Hello, i don’t know how if it’s available the working firmware for 3dTouch and filament change for the KP3S Pro 3d printer officially made for you and a detailed tutorial/guide to do this procedure in home.

Hello, we have set up printer. It turned on fine, we started our first print.
Then after about an hour, halfway through the print, all of a sudden in the middle of the print, it just stopped. They waited a while and then finally turned it off and back on. The screen said LOADING for a long while, and then flashed to the normal info screen for a split second, and then went blank. This was repeated 3x now with same result. If just says loading for the longest time, flashes to the normal screen, and then goes blank. We have unplugged and plugged back in as many connections as we can find. We have also reformatted the flash drive that came with the printer. What do I do next? The screen just goes to blank every time if flash drive is plugged in or not.

@Frustraded User works. But after about 1 hour of printing, the printer beeeeps and restarts. I am frustrated too.

Hi folks,
I just bought a KP3S PRO, so I’m new to this.
Can someone tell me where to find the latest firmwares please ?
Is there a version that supports 3D and/or Laser printing using an additional Laserhead ?
Your reaction will be highly appreciated, thanks,

Прошил v1.01.0712.22-20230411T055011Z-001 в KP3S PRO, однако как и раньше, при печати обороты вентилятора обдува сопла показывает только 0 и 100%, промежуточные значения не показывает!

All sorted now. Had to use a micro SD card less than 8gb e.g. 4gb

I’ve just flashed this on my pro s1 it works but the button icons are missing and there is just text boxes. Does anyone know how to fix this bit ?
Thank yoo

Works with KP3S Pro S1. The major issue I have is that firmware ignores INVERT_Y_DIR setting in configuration file. To invert motor direction I had to change pins on motor cable.
