@tecno In the next version, I will set a button to switch between circle and square. For multi-point leveling, you need to move the nozzle to the designated position first, and then press and hold the button for 3 seconds. There will be a prompt when it succeeds, and the system will automatically record the button xy coordinates

@engikeneer The M83 command is used in the gcode of RRF, which is not 0.01438mm to 0.00005mm. After extruding 0.01438mm, it will extrude 0.00005mm relative to 0.01438mm.
Modifying the speed and acceleration of the extruder is invalid. I have tried it many times.
Running this kind of gcode in marlin firmware will not have this use case, so I think the firmware program may also have bugs.

This is the configuration I used on a large machine, using the stm32 motherboard, and using an external driver

@engikeneer It has nothing to do with the configuration file, gcode parsing problem. You can test the gcode I sent, or modify the filling mode of cura.

@dc42 When the E command is close to 0, the gcode parser should ignore the value of E and only keep the XY parameter, which should solve this problem

@dc42 There is no advance squeeze setting found in my config，So duet officially needs to be tested

After testing, the DUET2 motherboard will not vibrate when the heating is not turned on. When the heating is turned on, it will vibrate even if the set temperature is 0. What I get roughly means that as long as the E extruder is involved, it will vibrate.

Test version 3.3 b1/3.3 b2

I conducted a test, and if the extruder grows close to 0 and there are many cuts nearby, there will be vibration.

E parameters of 2 files are taken out separately for comparison
