I’ve been following along in the shadows Chris. Now that I have upgraded my technology I can come out into the light and post. Excellent work as usual. -Bob
Congratulations on your new tool I got a similar one - or more correct - I had the same model until they were able to ship the MMU (enables me to use five different plastics / colours etc.) on the same print. I had a few mishaps with mine - one turned out to be a screw that wasn't torqued hard enough, so it came loose and the printing head as well a result This was discovered during the upgrade -> so it worked nicely for some time again (except with flexibles ) until it couldn't be persuaded to load the filaments .... I can for that reason highly recommend that you add an SMD LED on the Filament sensor on top off the printing head, that shows if the sensor thinks that the Filament is loaded - this has shown me a few times that the sensor needs to be adjusted => everything works very nicely again There is a nice little article on how to do so on the Prusa site.Still following your big build Per
Hi ChrisNo it changes between five different Filaments automatically - se the rightmost here :https://www.prusa3d.com/It does mean that it creates a 'Waste Tower' when it changes filament .... in order to purge the printing head.I have just discovered that I can't even find my own posts on the Prusa user forum now But I was also reminded that the Filament sensor isn't the same if you got the MMU or not ....The LED I'm talking about is not really external, as you have to drill a 2mm. hole in the top lid over the printing head, to see it, but it, + a resistor or two, is put on top of the existing PCB, so you get a visible indication of the state that the MCU is reading (but doesn't show - not even LIVE if you ask it to do so in the LCD).
I know it's not an extremely big spanner - but the biggest I have encountered, was in my youth.

My late father was a bulldozer driver, big CATS - D8s & D9s, and I used to go to work with him in the school holidays. I remember holding his hip as we both jumped off the track onto a one inch diameter tommy bar some six feet long to remove the nuts on the rear drive sprocket!
