metric thread pitch to SAE question

I have a 2.5mm pitch ballscrew and I need to set up the overall turns ratio in the wizard. How do I set up a units equation to convert a metric screw pitch to one in inches? I have a 20 tooth gear on my motor belted to a 50 tooth gear on my ballscrew. That gives me a 2.5:1 gear ratio (50/20). So my ...

Re: Plasma Version of CNC12 Wish list

Any chance a second tool like a scribe can be added along side the torch? Scribing out hole locations or part numbers before the plasma cutting operation would be a nice addition.

Re: Has anyone found a rotary encoder rated for high rpm?

Quantum Devices QM35 is one option. It is a modular, so you would also have to design a precise mount that can handle high RPM. Thank you, I'll look into those. I sent them a message about their rpm ratings and output signal to clear up some of my understandings. Have you used these on a Centroid b...

Re: Has anyone found a rotary encoder rated for high rpm?

That would be pretty slick if that's all you needed to trick acorn into thinking 1:2 = 1:1.

Would that work, for example telling acorn I have a 1000 line encoder when there is actually a 1:2 ratio 2000 line encoder installed?

Has anyone found a rotary encoder rated for high rpm?

I've been looking around for an encoder to use on my mill that has an approximate max spindle rpm of 8800 rpm. I've looked at the ebay Omron encoders and it appears they are rated at 6000 rpm, what have you guys used on your mill spindles? I've mostly been searching on ebay for cheap import or used ...

Re: Dyn4 wiring qeuestion

Well..... I got busy and my project has just set for awhile lol. Coming here to motivate myself and refresh my memory on troubleshooting details again now. You may have seen it already but there was a couple topics about the dmm/dyn4 servo combo troubleshooting use as a spindle drive, I think these ...

Re: Dyn4 wiring qeuestion

Thanks, Sean! I'll give that some thought. After I actually read the DYN4 manual the wiring process sounded a little less risky. My game plan is kinda what you mentioned, one circuit with a 5v supply for forward and reverse and one circuit with a 24v supply for the enable using the diagrams in the m...

Do you guys think there will ever be a plasma version of CNC 12?

I was just watching the new CNC 12 beta video, they added a router specific mode to the program which is pretty neat. That made me wonder if adding a CNC plasma mode is something Centroid is thinking of developing in the future?

Re: Dyn4 wiring qeuestion

Thanks Marty, ya that was the diagram I was looking at. Can't be that difficult to get wired if other guys have done it I can probably find out how to.

I'll post up a wireing diagram when I do.

Dyn4 wiring qeuestion

I know you said not to Marty but I couldn't resist, I bought a DMM servo for my acorn retrofit spindle motor. The schematic I received from DMM says to wire it as a spindle drive I'll connect into H5 and H8, except there is no H5 on my board. I'm assuming from this schematic from DMM and current sch...
