remember that the axis directions refer to TOOL MOTION. ie +Y is tool away from you X+ is tool to the right and Z+ is tool UP
not 'slow and shallow'! calculate the rpm and feed speed for the material and type of cutter. feed at that speed. there is such a thing as too...
it is almost certainly a software problem, but you don't say what software you are using, nor what controller.

thanks, but I thought I had already done a resource for that (-:
I agree with Joe, just build a CNC lathe (-: This gives you the control, and also the future option of making a drum shell that is not just a...
Mark, you have included a file in the examples folder that will fail to cut. SketchUcam Aluminum Examples\Aluminum Box Fold Example.cnc contains...

So, having Sketchup you can add the SketchUcam plugin and go direct from Sketchup to Gcode (-: Get it here (free and open source)...
That is exactly what you have to do, have a a very high angular resolution to match the size of your workpieces. Say you have a 200 step per rev...
I have plans to add 4th axis to SketchUcam... so you would be able to specify an angle (for A or B axis) for a set of Gcode. then you can use...

your step and direction pins are probably reversed there are 2 common pin layouts, one with 'step dir step dir' ordering and the other with 'dir...
GRBL accepts all its instructions via a USB cable and there are many options for sending those instructions since it is all 'just text'....
