AXBB-E any opinions?

[n0f8r]

I couldn't run my VFD from the isolated outputs due to earthing issues. Looking at the manual it seemed to imply that the NI outputs were 0...5V (although one of the examples half contradicted this) - my VFD has something like 16V on the inputs when not pulled down and I didn't want to risk blowing the AXBB-E.

Ok - thanks - looking at getting one of these since my current chinese controller does random shit (like sending the gantry in random directions at full rapid speed) when I try to use Mach3 probe wizard routines from ProbeIt or ProbeWizard - and the ProbeIt guy says the CNCDrive controllers work...

Bit confused though - shouldn't an opto-isoloated output from the AXBB help avoid grounding issues?

[edit] - I still haven't really got my head around ground loops - but I suppose it depends on how you're powering those outputs and the VFD, and I guess the opto-isolation is only between those outputs and the Ethernet inputs from the computer

so I guess I'll just try it and hope for the best - I'd guess my current controller has the same kind of direction output feeding into my VFD, so hopefully that means I don't have the same grounding issue.
