Rob, my screw have only 1/4" pitch. Pulse/mm is correct at me, every size of parts is between +/-0.01mm. Bearing fits in the pocket, like eggs in the mouth of a dog :) Unfortunately controller sends false command to the driver, and only when is a smaller diameter of pocket Perhaps this is a firmware error... |
| old Zozo:
waoooo !!! Rob, you are the other God of this forum :) (Pardon, No.1 is Benedikt) I thought, is it possible, controller hates low pulse/mm? I set 1000, as yours controller. Happen wonder! G-codes are running right! I will increase value of puls/mm and all are right :wave: |

Zoli, your words are way to kind. I set the pulse/mm by dividing my micro steps by the ballscrew lead. 25,000 microsteps/25mm lead =1000pulse/mm The eggs in the dogs mouth is about the funniest thing I've heard in a while. That's what I already love about MadModder. There are so many colorful people here so willing to be real. That's a treat for me. Rob Sent from my SAMSUNG-SM-G900A using Tapatalk |

Rob, I like this forum as well, I've got a lot of useful advice here. Even though my English knowledge is very poor :) Important for new arrivals: I tested my controller still. value of pulse/mm never be under 250. If it is 250, accuracy of my controller is X0.002 and Y0.001 If this value lower, the tool could overstep a bit. |

My controller arrived from china yesterday. It will run this little machine one day... http://www.cnczone.com/forums/benchtop-machines/142459-small-aluminium-cutting-mill-4.html Is there a change log listing the overview of changes so far made to this controller? Mark |
