I bought a Bridgeport Series 1 CNC Machine planning on retrofitting it. Now I have the time and money to make it all happen, but I still need some advice. I am pretty well along at this point, and I have learned so much, but I want to hear what your advice is because maybe I'm doing something that is obviously wrong to you, but makes sense for me. So, this isn't the first CNC project I've done. I built a desktop CNC 3 axis wood router Dremel tool CNC with Mach3, NEMA 23s and a Gecko G540. Basically a educational starter project. I purchased a used Bridgeport Series 1 CNC for a price I couldn't pass up. The machine is in superb condition. It look like it wasn't used. It was purchased from a local university. I got it going pretty quickly with Linux CNC, a 48V 10A power supply and the same Gecko drive. It's nice and fast, but the z axis stepper motor was losing steps, had low torque, and the G540 drive isn't meant to drive a machine of this size. My end goal is to have this machine be fast and accurate, basically something that I could make some money with while I go to college. I don't want to use the original steppers just because one of them already seems to be having problems. Are there any good guides I should read through before I lay down my money and buy a power supply, break out board, motor drivers and motors? The person I bought it from included 3 servo motors that I think would be suitable for the upgrade. Are there any threads I should read of someone who went through a similar situation? I already had the machine making chips. I'm open to all advice but right now here is my plan. I
