Huanyang VFD control plugin for Mach3, USB RS-485

[JayPunchbuggy]

If it is interference then what can I do to fix the problem??

You could try:
1) make sure the shield of the RS485 cable is actually earthed by the checking the continuity of it to the PCs chassis
2) Ensure that the RS485 cable is not run near sources of interference, like the spindle cable. Especially avoid running the RS485 cable parallel to any other of these cables.
3) try a lower baud rate
4) reposition the USB to RS485 converter

Hope this helps! To suggest more, a photo or more detailed description of your wiring would be useful.

Cheers,
Jay

Just a quick update on this as I have gone over everything again & also tried the converter that Jay had bought & uses.
Had all sorts of different messages depending if it was via the serial to 485 connection or the usb connection.
it will run run on the plugin on this thread but stops at some stage. On the original mach3 plug in that is available via the mach forum it starts the spindle, cuts the job, returns to zero but does not stop the spindle.
Actually got some work to do that I get paid for just now so this is going to have to wait. Just as well I haven't been asked for any work that I would need to use the router for lol.
