So, the good news is that they are probably big enough for the job, as they behave similarly under load and no-load, and have successfully routed wood already. The bad news is that we still have no idea what is wrong: It seems unlikely that both EMC and the tuning software would both produce incorrect pulse trains. All that seems to leave is corruption of the pulse-train between the computer and the drive, or that the drive is not making a good job of driving the servos. If you are in a hurry to have a working system: http://cgi.ebay.co.uk/3-AXIS-CNC-Router-or-Mill-Stepper-Motor-complete-kit_W0QQitemZ280401285543QQcmdZViewItemQQptZUK_BOI_Electrical_Components_Supplies_ET?hash=item41493811a7&_trksid=p3286.c0.m14#ht_1062wt_1172 Your servo system is better in principle, but perhaps you would be better getting a working system then fiddling with the servos when you don't need them? -- atp ------------------------------------------------------------------------------ Come build with us!
