I printed with grey Z-ABS and the Z-Suite v1.6.1 and with the firmware 1.0.3. I used the ZT-HE nozzle. Other prints have the same issue. I will go back to firmware 0.0.8 and an older Z-Suite version and make some test. On the zortrax website only the oldes version you can get there is 1.3.0! Someone have an older version (e.g. v1.2.1) and can give me that z-suite version? I can send that person my e-mail address in private message, so you can give me the z-suite in the e-mail attachment.
