Unless you enclose the printer fully in some way or another, I see problems, even beyond just print quality: humidity can and will end inside the printer by condensation and destroy the electronics, especially in the fall and winter months. being accessible, children from the neighborhood might get their stubby fingers into the running machine or throw off ...

It seems the pinout scheme changed on the Creality board between the versions V4.2.2 and 4.2.8. For example, PB9 & PC2 were inverted between step_pin and dir_pin. Using the following Klipper config (found here) allows the motors to do their job again. [stepper_x] step_pin: PB9 dir_pin: PC2 enable_pin: !PC3 step_distance: .0125 endstop_pin: ^PA5 ...

If you want a single word answer, then no. Before you ask this question you need to figure out why your prints are slower than you want them to be. With default settings, unless your models are something dead simple like a big cube or cylinder, you're almost certainly limited by acceleration, not extrusion rate or even max print/travel speed (which you'll ...

The density of the filament can be specified in the material model of the filament in Cura (Preferences -> Configure Cura... -> Materials and click on the material/filament you are using to slice your model for PETG), look at the value behind Density, the PETG filament I use is using 1.28 g/cm³ (PETG Economy Black -> Specification >). This field ...

For anyone who has this problem in the future my solution was to loosen the screw on top of the touch just a little bit

This sounds like nothing but a bed leveling (distance from nozzle to bed) problem, though you may have introduced other problems disassembling the hotend. It's normal to have material oozing and bunching up before the print starts; this is why you start printing with a priming line or skirt. Clean the bed well with isopropyl alcohol, level it (paper method ...

Likely underextrusion. The Ender 3's extruder is particularly bad at PETG and slips a lot unless you go really slow, like 3 mm³/s (about 40 mm/s at 0.2 mm layers and 0.4 mm line width) or lower. For a long time I thought this was a limitation of the material, at least without a really powerful hotend, and wondered why anyone liked it. But after replacing the ...

There could be multiple reasons for this happening, the most probable cause would be that the bed isn't leveled properly, if you have an auto leveling bed I'd suggest that you give that a run through, I also found it personally helpful with mine (Ender 5 Plus) that if I did the manual leveling, so the four corners, then go and do the auto leveling. Another ...

I figured this out... It was a firmware issue. I went to Creality's Forums and found the appropriate firmware and now it auto homes as I would expect it should.

A quick solution is obtaining a pre configured configuration file for this custom extended version of the Ender 3. While it should be very easy to find configurations for Ender 3 with or without BLTouch, the only difference this extension has is an updated printer volume specification. A ready made configuration is found here (please note that it contains an ...

I had the exact same issue and then suddenly it went away. The only thing I had changed was my Z-offset. I moved it away from the plate by roughly 0.1 mm. To confirm it was the reason I set it back closer to the plate and the problem came back. I think When the nozzle is too close to the plate the plastic cannot freely flow out and hence the pressure ...

Maybe an adhesion issue. I use 320 wet/dry paper on my mats when they fail to work. Just circular motions.. Clean well with Windex or alcohol.

You should be able to add a global override to the flow percentage on Marlin firmware printers. Add this line somewhere in your start code: M221 S97 ; Flow Percentage hard set. In Cura, edit the printer's machine settings. The S is the percentage. In my case, 97 % works for PLA+. Here is a link you might find useful. Marlin Docs
