X1C printer with 0.6mm print head: I repeatedly get the following error when trying to print saved files. I tried just sending it to printer as Send only, but this did not work either. I cannot print my file. I have changed Bambu Studio Printer Parts to Hardened Steel 0.6mm print head. What else do I have to change? I have been using 0.6mm print head for a few months and this error has only just started happening. Any ideas on how to overcome this error?
I figured it out 
. Turns out I was using an old User Preset. I kept thinking I had chosen the correct User Preset, but I was mistaken. I’m trying to multi-task and failing miserably…

LOL
Sometimes things are too obvious to be seen…
Like when you go for a nice hike through the forest.
All those trees make it impossible to see the forest…
I had you feeling when I tried to print a model I did not use for a long time.
And like you it came with a ‘perfect’ pre-set that always worked fine before…
Took me three failed prints to realise I did not update the AMS info when I loaded the old file…
You are not alone…
