Hi,
thanks for the reply, it really is hard work just looking through the manuals especially as i'm new to this
Looks like my only hope is the A/B pulse which the manual says is "A-phase and B-phase signals with 90°phase difference", does not say what voltage
This did not really mean anything to me, looking on the internet it seems to be a "table" of two values (A and B) that you move through forwards or backwards.. is it really that simple?
What comes to mind is converting step/direction to A/B via some simple TTL circuit (or a small microcontroller), does that sound possible?
I will investigate SmoothStepper, not found much info yet, I really wanted to get things going as cheaply as possible until I prove I can work with the Mitsubishi drives at all, maybe just get something working at a slow feed rate then progress from that
The other thing I found was something called "CL Mode" which it says is "quadrature" for working with MACNC CL10, was this an old feature with hard coded output for one specific mill?
thanks
Kevin
