my 6040 experience (yeah, and problems) so far

So I've established that D2 faults even when by itself. D1 and D3 do not fault.

When I use D1 and D3 together, D1 faults (whether it is X or Y axis). Go to about 2:40 to see the problem demonstrated.

I did a prolonged test with the strongest driver D3 on the long axis, almost no graunching noise after 10mins (, except at 9:21 !) video: http://youtu.be/3EQlJWFV8XY

I've now tested some GCODE, same fault. eg zigzg lines don't work on one diagonal.


My 1flute cutters arrived so I had to make my first cut in delrin, 11000rpm DOC 1mm feed 1100mm/min. It was quite loud, the delrin was in a vice clamped to the table. It's all a bit like an aluminium drum at the moment, I will have to add a layer of something once I've thought about how I'm going to clamp my work etc
