I have been doing some digging, found this other thread talking about it here as well.
Well I seem to have been able to get Orcaslicer working on my H2D using the nightly builds. I will test this out and see if there is any differences on vertical holes being printed or if Orca has a setting to compensate for oval holes in the coming days. if my theory is correct why other brand printers don’t have this issue, I’m putting my finger on the slicer software not the actual printer.
