Guys, I made a file of 660 mount in Inkscape that was 67.kb and when I was done in Makercam it was 5.5mb after I exported it from Makercam . I then tried to import it into Chilipepr and it was two big . Is there a setting that i am messing ?
Can you post a screenshot or some of your settings?

I have not used Makercam, does it have a backend settings option? Limit your precision to 0.02mm or even larger, tinyG can’t do anything with shorter moves anyway. We have seen this from several 3D CAM programs - generating Gcode with 6digits after the decimal! See if that will help. Maybe post the first 1000 lines or so over at Google Groups -Chilipeppr, where they are easier to read.
Kurt - there are a couple different GCode plugins available for Inkscape, they are a bit fussy but do work.
None of those images worked. Maybe a video? Or put the images on public URLs? Or create a new post from scratch?
well i changed my precision to 0.02 and that made the file a lot smaller , now i just need to see how i can make the number of pass’es smaller and i thank that should fix the problem .
The strategy I have used to make multiple cuts has been to set my first zero on the material surface, make a first run with say .3mm or so, then when it was complete set another zero 0.3mm lower, then run code again, etc. Not very elegant, but works. That was before CP, which may provide more sophisticated support
Will , thank you Carl I was able to make my first part it came out ok, So I was able to change my precision 0.02 and then when i was entering in the bit size i took the diameter of the bit and divided by the the size if the bit . So if my bit is .1250 then i divided it 2 and that gave me .0625 per pass and if my stock is .50 then that gives me four pass’s . Seems too work ok . the file sizes went way down to like 36KB so i should be good to go . So Thank you all !!!

I assume you are still talking about MakerCam, so I am somewhat in the dark on some details. Apparently MakerCam takes bit diameter into account - that’s is good and usually necessary, So an offset to outside your desired cut line of 1/2 the bit diameter is correct choice.
The depth of cut is a separate issue, Assuming that you can cut the material you have 0.125 at a time, 4 passes is correct (4*.125-.5). That has nothing to do with the bit diameter… But, in general, the larger the diameter of the bit, the slower you will have to move, to allow for material removal, but you will have to experimentally determine that speed (Fspeed in Gcode).
So the good news is you got your first part!, I’m just not clear how you managed to cut ).5" in 4 passes that were 0.0635 each (4*0.0625=0.25"). Clearly you are on the right track and I think you will like the 660 when you are done, If you cut plastics, you may find that the 660 is too much RPM, melting the cut rather than cutting. You’ll have to experiment.
