I have an ethernet Duet2 controller on my Ooznest Workbee machine that so far I am pretty happy with given I am on a tight budget. Now I would like to dynamically display in mm the position each of my axis are as the machine goes about it's business. I can plug another display on my PC for this. I don't believe I have a RS422 signal on my controller. Would I need to think of a separate way of doing this? Like linear encoders? I would like to be able to zero the work without a touch prove.
