happy new year to all!!!!!
I have recently purchased a 3 axis driver (the generic cheap ebay one) and I am quite happy with it so far (almost a year still running, $78 bucks, can't go wrong). I have been using 78oz-in NEMA 17 motors on my pcb machine, but now finding they are WAAYY to underpowered for my new aluminum beast..
I was looking at upgrading to the 425oz-in NEMA 23 form John at Keling inc. They are rated 4 volts at 2.8 amps per phase but 8.4volts at 1.4 amps when wired in bipolar series.
I understand that the advertised max rated power for my driver is a huge exaggeration at 3amps 36v MAX.. However I cannot understand how the same ebay seller (savebase) is also selling the exact same driver but with NEMA 34 motors rated at 833oz-in at 2 amps included with the kit. how is this possible???? Although it wouldn't be devastating, I've never been to fond of seeing a plume of blue smoke bellowing from my electronics. I just wanted to make sure these motors will work before I go out and but a better driver.
some insight would be greatly appreciated
