You could change controller to an ethernet one like a UC400eth. (Better than USB) .
Get a couple of IDC26 to DB25 cables. Then use your existing parallel board with it on one of the ports and just...

If it's a belted version: Have a look at the pdf manual for the PM25MV mill....

I assume you mean, no pport on pc, and usb connection from pc don't control the board, correct?. In which case:

My guess is that the boards parallel port is the control and the USB is just for 5v...

No.
The vfd 10v is to give power to a manual 3 pin potentiometer. Then the pot dial adjusts that voltage and sends it back into the avi input via the wiper based on where you position the dial....

Either send a pwm signal from a ucbb output- then put this signal into a pwm to analog converter- then that goes into vfd.

Or do what I've done. An idc16 cable from analog port on uc300 into an...

If you find that your max velocity is below what you would like, swap out the 36v for a 48v.
I'd have gone for the DM556:

Depends on what you want to do and the motor spec. Model number not showing anything so double check you have it right.
What are it's dimensions, that may also give us a clue on it.

Personally, I...

Not convinced for the price.

It's all I've got for now. I'll replace it at some point soon.
All switches are NC so if I get a break I'll know about it.

As for 4 core from Igus:...

You have a machine that's running so why not make some custom parts and beef it up!?.
Make some bearing carriers that are 1 inch thick to house 2 AC bearings back to back to replace those...

First off. If JAZZ recommends, you're best off following it.

Secondly. If you're happy with the old Dell and Mach3 then go for it. I use the same combo at present on WinXP and it's been fault...

That's got to be your worst pun yet Dean :whistle: :rolleyes:

If you prefer seperate equipment: UC400eth + 2 of whatever bboards you desire/prefer. 24out/10in
Go all out with the UC300eth Max from cncroom: (uc300+ ub1 + ud1 + license). Around 36out/49in.
If...

It depends on your needs. Work out how many I/O you need then you know your options.
CNCdrive do a deal evry so often where you get a controller, bboard, cables & license in a bundle....

Never send a full machinable drawing to China.
If it's a decent part design.......... They'll steal it!!!.

Even 60Vdc isn't enough to reliably run 34's in my view.
I know I'm talking of a mill with gibs here and routers are looser running, but still., I could not get my 1080oz reliably above 450rpm...

I would go no less than 48v.
48V 800w will do it easily.

Generic 4 axis kits normally come with 2x 36V 350w supplies so the supply I suggest above is plenty :)
(36v is usually dissapointing).

If both vfd's do exactly the same. I'd say the motor is a duffer internally.

I'd give these a go on the ballscrew end.
Needs a bit more research but I've seen them on aliexpress.

Need to do more research but the CL86Y atm.
I'm still pondering about going closed loop later down the line. If this can run in open loop as well (for the time being), then I'll get it right now.

Even with motors of near the same inductance is proven.

Results using 60V on a G0704 sized mill, all driver settings identical, X & Y axis:

I've got a 112mm taper lock and it is weighty.
It's for the 1.8kw servo that's going to be for a mill spindle.
Wouldn't fancy that on a ball screw!!!.
Going to have a go at lightening it with...

I've snapped 3 of those metal 'flexible' couplings so far.
I now use the spider type with no problem at all....

I found that trying to get a decent torque rating with a good low inductance was nigh on imposible in the crappy uk. There's a lot of junk around!!!
I'm using these 4nm (566oz) 3mh ind steppers in...
