I personally have not tried a Mk Swiss nozzle as I just use the stock one. As of yet I have not found a fix for the second extruder which is frustrating because I got this printer for the dual extrusion capability. With your nozzle issues the Swiss nozzle might not have the same threads as the printer does. I have noticed after checking the wire holder bolts that they use an odd form of measurement so that may be the issue.

The unit of measurement is SAE / imperial. SAE stands for society of automotive engineers. Thats the unit of measurement on the wire bolts so it may be the same for the nozzle threads.
I have leveled the bed perfectly and I hear the clicking but it won’t extrude when it starts printing but I can load the filament easily.
Turns out the one of the stepper motor wires broke. After replacing it I was able to get perfect prints. A quick question though. My rafts are sticking a bit too well to the prints. I can get them off but with a lot leftover thus requiring me to use a razor to pick it off, any tips?
Again, that sounds like the nozzle is to close to the bed. The clicking is the extruder skipping which basically means something is restricting the filament from being able to extrude. So, if it extrudes ok when loading but stops when trying to print there are only a few things it can be.
Nozzle to close to the bed.
Temp not high enough for the filament and the speed.
Some other obstruction or binding.
Level the bed and then lower it away from the nozzle a bit so there is a bit of space and then see what happens.
Also what are the settings for the first layer plus temps etc.?
Another thing is make sure there is nothing binding the filament as the gantry moves. Possible for it to get pinched.
This is not uncommon. The barrel gets a “notch” in it from the screw and that hangs on the bore. I have one that is so stuck I will have to drive it out with a punch.
