... will post results with 41.5V, that what I've got from torus trafo 2x30V 2x7A, after rectification voltage went up nicely.
Waiting for GBU805 - Bridge Rectifier 8A 600V and capacitors.

Tom like I told you in PM you sent me.!! Voltage makes big difference to speed but even more so with Series wired motors. You'll see improvement with 42V but if you want real improvement then buy some 8 wire motors and wire them parallel. With series wound motors you'll need much more than 42v to get decent speed.

Volts make prizes.!!! . . . . Nice looking machine Tom and very well made . .

Tom it looks like you could increase the acel settings. Have you thought about putting a W.C spindle on it?

Nice machine.

Nice build Tom

Much better now.

Looking at your control box picture in post#66 the stepper motor cables are very close to the toroid - seems to run OK without load and without spindle running but one to watch if it glitches ?

Picture 66 shows different control box - 7A biger machine and was unfinished - cable runs on other side and all are screened and grounded to the plate. Inverter is outside with built in emf.

Nice machine.

Waiting for 48V PSU and will try to bring voltage to 45V and tune again.
I had one 1.5 Kw fi 60mm, but was leaking so had to send it back.
2.2kW is way too big.
See on design:

Be careful Tom because these drives don't tolerate much over 52V Spike so if your Input voltage varies very easy to peak above 50V.
Certainly don't go above 45V.
