The old Ender 3 Pro has still got it

[Dutch]

Freshly cleaned and leveled bed and the first layer looks like paper, the only upgrades are a glass bed, EZR extruder and a capricorn bowden tube. Not to shabby for a 5+ year old printer.

My ender 3 is the printer that makes the most reliable and clean layers. Just have trouble with the trianglelabs bl touch. My gantry must be slightly off alignment to be able to have a perfect bed leveling everywhere on the bed. Otherwise the left or right side prints too far or too high

Aka “first layer porn”. Nicely done @Dutch

Got 4 at school and they are azz, I feel like 4/10 prints fail, mostly bed adhesion issues so resolved by a brim usually but still annoying. Walls are also spotty on TPU prints.

What kind of bed do you have? I have glass because I know it's level to start with, then I do the 4 corner level with a post-it note as my gauge. Works for me.

Tpu on bowden is pretty messy. My direct drive fokoos odin is king at printing that. My ender 3 prints petg and pla

Love me some old manual machines... Mine chugs along to this day as well..

Tpu on bowden is pretty messy.

Can that be fixed with settings? I’ve printed 10+ kg of TPU on my Bowden Prusa without much trouble.

Yeah but its a mess. Better print it on direct drive

Why is it a mess though? Is there an inherent issue in the design somewhere?

Like I said, my Bowden printer has no problem with TPU. So it’s not just a Bowden thing.

 

[MrTitanium]

TriangleLabs sells a great gear extruder for TPU. Highly recommend it.

Let me know if you need any help and I'll forward ?'s to someone that has a clue what you talking about.

Pls share TPU Print Settings for your bowden tube Prusa

 

[Camaroboy383]

Creality Bowden feeders need to be modified to print TPU reliably.. prusa already implements that into Thier feeder design..

All you need is a tiny piece of PTFE cut like this ∆ and placed on the output side of the feed gear or gears.. it is usually necessary to drill the feeder assembly to 4mm to accept the PTFE.. after that even a 7 dollar plastic creality feeder will feed tpu...it has nothing to do with settings, just constraining the filament path..

Curious..
What's your print speed and temp settings?
