Same bed, same material, same mesh but always a different first layer

Printer Model

Voron V2.4

Extruder Type

Clockwork 1

Cooling Type

Afterburner

I have a Voron V2.4 here with a Voron Stealthburner toolhead.
First of all, my problem is, why do you have to import the bed mesh manually, why isn't it automatic? He can do the print bed leveling on his own, so why do I have to spend time doing the mesh myself? Is there a way to generate the mesh automatically?

Regardless of the fact that calibrating the printer is more complicated than it should be, the first layer NEVER looks the same.
Sometimes it's perfect, sometimes the hot end is too close to the bed, sometimes the hot end is too far away from the bed.

I always use the same material, the same GCode and the same bed mesh. Does anyone know this problem?

Is this printer even suitable for prototyping or is it more suitable for hobbyists?

What probe are you using? And are you using the physical z endstop?
If you are using physical z endstop OR tap please make sure there are no resedue on the nozzle tip while probing.

I'm not sure what you are asking, but you have these options:
* Run a mesh before each print.
* Run a mesh once, save it under a name and load it in your print_start macro. I have saved different meshes that I load depending on bed temperature. I did them a few month back. Though when I print something big I re-do the mesh before the print.
* Don't do mesh and live with it.

It's a project, takes a while to set everything up but then it should be solid. My first layer are good. I can print PLA, ABS on smooth sheet or textured. All without changing anything by hand.

I use PCB klicky, physical z endstop and auto z script. But tap or klicky as endstop should also work as well.

How do i run a mesh bevor?
I make QUAD_GANTRY_LEVEL bevor each print.

BED_MESH_CALIBRATE

yeah, quant gant is very important. I don't have my PRINT_START in front of me, but from memory I do something like this:

Home
heat bed
QUAD_GANTRY_LEVEL
brush nozzle
home z <- important after QGL
the auto z script <-- of course only do that if you use klipper auto z. Not needed with tap
BED_MESH_CALIBRATE <-- will do the mesh and safe it as default

Thanks for the quick reply!
I will try it.

QGL is not a bed mesh. Run a bed mesh and save it to your config

The official documentation says it would be wiser to mesh before each print instead of a statically saved mesh.

True it is better to do it each time and I use a Beacon and KAMP so it takes less than 30 seconds to mesh it twice.
If you want to save time, save it. If you want to run it each time, add it to the print_start.
