I have two KL42H2150-42-8A Nema 42 2830oz-in step motors running the gantry on this 5 axis machine: http://www.cnczone.com/forums/plasma...a_10x5x24.html The motors are vibrating quite a bit and I cannot tune them to be smooth enough. I have tuned them using the trimpot on the Gecko 203V's & can get them pretty quiet at ~0.5rev/sec, but not silent & at some rpm they are really noisy. I am using Gecko 203V's at 6amps for drivers & 72V (KL7220) power supply. Is there some other way I can tune them to run more smoothly?
I have it running on Pacific Bearing 25mm Profile Rail, could this have anything to do with it if it were in need of grease?
They are 8 wire motors & I have them wired Bi-polar parallel, will a different wiring run more smoothly? Lower voltage? Seems to be vibrating way too much.
I spoke with Keling & they are sure that it's not the motors as they have sold hundreds of them & have not had any problems + they say because it's both motors doing the same thing, it's most likely some other mechanical issue. Any ideas anyone? Thanks in advanace.
Cheers!
