Hi,

Not long ago I changed extruder to an Lgx lite (with a Nema 14). And I don’t have to have it well configured…

Since it starts printing well and before finishing the first layer, stop extruding at first a little and then not extrude anything…

I have noticed that the Nema 14, is very hot, reaches 100 degrees, measured with an infrared thermometer, not very precise, I think it is its limit temperature, also suspected that that heat or part of it reaches the filaments, softening it and hindering its extrusion

The first thing I’ve done is lower the current from 0.7 to 0 4. And although it seems to me that it has improved somewhat, it takes longer until it stops extruding, it continues to overheat

The configuration of a driver

[Tmc2209 extruder], can be split multiple contained files connected to the main config.g with include?

Or do they have to be in the same file? (although I don’t know the config.g)
