Plasma 4' X 4' "How much can you haul in a blue truck"
First post, 4' X 4' cut size
Hoping for some advise, with my plasma table ,i have looking at keling cnc packages 495 oz in 36v nema 23 ,I called them they could not tell me the torq curve for the motor wouldn,t that be the target RPM for gearing? I have also heard that running the motor to fast will lead to in accurate steps ,the other way the motor is sluggish They did say that speed is not HP . I would think that a table that runs a router would need to have alot more power than a plasma torch? I have the base built with a water cavity under the grids.I am leaning to rack and pinion on X and Y my x having a common shaft and drive both sides at once using 1 motor . Direct drive Z with a ball screw 12".My "Bridge" as i call it made from all aluminum .I also intend to use mach 3 if that matters.Any thoughts on the matter would be GREAT !!
Do you know of a good company for steppers? Not Keling
Your right i have emailed keling 3 times asking for the torque curve of there nema 23 495 oz in 36v kit and all they do is answer other questions ,i even called and asked and the guy said there were to many variables i think they they don't know , I was referred to them buy a friend who has bought from them and was very happy. And yes it is a box if parts. I looked at another company who had a driver card and the motors plugged into it? I was looking at a 4 to 1 ratio over all compared to the rpm ? I think? I was inspired to build my own table after watching the PLASMA CAM video there id nothing high tech there other than when they cut there is no smoke ?
