Try setting everything the way you think it *should* work, then set axis 0 and 1 (but not 2) following error limits to 1000, and see what that does. -- Sebastian Kuzminsky Okay, people.

me the updated BIT files and I committed them to the CVS Trunk. I'll commit them into 2.2 this week and they'll be in 2.2.8 when it comes out (probably this weekend). I also added a note to the 7i43 manpage that MosChip 9805-based parports wont work with hostmot2... -- Sebastian Kuzminsky

+write time) These figures are correct. hm2_7i43.read() and hm2_7i43.write() together take about 100 us, so any servo period above about 200 us should work well with the 7i43. 1 ms is a great number to use. -- Sebastian Kuzminsky One of my most productive days was throwing away 1000 lines
