How do you rate your experience withe the Arcsin Controller plans? I built his original pikeresque plans and it seems to work great so far. However the plans weren't detailed. All I got was a PCB layout and a parts list when I ordered it. Your contoller box looks very nice. Did the plans describe how to build it? |
I tested the speed of my y axis before pulling it apart and I measured 32 ipm at max speed of the steppers with Daves controller using the manual joystick so I am assuming that if you are getting 60 ipm with 1/2-10 your motors are spinning faster than mine and I also think that I will have to cut at a much slower speed than the 34 ipm so I can maintain torque on the motors, I will be more informed once I have the controller hooked up to the computer.
Still waiting on linear rails from e-bay he finally answered my e-mails and said he has sent them today (1 week after I paid for them) some people are just slow I guess.
I found that my y axis bearing trucks are not quite parallel with the rails so I have shimmed the narrow side with some brass shim and they are now aligned much better, I will definatly be cutting out my next machine with the cnc to avoid these misalignment problems.
