X/Y dimensional accuracy
Hi Folks,
Trying to identify options for improving the dimensional accuracy of printed parts on my vc3.0.
I'm printing some test squares and finding the following:
modeled x-y vs actual x-y
20 x 10 -> 19.89 x 9.93
30 x 10 -> 29.83 x 9.95
50 x 10 -> 49.73 x 9.93
80 x 10 -> 79.66 x 9.93
40 x 40 -> 39.70 x 39.71
Short of scaling every part in x & y in the slicer, is there a more universal fix that can be applied? Thinking about tweaking stepper rotation_distance for x & y steppers but want to open some discussion on it to see what others think might be a solution.
I have another printer that results in much more accurate sizes without scaling in the slicer so I feel like this can be done, just not sure what the right approach would be.

Mid-print, mcu lost
Hi folks,
I've had this error repeat twice in a row now. Mid-print I'm getting a 'lost communication to MCU' error. No other information is available in the interface.
I can get a console on the pi. Wondering what debugging steps I can take to track down the specific cause.
Are there log files I can look at? Would you suspect the board or something else?
The only thing thus far that seems to resolve the issue is power cycling the printer.
Thanks for any help!

Rapido repair
Hi folks, has anyone successfully repaired a rapido hot end with an intermittent thermistor connectivity issue? Wondering if possible or if it's advised to just replace the whole core.
Thanks!
