Encoders for each axis

[simjim33]

Please forgive this very lazy question.
I m still working nights and I have two full 12 hour nights to go yet.
I wonder how the following could be done with masso.
the relevant part to this question is at 17:40 ish.
I really like the idea of individual encoders.
Plus I m just about to rebuild my machine. With my G2.
Please have a look.

Just to save everyone 30 minutes of video watching, the question is:

Using his Masso G3, how can he use 3 separate, dedicated MPG handwheels (one for each axis) instead of having one MPG and an axis selector switch?

I did say the idea was at 17:40.
its also a G2 but. That s not the question.
I should think it would be a case of wiring into the mpg input set. Which puts out voltage. If I remember right. Each axis has its own channel. Doesn t it?

The issue is that Masso has only one encoder input set (MPG A/B) with several additional digital inputs to select the relevant axis.

This could be done using a small micro-controller which takes the encoder input sets (pair of signals) and performs a bit of processing and sends it to Masso while selecting the appropriate axis.

The micro-controller would need to keep track of each hand wheel to determine direction (two consecutive pulses on the same signal indicates a direction reversal) and then call a subroutine to select appropriate axis, and send the step pulse.

A lot like the unit shown in the video.
I was under the impression that the normal pendant connection had a common v+ and the selector diverted the AB to a pin for signal.

the micro controller will work though. It just finding the right one. The code for it. Then if the pendant input can t be used. How to wire it up.
