Invalid Gcode ID:33

[Anonymous]

Being a new user, i didn't worry the first time this occurred.  But this same error has popped up on a second mill operation. When it occurs the program shuts down and is not recoverable. START OVER 

Background; running a Shapeoko 3xl with Fusion 360 coding.

So my question is what the heck is error 33??

Help have been learning F360 for the past month but this is just frustrating as the simulation worked fine.

Hi @Anonymous

Welcome to the Fusion 360 forums! I'm not an expert on ShapeOko but it looks like in the Carbide3D syntax error:33 has to do with rounding on arcs. You'll get this error when the X and Y components of an arc are rounded too much for the controller to understand. Switching to metric might resolve it. If not, adjusting your post processor to output more decimal places of precision will. This is an easy modification - go into the post processor dialogue and hit the "Open Config" button or open the post processor in something like Notepad++ and look for the line below. Change the "3 : 4," which means 3 decimal places for inches and 4 for metric, to something like "5 : 5" so that the arc will resolve.

Let me know if that helps you out!

Just to let you know I have been getting the same error, I have tried changing to mm, I was unable to find the line in the gcode file produced using post processor for Carbide3d. I will run it with the mm changed, and I will let you know how it goes.

Hi @Anonymous,
Welcome to the Fusion 360 forums! This isn't actually a line you'll find in the G Code produced, you'll need to go into the post processor itself. If you go to the post processor dialogue and hit the "Open Config" button instead of "Post", you can view the post processor code. There you can find the line of code I mentioned. Change the "3 : 4," which means 3 decimal places for inches and 4 for metric, to something like "5 : 5" so that the arc will resolve. When you do that - save the post processor as a new name with the .cps extension and make sure to select your newly modified post processor in the post processor dialogue when you next try to post code.

Let me know if that helps you out!

When I click on open config nothing happens

Hmm... that's odd. Do you have Brackets installed? It should open that window.

You can also download the post here and open it in the text editor of your choice to make the change.

Thanks!

I shut fusion 360 down and reopened it config opened after that. So far the milling is working, and has gotten past the point I would receive the error. Thank you
