Hi, You can provide a specific video
Ok I will do that, but for now I have another problem more important. I notice that retractation seems to be a lot slower than my slicer setting 30mm/s, when I look to the extruder while printing it look more like 15 or 10 mm/s, any idea ? (Marlin 2.0)

It is ok !

At first I tried your latest Geeetech Marlin 2.0 release but unfortunatly it was not working better, then I realised that your latest build did not contains the modifications in planner.cpp, so I've integrated the modifications from here (https://github.com/MarlinFirmware/Marli ... 1ec2e75228) and now retraction is as fast as it should.

Also Linear Advance is no more noisy, don't know if it come from the latest "vert" Marlin 2.0 Geeetech release or from the patch in planner.cpp, but now it work silently

It stop at first layer, so very very small, but I can print a 30x30x30 cube without problem, also the extruders stepper drivers are both cold, wich is normal as they stop at start print, it extrude about 50mm and stop for some models, I will try your last build (does it include Mix extruder speed retraction patch ?)

the forum is not the ideal place for discussion the server is very slow and the posting limits prevent discussion suggest using my discord.

Ok I will do that next time, I dont know Discord it will be interresting to discover.

Last post for tonight but important for user facing the same issue : I tried disabling Linear Advance and it works ! (Setting it to 0 does not work, I have disabled it in Configuration_adv.h)
