Large Gcode number causes error in WebControl - have to restart at next line

Troubleshooting

I had this one spot in my design and the system stopped with an error every time around, except when it cut off on a literal tangent twice.

code:

G02 X468.1353 Y273.1857 Z-8.0000 I-36726.9630 J1234.0951
G03 X467.3183 Y249.1190 Z-8.0000 R836226.179450
G02 X471.8497 Y263.7913 Z-8.0000 I2487.2178 J-760.1286

the R 836226.179450 is the line that made it die each time. The first time it did it, I patiently waited and waited, but I was able to go view the gcode to figure out what line because the router was still there. Thankfully the WebControl go to gcode # allowed the program resume right where it had stopped. This had to be done 5 times on this one drawing. What is the maximum radius the arduino gcode parser can handle?

@blurfl, did the large arc change you make work with R or just I/J?

Looking at the firmware code, I donā€™t think R is supported at all, just I/J.

@madgrizzle, youā€™re right, the firmware only supports arcs using the I,J relative mode.

@Orob, is the gcode generated for a machine that is ā€˜grbl compatibleā€™? Many programs will adjust their gcode output format for a variety of machines. The Maslow want to use the settings often listed as ā€˜grblā€™ or ā€˜grbl compatibleā€™.

gcode was generated with inkscape gcodetools.

The inkscape gcodetools seem to be abandonware, but you could try and post this issue on their English language forum

I use the free version of Carbide Create on my much smaller 3018, you may want to try using that with your inkscape svg file

I read up on this and apparently in inkscape gcodetools, if you have the postprocessor set to ā€œRound to value to 4 digits.ā€ then it will generate the R values. Make sure that is set to NONE.
