Can you contol a servo thru the cheap breakout card?

Mitsubishi drive MR-J2S-10A and it's corresponding servo in step dir mode.

Or do you need something like a Mesa board at that point

Thanks

You can drive a step/dir interfaced servo via a parallel port.

You may not reach the maximum speed or may need to lower
the steps/turn because the maximum step rate will be limited
by the host PCs base thread latency.

Thanks,

I was looking for a harmonic reduction drive to make a rotary axis and came across one attached to this drive and servo. The size looks good, but the servo appears to be extremely small to hold it from cutting forces.

There are some other worm gear reduction parts also that may work. I'll have to look into,

These have a big and strong crossed-roller bearing on the output side, so make a perfect 4th axis.

The 25-B is much easier to interface with a generic servo drive than the 25-C version.

Cool, thanks

@ leon
what are you planing on the 4th
it may take you down to a 100:1 4Nm in Standard stepper
or as they are realy cheep now go fora 12Nm and put a timingbeld 3:1 4bearing Spindle adapter against
this brings you up to 50Nm at very low cost

Probably indexing , not very heavy stuff. Maybe some 4 axis stuff at some point.

then get you a >30:1 precice gear planatary on Ebay
i use only wormgear backlash free from Maedler
or as not the big load simply timingbelt 3:1 as i mentiond above give it a shot

IF YOU can spend the money or are willing for a harmonic drive go for it
nothing better then this
