Re: [CAD_CAM_EDM_DRO] Re: XYLOTEX VS GECKO DRIVE ?? why ?

Mark,

I also got a lot of service out of my Camtronics 2A kit. But I fought with
an extreme resonance issue the entire 1.5 years that I used it. I had to
configure all of my feedrates based on where the resonance band for each
motor was and not on the ideal (or even close) cutting speed for the job.
Most of my G-code files are about 5000-10000 G01 moves of mixed angular and
linear axes. I had to calculate a feedrate for each move that would bypass
the resonance band of each motor.

With the microstepping Xylotex drives (which are cheaper than the Camtronics
kit was 1.5 years ago), I have been able to cut my program run times down
from 60-90 minutes to 8-12 minutes. I can now program feedrates without
regard to resonance issues, since they have been eliminated.

Also, thank you for the compliments on my work. Contact me any time you
would like.
