Thought it may be a great kit to start on so I bought one and finally got it all put together. Total noob, first time with the hardware and the software. I have a few questions I have been unsuccessfully searching the forums for. HARDWARE/SOFTWARE? My first project was a single letter M in 1/2 in. MDF, but I had to do some sanding because the 1st pass was slightly off from the rest of the passes (it made 8 passes, probably shouldn't have checked that one box). I can't figure out why the first pass was "off" though. (It was just a little farther to the left than the rest of the passes.)? SOFTWARE? The second question was how to make the 3D projects? Say I wan't to make my single letter M have dimension. Or make the water drop like the demo picture? The SketchUCam tutorial says that the drawing needs to be on a single plane or it won't work. Or I just didn't listen close enough. So how do you go from 3D Sketch to G-Code to put into GRBL Panel? SOFTWARE? Okay, last one, until I get some limit switches I mean. Wiring my stepper motors incorrectly/backwards on a couple of axes and hearing the grinding/clicking noise when running some test g-code made me research limit switches. Anyway, the software question is why won't the GRBL Panel keep my changed settings? I have changed them 100 times to match the picture, but they keep reverting back to the originals. I have double clicked everywhere, tried clicking the refresh buttons located elsewhere (Those settings seem to stay changed.), but the $ settings all revert back to the originals. The only thing that I haven't tried is getting the arduino software to try and update the settings outside of the GRBL Panel software, but I will do that if it is my only option. Thank all you CNC gurus out there for any help you're willing to give. I'll keep searching for answers. I bought the C-Beam Bundle w/ stepper motors, CNC Pro V2 controller/driver, and 12v power supply from the OpenBuilds part store.
