250 c ABS

[darkjorik]

in Ukraine we have 2 different ABS. Standard ABS , recommended temp 220-230 c.
And engineering ABS recommended temp 240-250 c. engineering ABS little stronger and fragile. + cost little more.
I dont know can I use it or not. I read Rostock Max 2 manual. How I understood extruder can be damage after 245 C temp

The maximum allowed temperature is 247. If you are sure your PEEK fan is operating reliably, you should be able to print in the 240-245 range without a problem, but you might consider upgrading to an all-metal hotend.

Make sure your PID is tuned correctly before you try and push those temperatures.
