Centroid Community CNC Support Forum

Hi Keith, Let me make sure that it is clear to everyone that my PERSONAL mill (the Prototrak) was an Allin1 DC retrofit I did myself, and the one we are having trouble with is at my place of employment; a Clausing branded knee mill that originally came with a Fagor 8055 "conversational" co...

What are the thru bore sizes? I'm looking for a rotary that can pass 2.000" thru
Are the servos AC or DC?

I might have a unique perspective on your question. I am a journeyman machinist with just shy of 3 decades of experience in the trade. I have direct experience with BOTH configurations, each being controlled with a Centroid CNC control. In addition, and I feel an important detail, is that I also ran...

Yeah, MachinesUsed had a RZ-160 up for auction a couple months ago. I was excited because it listed the thru bore at 2.4 inches or something like that with only a 6" faceplate. So I went over to lay eyes on it myself. NOPE. The thru bore was way smaller than 2" (as you know). I only stated...

Tim-- What was the thru hole diameter of your 8" indexer? I have to be able to pass a full 2.000" diameter. That doesn't happen in any indexer I know of until about a 210 mm platter size (equiv to a Haas HRT-210) I bid an auction for a Haas HRT-210 up to $2,300 (with buyer's premium and ta...

I'm not sure if I've picked the correct forum to post this question, so please move it if need be. I have retrofitted a SWI Trak DPM to Centroid ALLIN1DC control and want to add a 4th axis indexer to spline shafts. Here's the twist: I need to be able to pass a 2" diameter shaft thru the indexer...

It is my understanding that you won't get full current unless you are loading at near full thrust. Lots of rapids ot motion reversals. Feel the servos for heat build up.

Centroid will say for liability reasons that you need a step down transformer. So that's what I did at first. But I could not achieve the rapid speeds I had prior to swapping the old Prototrak control with the All In One DC control. Further inspection showed SouthWest Industries was using direct rec...

The initial config included a step down X-former. I could not achieve full rapid speed, so I took it out and am running about 6 volts above the max rated voltage for the servos. I do this at my own risk.

I would very much appreciate you sharing the configuration parameters. Just to be clear, mine is a SJ200, which is one generation older than yours, but it seems to be very similar. Not sure I could directly dump your parameters into mine, but it would certainly be helpful to compare them. I will che...
