Based on the specs, it would appear to be based on the same Allegro chip that the Xylotex is.

doesnt appear to have the heatsinks on this one? or mabe has some chip heatsinks inline... The curretn and max volts seem to be same, as well as microstepping etc...

I bought 3 of the sop1's on impulse....Too boring imho.....uneventful wiring and power up...worked straight away without any issues. Total cost £60 and used 3 0.65A 4.7V 4 wire Bipolar steppers from a skip (dumpster) one thing to watch for is loose solder on the PCB (unclean...rings bell) I took a picture at 10x with my microscope and it's an Allegro A3977SLPT rated at 2.5A.....how do they do it in something so small :shrug: Personally I'd never have all my axis on one card (unless it was the cheap 2 axis and I had 2 of em for my lathe ) one blows it's all fubar! I'll post back if I manage to break em :lol:

I hope nothing.....I bought one to replace my Xylotex board.....It went out on me and I only bought it in May....the Z went crazy....

Maybee this is a good board for us in Europe? Since we can`t order from Xylotex beacuse their boards not are RoHS complaint...

it can only handle only up to 30v 2.5a

it can only handle only up to 30v 2.5a

But Xylotex board are also rated to 2,5 A. And the Xylotex board is rated to 35v, 5v volts more than stepmaster. But will there be a problem using the NEMA 23 269oz stepper motors on the stepmasterboard?

I have the Xylotex and 4 - 434oz 2.8a motors I run its vref at 3.5 and after emailing and reading EVERYTHING on the Zylotex site all papers etc etc I found that the xylotex motors both the 269 and the 425 are 2.8amp and run fine on the 3 and 4 axis boards! I ran my other motors on it also no problem.

SO the assumption (watch out for assumptions) is that this board should have no problem at the 2.5a rating and run those 269oz motors.

P.S. Xylotex says to run their board at 30v and not to exceed soooo that leads me to believe that tolerances are same and marketing is different.

Ok well I live in the USA I am fairly new to diy cnc. I bought a 3 axis board and have a cnc router with 118 oz bi-polar steppers. I need a power supply. Is the xylotex power supply and fan for $50 the best buy? I also have 3 wire limit switches installed on each axis how do I wire them up?

Personally I recommend a friend in the US to send it as a gift Hell if they wont allow a little non ROHS stuff in they can stop dumping nuclear waste in the sea :lol:

[jfc11]

they are not ROHS either
