Hi again all.

Next question in my new found CNC quest!

I bought a relatively vanilla flavour Chinese made 6040 machine.
Control box looks like this:



It has an USB controller connected to a Win7 32bit laptop.


PROBLEM:

After installing and configuring Mach3 software (as per manufacturer's instructions), I got this message in the final step of setup:

"Find no XHC NcUsbPod!"

This happens when hitting the E-Stop button in mach3. The message is shown in the STATUS field, like this:




STEPS TAKEN TO RESOLVE PROBLEM:

1. I contacted the supplier, but as expected, it would have been more helpful to contact The Pope in Rome!

2. I searched this forum for "ncusbpod" and read everything I could find.
This lead to a link posted by joeaverage that pointed me to a Chinese supplier website and there I found a different (and newer) version of the NcUsbPod.dll file.
(The website is here: http://www.cdxhctech.com/html/edownloads/220.html)

3. I replaced the old NcUsbPod.dll file with this newer one and voila! Message gone and machine seems to be working. (I only ran one test piece of Gcode, but it seems to function OK for now).

MORE INFO:

I have checked every single setting in Mach3 with the two different .dll files installed.
Everything is exactly the same except the following settings screen:

->Mach3 Main Menu    ->Config    ->Config Plugins    ->NcUsbPod-XHC-Mach3-USB-Motion-Card   ->Config

Here is a screenshot of that settings screen with the original .dll file installed:




And here is the same settings screen with the new .dll installed:



The old NcUsbPod.dll file is 268K big and dated 26 Jan 2015.
The newer one is 420k and dated 15 Jan 2018.

I have not (yet) opened the control box to see what exactly is in there. I guess I can if that info would help.

QUESTION TO THE GROUP:

Was this a good idea to simply replace that file? Can I break my motion controller by doing that?

Any input is greatly appreciated.
Thanks in advance!
Regards
Andre

It won't break anything, but it may not work correctly if it's the wrong plugin. My guess is that it's not the correct plugin, but until you look in the box, you won't know for sure.

Hello I have a xhc mach3 controller for 4 axis but now it dont work properlly.
From a day to another without change anything it simply dont recognize the controller and appears on the mach3 software "Find no XHC NcUsbPod!"
I've tried with my supplier but until now without success by teamviewer, wich makes me believe that it dont have a pc driver problem.
When connect the USB to any computer it dont make any sound recognition and the work led on the controller blinks slowly wich means some problem on the connection or driver.
I already change the cable and weld a new usb hub on the circuit to replace the old one triyng to see if the problem could be on the connecting system but the problem remains.
If there is someone with the same experience or with any solution please help me i'll appreciate.
Thanks
Regards
Joao

Hi Joao,
your experience is not new, many have had that same frustration with that controller.

My advice is throw it away and buy a US or European made controller, there is plenty of info on this forum about the tried and trued manufacturers.
This my not be particularly pleasing advice....no-one wants to have to junk a device they paid good money on....but there comes a time when you
have to admit that buying it was a mistake and move on. Your CNC hobby will not progress properly until you do.

Thanks for your advice Craig.
Even from China that controller is not so cheap, so i thouth that was good, but that frustration persist like 2 months triyng to solve it with them and the answering is very limited.
There is some supplier here in Europe or US that you advices me?

Thanks.
