Hello,
I noticed these Warnings after downloading a file to the controller. I don’t know why or how to correct this. Does anyone else?
I use Maker with the OneFinity inch file format to generate the code.
Thanks

Forgot to show an example of the many warnings:
| Warning | 230 | Arc radiuses differ by 0.00100442mm |
| --- | --- | --- |
| Warning | 234 | Arc radiuses differ by 0.001mm |
| Warning | 251 | Arc radiuses differ by 0.001mm |
| Warning | 362 | Arc radiuses differ by 0.00100235mm |

Not sure that something as small as a thousand of an inch is going to all that much of a problem in woodworking … perhaps metalworking.

Hi dave,
In this case size doesn’t matter 🙂 I’m wondering why the warnings being are generated.
Thanks

Perhaps something to do with the post-processor you are using?

Hey Ron - which post processor are you using? It might have something to do with the gcode for arcs (G02/G03) vs the arc ‘fitting’ with small sequences. But a thou of a mm is quite small.

Hi Tom- OneFinity inch with Maker post processor. Another point of interest might be that I see the warnings when I upload from my PC using Chrome but at the controller I do not see them.
Thanks for the reply

Hmmm, I don’t know have that SW so I can’t try to duplicate the results. If you can, upload the gcode and I will see if I get the same error. Or maybe you can load it into the [demo](https://demo.buildbotics.com/#control) site buildotics provides - you might be able to reproduce it there.

I have an email in to support as well. The file runs fine so I’ll see what they conclude.
Thanks for the thoughts

Warning 3 Not implemented: G64 (Set Best Possible Speed Control Mode)
Any ideas what this means?

Is there a list for what these different warning codes are for. It would be nice to have some kind of reference chart for these. I have seen plenty of posts about the z position warning. (which I learned can be triggered by having a short bit too far in the collet) but nothing on some of the other ones.

I think because you can’t control the speed of the router with the controller. I have been told to disregard the warnings I see from my PC uploads to controller.

when i googled that code I got G64 rounds the g code geometry and the G64 parameters adjust how much rounding to do.  It has something to do with the angles and the geometry not being efficient. I just couldnt find anywhere to explain any of this code or how it relates to what adjustments I should be making.

[http://linuxcnc.org/docs/html/gcode/g-code.html#gcode:g64](http://linuxcnc.org/docs/html/gcode/g-code.html#gcode:g64)
I found docs on the g-codes and what each one does. This information was not the easiest to find.

Anyone else get the “File is large - gcode view disabled” message?
I found it amusing : )

Yep… Makes me sad 🙂
