Hello all,I'm definitely a noob and just finished my Pegasus 10 build. I did go for the Z-axis upgrades with the heated bed. The first test cube went well from the gcode file in the Makerfarm Pegasus software collection. Then, I ran the cube STL through slic3r locally as a test. That cube also ran well, as did a sleeping dog that I downloaded and printed for my wife and a relay board mount file (also in the Makerfarm software collection). Then, yesterday, something changed. Zsteps is still 800/mm, but the Z axis is moving several times more per increase than it should. Parts that I printed yesterday were not solid, and I thought my slic3r settings might be messed up. This morning, I decided to print the original Makerfarm-supplied cube gcode. About halfway through, the 'structure' was about 60 mm high. X and Y looked to be moving as they should, but Z was jumping more than it should with each layer. Recommendations?Regards,Stan McIntosh
