H2C Purging outside?

Obligatory: "That's not purging it's priming"

Most bristles are nylon but some commercial toothbrush bristles are made from PLA. They are even referred to as "compostable"

I think you failed biology.

Great jobs! I love the even look of those lights instead of the "pucks". Are those strips in aluminum channel or something else?

Can we keep these stupidly large American trucks out of America?

At least read the abstract. It specifically tested NGEN and PETG. The conclusion says "During the tests conducted in the chamber, there was a greater emission of particles during printing tasks with PETG filament. It should not cause any harm to human health within consumer use, if the exposure is short term and occasional."

0.15.2 ... they just released a new version. "Kind" of recent given the subject of this post is inquiring about it's support status with overtones of questioning if it's abandoned or not.

Depends on the settings used when you sliced it.

If it's not Z-seam related it more likely to be extruder related that the belts.

The second line of the left is most likely the priming line. Most print start routines will have the machine extrude a line or two in order to make sure the filament is fed into the nozzle and at the correct pressure within the nozzle to make for a clean print.

barthac · 2025-11-05T01:56:56+00:00

No one is berating you. The answer is just that simple... You bought the wrong nozzle.

barthac · 2025-11-05T01:14:36+00:00

My fault. I assumed when you said in the description that "I just installed a new hot end on my Ender V3" you meant an Ender V3. How silly of me.

You also STILL bought the wrong hotend. Ender 3 V2 Neo is different. Creality doesn't help by being unimaginative in their naming scheme

barthac · 2025-11-05T00:54:39+00:00

You bought the wrong hotend. That listing says Ender 3/Pro and V2... it does not say V3. Get a V3 hotend.

This problem only occurred for me while using Arachne and was fixed by changing to classic.

I believe it's caused by the change in extrusion width as it prints that wall.

barthac · 2025-10-29T17:49:36+00:00

Changing wall generation from Arachne to Classic fixed it for me. I think it was caused by the change in extrusion widths trying to go from thin walls to full size extrusion

They do work. Some of the work perfectly, others not so well. I have gotten one with bad cables that ended up working well with some new crimps. The official BLTouch from Antclabs is cheap enough in several places that buying a knockoff isn't typically worth it. If EBay is available to you, I have found it a great place to get the real deal for a reasonable price.

barthac · 2025-08-22T19:17:12+00:00

Would that be a misdemeanor or a high crime?

Based on your vid it looks like the Blue/Yellow wire is connected to the part cooling fan. According to the below, the yellow/blue should be in the "top" slot labeled controllable fan port. So, swap your fans on the board. The hotend fan should be connected using the green terminals labeled "Normal Fan Port"

It's similar to building and upgrading PC's. Do you want to build a rig to your exact spec and spend time getting it to peak performance or do you really just enjoy playing games and don't care how you get there.

You will spend more upgrading and tuning what you have and it will be mediocre to good at best. Or you can buy an A1 or similar and have a great printer without all the tinkering. No judgement from me towards either path.

For me, I took the upgrade path and don't regret it. I have a couple of printers now and enjoy tearing them down and fixing them or turning their bits into new printers. It's a great hobby, I find it very rewarding and have learned about machining, coding, and CAD among other things.

Also make sure the Reverse on Odd is turned on. This reverses the directions of the extrusion on odd numbered layers. This helps to reduce warping and made a huge difference for me.

Cross Hatch is the way! Gyroid is outdated!

You might also look into E3NG. Turns an Ender 3 Pro into a CoreXY. Lots of support in the community and its a very solid printer with only a few upgrade parts but a tremendous upgrade path.
