Many small drives for that current rating are designed around the Allegro
3977, which is a single chip driver with an integrated translator. It can
handle up to 2.5 Amps at 35V with appropriate heatsinking. If you really

Pulsemotor, 2A/phase 1.7 Ohms/phse. Type PJ55P1U36B)).

I plan on wiring momentary push button switches in parallel with the
appopriate short cut keys on the keyboard. One of the problems I see is
that of providing for the 2 key combination required for the Home-All
function. I assume that the key assignment can be changed in software
and hope som
Great to hear you had such success.
Maybe you can send me a picture of the 3d chips?
