Hi Irving many thanks for your help. The driver I have was from the Alien CNC kit that I prchased about 4 years ago and have decided to use this for my small machine with the Nema 17 motors and keep the 23's for my bigger build and purchase some good drivers for this, so not to let it go to waste I will use it on the little one as this machine will not be demanding so fingers crossed it should work. Once I have learned to use the machine and using CAD and the correct software it may give me the drive then to finish my bigger machine so I can use both of them efficiently. I was going to use a laptop for working the little machine and the big one but have been advised that power issues are a big problem with the Mach3 software. In saying this how would a laptop fair if it was being used with a constant power supply ie being plugged into the mains everytime you wanted to use it and then switched off when not in use ? The reason being is that I really didn't want to keep a computer in a cold shed and this being affected by the weather might be trouble and not safe to use, so the laptop rout was what I was thinking, bring it in, hook it up, do the cutting then bring it inside ?
