Last time i was on allegro's web site they didn't have the 7052 listed for sample, may be able to get some if you contact a supplier directly. I ordered some more 7051 samples awhile ago and haven't recieved them as yet.

Phil how would you compare the 3977 series to the 705# series? I am currently debaiting on working on a design for the 7051 or just going with what you've already done with the 3977? Kinda of all on the back burner right now, but i will be getting to it when i have a little less work load.

Dave,
This isn't done, just showing you wre I'm at.

The 3977 is a bipolar driver the SLA7051-2 are unipolar. The SLA's are much easier to solder for the DIY'er. 3977 can do microstepping as well as the 52, but not the 51.

SLA7052 microsteps? Look again.

Dave,
Please reread what I said "The SLA's are much easier to solder for the DIY'er. 3977 can do microstepping as well as the 52"..... "but not the 51" To add, the 51 will only do full or half.

The sla706x does microstepping. The have too many part numbers, so it's easy to get them mixed up.

SLA7052M does NOT microstep.

Dave,
You correct, I mean't 62. My bad.

I am not sure how to marry the chopper driver you have with the 5804 board. I took the real easy to build 3 axis 5804 driver board and added a 4th axis to it. It works fine for driving the motors no load, but I don't dare load them until the chopper circuit is in place. I am not very knowledgeable about electronics and I must confess, some of the nomenclature escapes me. Is there any possibility you could direct me to a site that would explane what the difference between a vdd, ext 5, grd, v grd, grd with a flat line, grnd with an x? Also, on the chopper schematic, is this for 1 axis or 3? It looks like this circuit is simply placed between the motor center taps and the higher voltage power supply. Please be patient, I don't know what i don't know.
