Thanks for offering to help!

The VDF is a FULING INVERTER DZB300 series. Specifically, markings are "DZB312B005.5L2DK". The inverter drives a 3.2 KW spindle motor. If you can, can you pass along a link to the manual? I've looked around and am not certain which manual applies to this model.

Thanks for the mach3 controller bug tip: no pause until I upgrade the controller. Regarding the controller on this machine, what would you recommend upgrading to?

... As far as a link to their web site goes, this is weird but I just went to their website http://www.alphacnc.com/ and it appears to be parked at GoDaddy. Maybe they forgot to pay their domain registration renewal or were hijacked? Or I wonder if they're in the process of going out of business? That sure would explain their failure to respond, etc. Anyway, they did exist, here's their youtube page https://www.youtube.com/channel/UCEb...O5g2yudPzE5jeg

For what it's worth, here's a link to their site as copied by the internet archive: https://web.archive.org/web/20190107.../alphacnc.com/

The specific machine I chose wasn't listed on their web site anyway; it was recommended by the sales person when I told them I needed to work thru metal fast & with good precision. I can share the specification PDF if you're interested. Looks like I might have a 'unique' machine...

This manual should cover your VFD Drive it is the DZB300 series but covers the DZB 200 series also
