Setting Z lift to 1mm helped some, but it would still occasionally bump into a lower layer. It turns out the problem was indeed over extrusion. When I looked at it closely, the first layer was quite rough with lots of peaks. It had a texture almost like a rasp. Before I started using BuildTak, I had some problems with first layer adhesion. I ended up following this advice from S3D: "if you entby alangibson - Duet
Quoteo_lampe You can use "z-lift" on travel moves to avoid this. Makes sense. I'll give this a try this evening. I wonder though if this is evidence of a mechanical problem somewhere. It seems like, assuming the mechanics are perfect, the only way this problem should come up is if the layer is warping or peeling. I'm using a 0.8mm Volcano nozzle, so maybe this is laying down so much plastic thby alangibson - Duet
I've run into a strange problem while trying to calibrate my Kossel XL + DuetWifi + IR Probe delta. At some point while printing the second layer, the hot end invariably crashes into another part of the second layer. I've got Simplify3D set to 50% first layer height. The first layer goes down fine; there's no visible curling and adhesion is good. The second layer starts printing fine as well, buby alangibson - Duet
I'm driving my no-name Kossel XL delta with dc42's RepRapFirmware v1.17e running on a (awesome) DuetWifi. While trying to get rid of some dimensional inaccuracy, I noticed that M122 reports that 'Bed compensation in use' is 'none.' Does this mean what it sounds like: that the bed was probed but no compensation is being applied? === Move === MaxReps: 6, StepErrors: 0, MaxWait: 1282724ms, Underruby alangibson - Delta Machines
