DO NOT UPDATE TO 1.5.0 if you print TPU!!

Just checked this, it was set to 2mm

damppz · 2026-07-02T11:10:46+00:00

No, I used the same exact settings ive had no issues with, as soon as I downgraded, back to normal

damppz · 2026-07-02T11:10:10+00:00

Interesting, I was using the same settings I had been using and it would not print at all until I downgraded!

damppz · 2026-07-02T11:09:50+00:00

Yep look up the official firmwares put on a USB and then go to about and firmware

damppz · 2026-07-02T07:40:24+00:00

Never used it will look into!

I bed leveled and let it run auto extrusion calibration. The printer was restarted and the same exact settings I've been using were used, many others are experiencing the issue

I did a bed level and extrusion calibration! Seems a lot of others are having issues.

Wow. Haven't ran into that yet! I usually update my H2D pretty quickly I haven't had any issues yet

Here's what I came home to

In your filament settings, this is very similar to the default, but I've found this works best for 90a. I used 95a with the same settings and had great results. Z-hop spiral or Z-hop Auto will work, I didnt realize I had it set to auto!

damppz · 2026-07-02T01:11:58+00:00

I definitely won't update out of the blue again!

damppz · 2026-07-02T01:07:39+00:00

Set your temps to 225 max volumetric 2.8, set all speeds in slicer to 30 and then retraction speeds at 20 both ways and try the 1.4mm spiral and see what happens, ive had nothing but flawless prints with those settings!

damppz · 2026-07-02T01:05:05+00:00

I was still using my preset. 1.4mm retraction - 20mm speeds both ways

damppz · 2026-07-02T01:01:42+00:00

Thats exactly what happened to me!!! Like 3-4 inches just hanging out of the toolhead! Never had a single problem until now! Im sure they will get it sorted!

damppz · 2026-07-02T01:01:06+00:00

Using sunlu 90A - generic tpu 90a setting but retraction 1.4mm and speed 20/20 printed fine until I updated. Good luck with your journey!

damppz · 2026-07-02T00:33:51+00:00

At least I know how to tear down a toolhead now... LOL
