USB/Ethernet controller for Mach3/4 advice

[JAZZCNC]

I will most probably go with the CSMIO/IP-A.

IP-A is perfect control and very easy to do this using the encoder index pulse. See manual how to do it.

And an input called 'Zero clamp' I have no idea what it is for.

Are these brushed DC servo's.? if so then be careful as the encoders are probably single ended and not differential which the IP-A requires.

Is it safe to use only one switch on each axis side for both soft limit and home?

Soft limits doesn't use switches it's exactly that limits set in software so no switches involved. It's safe to use shared limit and home switches if your stuck for room or inputs but with so many i/o why.?

They are brushless AC servos with differential encoders.

Now I'm not sure which 'operation mode' will it be with the analog control. Where it goes the Vref+ and Vref- from the controller? I attach the config chapter of the drive manual.

Torque mode is what you'd probably use and you'd use pins 1 & 8

hi
I contacted star tech about using one of their usb to parallel adapters, I stated that it was to be used with a cnc machine and mach3 software the sales person went and had a word with their technical department and said for use with a cnc they recommend the ICUSB2321284 usb to parallel and serial converter is anyone also using this converter?

I have not heard of any usb to parallel adapter that will work with Mach3 and a cnc machine. You have to get an usb or ethernet cnc controller, a PCI parallel card or an old computer with a parallel port. Some newer computers may not have a parallel port connector at the back but provide it inside on the motherboard and you can connect via an adapter.

Something's telling me that I need to use the speed input, but will see when I'll have the controller.

Thanks a lot for your help.
