Seeking advice about stepper drivers and power choices

I did try to kill a DS1044 a while back, i failed! Even reversing supply polarity will not kill them, miswired motor will not kill them, detaching the motor while running did not kill them, i ran out of ideas!
Keep in mind you do need a small USB device to program them, so do order that too, it was 28 Euro in Germany.
Without it the drives will be stuck at 1A or 2A for bigger ones, and 1/4 microstepping.
Disclaimer:
I have no affiliation with LAM Technologies, although i think it's about time they send me some more advanced drives to test!
DS10nn series have a Boost feature that RodW uses to drop the current at speed keeping the motors cool while having plenty of torque while accelerating, i used the same feature in the opposite way, namely raising the current when skipping steps are detected. This uses encoders on stepper motors for feedback wired directly to a Mesa board, so the loop and full control is done by LinuxCNC.

Thank you Rod, i was trying to explain a feature that LAM drives have as standard and ways to use it, but as always, you are much better at explaining stuff.

You can still use the Geckos, 251 should have no divider by 10 if i remember correctly, i hated that in G540.
I also hated that in their servo drives but i yanked them out !
Otherwise Geckos are quite good, and a bit expensive for what you get.
But in full step mode, they were the quietest by far, so that counts for something.

Looks neat !
