I ordered a replacement off pololu. It's got fewer steps and is slightly longer but should work. Probably a lot cheaper than shipping from your county. I should get it in a couple days and will let
You know how it works.

First power up: my A-axis motor becomes super hot, cannot touch it and it smells bad. luckily it did and still does work, I was testing movements when noticed the burning smell, quickly turned everything off and waited for 30 minutes to give the A-motor time to cool off.
After power up it became really hot again, even without moving it. A-motor coils measure 10.5 Ohm each (compared to Z-axis: 2.4 Ohm).
Consulting the forum teached me to lower down power on the Tiny-G.
Turned the potentiometer counter clock wise, test A-axis didn't work anymore, after setting it to +/- 30% clockwise it was oke again, and doesn't become hot.

Is this normal behavior? and what is the recommended setting for all motors?

Edit: Juha already shared his settings on the forum, they work fine! I think it's better to put this information in the manual, preventing possible hardware damage to builders motors or even worse...

As they should. For reference, the A motor is this: http://www.omc-stepperonline.com/09-nem ... -p-85.html, the X and Y motors are http://www.omc-stepperonline.com/09deg- ... p-122.html, and the Z motor is: http://www.robotdigg.com/product/100/15 ... pper-Motor.

Yes, you are right, I must put them to the main site as well, also the above links. Tomorrow, no I need some sleep.
