Hello Guys, Hope any of you can help me with my dilemma. 3 weeks ao I got my first 3D printer an Ender 3 V2. It prints PLA very well and I can print small parts on TPU BUT when all turns complicated and bad when I try to print medum sizes TPU parts such as the GoPro mounts. I'm using Sain Smart TPU filaments. I'm also using Cura 4.8 and retractions enabled. Temp 195 to 200 and bed 50. infill 65%

This has been very frustrating after so many hours, attempts and money wasted.

I have tried so many different settings to no avail.
Could anyone please provide some advise?
Please see picture attached.

Thanks very much guys

Have you tried the SainSmart TPU Cura Profile for the Creality Ender 3 V2? If not then I would start with that. You can find it on the SainSmart website at the link below.

Using the Cura profile suggested is a good place to start as SnowLeopardFPV has suggested. in general when printing TPU you are going to want to turn off retraction, increase your flow rate (110% would be a good place to start), slow your print speed to 30mm/s max. What size nozzle are you using?

Did the print break at the back after printing? or did it print like that?
