy of the same printer (CR-10) produces the right code. Even taking all of the pre-amble g-code from the old printer and sticking it into the new printer setup results in the proper g-code output. I do not know what 'exporting a project' is - can you give me a hint on how to do that ?

ahoeben - Any thoughts about the example code I posted ?

Attached is the heavily edited gcode file for a little square test coupon that I use for setting up things. All routine moves have been edited out with '<snip>' comments. The gcode file has been cut off after the z offset section. Z offset was for 200 mm to make it obvious. Hope that helps! CCR10_coupon.gcode

I sit corrected, the gcode for the Z offset is in fact in the file, just not where I would expect it to be. Turns out it is right after the comment (presumably by Cura) "Layer 1". The problem is, layer 1 is in fact the second layer and the Z offset needs to be applied to the first layer.

I was just trying this plugin with Cura 3.2.1. The z offset field shows up, I can enter a value (although there is a very limited negative range) but the resulting first layer print height is unchanged. There appears to be no modification to the gcode file that is generated for the print. Is there anything that I could have possibly screwed up in the install or with my custom pre-amble gcode ?
