Impossible to Upload Gcode file with CRC activated

Philippe71

You can close the Topic, I made a backup of MicroSD card of the DUET3 then exchanged the MicroSD card to a new one, uploads are OK with CRC now !

Duet 3 6HC + Duet3 EXP3HC (controlling 2 heads + Bed leveling)
RRF 3.2.0beta4 on both cards, DWC 3.2.0beta4, Static IP

Impossible to upload a GCode file to the Duet (Gcode size is about 21 Mb).

If I activate the CRC I get messages :

If I do not activate CRC, the file upload, but when I download the GCode back and compare to the original, there are 3 differences

The error text in GCode :

Tried :

3 different browsers (Firefox, Chrome, Brave) and more than 3 try per browser
Connecting the machine on the same RJ45 Switch (1Gb) than the PC
Uploading from 2 different PCs

Any Idea or thing to test ?

Thanks

I guess CRC was doing it's job. Glad you figured it out.

I had the same problem since yesterday with rrf 3.1.1. If I upload to SD1 everything is fine, Sd0 doesn't work. When I'm connecting over hdmi, I can see that the apache server doesn't start o think 3 or 4 services have status failed
