  1. Cool, thanks for your time. But guess what, I worked it out. As you can can change material during a print, ie if you run out of material. As I have been using a generic wood base material recently it has jammed a couple of times, otherwise like you the only other material I’ve similar problems to is the natural PVA. Anyway what I worked out is if you select change material, then go through the process of unloading, reloading etc. Once the material is unloaded you can remove the the Bowden tube, then ”Pretend” to load new material. When the printer is waiting for you to confirm ‘extrusion is flowing freely’ you can get some PLA material and proceed with a hot pull. What I found though was I had to repeat this procedure about 3 times before I could get the material flowing freely, (as the system times out after a couple of minutes), then whoa behold material flowed freely, i reattached the Bowden tube, reloaded the material properly and continued print as normal. Seemed to work like a charm. Just a note when I was on the ‘confirm extrusion is flowing freely’ step, I would put the PLA material in for a few seconds, pull it out cut the dirty tip off, reinsert and repeat constantly using pliers and apply slight pressure. Hope this can help any others out experiencing the same problem.
  2. Thanks for the reply, couldn’t access any changes to print core temps while job was in progress. Had to abort and start again… 19hours😥. Oh well. 🤷‍♂️
  3. Hi, Just wondering if there is a way to clean a print core during the middle of a print. I’ve tried reloading, however once the material loads, it fails to extrude during the load process. When I try selecting print core clean it is greyed out (unselectable). Do I have to abort and start the job again, or is there a way to clean print core without aborting. Thanks
