I guess not that many are using multiple extruders.

Perhaps there is another way to make "End G-Code" conditional as found in https://community.ultimaker.com/topic/21314-possible-to-make-dynamic-gcode-in-cura/ The idea is to define value property in (.def.json) and embed Python expression to be evaluated like in the following example: "machine_end_gcode": { "value": "'G29 P' + str(int(machine_width/25))" }, So in my case, I could pass proper X,Y offset to G1 based on {current_extruder} property. I think it should work...

To fix my problem, one of two things needs to happen: a) Figure out if Cura could invoke "Extruder End G-Code" on the last used extruder. I am sure there is a good reason(s) as to why Cura doesn't do it. b) Figure out how to condition gcode invoked in "End G-Code" section. After much reading, I believe this is currently not possible in Cura.

Dear Cura Users, Please help if you can... **Application Version** Cura 3.6.0 **Platform** Windows 10, 64 bit **Printer** Custom FDM multi-extruder. Four extruders docked on the back wall. **Steps to Reproduce** Print any multi-material model. **Actual Results** Last used "Extruder End G-code" is not executed. Last used extruder remains attached to the tool holder. **Expected results** Last used "Extruder End G-code" should be executed. Last used extruder would be properly docked to its' slot on the back wall. **Additional Information** On T[N] G-code command (where [N] is extruder index), N's "Extruder Start G-code" is executed and that code knows how to navigate to N's tool dock and attach it to the tool holder. At the end of the tool usage, N's "Extruder End G-code" is executed and it knows how to navigate to N's dock and disconnect it from the tool holder. Cura should execute last used "Extruder End G-code", because only that code knows where the last extruder needs to be docked at. I am a aware that Cura always executes "End G-code", but that code can not be conditioned on the docking location of the last used extruder. At least, I am not aware that such conditional statements exist. I am also aware that in multi-extruder case, Cura also assumes T0 to always be the first and will not execute the T0's "Extruder Start G-code", but in that case I can at least inject T0's "Extruder Start G-code" into "Start G-code" knowing it is specific for T0. I don't know why wouldn't it make sense to always execute "Extruder Start G-code" and "Extruder End G-code" even on single extruder printers. Developers could always leave those sections blank if no extruder specific action is required. Thank you and kind regards.
