best stepper driver???????

[NB70]

I use the Motion Control Products MSD542 ones, I think they are made by Leadshine in China (M542 OEM model) and sold under different brandnames

They are not the same driver, close but not the same.
As allways in china you will find copies of everything.
Leadshine are the largest manufacture of stepper drivers in china, and there are lots of copies of their drivers, some good, some not.
by the way i will match Arc euro trade prices as long as i have them in stock.
You may also want to try our PM752 for higher current motors, it is a very good driver and goes all the way up to 70V.
