I am having trpouble withy my Mach3 circle pocket cutting wizard. On smaller circles, the Y axis does not move. The code reads y0, and X is correct. What am I doing wrong? And can someone explain the "ramp" variable.
thanks,

Can you post a screenshot of the settings you input into the wizard please.

I cant seem to import a photo.
here are the values:
x center = 0
y center = 0
ramp disp. 80.0
pocket diameter +13.750
% stepover 90
federate 200
rapid height.1
feed plunge 5
tool diameter 7.4
depth 4.5
cut depth 1.5
thanks,

Ok the step over is your problem, 90% of 7.4 would be 6.66 so 9.4 + 6.66 would be bigger than the dia you are wanting to cut. Set the step over to 40% or less and it should work out fine.

Hood,
I reduced the overlap to 20% and am still having the problem. The code is not generating any movement on the y axis. Please see the attached screenshot and code.
thanks,

Hi,
look like you checked inch instead of mm.

The code should be OK, it is calling a G3 starting at the Y0 position and the X value changes. If you look in the toolpath window you should see a spiral pattern.
As Alex has said you have Inch chosen, that will make it 25.4 times larger than you are wanting.

The pockets diameter I want is 1-3/8" . So I put in 13.75. Should it be 1.375? I'm. To using mm for anything on this particular job.

Not really sure what you are meaning, are you working in metric or imperial units?
If you are working imperial then you will need to enter the values as imperial units incl tool/depth etc etc.
1 3/8" is 1.375" or if working in metric then it is 34.925mm

Ok, I get it. My values are always 10 times more, so if I want to move x one inch I put in G01 x10. But this is not the case with the wizard. I'll try it now as you have directed on my machine. thanks,

No, if you set the values in the wizard as Imperial then you need to enter all of them as imperial units.
1 3/8" is entered 1.375 inch
If you work in metric then you will have to enter all values in metric, so if the dia you want is 1 3/8" then you would enter 34.925 as that is the metric size for 1 3/8 dia ie 1.375 x 25.4 = 34.925mm
If you want to move X 1 inch and your machine or code is set to metric units then you would call a move of 25.4mm
If your machine or code is set as Imperial units (inch) then it would be 1
