Basic Information: Printer Model: Ender 5 MCU / Printerboard: SKR mini E3 klippy.log As per previous posts, I am trying to build a MMU. With 5 extruder steppers and a bunch of switches to detect filament position. The coding/scripting proving to be much more difficult than anticipated. I wo…

Unfortunately they weren’t successful in their efforts and pretty much confirms my suspicions that the entire macro chain is evaluated when the first macro is called. I think I can still make my MMU work by using filament switches as the macro essential calls itself. Although I won’t be able to do …

In another thread I see you have implemented a MMU much like I want to. How did you go about doing it? Is it much like I have described above? I will be using 5 extruders. Basically your classic creality style duel driven roller extruders. I was planning on having a servo driven cam shaft that dri…

I have 6 stepper motors, each configured in a typical bowden setup, except these 6 “feeders” all feed into a 6-in-1-out “splitter,” which feeds into a direct-drive setup at the hotend. Each of the feeders is a Klipper “extruder stepper” and the direct-drive extruder is the “extruder.” Before startin…

Thank you for sharing that, I will probably give the freewheeling camshaft a rain check. Gives me confidence to proceed. I have been hovering on buying/building ercf. But they seem to be very sensitive to filament friction which put me off. Would you mind sharing your macros it would undoubtedly sa…

Sorry for the delay, but the reason it’s taken me so long is that my macros are an unholy mess not fit for public consumption, mainly because they include a bunch of bells and whistles that are mostly specific to my setup. I’ll paste some of them below with this important caveat: DO NOT USE THESE M…

Thank you for coming back to me! There is certainly some information to digest there. Would appear to be very thorough! I have a filament cutter on my print head. So I’m hoping that the code I need will be much simpler. I will definitely be referring to this when I get I to the nitty gritty of wr…

[image] frontmandan: I have a filament cutter on my print head. I’m interested in how you implement that. When I first cobbled together my setup I was thinking of trying to include a filament cutter because I was having a really hard time forming the tips of retracted filament so as to preven…
