I retro'd an X2 with Ron Steele's cnc kit but I'm not happy with the rapid rates I'm getting from the stock leadscrews on the X & Y axes with newly made acetal nuts.

I've been reading for weeks prior to raising some questions.

I.m currently using the c11 Rev 7.2 that opto-isolates the xylotex 4-axis board. I have the xyoltex 24v board and am using Keling's 425 oz stepper motors.

I get tired of the motors stalling when trying to get rapids higher than 20 or 25 ipm at startup. I can get higher rapids after the screws & lube has warmed up. Sometimes I have gotten up to 50+ ipm but I had no confidence of maintaining that during a run.

What I know is that the G540 can only handle 3amps, my steppers are rated for 2.8 so what would I gain by using a 48v PS that can deliver 12.5 amps?

I haven't pulled the trigger on the purchase because I've also read their are other options out there. From what I've read, it seems like the G540 has been proven easy to hook up (not that others aren't as well).

Do I need to totally remove both the xylotex and the c11? Can I get by using the c11 along with the G540, essentially just replacing the xyoltex with the g540?

Would I be okay just using the 24v PS that I currently have?

Any thoughts/comments would be appreciated as long as they're civil. I'm not here to start a flame war as I seen elsewhere. Opinions are okay, just don't carry it over-the-top please.
