Those messages are normal for the first time you home a new installation. Just answer "Y" to accept the new home position.

If you continue to get "home differs by __ counts" warning messages after you accept it the first time, then either your home switches are inconsistent (sticking or moving ...

The CAPBRDHI rectifier is designed for split phase, not three phase.

Centroid has a DIOCAP3P rectifier for 3-phase input; but if you use that, with 240VAC in, then you will get ca. 340VDC out: not at all appropriate for your motors.

CAPBRDLO with the 0 and 109 taps is your best bet, if you don't ...

Since you will probably never set up the machine to home Z in the minus direction, you could just go to the Machine Configuration -> Motor Parameters table, and change the Z minus home input from 5 (or 6?) to zero.

Leave the non-zero switch input number in place as the minus limit; just zero out ...

First some vocabulary:

Machine Home (a.k.a. Machine Zero) should be where you home the machine to every day. It should be the same place every day. That is where your software travel limits are measured from.

Part Zero (a.k.a. work zero, WCS offset, fixture offset, G54-G59) is the zero point that ...

You might consider soldering lead wires to the PLCADD1616 board where the relay coil used to connect; and then installing somewhere nearby an external solid-state relay that can be controlled with 5VDC, to switch your load.

It is hard to say without knowing anything at all about your wiring; your control; or your configuration.

Maybe if you posted a report and described how you have wired the drives to the Centroid control unit (guessing an Oak?), then you would get some meaningful responses.

Maybe you have the ...

That sounds like CNC12 thinks a probe or tool setter is tripped.

Remind us: do you have a probe and/or a tool setter? What type? Is it plugged into the control? Is it in a tripped condition?

There is no provision for applying different amounts of backlash compensation depending on how the axis stops and reverses.

The only resolution available to you is to reduce the actual mechanical backlash, and also reduce any stick-slip tendency, so that you need less backlash compensation in all ...

I assume the encoders in your picture are for the electronic handwheels.

The presence of the DS8830N chip indicates it has a differential line driver output, which is what you want. The supply should be 5VDC (not 24VDC!), which would be supplied by the Allin1DC encoder plugs.

If you use the "0" tap and the "109" tap you should be okay. That appears to be what the previous control did.

You will probably get closer to 115V out of the "109" tap, since you are probably putting 240V or more into the nominal 230V primary taps.
