Scaling causes printing in air
Hello. First, I'm very new at this, so forgive me if I've overlooked something obvious. Also, I really want to thank the Repetier folks for their hard work in making a nice looking, very functional set of programs. You guys rock.
I have a Rostock delta printer I recently built and got working. I've successfully printed a few small things, and am in the middle of figuring out auto bed leveling and correction.
If I load an object downloaded from Thingiverse, it displays and prints fine. I was printing a servo arm for mounting a z-probing switch last night and found that it needed to be about 1.2x larger for my setup. I scaled it to 1.2 on all axes in Slicer, re-sliced it, and tried to print. It ended up trying to print it a couple of inches off the bed, although on the screen it still showed that it was sitting flat at Z=0. Eventually, I tried scaling only X and Y, and left Z at 1. That got me what I needed, but can someone please explain what was going on with the height shift when I scaled all three axes? Thanks!
