Cura 3.2.21 stretches X in gcode

Post by kek » August 4th, 2018, 11:57 am

OK, I've spent the past hour and a half searching the web with no luck:(

I was using Octoprinter to control my Lulzbot TAZ5, but since Octoprinter doesn't support Cura 3.2.21, I'm now direct-connecting to the printer.
When I load the stl file Cura correctly displays the envelope dimensions, however when the parts print, they are stretched in the X direction by about 25%.

Any ideas on how to correct this - short of manually scaling the model in the X direction to "fool" the slicer?

Kind regards,
Randy

Think I am missing something here. I use Cura 3.4.1 (and have used 3.2.1 in the past) to connect to Octoprint with no problem. Are you using Octoprint to do the slicing? If so, that is using a very old CuraEngine (prior to Ultimaker taking over development). Recommend just slicing on PC and sending the gcode to Octoprint.

The plug in was bad. Remove it and install the plug in again. Or go to the newer version of cura

I've given-up using Octoprint and am now direct USB connecting to Lulzbot TAZ5 - this is where the problem of stretching occurs: BTW it is "Y" not "X" (got my directions mixed-up)

The "Propare" tab selected, the envelope size is correct, and the part "looks" correct (ie. no stretching in the view port). This is what leads me to believe that the Y-stretching is happening in the gcode.
