The pp that I am modifying produces a string of

G1A0.000
Move y
G1A360.000
Move y
G1A0.000
Move y
G1A360.000
Etc

So the rotary rotates back and forth and slowly moves down the object to round it into a cylinder.

Tomorrow I will send you the pp gcode and output.

Hi Randall

The following pp is the one i have modified. The resulting Toolpath which i have not run yet is included also. Your cursory look would surely be appreciated.

Thanks

John

They look fine. I'm curious why your toolpath files have a .PP extension.

Hi Randall

I was using onz…. Post processor to modify. I took your suggestion and added a post_name and a rotary_wrap_x = “A”. It would not work. I looked and looked for the bug and found that taking out a P in a g1 x y z p f it all worked. It was like the blind leading the blind. I still have a rotation problem. I need to change the multiplication factor in a x variable. I have a 100:1 rotary drive so with 1.8 deg step, and 100:1. How must x be multiplied by what to equal 360 deg. I think that is the problem. I came up with 55. Do you have thoughts. I am going to try it out this afternoon.

Why *.pp, I found that placing a pp in the pp list requires a *.pp. I know that doesn’t make sense since there are other extensions in the list, but it works. Again, do you have any advice.

Thanks for your guidance

John

Again, do you have any advice.
First let's get the basics of the machine figured out.

Checking Rotary Calibration
  • Put a piece of material in your rotary setup
  • Send the rotary axis to its home position with the command G1 A0
  • Put a pencil mark on the material
  • Tell the rotary axis to move one revolution with the command G1 A360
  • The pencil mark should be at the exact same location
  • Send the rotary axis back to its home position with the command G1 A0
  • Again, the pencil mark should be at the exact same location
  • Tell the rotary axis to move 100 revolutions with the command G1 A36000
  • The pencil mark should be at the exact same location
  • Send the rotary axis back to its home position with the command G1 A0
  • Again, the pencil mark should be at the exact same location
Let us know the results.

That is truly extensive, more than I had thought of. Will do, but grandkids come in tomorrow, so it may be a few days till i get some results. I will also have to make some adjustments along the way possibly. Possibly for sure.

Since i don't have control hooked up to my cnc is there a way to use INTERFACE to send code pieces. If not i might have to write a gcode program to run pause run pause etc.

I have no idea how your machine operates so I cannot advise.
