MemberI had Fusion update their post processor. It is now the default to not post arcs. I have a few post processors that I use. The new stock one, the old stock one and an old one the only uses mm. I find the problem is arcs in inches but I can’t prove it.
MemberMy problem seems to be in the 4 digits of precision in the j parameter. I edited the code to be only 3 digits and it is boring the holes correctly. I think it will resolve issue 181:
https://github.com/synthetos/TinyG/issues/181
Changing the post processor code in Fusion 360 to:
var xyzFormat = createFormat({decimals:3, forceDecimal:true});
var rFormat = xyzFormat; // radius
var abcFormat = createFormat({decimals:3, forceDecimal:true, scale:DEG});
var feedFormat = createFormat({decimals:(unit == MM ? 0 : 1), forceDecimal:true});MemberI have also tried switching the cut from climb o conventional to force the G2 code with no luck: (The first hole is a plunge and the second hole is a helix.)

Z0.0245MemberI just tried the modified post processor linked earlier in this thread ad for this problem it made no difference.
MemberI have had this problem as well. I am running Firmware .97 and build 440.20. I use Fusion 360 with the stock processor and run in inch mode. I hav found the large circle problem to be intermittent. I have tried going after heat and RF problems with limited success. Yesterday I was able to find a short piece of code the back simulates correctly and fails 100% of the time. It is two holes and the first one just plunges and the second one cuts correctly.
