Loading low temp filament
I always unload my filament when done printing to prevent filament from getting wet and breaking in the PTFE.
When loading a low-temp filament into extruder that had a high temp filament say from PC to ABS The PLA cant push thru.
I load the PLA as ABS then unload and reload as PLA. Is there a way to load without going thru this cycle?
The general advice is always to load at the higher temperature and purge out any filament residue.
A method which I repeatedly resolve to adopt but inevitably forget is:
When unloading high temperature filament always reload PLA scrap at the high temperature then unload again. In theory it always leaves the printer in a ready-for-any-filament condition - it works - if only I remembered to do it every time.
Cheerio,
