Hot End Damage

Post by HDesign » Tue Jan 20, 2015 1:43 pm

When a hot end is damaged due to exceeding 238/240 deg C., what exactly is the damage? Is it the heating components (heating element, temp sensor) or mechanical components? Can anyone shed some light on this. Please be as specific as possible.

Also will the hot end used on the Mini be available and usable on the Taz? What will be involved in the ugrade and at what cost?

Thanks in advance....

The peek isolator inside the hot end can melt. You would need to replace it. Swapping out a hot end for a different one involves firmware changes and sometimes adding a dedicated hot end cooling fan.
