Hi Mocha..

Did not blow a motor, just an old driver that was only rated at 35v, and I put 43 into it.. Bought a Gecko g250x to replace it, but seems my luck is running consistently and this driver is dead.. Just waiting for a replacement now...

Why a 250?
Surely a 251 with terminals/heatsink would be a better choice with less risk of it dying due to not installing it correctly?

How do you install one icorrectly?

The G250 needs to be isolated from whatever you bolt it to, and comes with a pin header for cable connections.
The G251 comes bolted to an annodized heatsink which isolates it (hard annodizing is a good insulator), along with screw terminals to make wiring it up easier.

Gecko sell the heatsink seperately for those who want to use the plug and play benefit of the G250, without having to worry about how they're going to isolate the driver.

Hi m_c

I am using a Pentium heatsink and have it isolated with heatsink tape.. The pins are the same gauge as those found in PC's... I have made up a terminal block with shielded cable, heatshrink and the correct connectors (robbed from an old PC).. Its all good..! But I do agree that for an extra few quid, the G251x is a better bet, especially if you dont want to prat around with all those bits and bobs..
