I have two problems with it and both are equally disturbing.
#1 - circle comes out to just over 3.75" in diameter.
#2 - circle has a small (1/2" x 1/2") pac-man mouth in the 2 o-clock position
Machine is a Hurco with Ultimax. Code comes up on the display after being dripped in and it's the same as shown above. Double checked that everything is in inches.
Anyone have any ideas? This stopped being fun a few days ago.
Re: This should not be difficult - Why is my circle so big?
Hi ecdez.
Numbers are good.... assuming 3/16 tool diameter. It's odd that the "mouth" is at 2 o'clock. It simulates at 11. Perhaps a bogus code from the prior tool? Try adding G50 and G69 in the beginning.
Re: This should not be difficult - Why is my circle so big?
In my frustration and desperation to figure this out I posted the question elsewhere too and one of the guys there took only that section of code and put it in a program for his machine and got the the same result. Someone else ran the math and the arc dimensions come out to the same size as what I actually cut. In the Cam program thought (SheetCam) the hole is the correct size and a perfect circle. Only thing I can figure is that SheetCam may have a bug in the post processor for Hurco Ultimax. Other than that the program is pretty simple to use and I like it. Another user here has a post he modified for his machine that he's going to send me when he gets a chance. I'm anxious to give that a try.
Re: This should not be difficult - Why is my circle so big?
Why are you using 3 arcs, instead of a circle.?
Make the following changes.
Line N70 - Add G00, to this line.
Line N80 - Add G00, to this line.
Line N100 - Delete this line.
Line N110 - Delete this line.
Line N120 - Add G02 and F12.0, to this line
