I'm getting ready to buy a G9036. When I do, I'm going to convert it over to CNC right away. This will be my first conversion and I want to make sure all of my ducks are in a row before I start.
According to my calculations, I need to use a stepper motor that is approximately 958 oz for this lathe. So, with a 20% margin, I planning on getting two of NEMA 34 High Torque 1200 oz-in motors. Is there an advantage to stepping up to the 1810 oz-in or should the 1200 be ok?
With me using stepper motors this big, I cannot use the G540, so instead for electronics, I'm planning on going with (2) KL-9082 step drivers, (1) KL-7220 72v power supply, (1) C10 Breakout Board, (1) 5v power supply for breakout board. (This is basically Keling's cnc 3 axis kit less one driver and motor.) Is this a good way to go, or should I be looking for Gecko equivalent? I'm pretty much lost here. This is the first one I have done and I really don't know any pro's or con's about any of theses setups. Should I go with a digital stepper motor driver instead? Also, there were a ton of power supply unit options. Is this the best one for my needs?
On the software side of things, I'm planning on running Mach3 but my question is; do I need lazycam? I don't care about the $75, if I can use it and it will help, great, if not, no point in getting it.
When it comes to ball screws and what not, I'm lost. I noticed a while back, Crevice Reamer retained the factory screws and just adapted the motors to work. Is that a good idea or bad?
If retaining them is ok, why not just hook the motors up to the handles, instead of mounting the Z on the end of the unit?
If retaining them is a bad idea, where is a good place to get them and how large should they be? I'm not impressed by keling's offerings. So, I have been looking elsewhere, but there are a ton of companies that make them and I don't know enough to know good from great or bad from good. Any help here is greatly appreciated.
