Had a little problem but not with the printer!
It was a slicing software issue. But had great tech support from Asta. Thanks again.
Fred From Texas appreciates the customer service

Works really good for having no idea what I am doing!

Longer LK4 X is my fourth 3D printer. Amongst my Creality Ender 3, Anycubic Mega i3 and Anycubic Mega Zero, LK4 X is the best so far, and not even the most expensive one.

With magnetic bed, direct dual drive extruder, 3D Touch, silent drivers, Z screw top fixation, X & Y belt easy tensioning system, filament runout sensor, double blower cooling system, optical Z endstop and sensible cable management, there is really not much left to be desired.

The only thing I couldn't help regarding hardware was removing the extruder cover - that big piece of metal was only a dead weight for X axis motor. I also tried to speed up the mesh bed leveling with G-code, but with no significant improvement yet. Regarding firmware, I would really appriciate if Longer published the source codes for further tinkering - given that main board firmware is open-source Marlin, it shouldn't be a problem. Also having access to LCD firmware would be greatly appriciated - I really miss seeing a remaining print time estimate, and I would gladly translate the controls to CZ, SK and PL.

Facile monter et une bonne prise en main

The base is not aligned anymore, even after manual and automatic calibration. Their support team sent me a video to do this but it didn't fix it. I stopped using it

This is my first 3D printer and it has been a great experience. It was easy to set up, mostly easy to balance, very easy to use and works great!

I great 3D printer for the money packed with lots of interesting features and almost ready to go out of the box with not much tuning needed.

I love and i want it

adorava ter esta para dar vida aos meus projetos!

gostava de ter a LK5 PRO FDM 3D Printer para poder imprimir bonecos para o meu sobrinho ;)
