Good Day All.
This is not directly PicAxe related as such. so I hope I don't get shot down for posting this here.
Now that I am making more and more prototype pcbs with my on going projects it's taking a long time and is getting real boaring dilling all the hole by hand.
So I am looking at building myself a little cnc rig to drill holes in prototype pcbs.
I am going to need 3 axis and spindle control.
The rig it's self I am going to be building out of old broken printers and scanners.
The stepper motors I have collected so far are a mix of unipolar to bipolar, I don't know witch would be best suited for my rig.
I would like to be able to control the rig via my computers printer port, I am looking at using the Mach3 software.
I would be looking at building my own driver board, but as I have not worked with stepper motors before I am in the deep end.
If possible I would like to build a driver board that would support both unipolar and bipolar stepper motors, If having support for both is not possible then I will build a board for used with the best suited stepper motor for the job.
Could anyone please point me the way to find some Circuit Diagrams that will be able to do what I am after.
Can anyone please tell me if I can leave the printer port inputs and outputs free floating or if they have to be pulled to ground or vcc?
I have been looking at some of the designs over at www.pminmo.com but I would like to know if anyone has a better suited design.
Here is a list of a few of the stepper motors I have collected.
4 Wire Stepper Motors
Mitsumi: M35SP-7T.
Mitsumi: M42SP-6NK.
Epson: EM-289.
Epson: EM-293.
Minebea Electronics: PM35S-048-FEE6.
5/6 Wire Stepper Motors
Minebea Electronics: PN55L-048-HPI1.
Minebea Electronics: PM35L-048-HPC8.
Unknow Make / Model.
Thanks for your time.
Best Regards.
