CamBam help (General usage) / Re: GRBL Ierror #33 with some G3 lines.. can you take a look at this?

I'm glad the problem was solved.

I'm curious, do you intend to make musical instruments with your router
My Brother (nearly retired now)  makes guitars,but refuses to use a CNC
He prefers to use the "Old School" methods and tools.

HI Stefano

I've just had a look at your file.
It runs now, what you need to do is modify the Number Format string so that it looks like this
--->   0.00#    once modified you have to then save the PP and reload it.
Happy CNCing


p.s.
I would like to attach my edited GRBL post processor but I can't find it.
In the C:\ProgramData\CamBam plus 1.0\post there are only the "default" ones.
Could you point me to the folder where "custom" PP are saved?

What you do is make a copy of the whatever the default PP that you want to use  and edit that, else
you have made changes to the default one.

Try using this new version where "Max crossover distance" has already been set to 0. https://cambamcnc.com/forum/index.php?topic=3513.msg71282#msg71282
It's for CamBam v1.0 only.

Scripts and Plugins / Re: V-Engrave Plugin

« Last post by EddyCurrent on Yesterday at 10:36:07 »

This issue has been reported many times in the forum;
"Between each letters of a word and between each words, the vengrave plugin leaves an engrave line as it moves"

The stock answer being;
"To remove the "bridges" between letters, set "Max crossover distance" to 0"

In an attempt to prevent this error in future I have added this line of code to a new version 1.2.0.3
 
mop.MaxCrossoverDistance = new CamBam.Values.CBValue<double>(0.0);

Please find version 1.2.0.3 attached

I tried changing the PP's
Minimum Arc Length = 0.019
a higher value just to check if a significant change there would change something, but had no luck...

The GRBL documentation has a parameter about arc tolerance, it's default to 0.002mm, really don't know if it's related to the problem.
https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration#12--arc-tolerance-mm

The strange thing is that the error is related only to G3 commands (but not all the G3), it never triggers with G2.

On a side note I Easel (the software that I used until now to generate my GCODE) never generates arcs (G2 and G3) but only linear movements.
That's why I never got that errors before (this stamp it's my first CamBam project).
Probably I could resolve changing the PP setting "ARC Output" to "Convert to lines"... but since GRBL does support G2 and G3 I would like to understand the origin of the error.

p.s.
I would like to attach my edited GRBL post processor but I can't find it.

No Gcode file attached

Ops 

First of all thank you for your help!

This time I attach the file for real  as well the CB file too

Hi Stefano and welcome
...
 I suspect that you you've not selected the PP (GRBL) from the drop down list.

Thank you Dave!
I'm pretty sure I selected the GRBL PP, but I'll double check it anyway.

I think that GRBL fail on very small arcs ..
...

In Options section, change the following values:

Minimum Arc Length = 0.001
Maximum Arc Radius = 1000
Number Format = 0.0###

It could be...
I'll go trying your settings.

Meantime I attached the missing files

Thank you again for your friendly welcome and help!

Thanks Eddy, I thought this might be difficult to do without the extra libs.
