Hi,
just finished building a new controller and a few questions popped up;
For some reason this new controller will not work with the two Thinkpads I've used previously. Had to plug in a 'real' pc . Here's some interesting numbers for the Maximum reasonable feed rate.
Thinkpad 300mhz; 45khz
Thinkpad P166; 22khz
p166 clone; 23khz
3.2Ghz P4; 22khz.....
Any ideas why the P4 is so slow?
Unless I can figure out why the laptop doesn't work with the new controller I'll have to get imaginative. Presently run motors very smoothly at quarter microstep and a high axis step rate/ acceleration. 22khz won't support that.
