We are obvously talking different types of machines. For a plasma cutter with a 4 ft table, I would expect that something on the order of 250 inch pounds to move the gantry, but double that for higher speeds ? It appears to me that those motors are very light ??? I was assuming that shotting for more than 20 watts was in order ? What driver would be best ? The Rutex and Geckos shoot for 70 plus volts and some of the links show 9 volts.... Is there a lower cost driver that would handle the smaller motors for half the price ?
