Hello Jonathan, is there any power supply do you recommended? Jazz told me to buy this [URL="http://www.zappautomation.co.uk/en/digital-stepper-drivers/318-2m2280n.html"] but I have the same problem( I can only buy on aliexpress and ebay) maybe you can recommend another power supply so I can find it, I dont now if I need one or more than one. Thanks,you have been of great help.
