@thekarlmiller I do this with a Duet3, should be the same with a Duet 2 board. You need to set the printer parameters in MatterControl for your specific printer. If there is no preset, choose Other > Other.
You will have to modify your gcode post export. Use Notepad++. Scroll down your your start code until you see M400, M107. Insert G29 S1 into the gcode and save it.
Upload the gcode through the DWC as normal afterwards.
PLA is known for high shrinkage, on average you get about 1.6%
So i now always use PLA Pluss and now only get about 0.2 -0.3% shrinkage
Remember different brands either have better or bad quality PLA
I use Esun PLA+ which has very good properties and strong, I have tried Tronxy and I have found it bad & unusable for my models
Maybe some one could start a post on filaments that work best for there printers and models.
Im having a similar problem Matter control come to a crawl when adding supports. with no supports then fine
can not do anything when added supports to any of my models
and when you do finally get to click on the print it also takes forever to print. either directly or to an SDS card.
never had this problem on earlier version before May 22 release .
oh it does work ok on models less that 100 x 100 size
Printer profile im using is an Enders 3v2
