hi Conan

If i could give you some advice at the start it will be hang on to your money until the last possible moment. I messed around with so many ideas and jumped the gun by buying acme screw rod here and grabbing bits of metal there, I could have paid for upgraded motors and higher ampage drivers to take them with money i wasted. Once this one is finished i will be building a bigger unit and the kit i have for this one will go onto a smaller machine with better quality components. What i paid for three power supplies could have paid for decent high ampage single unit (i was planning to use free motors on a smaller unit and one would have been enough).

You must be honest with yourself about what you will use it for - cheap is not always a saving
