Hi every one
I have a custom dual nozzle print head . i move one nozzle up and down mechanically by having the head slide againt a bum on the side . similar to the ultimaker 3 or 5. for example T0 is fixed and T1 can move up and down .
to add extra safety i have a switch linked with T1.
what i would like to achieve :
when the printer is powered on the switch is checked and if the T1 tool is down to home X and Y then bring the tool up before homing Z
in this way i can ensure that the printer always start with tool T0
i saw that some people use a variable to save witch tool was last active . but so many things can happen a switch can physically check witch tool is active .
thank you for any info idea you might have
