xhc-mk4 controller

Hello members!
I got 3 axis milling machine with xhc-mk4 USB controller.
It was designed for Mach3 but is it possible to use it with LinuxCNC?

I believe so.

linuxcnc.org/docs/2.7/html/man/man1/xhc-hb04.1.html

Unfortunately XHC-HB04 is a pendant but I mean controller between computer and motors - motion card.

Ah. No.

That is a CNC controller.

LinuxCNC is a CNC controller. They do the same thing, rather than work together.

(Mach3 is also a CNC controller, but when used with one of those it becomes just a fancy GUI for the controller. The reason that they do this is that the more copies of Mach3 they sell the more money they make. Otherwise it makes no sense at all to run a controller from a controller).

Hi,

I have recently switched from same mach3 card to linuxcnc. I would never go back, although it is a very steep learning curve.

sorry it's not compatible with linuxcnc

The Mk-4/4 are not controllers, they are multi axis step pulse generators with some basic IO Attached. They have no interpolation ability or trajectory planning and do not accept gcode so are far from an cnc controller. The firmware on the Mk boards are a cut down version of a more effective product that does have these abilities. A quick google of some of the function calls exposed via the usb version of this device suggests that it could be allot more capable than it is generally assumed to be and I expect a better programmer than I could make it work just fine with Linux cnc.
