Help to figure out mach 3 Dc spindle control to Acorn Dc spindle control
Posted: Thu Feb 08, 2018 6:33 pm
Hello I have had control of a DC spindle in Mach 3 with the help of Littlemachineshops 4213 spindle speed control board with a Littlemachineshop variant of the x2 mill(l.m.s 3990)
Now that I am moving to acorn and away from using the g540 I am using DMM servos and drives to the acorn. I want to figure out the spindle situation. I want to get feed back and or guidance so I can lessen the chance of killing either the acorn or the spindle control board.
In the schematics I see a hook up diagram for a VFD and KBIC board spindle control and that's it. I had control of the spindle in mach 3 forward and reverse(hooked up to a G540 just like the picture). It took trial and error because that G540 to 4213 diagram wasn't on Littlemachineshop's website until I asked about it and after trial and error I figured it out.
The 4213 board doesn't have any relays as someone on this forum mentioned some dc controllers switch polarity to change the direction of the motor. This set up is one of them in mach 3( see picture) I used output 2 for m3 and m4 and it worked(don't know how).
Franco tried with his factory dc motor controller and fried part of the acorn board as he said in one of his videos so I'm a little hesitant to just wing it. Is it possible with my set up?
