New MKS TFT28 V4.0 for LCD replacement - leveling issue.

kureka

Hi..All,
Currently i replace my LCD MKS TFT28 V3.0 to V4.0..(because the old LCD was broken). Unfortunately during first time leveling the nozzle not goes to 4 corners as usual for A5 heat bed size but just move 4 corners 150mm square only. Can anybody help and guide me how to setting the size of leveling for A5?
- Just newbie in 3D printing world. Thanks.

look in the mks_config.txt file when flashing:

#the point number of manual leveling:(3,4,5 point available)

>cfg_point_number:5

#the coordinates of 5 point on manual leveling

>cfg_point1:50,265

>cfg_point2:265,265

>cfg_point3:265,50

>cfg_point4:50,50

>cfg_point5:152,152

Thanks my friend for the advices...btw my new MKS LCD was Version 4.0, can i updated with MKS LCD firmware version 3.0 thats available in this forum, is it compatible? I founded version 3 only in this forum..thanks.

I would venture a guess that it would be compatible. Did you throw away your old LCD? If you didn't take a picture of each of the main micro controllers and compare model numbers. If they are the same (I would think they should be...) I would try the community firmware.

Found a youtube video of someone putting the TFT on an ender3 with a MKS Gen L:
Just make sure you leave the baud rate at 4. Our printers use a 250000 bit/s rate.
