Nice job ! This is exactly what i was looking for. I know thisnis an old thread, but i found it while searching for microstepping info, and i happen to have a bunch of salvaged a3952sw's i want to...

Your attachement worked fine. Thanks for the diagram, looks like you spent abit of time on it, nice job. I ran into the same thing, finding a cheap vexta drive(s) after hours of working on a...

Well I programmed the atmega chip and ran the sequence, with not much luck, but a brief jerk here and there from the motor.

I ran across a very usefull artical though, I've attached it below. I...

Nice layout ! It's actually identical to what I have on my Bench soldered up to try. Don't forget Diodes ! I was going to use 10, but then I realized I was doubling up, (what I think doesn't usually...

one a 10 wire or a 5 wire (Penta configuration) each wire is the end of one coil and the start of the next coil (or phase). Picture half of an h-bridge connected to each coil and energized either one...

I have the same motors and am trying to build a driver. I have printed off alot of docs and also bought 2 working drivers to try and get the idea. I've posted the info on this thread if it's of any...

Here's a file on tuning that a gentleman sent me a long time ago, he may still be watching this thread !

You may also want to go on gecko's website and download the documentation on their 320...

I havn't built an elm drive yet. I was unable to find the components when I first started. Then I ended up buying gecko's due to time restrictions. The Geckos are amazing devices, and the tech...

Looks great. Glad to see it's single sided. If you Wouldn't you mind posting the SCH and BRD file so I can print one from eagle that would be great. If you are talking about motor vibration (like...

ELECAPA:

I'd like to have a look at your PCB ! That'd be great, Thanks !!
Which version of SMC is it for ?

The Drive I posted is for penta drive.

The CSD Board:

1 pc PMM8714 - 5 phase driver IC
2 pc MP6901 - Power Transistor Module
(3 used on one , 2 used on other)
1 pc MB3759 - Switching regulator controller
1 pc 5c114e - No idea...

Here's a datasheet from sanken, I think that this one is for a 5-phase stepper wired in a star configuration, not in a penta configuration. A 10 wire stepper can be wired either way. Either as a star...

The controller I opened up (csd5707) used a 5-phase controller Chip PMM8714. Datasheet attached. There is also a schematic in the datasheet. I will scan the board and list the other two chips (driver...

The 5114 is a controller from oriental motor. I bought it on ebay for about $60 US. I had planned on building my own after opening up a CSD5707 controller because it seemed quite simple with one...

Lehung, I have found a great deal of info on 5-phase stepper motors from the oriental motor website, It appears as though all of there 5 phase motors are in the penta configuration. Also there is a...

I have a few small servo's I'm trying to use with Chan's Servo controller. They are less than 3A so I was hoping to use an lm18200 or l298 ic. I'm not any good with ASM and can't figure out if I need...

I have been following this thread for quite some time, and would just like to thank everyone for there efforts. I had wanted to use the higher power servos with the original UHU design, but didn't...
