Same step frequency, same drivers same PC same everything.
It might be close to the limits of the EMC step pulse generator (which aren't neccessarily the same as those of the Mach step pulse generator). Personally I think that is unlikely, but the test is relatively straightforward. You could reduce by just a factor of two instead of ten, the key is to drop it by a significant factor on both systems and see if the difference is still there. If the misbehavior is still there, that pretty much rules out step generator limits. -- John Kasunich jmkasun...@fastmail.fm ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
