Myford 7, 3 phase motor other CNC questions.

thanks for sharing this JohnHaine; very much enjoyed reading it.


Jconway651 I have nothing much useful to add; other than keep the thread posted with whatever you decide.

F*ck it, Im way out my depth here but I have seen one of these cheap huanyang vfd's used to power a 3 phase motor.. You would have to read up on whether its a suitable application for you but may save you some money. Im not sure if it would be any use.... I think there are some ways of controlling the speed via mach aswell.

John Haine: Those are some useful pics, my setup will be similar im hoping.
Im assuming you were talking about ArcEurotrade? Is that where you got the ballscrews? They dont have them in there catalogue or online anymore it seems.
The leadscrew on my myford was bent when i got it so i will be going to ballscrews on both axis straight away.
Ive seen the cncyourmyford youtube videos and was quite impressed, although im assuming for his screw cutting he has spindle driven by stepper motor, like in Tony Jeffree's where he has an electronic division master.

Kingcreaky: Im sure this is similar to the inverter ive ordered, and im not to pannicked about the initial wiring and getting it running. However im sure the process of controlling spindle speed through mach will confuse me plenty.

No, if you ordered same as you said earlier you have a Jaguar drive, quite a good brand actually. Have you ordered a breakout board etc. yet ?

Na i havent ordered a breakout board yet, was waiting for it all to arrive before ordering anything else.
Im not really sure what i need to be buying in terms of the breakout board.
I had planned to just get the motor fitted and working so i can continue to use lathe whilst i buy other bits ill need.
