how to set up my 4th axis with a servo
« on: December 14, 2012, 07:30:01 AM »
I am a bit lost on where to start but I think I have the equipment and electronics to make a with axis im just not sure of how.  Im looking for some advice

so as far my setup goes this is what I have

Bf20l with 3 axis stepper motor control (all works fine)
MD03 motor controller http://www.robot-electronics.co.uk/htm/md03tech.htm
Vertex HV6 rotary table
Electro Craft DC servo motor E240 with encoder HEDS 5540
 My main 3 stepper motors are connected via mach3 using the parallel port and the card which i got for the mill which is this one

Additionally I have an arduino I could use between a driver and parallel port.

Im not sure but Im guessing this is just for stepper motors but I could be wrong

I want to be able to connect my motor and encoder to mach but I missing something.

Either I get another stepper power supply for the board I already have or use the list above.   I could additionally buy a driver for it but then what would I use a separate breakout board for the servo signal or could I just attach it to pins on the parallel cable?



The documentation for my parallel board is unfortunately in German but if you can read German you can find it on this page

I have suspect that if I get a driver that can accept step and direction for a dc servo motor it could work.  Perhaps someone would know of a driver that might work with my setup for the dc servo motor and encoder?

I know that might look a bit of a mess but Im keen to come up with something.
