Safety error message I cannot see in the book of Prusa
I was loading filament for todays fun. I set the printer to pre-heat for PLA....wait.....inserted filament (properly pointy)..watched for nice new colour (in this case crystal clear) but as nothing came out when asked if correct colour came out I said No. Watched as filament came out...said yes to correct colour question and set up print from SD.
Display showed the error message "Heating Disabled by Safety Timer".
As far as I could see all was fine and on 2nd shot at print from SD all appears well. Have I missed something in the book when speed reading?
Is there perhaps a timer set that watches the autoload and flags an error when it believes everything is hot enough and you should have the correct colour by now?
Possible coincidence. This particular filament is from a brand new spool of Filamentum Crystal Clear PLA from Czechoslovakialand. It failed on a second print on Friday by way of a random blockage 3hrs into an 8hr print. Cleared this (cold pull and lots of sweary words) and purged with a known good filament. Printer and all components run time 105hrs....(low hours not my fault my wife doesn't trust it to play safe in the house).
