Thank you for this answer.
I've asked to my client to check those points to see if there is something that can be related to the SD card.
One of my client is experiencing an issue for printing a part.
The error message is this one as attached below :
Error: G2/G3: no I or J or R parameter but no G2/G3 in Gcode file
I've carefully checked and the Gcode file does not hava any G2 or G3 command inside (as it's a bit heavy, I can't paste it here).
Anyway, there is something during the print that make the Duet believes that a G2 or G3 command is issued but there is nothing like that in the file.
For information, it's a 90 hours print and the problem as occured after about 20 hours.
Do you have any idea or similar behaviour ?
I attach also the config.g file :
Thank you for your information if you have some.
