Denford Triac VMC with ATC Conversion / Fix

[Chaz]

Can I double check something, for the 0-10V Analog input, this shows using 1 and 14 for the first axis. On the pic below, the left hand side is the wiring of the drivers.

Is VRef- 0Volt or something else?
I assume VRef+ is the 'up to 10V'?

Are my red lines below correct to show how they should join?

Ok well kind of right but your needing ANALOG +/-10V OUTPUTS for the Channel(axis) your using.! . . . It's not 0-10V ANALOG INPUTS they are very different things.!!

I realise you probably know this but it's these little details and wrong INFO back to us here that can get confusing and you in BIG trouble if we do and your letting out Magic smoke.!

Vref - = Negative Voltage ie: -5v = right direction at half Motor rpm
Vref + = Positive Voltage ie: +5v = Left direction at half Motor Rpm

Manual will show you which pins are for Negatve and Positive for Each Channel(axis). Careful you don't Mixup the GND because the Channel GND's are different to Analog input GND's on same connector.!

OK, have some success. Long story ...... dont trust things till you have opened the connector and verified each pin.

Argh the old pin shuffle gotcha trick.!! . . . Got me too many times. My prefered way of converting is to rip the guts out and start again. It's often quicker than chasing dodgy wiring and connectors.!

Really liking the progress on this. Great job. If you decide to sell it make sure there are crowd control barriers in place.

I have 2 Triac VMC's and a Cyclone and all are great machines. i2i is the man if you have any questions on the Triac. Its quite possible he may have designed them lol.

Thanks. Those your vids? Watched a few of them before and after buying my Triac.

So, had movement last night. Now I have a machine determined to go max X Y Z + in all directions and I cant get it to come back from that. I cant engage soft limits on Mach 3, says I am no longer able to use that as I have gone past the extreme limits. If I hold in the axis override button on the Denford, it just keeps going more + in all directions. When I try and jog to -, eventually I get a ePid fault.

Argh.

Sorry, its gone to - on all directions. Trying to move to +. For reference, I am not using any limits wired to the CSLabs yet, its still using wired through its normal E Stop etc for max overlimit etc.
