Hi All,
I hope the collective minds here can hopefully solve this problem. Below is a picture of a Chinese MPG I bought - wasn't a lot in cost terms but even if its crappy it should work - Right?
The Chinese instructions are even worse than useless and i'm pretty sure the 'Technical Support' the company offers is someone reading their own instructions and not knowing
what the product does!
It says it is a ModbuS controller and will connect to Mach3 via a USB port connection. They recommend using MyDrivers to update the drive programme - useful if you have a mobile phone.
knob all use for this application! The unit powers on via the USB plug, function lights flash, move to different axis when selected and the pulse LED illuminates when the wheel is rotated
but as for connecting to Mach3 - Nada ! ! ! I tried to understand the Mach3 ModbuS instructions but ended up even more confused - and they are in English!
Anyone ever used one of these, or have the faintest clue on how to get them talking to Mach3 - I'd be very grateful.
Looking inside - because i'm curious - the USB connects to aRS232 plug having 4 wires that fix to board - these are lablled G, U+, U- & +5. The encoder handwheel has a similar
4 wire connection to the pcb, these are labelled B, A, G & +5. That may be some help - I don't know? It'd be a shame to bin it as its 'actually' quite well made !
