Title: Simple drive controller circuit
Post by: jovimon on August 30, 2007, 12:02:38 PM

Hi, everyone. Does anybody know where to get a simple motor drive controller circuit, that works with Mach3 that I can build, to run a little 3 axis router through a PC, 4 step motors, 1.1 amp., 4.1 volts., microstep ?

        Thanks   Jovimon

Hey Whacko, many thanks for your idea, I´ll be studying how to get it through, since I´m not very good designing circuits.

There is a working example in the .pdf document using the L298. It's a reasonably common IC and inexpensive and good for 2A 80V. I used it on a scale model for RND extensively and has good switching characteristics. If you need more help, let me know!

Yep, the giraffe is kinda shy!  :D

OK Wacko, I´m going to re-check it.

Good recommendation,

another combination of that is the l297 & l6203 chip.  Do a search on google for those two and you should come up with some circuits.
here is a good one, http://www.majosoft.com/engraving/html/stepper_driver_board_with_l297_and_L6203.html ,

I have built one and I used the application notes from  ST to create the circuit.  Go to their web site and look at their app notes section for these
two chips.

Thankyou Arnie, I´ll take a look. ;)
