Tormach hasn't been around too long is why but I have seen a few for sale over the years. Theirs a novakon nm-200 and I think a mikini on eBay right now wich are similar. but I sure don't have an extra 10k for one. and I dream of a CNC with an ATC. In other news my 150$ offer has been accepted on the van Norman now i just need a 3/4 ton truck a trailer and a forklift & abought 3 hrs.

If I had to do over again I might take the Tormach over the Novakon. I have a PCNC-770 series 3 for prototyping at work and use the NM-145 at home. I have to say the NM has taught me a lot about how to wire a cnc and cnc maintenance. not because I had spare time though. I had to learn how to trouble shoot and setup the machine because of various failures. Dont get me wrong its a good machine once you work out the bugs but the tormach just works.

The tormach on the other hand has been flawless mechanically and electrically. The issue I have with it is the controller interface. Tormach has a proprietary screen set and its very powerful but I would have designed it a bit differently, it seams not all the buttons you might want are on the same screen :shrug: I guess you can get used to it. Its difficult to go from the standard mach3 screens to the Tormach screens back and forth. I also dont like how they have the screens and options locked out from the factory. If you want to do something with the settings you have to sign a paper basically voiding your warranty then they give you a code to get you into the settings.

New MOSFET's came in. Swapped one out and same problem. Looking online for a motor controller repair service I see that I can get a motor controller for pretty much the same price or less than a repair. It's not the factory motor or controller, so at this point, I don't care. On the hunt now.

Unfortunately the most appealing ones have been just a touch under the max amp rating. The best one was rated for 2.5A and my motor is 2.9A... bummer.

When the switch goes to 'on', the motor goes to max rpm. Doesn't matter where the pot is positioned.

It's a Sherline 4000 series lathe. The motor and controller are not factory. The controller is a home job and the motor is a 1\5 hp Dayton.

Thanks Rainman, but it's actually a Dayton 2M139A.

Riddle me this Batman; Would a typical in home dimmer switch work? I'm thinking something like this: http://www.amazon.com/Leviton-6602-I...productDetails

It's rated for 600W and my motor maxes out at just over 330W. Assuming the dial has the 'click' to turn power off to the motor, I'd be all for using something this simple.

On Granger the motor specs say 10,000-20,000rpm?

I think this would be cheaper than a house dimmer and have a better chance of working.
