ZT-HE All Metal layer too thin ?

[Orphee]

Hello,

I just bought a ZT-HE All Metal with block insulator kit to replace the Default V2 I had.

I just printed with it the same zcode I already did the the V2, and I have a "little" issue with the result :

The top layer has some holes as you can see on the picture.


The layers does not seems to fix well on top of each other too :


Zcode with Z-suite, the printer is completly stock exept ZT-HE, Filament is black Z-ABS original...
Is there something wrong ?

I thought a a ZT-HE all metal would be better than the stock one for Z-ABS and Z-ULTRAT

Thank you.
Best regards

Thanks for the post.

Lack of reply in 7 months has just saved me $100!

The all-metal version of ZT-HE was developed primarily for those experimenting with materials that require temperatures too high for the stock Zortrax hot end. We use it for Z-ABS as well and haven't had any major issues, but if you're happy with the Zortrax v2, there's no compelling reason to switch, other than perhaps availability of a wider range of nozzles.

The standard ZT-HE with PTFE insert is capable of printing PLA, TPU/TPE, and other low-temp high-friction materials with much better results than the stock hot end.
