General Mach Discussion / Spindle setup - help
« on: February 28, 2008, 07:27:08 PM »
Hi -
I have a mill conversion on the go -

What is the preferred interface for the spindle speed control ? (step/dir or pwm)

It has a servo motor on the spindle - does anyone know if I can drive this with a gecko servo drive (or will it not go fast enough) ?
The servo is about 60volts and 500 step rev encoder

And what is the max number of steps a second that mach3 might do ?

Best regards
Dom @ Australia

General Mach Discussion / Mach not completing moves ?
« on: September 05, 2007, 06:48:59 PM »
We are using ver 1.8? and have a problem.
With multi passes the axis does not return to zero before start the next move.

We thought that it maybe losing steps but this is not the case - as you can still send it home and it will go back to the orignal position ?

We are moving at over 7 metres a minute ..
The problem goes when speed is reduced to 2 M a min

Any ideas - should we upgrade

Cheers
Dominic
