I also purchased a 1212 mach3 machine. XHC motion controller plus XHC pendant, 2.2kw spindle with Fuling DZB280 inverter - plus a few extra items.
Overall the machine seems to be well built and solid.
The issues I've had so far -
when I 1st got the machine a month ago the moment I tried to over ride the spindle speed it would go to full power, this lasted for a couple of days then all of a sudden the spindle does not go to full rpm, goes no faster than 140Hz, normally between 40 & 100Hz.
I did ask Omni for help but it's very basic, such as a screen shot or the most basic settings for the VFD - to be fair I have been sending a bit of info as I tried several installs over 2 new pcs, same problem persists.
Im 9 hours behind china so I expect delays.
The machine came with no manuals or backup settings.
I did get the feeling that Omni seemed hesitant to send me all their docs relating to setting up this machine.
I still have to resolve this with them before I can use this machine.
The other problem was the pendant, you'd think that XHC products would be compatible, nope, even the fixed buttons such as home.....dont do anything except send z into orbit to the limits.In fact several buttons do this.
not wishing to damage the machine I just left the pendant on the workbench.
I have done some research on other people with the 1212 and 2 in particular had the same problem with the spindle as I have now.
Other than not being able to solve the issue and actually use the cnc I hope Omni will do their best with customer support and help me get it fixed before I rip all the control system out and install something else.
Riding on this will be an order for a much bigger machine so let's see.
Other than the spindle issue, the pendant and lack of documentation it was a pretty smooth transaction dealing with omni; the product is solid and well built. well packed and delivered in a timely manner (door to door, all I had to pay for was duty and doc handling).
Next time don't worry about guangxi, don't quote 10 days prep before shipment when you really mean more than a month ;-)
....now help me with my spindle....please.
