I thought VR5 had the option to use legacy machines, or does it require the later EEPROM?

Just had a quick look, and it looks like you'll need to configure the machine settings once you've selected the Triac Denstep option. By default, most of the options are not enabled, so you'll need to enable everything that's applicable.

I'm converting mine to Dynomotion's KMotionCNC. As it stands, I need to finish wiring in the tool changer solenoids/sensors, write the required code to make it work, and then do something about making a new control panel. There is a thread on here about it, but I've had a couple other jobs I had to get done, so it's not been updated for a couple weeks.
I'd only be looking for some beer tokens for the old bits. If nobody wants the bits by the time I get the machine fully running, they'll be going in the bin, as I'm trying to avoid gathering piles of obsolete parts.
