Rossboss 0 Posted January 10, 2017 in Nozzle Will Not Cool The "wait a moment for Printcore 1 to cool down" progress bar on my Ultimaker 3 is frozen. I'm just going to restart the printer but this is not the first time this has happened. In general it seems like the cooling process is taking longer as well. Why could this be happening? Thanks!

neotko 1,355 Posted January 10, 2017 in Nozzle Will Not Cool Did you change the bed temp manually? I ask because I found a bug to make that and is adjusting the core temp +X amount while the bed heats. That creates a bug (that I forgot to write anywhere @daid) So. If you launch a print after a print. The cores MUST (silly imo) cool to 50C before they heat again (waste of time that must be for some security reason?). So, if while the bed heats you change one or other core to +X amount of temp, then the core never reaches the 50C that the firmware wants to start heating the cores. Did I explain myself? Basically, don't set an temp+ until the cores start heating, or you will be on the heating cores stage at infinitum). Share this post Link to post Share on other sites
Rossboss 0 Posted January 10, 2017 in Nozzle Will Not Cool This very well could be the problem as i did just adjust temperatures on the system yesterday. The restart fixed things for now but I'll keep an eye on it after I change bed temp again. Thanks! Share this post Link to post Share on other sites
