Hi,
I control my printer using Marlin firmware.
I have a dual extruder printer if i print using the first extruder (T0) is all right but if i change extruder using gcode (T1) the machine lose position and go crazy(random).
I suppose that the problem is in the gcode_T() function but i don't know where .
Someone who are using this firmware can give me a help?
Thanks

I noted that the Y AXIS don't move and only X axis go left hitting the endstop(I stopped the macchine using Emergystop).
And if i change tool and i do normal movements (XYZ) is all right but if i call G92 E0 the problem start.

are you using dual steppers on your Y axis? Or dual steppers on Z?

Ie trying to use e1 for two things

How about posting your config and some machine details as I suspect its user error, but cant attempt to replicate without your config.
no one else has reported any dual extruder issues...

Hi,
thanks for the answer.
I have a printer with 2 extruder on X axis.
The problem is when the function gcode_G92() call the function sync_plan_position_e(), i tried to remove this call and work.
