GCODE generated by Fusion 360 for GRBL sending error 33 on G3 command
Trying to do a rather detailed 3D lion face. After generating the GCODE using fusion 360 and GRBL post it runs fine in simulator mode but I get this error when running it in check mode on UGS.
{Error} An error was detected while sending 'G3X1.546Y-0.4092Z-0.9575I-0.011J-0.0006' (error:33) Motion command target is invalid. Streaming stopped.
It did CHECK OK in UGS on a number of previous G3 commands.
What am I doing wrong?
Thanks

Can your control handle I / J code with 4 decimal places 0.0006.

Sorry, not very technical, What do you mean by "your control"?

If not, how would I change that ?
This is the part (Computer GRBL in your case) that is reading your G-Code program and makes your machine movement.
Re: GCODE generated by Fusion 360 for GRBL sending error 33 on G3 command
Hi 002 - Look up error 33 in your machine controller manual. What mactec is saying is the machine controller may not read to 4 places in the J line. But the other co-ords are to 4 places... Peter

That is not correct, this is standard programming which he is doing, X Y and Z can work together simultaneously without any problems, no 4th axes needed, there is a problem with the I / J that the control does not like.
Re: GCODE generated by Fusion 360 for GRBL sending error 33 on G3 command
Well I am running GRBL on an arduino uno R3. Grbl has limited documentation. Lets just say that GRBL cannot handle the code to 4 places. How do I fix that in Fusion 360?
Thanks

running simulate in Fusion works just fine.

Try these 2 Programs and see how they work with your control. (Air cut) The (2) programs are just cutting in opposite directions, .250" cutter Diameter, if these run ok then your program is the problem. in the Snip the Center X0Y0 is the center of the circle

That would have to be changed in the Postprocessor, not in Fusion 360, get a better control.
So, what I just posted most likely won't run as well as it is 4 places worth a try though.

If the machine measurement accuracy is 0.001" the fourth decimal place will remain 0. If it's 0.0005" the fourth decimal place will show 0 or 5.
The control will ignore the fourth decimal place value if it is only accurate to 3 places.
It might throw up an error, but I don't think so. But it might give steps in the surface finish.
I think your program is the issue.
More Bs, the control he is using will not ignore the 4th decimal place, it only supports 3 decimal places. that is why he has the error so, he has to change his Post Processor, to output 3 decimal places.
