Hi All
I've been considering building a CNC plasma table for some time now. I've finally got some funds together and am ready to pull the trigger.The problem is I don't know where to shoot. The research has just made me more confused as I learn more about ways to accomplish this.I'd like to collect the bits to get this built over my Christmas break from work.
I'd like the table to be a 1200 x 1200. I will probably make it around 1300 x 1300. I'd love for it to be 2400 long, but just don't have the room.
So some specs I've decided on and would like some input on are.....
1. Nema34 motors to drive the carriage (I'll use one each side).
2. 20mm x 5mm pitch ball screws for carriage. With 200step motors this gives about .001" per step mechanical resolution
3. sbr20 slide rails for the carriage and sbr16 for the other axis's.
4. 72V Power Supply.
5. Gecko G203V stepper drivers
So my initial questions come down to...
1. Where can somebody get a reliable 72V 20A power supply from
2. What Breakout Board would be recommended for the Gecko G203V.
3. Is there a supplier somebody has had good luck with for Ball screws with machined ends?
I'm sure I'll have plenty more questions.
Damo.
