Hi, Since one of my last set of drivers let its smoke out, I just took delivery of a new 4-axis driver board from China - OK, I know, but it was cheap like me..... this is the reference to it http://tinyurl.com/yjyasqu
The board is based on Toshiba TB6560AHQ chips and one thing it requires which I haven't come across before is an enable signal for each axis. these are active high. I've trawled the documentation - stepconf mentions 'amplifier enable' but says nothing about what it is, I have found references to 'charge pump' and 'PID enable' but don't really understand what these are.. So, how would I write enable outputs in a hal file so that I get one for each of the 4 axes - would this be an appropriate way of doing things - or would I be better to provide a permanent pullup to +5v from somewhere for each pin, or intercept the parallel port pins and take each to a manual switch to pull up to +5v? The parallel port pinout appears to be 'Xdir, pin1 - Xstep, pin16 - Xenable, pin4 - Ystep, pin14 - Ydir, pin 7 - Yenable, pin17 - Zstep, pin3 - Zdir, pin 6 - Zenable, pin5 - Cstep, pin9 - Cdir, pin8 - Cenable, pin 5 - Spindle motor, pin2' Any help gratefully received... thanks Ian _______________________ Ian W.
