Hi,

I emailed them month ago but got no reply.

That is par for the course for XHC...they've got your money...what matter to them if it does not work?

Do you have an idea to solve my problem without replacing the board ?

No, I do not. If XHC can't help you why would you think that I or anyone else can?

or can you give me an exact recommendation for a good 4 or better 5 axis breakout board ?

I have given you some recommendations to research. I personally use an Ethernet SmoothStepper (ESS). Note that the ESS (and UC100, UC300 and UC400 come to that) require a breakout board in addition
to the motion board.

You are confusing a motion board and a breakout board. A motion board converts Machs numeric trajectory data into accurately timed pulse streams. This requires dedicated hardware, in some case a microcontroller
or an FPGA. The XHC board you have has an FPGA. A breakout board takes those pulse streams, usually amplifies them a bit and presents them to the outside world usually in the form of screw terminations.
The breakout board does not have any logic per se, but protects the more expensive and sensitive microcontroller or FPGA from damage because you hooked up the wires wrong. The XHC board you have
bundles both motion controller and breakout board into one.

Other motion controllers like the ESS have separate motion and breakout boards.

If its just the board it might be ok. A solution would still be better.

Good luck. If the manufacturer won't help you then you'll need some luck.

Hey,

one day later and a few things have changed a bit. I mixed up the plugin of the MKX-IV and a configuration file for the MKX-V and now i can reference the 4th axis! Still if i try to move it with jogging the axis it does not respond. So 3 axis work and the 4th is spinning in reference mode. In fact i might need someone who knows how correct the jogging in the configuration or in the plugin. Since i am new to this i am not sure where to begin but it does not seem a big of a deal if i know where to search or correct.

1. I can not speak for the company XHC itself but normally if you are giving a littlebit of support your recommendation goes up and you are getting more sales which matters most of the time

2. Nobody said that XHC can´t help me, they just do not reply. In fact we don´t know if they might be able to or not.

3. Thanks for your recommendations and yes i am confusing the both because i thought it was a synonym. Now i know the difference. If i am not able to fix the plugin or the configuration data i will think about getting one of this ESS.

4. Hopefully the luck is on my side. Since i had some success with the referencing of the 4th axis it should be possible to fix it but i need to learn more about mach 3 configuration to get the jog and control to work again since the driver seem to do its job.

Its a pitty that there is such a bad product documentation and with it even wrong lables on the controler of an original board. The driver of the MKX-IV is working for an MKX-V board and the MKX-V driver leads to a crash of mach 3. The configuration data of the MKX-IV doesnt work but the one of the MKX-V does. Strange but good to know.

Websites i used to get the XHC drivers and configuration data are linked:
https://www.cdxhctech.com/html/edownloads/ --- Old webside of the manufacturer. You will find unorganised drivers and manuals for the cards but no configuration data
https://www.nvcnc.net/xhc-cnc-controller --- Best and well organised website for the XHC controlers, you will find configuration data, drivers and wire diagrams here. Watch out if you controler says MKX-V it still might be a MKX-IV or works with the corresponding drivers ! Look at the wire diagramm and esp. the motor connection pins. Even if your card looks totally different.
https://www.wixhc.cn/de/ --- New manufacturer website with a list of products. Not very helpfull nor does it provide any downloads for the boards or configuration data

Thanks for anyone replying and helping! I will try to keep this updated and add tags so anotherone with similar problems might find this after i solved mine or got help.
