Hi Julia,
Nothing is wrong; just wondering about the expected life of the PTFE tube at max rated temps or a little above.
My Z-Temp HE is printing fine using various PLAs, UltraT, Z-ABS, etc. However, my readings say the Zortrax M200 prints UltraT at ~260℃, Z-ABS at closer to 275℃ with thermal overruns even higher.
I now have a reason to print quite a bit of Z-ABS:
a. In rough terms, what has your experience been regarding the life of the PTFE tube at those temps?
b. What are the symptoms when the PTFE has seriously degraded?
Tnx,
Jeff
