Cheaper drives
 
Does any one know of good axis drives that i could replace or rather use instead of the gecko 203v drives usin nema 34 motors and the pmdx-122 bob board

keling - affordable units (be sure to pick the correct step and current value for your motors)
uirobot - used on a few MechMates already
automation direct
gecko G540 drive - The most affordable solution with the right choices.

Also, you don't need the G203 series drives, others in the gecko family will work.

I have used Leadshine models drives for the last build, and they work like a charm. Probably not the worlds best, but they do the job, and are affordable.

Thanks for the link, Ken. Interestingly, they are located in India.
Anyone tried them out? The drive looks pretty slick.

Browsing through the site, I came across a very nice looking
BOB too. This could be a pretty good option for builders in
this region.

I am already using these on my CNC machine - the surprising fact is the the drives were designed by a fellow Mechmater - Anil - his thread is here

Folks here could also ask for a discount

attached is a picture of the drives on my new machine.

Regards
Irfan

Those caps are needed because he used long and thin wires to connect power to drives :)

Ahhh.... Channel isolation & better PS Zo :)
A thick 12g loudspeaker cable should save the trouble nicely ?

Anil, would you kindly elaborate the protections you put into your drivers?

aniljangra Wed 30 November 2011 02:33

Thanks Ken for your keen interest, basically drivers are protected for current at the outputs making them protected from over-current, miss wiring and short circuits at the output.

So you can only destroy them by connecting the power in reverse (even then the fuse blows) otherwise they are safe to common miss use or miss wiring.
