Extruder Tool Head v2.1

TAZ6 Single Extruder Tool Head v2.1 which is the tool selection should be entered

I think we need more information. What firmware? If it is the Universal Firmware, that toolhead is the “Standard” one.

Thank you for reply.
the firmware marlinfw.org
Toolhead is for a Taz 6 V2.1
I have installed the latest edition of LE_Cura 4.13.1 and also upgraded to a magnetic bed.
However, when the printer is going through its routine preparation prior to printing, it fails to reach the probes (1)short by 0.5 mm sometimes on the y axis and (2) just short by 3 mm on the x axis of the periphery of the washer.
I would appreciate if you could assist me.
