Desktop size steel welded router 3 axis

I do not recommend Chinese sensors, few of them failed before I finish calibration (one I managed to smash)
I tried 2mm and 4mm seems to be no difference in accuracy. I wanted to improve accuracy for homing but there is no difference with decent omron mechanical switch - wasted money in my case.
I use Z18 and Z20 pulley which gives 0.8 gear ratio. Machine mend to mill alloy, so do not need super speed 1400mm/min at 64 microsteps. Might change setting when start cutting P6 alloy or similar.
I use Digital drivers DM 542 - thanks Jazz for advise, much better, smooth, quiet run.
I am not happy with this usb card

I lost soft limit function over the night without touching anything - was ok, and now machine is in limit but message says that is out - you can not win.
Homing was ok, now every axis trigger home and have to be reset to do another axis till all done.
Reset has to be pressed twice, so often. I think to come back to DOB 25 and LPT port.

Tom I've fitted couple hundred Chinese Prox switches and had probably less than 12 faulty ones. At just over £1 each they cannot be beaten by any Switch for the money. Don't use Omron but I'm pretty sure they will be quite bit more than £1. . . .You wasn't trying to use them with 5V was you.?

Regards Controller you get what you pay for I'm afraid and I cringe when I see people say they bought cheap chinese controller. EVERY motion controller for Mach is only as good the Plugin that runs it and NO Chinese controller is supported by Artsoft so your onto loser from the start.
But can tell you decent Motion controller has the same if not more impact than going from Analog to Digiital drives. Combine the two and you have Huge improvement of PP and Analog.

Cslabs are my first choice but you won't go wrong with Pokeys 57CNC or UC300/UC100 if on budget.

Jazz I might be unlucky, 2 sensors were blinking close to target (made, not made state) all powered by 24V.
XHC board wasn't budget £105, yes you correct they as good as plug-in, second one only works - sort off.

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
