Well the upload image box seems to allow me to select a file then it sits for a while and dissappeares, I give up on the picture.

I'm quite confused about some issues I'm having, I've turned my speed on non print moves way down and have never had signs of missing steps. I'm not sure it's a software problem, but I've fought this a long while now. Machine is a rostock max v2 and using mattercontrol 1.5.0.6404

I often have the nozzle drag across parts. In the beginning it was largely due to loose parts, but I seem to have those issue mostly under control. I have changed the Z lift value and it seems it only does anything during a retraction. When jumping between parts or across parts it drags. Often it only leaves a small line, attached is a picture of a part that it ruins. I confirm the nozzle crosses the part at the layer height in gcode. Makes a bad noise on this part.

Next is the Hollow calibration pyramid is globs up really bad on 2 the pillars at 10:30 and 4:30 (positions on an old analog clock, probably have to drop this terminology soon, lol) the other 2 moves it retracts the filament when moving to the 2:30 and 7:30 pillars.

So is the nozzle not supposed to lift in rapid moves? Or only during retraction? And why does it ignore the minimum length of move to retract. Am I asking to much of a printer?

Thanks
