I can reproduce the problem here, using the ini and hal files that you pastebinned earlier. The problem seems to be related to your stepgen timing parameters (dirsetup, dirhold, steplen, and stepspace), which are much bigger than anything i've tested before. The configs you posted had them all in the 100-200 microsecond range. If i divide all four of them by ten, things look fine here. Here is a halscope plot with Chris' stepgen timings (in the 100-200 microsecond range): <http://highlab.com/~seb/emc2/big-steps/morely-config-ferror.png> And here's the same plot, with stepgen timings in the 10-20 microsecond range: <http://highlab.com/~seb/emc2/big-steps/faster-stepgen-no-ferror.png> Max ferror here is 0.00003, 30 micro-inches. I'm not sure why it's so much bigger with slower steps. I'll look into this some more, thanks for the bug report. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ Come build with us!
