Desktop size steel welded router 3 axis

XHC board wasn't budget £105, yes you correct they as good as plug-in

Yes it is Budget it's just over priced.!!

Still not happy with the speed of X axis. Motor had to be slow down to 1450mm/min.
Z and Y goes above 2000mm/min.
Today I run only ballscrew nut with everything loose and still stalling.
I remember noticed that on dry test (driver - motor) one was stalling at much lower speed.
My motor is 23HS8630B with 1.6mH phase inductance, powered by 24V only, 6 cables (4 used only +A-A+B-B)
I use 4 wires so winding are in series 0 is not in use


I will keep it connected that way do not want to sacrifice torque at low speed, so need more voltage.
Am I correct?

Tom 24V won't even get it out of first gear. but it will depend on what drivers you are using. if you have decent drives running about 50-70V it should fly.

I use DM542, they can handle max 50V, so I can not safely plug in to my big box

Ok well can you try it at 45V and see how it goes

... 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.
