Hello,

I did some tests and the print quality of the print is actually really good but i still have the Z scar or seam on the outside of my cylinder type object.

i use this:

*Latest Version Cura
*Colorfabb PLA Black
*Nozzle Stock TAZ 6 nozzle 0.50
*Layer Height of 0.15
*Print Temp. 210
*Bed Temp. 55~60
*Print Speed 60m/s

Now ive got 4 things i want to know or solve and i hope one of you can help me a bit.

1* When the printer start printing it drops a blob where it needs to print later on, and ruins my prints because all the mess stick at the nozzle when the nozzle runs over the blob and drags it to my actual print. --> abort print.
i think i have found the issue in Cura it’s called Enable Prime Blob correct me if im wrong please :slight_smile:
I’m also placing skirts to have a perfect first layer.

2* as mentioned i still have the Z-scar.
i know it’s something that cannot be completely removed bu i think my prints show it too much.
i found this setting in latest cura version TAB> Shell. called:

Z-seam alignment: you can choose, Random > User Specified > Shortest. Standard setting in Cura is Shortest i set it to random?
Z-seam X 140
Z-seam Y 840
Ignore small Z gaps, ive checked the info box next to it but for me it’s not clear what it means, do i need to enable or disable it, it’s enabled in standard cura settings :slight_smile:

3* Can i go to a lower layer height with this printer > nozzle combo. i want to print small pieces like 30x7x7mm and i have the 0.35 nozzle here new in box. but i aslo print cylinders which are 12cm long what is best to use for what ? Will my 0.35 nozzle takes ages to finish a cylinder of 12cm long ?

4* look at my picture in the attachment, the bottom of the object i want it to be a bit cleaner but i think i still need to use blue painters tape regardless the PEI sheet of my TAZ 6?

i have also added my .gcode of the printed part in attachments.

I’m happy the printing goes better and better.

Thanks all !

Hi

The only time I ever see artifacts that look like loops is

if the model is not solid.

I use an older version of CURA so I can’t comment on your other troubles.

I also use a TAZ6 machine.
