Hi All,
I'm having major problems trying to get my new AXBB-E controller to run the spindle. My router was working fine with a chinese controller (the MK4-V from cdxhctech) but I need to use probing g-codes which that controller doesn't support, so I'm trying to upgrade the controller to the CNCDrive AXBB-E, and it's not going well. I read as much as I could find and thought I had it hooked up to work - the same as the authors conclusion in this thread https://www.cnczone.com/forums/spind...nyang-vfd.html
But the spindle will only turn on to about 100rpm or so, and the controller analogue voltage won't go over 3.8v (I have removed the jumper to set it to 10V range), while the inverter is looking for 10V
I started checking voltages everywhere and got a shock (not literally) when I found +24V on the controller forward output control pin - so I unplugged everything and checked the voltage on the Inverter - see pic below - surely that's not normal?
I think that 24V on the inverter forward input has damaged my controller board, the controller output pin that I had originally connected to the inverter forward input to no longer works.

Thoughts anyone - is this normal, or perhaps I did something bad while rewiring for the new controller and now my inverter is busted - and maybe my controller too?
thanks
Kevin.
