Why keep the bed heated after initial layer(s) with PLA (or PETG)?

There are three reasons (I can think of): A large problem you'd face with allowing the bed to cool after first layer is you stand the chance of losing adhesion after it cools. When you heat the bed, ...

Printed object is half the height it should be

If the image is suppose to be a 20 mm calibration Cube when it comes out half the height, your problem is the steps per millimeter of the Z-axis, not the extruder. The object you printer is half the ...

What is this white layer on my 3D printer?

My guess is it's damaged print surface from the hot extruder mashing against the print surface. Your description seems to indicate that it isn't a layer.

What is the thickest sensible layer height that an Ender 5 will print at?

Your maximum layer height is related to the nozzle diameter. Typically, a printer is sold with a 0.4 mm nozzle diameter, unless otherwise specified. One expects to be able to print safely to eighty ...

Why won’t this print adhere after a perfect calibration print?

Well I got a perfect print as follows: Loaded the .stl file. Set Cura to use the 'Good' profile downloaded from CHEPCLUB (recommended by a friend). Used Pritt-stick Scotch (glue stick) on the bed. I ...

Why does the first layer only adhere to bed if I increase the temperature by 10 °C and drop the speed by 75 %

Your bed is too low - raise it by turning the knobs underneath. The first layer should not look like strings sitting on the bed as per your photo. Instead it should be a wider strip that looks ...

Why the Ender 5 Pro can't remember the axis position or cant move back to home anymore?

Once you pull the plug or disable power to the stepper motors, the printer forgets its location. That is perfectly normal and exactly how it is supposed to work. The printer knows where the printer ...

How would you clean/prepare a flexible/magnetic mat (e.g. Ender 5) as compared to a glass bed?

I have the WhamBam system which uses a PEX layer over flex steel (which sticks to a magnetic sheet on the printer bed). To clean old material off, I use a "brass sponge" intended for cleaning ...

Why keep the bed heated after initial layer(s) with PLA (or PETG)?

For long prints, if turning off bed heating saves money, throwing out the filament from a detached print costs you more. The risk to gain ratio is very skewed. The “savings” in turning off the bed ...

PETG requires a heated bed otherwise it will shrink, detach from the platform and begin curling at the edges. PLA, however in some situations does not require a heated build platform. It depends on ...

Why would all of the Ender 5 Pro's axis motors (X, Y and Z) stop being able to move (all at once)?

The Creality V1.1.5 board was fried. I replaced it with a BIGTREETECH SKR MINI E3 V2.0 32BIT CONTROLLER. After struggling to find a corresponding firmware for the Ender 5 pro, the axis motors worked ...

Ender 5: Bowden tube shifts in/out of extruder during retractions

Sides without a top will help. Sides with a top will help more. Do you need either? That depends. How warm, how dry, how drafty is your printing room?
