  1. Re: G540 and Mach3 Random EStops Fixed For Me

    Smap: Thanks, I have just by coincidence and by accident, just did what you suggested.
    I was debugging something else, took a guess and set the pins to 0( i think that is what i did).

    Re: Poll: Acceptable lost steps?

    ger21: A properly working stepper setup shouldn't lose steps, got it.

    A back of the envelope calculation: if a 10" long piece of steel raises temperature by 5F, it expands by .0008".

    Arizona:20320 steps per inch.

    My parts run for 3-4 hours, @11, lines. I can in the end live with my missed steps. I was just wondering what is normal?

  6. Re: Strangely losing Steps in X axis. Help pls!

    Review your decision on micro stepping. I have read opinions, possibly true, that micro stepping decreases torque. If you do not get a benefit from it then try not doing it. I think that in a setup...

    You could definitely print parts with the correct shape/dimensions but you are right in questioning how long they would last.

    Re: Stepper Motor Issue with X2 Conversion

    You said F200, are you in metric? If you are not in metric then maybe 200 is too fast. Stepper motors can stall. Go into settings for your controller and verify what the acceleration is, try reducing...

    Re: CNC Red Cam Help

    First off check that a laptop is OK. A while ago is was conventional wisdom that the parallel port on a laptop was not OK. It had to be a fullsize PC. I may be out of date though.
