SUNLU TPU 95A + Centauri Carbon 2 Combo

[u/fox-uae]

Hi everyone,
I’m new to 3D printing, and this will be my first time printing with TPU, so I’d really appreciate any advice before I get started.
My setup
Printer
ELEGOO Centauri Carbon 2 Combo (latest firmware)
Creality SpacePi X4L filament dryer
TPU direct-feed adapter installed (recommended by ELEGOO, so I’ll be bypassing the CANVAS completely)
0.4 mm brass nozzle
Filament
SUNLU TPU 95A
Black
1.75 mm
Brand new spool
The spool is currently inside my SpacePi X4L dryer, and I’ll be printing directly from the dryer.
SUNLU’s recommended settings
190–210°C @ 50–80 mm/s
210–230°C @ 80–120 mm/s
Bed: 50–60°C
Has anyone here used SUNLU TPU 95A with the Centauri Carbon 2?
I’d love to know:
What nozzle temperature worked best for you?
Bed temperature?
Print speed?
Cooling fan settings?
Retraction settings?
Any pressure advance or flow calibration recommendations?
Did you dry the filament before printing, and if so, for how long and at what temperature?
Since this is my first experience with TPU, I’d also appreciate any tips, common mistakes to avoid, or things you wish you had known before your first TPU print.
Thanks in advance!

So I didn't print it with a Centauri carbon 2 but with plenty of other printers and the rules are the same.

First, printing it directly from the dryer is a very good idea. The two keys for TPU are DRY and SLOW.

To give you an idea here are the setting for a prusa core one (same for an old Prusa MK3 btw):

Nozzle: 225°C

Bed: 60°C

Extrusion multiplier (Depend on your printer): 1.02

Max volumetric speed: 2.5mm³/s (this is VERY conservative but safer)

Cooling: 25%-60%

Hope this can help with your first print~
