Huanyang VFD control plugin for Mach3, USB RS-485

[JayPunchbuggy]

Hi,

I reciently picked up one of those Chinese 6040 routers you see on eBay. Worked right out of the box, very pleased! But didn't like the manual control of the spindle... Eventually, I found this gem:


mach3-plugin-for-huanyang-vfd/


I got a cheap RS-232 to RS-485 converter (about £3 from ebay) and wired it up with an old cut up usb cable (connected the shield only at the converter end. Installed the plugin and it worked! I can set the spindle speed in Mach3 and get a readout of what the actual speed is. The instructions on website are excelent, so I won't bother re-writing them here.


As I understand it, I can also add a custom readout to the Mach3 screen to show the current current being drawn by the spindle.

One gotch to look out for: Make sure the the Huanyang VFD's interface board board has the transevier populated. U4 I think. Mine did, so I was in luck and didn't have to solder one on.

Hope this helps someone out there.


Cheers,
-Jay
