Is exactly what came with the machine. The wiring diagram is in it twice, but nothing on the PCB's. >From the sounds of it, its a scr or triac control. More evidence of that in the fact that the reversing switch is wired to the motor. The rpms display is driven by a single slot interrupter from a disk with round holes drilled into it on the top of the spindle. Eg, no room for a disk like I put on the lathe, but the top cover of the gearbox could be machined away to do something similar, but would need me to design a new pcb to mount the slot interrupters. That means their speed display will not work but since we can do that with linuxcnc, thats no biggie. Yet TBD whether I rip out their speed control and put in one of the Pico servo amps. I am extremely pleased with how it worked on a similar sized motor on my toy lathe. It sure simplifies the reversal as that servo amp handles that with no relays to putz with. The motor kit came Friday, and thats the first Nema 34 motor I'v seen, it will go on the z axis. Buying the package like that sure makes it nice. Looks like all I'll have to do is mount the stuff and wire it up. Its 2 each 470oz/in nema 23's with 8mm shafts, a 1600oz/in nema34 with a 12mm shaft, 2 ea DM542's and a 42 volt PSU for the nema23's, a DM860 and a 60 volt psu for the nema34, and a bare bones but all opto, breakout board. On fleabay for a tad under $400. I just got to get me back into working condition. I pulled something loose in my game knee and back getting it into position in the garage. Thanks Belli Button.
