Have you tried 24volt setup? I had the heat issue and went 24 volts and never had any more issue, you need that fan on your hotend to prevent heat Crip and causing filament jamming.by carl1961 - Controllers

Touch screen works fine, it the hotend temptature and no line in the config fig to offset it.i ordered the thermomister at lerdge Ali store.by carl1961 - Controllers
I bought and installed the Lerdge S and replaced the ramps board, My issue is the temperature of the hot end is 70 C to cold so I have to use 275 to print PLA. my other issue I do not like is after it homes Z it goes to X0,Y0 and Z0 left front of bed instead of staying in the center, when it starts to print it drags the hotend across the bed to start printing, so with no extruding going on it isby carl1961 - Controllers
