Hello @3dtechs!
I was using Robert the X1 Carbon on the right last night and my polycarbonate print failed. There was a warning about the X axis with a suggestion to clean the carbon rods and tension the belt. @Lia and I did a calibration and wiped the rods but we didn’t tension the belt. We did a quick test print and it was successful, but seemed to have bits of the previous filament in the print. There were no warnings after the calibration but we think it still needs to be looked at.
Also I’m experienced with SMD rework so let me know if I can help with the micro SD card socket, as it was just barely working even with the card extender.
Thanks!
Sam
