Re: Are The Moon's TSM Integrated Step-Servo Motor Compatible With Acorn?

makes perfect sense. That was my approach too. Get it running first, then figure out what improvements to make.

Best of luck on the project!

Re: Are The Moon's TSM Integrated Step-Servo Motor Compatible With Acorn?

oh weird. That is strange. I guess they are using the coupler as a way to put contact bearings in it too for support. As opposed to having those separate. I imagine as long as its bored out perfectly concentric (or as close as possible) there wouldn't be any issues. I don't like that it uses a setsc...

Re: Are The Moon's TSM Integrated Step-Servo Motor Compatible With Acorn?

They come in two "flavors" - Regular and Enhanced. The regular is 1/800th of a turn resolution and the enhanced is 1/6400 of a turn. Unless you are really really strapped for cash or can get a screaming deal on the regular the enhanced is only about $45 USD more and I think worth it. You c...

Re: Advice on converting a Sharp engine lathe to CNC

Keith, The sharp is a manual lathe with 8ft between centers? That a big boy for a conversion. Just thinking briefly about the conversion, I would compare it to the value proposition of the Haas: Haas is 10K, gets you a slant lathe with linear guides, tool turret, motorized tail stock, full enclosure...

Re: Are The Moon's TSM Integrated Step-Servo Motor Compatible With Acorn?

Based on reading the manual briefly I think they should be compatible. If you were going to go with the integrated step and dir servos I would suggest going for the clearpath SDSK ones from Teknic. There is way more information about them on the forum and online and many folks with successful build,...

Re: Spindle Motor Recommendations

Yes, it seems the analog board option (https://www.teknic.com/files/downloads/ASU_manual.pdf) that Teknic offers for the MC line of integrated servos (made for velocity control rather than positional) will take in a 0-10v signal as well as a direction signal (when high CC when pulled low CCW, I imag...

Re: Spindle Motor Recommendations

Thanks for the quick reply Marty! I will look at those websites!

What is the thought process for VFD three phase AC vs AC servo? just cost/performance?

Re: Spindle Motor Recommendations

And now for a third post (hopefully this stuff will come in handy for someone else one day!) It seems Teknic offers an analog to digital converter board as well: https://www.teknic.com/files/downloads/ASU_manual.pdf About 60 dollars, but interfaces with their motors specifically. I think I would go ...

Re: Spindle Motor Recommendations

Just to double post here: I have been doing research all morning and I stumbled across another clearpath servo on ebay that took me down quite the rabbit hole. I am now also considering going this route: https://www.teknic.com/model-info/CPM-MCVC-N1433A-RLN_Fan/?model_voltage=230VAC1ph It won't spin...

Spindle Motor Recommendations

Hi all! I have been very happy with running my CNC mill these last couple of month and have been cranking out parts I have designed, but the big bottleneck in my mill currently is the spindle motor. From the factory the Precision Mathews PM-728VT comes with a 1hp brushless DC motor for the spindle. ...
