Hi Pete,

i did get a response from Leadshine, it was about to how to correctly calculate the steps/inch and not really a diagnostic approach. in the software set up for the leadshine i thought i read that the minimum step pulse time was 5ms and i think mine is set there but ill have to double triple check that..... my old set up got hot and was noisy. not that that's bad, just smooth, cool and swift is definite positive upgrade.

i dealt with this fellow named chris and he was easy to coordinate and verify that the kit was correct for my application. came in about a grand for the motors, drivers, power, interconnects, and motor/encoder wires. i built a case and re wired everything.

i need to steal a few hours from the rest of my lifes draws and tinker with it. ill have to get back to you for a complete fix.

how do we post pics....?

Hello,
i just installed a pair of ES-P32320 kits as my X and Y axis and nema 34 with an 808 as a z. what mach settings in motor tuning are appropriate. these are replacing open loop steppers and the settings i have vastly different to get them to move. the leadshine's are installed at stock factory recommended dipswiches. ~2000 steps/inch old open steppers @ 1/2 steps bipolar parallel and ~40000 steps/inch with leadshines.

what did i miss? it works awesome. maybe i should just not worry about it but this detail i cant reconcile.
