Eh, on one hand I was going to make some of them, then didn't figure it was worth the time and effort....DICKEYBIRD wrote: ↑Fri Dec 14, 2018 5:29 pmSorry for the thread exhumation Marty but I've been thinking more & more lately about switching my lathe's KB SCR drive over to an AMC servo drive with the +/- 0 to 10V input. It's just lying there under the lathe bench whimpering "Use ME! I'll stabilize your spindle speed & maybe increase your low speed torque too!"martyscncgarage wrote: ↑Sat Nov 18, 2017 8:43 am ....SO, its doable, don't fret, we can make it work. My buddy Bill VanOrden has the equipment to etch PC boards, but its a slowish process. If I could have boards etched and drilled then they could be made available....
Is that circuit you're referring to makeable by us semi-electronically challenged people? I haven't found any commercial signal conditioners online for less than a couple bills. That's twice as much as I snagged the drive for & too much just for experimenting.
It could be bread boarded. We made circuit boards. There were several iterations of it.
What's wrong with your KB controller? I found they worked pretty well....
