Again, thank you Meduza. Very informative and helpful, much appreciated.
I almost never print PLA anyway, mostly ABS, nylon, Carbon Fibre, etc. But want to try some of the higher temp materials. Which parts would i have to replace in order to print 290? Could i replace the first section of bowden with a PEET part and replace the teflon, etc with aluminium or steel? Would i have to introduce water cooling or a heatsink in that case? I'm already working on my own nozzle designs, to replace the ones i got with Ollssen Kit upgrade, so might as well go full monty on the whole hotend then?
