    Re: Raster to Vector Mastercam 18

    I found that selecting splines would cause mine to seem to lock up...and then half an hour later it finished doing its thing and completed the conversion.

    Re: Will this Router Mill Aluminium?

    I have a small chinese router that uses small end Nema23 motors.

    I do a lot of aluminum. I keep the rpms high say 20000+, depth of cut about 0.15mm or 0.005" with a feed rate of about 1000mm/min...

    250mm/min. steady as it went, it vibrated a...

  8. Re: Surface finish problems on pocket floors

    I can see two things happening here.

    You have programmed your tool to pocket it out in a zigzag pattern.

    Re: G0704 Z axis trouble

    hmmm...

    I think I would try swapping the z axis motor with one of the other axis motors...see if the problem follows the motor or stays with the Z.

    If it follows the motor, you know its...

    Re: OmioCNC report

    ok...I'm wondering if somehow the pulse count setting on your controller has been changed/corrupted?

    that would give you a stretch/shrink on the y axis...it is a computer, and these things do...

    5-8UN 2B LH:

    5.000" OD

    major diameter 5.000"

    8 tpi means thread pitch is 0.125"

    internal thread bore diameter = 5.000" minus 0.125" = 4.875"

    One thing I DID do when I got my machine was to slow down the homing speed.

    Mine would home at something like 3000 mm/min. Way to fast.

    Re: OmioCNC report
