G-Code, CAD, and CAM discussions / A Simple BobCad V25 Job, or So I Thought!

Oh the joys of learning.
   Congrats. I understand the excitement. It is just watching a robot (CNC machine) do the work I find amazing.

You can't use pin 0.

   On the Mach set up screens inputs section there will be a specific set of pins that are listed. You must choose 1, hook your estop to the pin specified and then enable it and acknowledge which state it will be in active or low.

Brett does too. Even when dead tired solving the rest of our problems!

General Mach Discussion / A axis isn't working

Ok no mechanical advantage or reduction. I was just verifying as the problems seem odd.

Why don't you suspect noise? What happens if  you raise the debounce to 2000 or 3000 as a test.
Shielded wire on your switches? Is the shield connected only at the controller to the star ground? Do you have the V- of your power supply landed there also?

Does it have a worm gear?

Yes - the drive motor is connected to the a-axis shaft via two timing belt pulleys and a XL belt. Both are 15-tooth at .2 pitch. That would mean the distance of travel for one revolution of the motor would be 3 inches.

How can you translate degrees into linear distance? If both pulleys are 15 tooth there is no gearing. It should be microstepping value 1/8 the you said. 200x8=1600 steps per revolution of the stepper. Is there a picture of this set up? The actual A axis?

Is your axis direct drive? Otherwise I would think 200x8 (microstepping)x360 or either 200x8x reduction value.

BTW my USB version works well just the ESS is more resistant to problems in my understanding.

As much as I enjoy my PP controllers they are a dying lot. Xp is great but getting old. SS is a great product once configured (dont take any shortcuts in set up) just get the ESS version not the USB.
