Now, there are a few things that I would like to clear before I flick the switch;
...

Thank you Marcus ! I suspected that might be the case but just wanted to make sure. I don't want to release that special smoke that electronic components are filled with :)

I'm planning to mount 3 gecko G201X's on single large fan assisted heatsink.
Do they have to be insulated from the heatsink and each other ?

Thank you

Thanks for explaining it to me. I think I will try Gecko G250 driver board. At least it is standard board that a lot of people use... And power supply, well I will see what comes up.

Thank you Steve !
I managed to get things under control by fitting 2 resistors in parallel (0.47 and 2.7 - total of 0.40 ). Current can be adjusted on vr1 now. Maybe I will fine tune it further...

I have fitted insulating washers on both ic's, as per kit instructions. If there was short circuit through the heatsink, ic's would probably go up in smoke as soon as I turned the power on...
Vr 1...

Hello !

I'm having a bit of a problem with my current limiting resistors, I'm using Oatley electronics driver board with Oatley electronics constant current supply for steppers and 20V 40A power...

Hello !
Does anybody have any data on Sinano electric 4H5618S-69 stepping motor ?
I tried searching the web, but I get 0 results every time !
It is 24V 0.3A/phase, 1.8 deg step.
But I would like...
