Anyone has any experiense with these.. I can get a 4.2Amp 50v Microstepping driver for 39 pounds sterling. That's about 70 dollars a piece.

I have bought from that company before and it was a pleasure to do business with them. (Their one sales guy is from my country and speaks my language :-)). I have no experience of that particular driver though.
There are some comments about that drive on the CNCzone forum - some say the 4.2 Amp is "peak" and should drive no more than a 3 Amp motor. |

The it should be good enough to drive the steppers on the mechmate... as they only take max 2 amps per phase using the vexta motors....
And the Motionking dows only 2.7Amps per phase...
I think I'm going to try them out, I can always resell them If I don't think they are good enough... |

Kim,
I know that most money-trees became extinct years ago, but I would suggent that if you can, find the funds to buy Orient Motor steppers and Gecko stepper drivers. They've been proven to work all day every day without fail (barring malicious meddling). Having proven components will make your life so much easier. You'll be able to get help from a number of other users who have parts identical to yours. In my experience, that alone is worth the cost of the Oriental Motor steppers and the Gecko stepper drivers. |

Mike, your perspective is influenced by the fact that you are near to Geckodrives and an excellent Oriental Motor distribution center. Guys like Kim and I don't have those luxuries and we tend to shop around and experiment a lot - sometimes we are lucky, sometimes not. We do this being fully aware of the risks in not following conventional wisdom.
I lost $800 on a USA shipment that did not arrive. But I have friends and family regularly commuting from the UK and thus shopping at Motion Control Products is a reliable option for me (and probably Kim as well). |

Well, I tried to order the MSD542 Microstepping Driver (4.2A 50V) at £28.50 (US$60) however they wanted £60(US$120) for shipping across the north sea... Given the website said the cost would be £30 and I was quoted US$30 for shipping of 4 gecko drivers from the US, this is ridiculous. It brings the cost pr. driver up to $90, by then I'd rather spend a hundred dollars more for four gecko 201s because they are far better value IMHO. |
