The coordinate change for the origin was correct, I forget yet again that delta's think in polar coordinates and that the origin is the center not the corner of the build plate. I'm not sure on the G code commands but my ini was created using Johan's example, strangely his does not include the coordinate fix with the -100 offsets.
My latest update is that I have the machine entirely assembled and I have begun debuggin the hardware. As far as controlled motion from pronterface goes, I think I'm all set, everything moves as fast as it should and moves consitently in all directions. Weirdly the positive and negative directions for the x and why axis are inverted relative to the buttons on the pronterface gui, the left X moves the printer to the right same goes for the Y, the Z translation works as desired and the homing routine completes without issue.
Earlier today I finished assembling my hotend and extruder, I can reliable set the temp of the hot end with calibrated PID to the range of temps for PLA printing consistently and accurately. Worked out of the box which was nice, because hardly anything ever does when one is engineering ;) My next step was to test extrusion which didn't end up working. I am using 1.75mm filament with a 36mm barrrel makergear hotend with .25mm nozzel. My extruder is a gregs accesible extruder with the bowden clamps that convert it for bowden extrusion. Despite the hotend being up to temp (185C) the extruder can't seem to push the PLA through the hotend. I was told by makergear (after I received my kit and assembled) that bowden cable extrusion with a 0.25mm nozzle would be very difficult and problematic, the neglected to state why any ideas? SHould I try extruding at 200C instead? SHould I get a new nozzle? What is the smallest I can use with a bowden system?
