Yes, I use S3D. The dimensions are never true when I print on the KnP, either. If I make the same part on both the Qidi and the KnP the Qidi is accurate but not the KnP. I'll check out FlashPrint and give it a shot if they have a free version. Not sure I want to pay for yet another slicer.

BTW, I am using the Makerbot Replicator dual profile in the slicer. Is that what you use?

Just suits the machine better than simplify3d.

Flashprint lets you adjust internal and external gaps. So you can fine tune them untill the gears don't stick.
