HI Mick,

We should thank you and many others for taking up and trusting this relatively new design. Do elaborate on the tests you have done and the parameters you have set.

Irfan,

i was hoping to upgrade my power supply to around 100 volts

before posting a reply but hav'nt managed it yet,

[/LEFT]The only parameters altered from the defaults are H 4000 and E 30,

the 70 volt motor has massive torque in both directions.

The only testing done was with a small Gcode subrutine varying speed
and distance, this was running for about an hour,no o counts.
The standard encoder 200 cpr is connected with the SN75115 removed

and jumpers from the socket to j1 j2

.

MACH3 is running at 25 kc,steps per mm 630, velocity 2164 mm the
acceleration was lowered until there was no error tripping.

rgds mick.
