You’re forgetting that z hops are a thing. Even in a single axis the load from Eg the filament reel depends on the actual weight of the reel, and there’s almost certainly some variation in the cast aluminum frame parts (internal voids are I’m told an inevitable happening in aluminum/metal casting at scale). I assume the input shaping also would be needed on the bed slinger element as well.
As for the bambu, I’m getting voron level performance out of it, though admittedly with a much less open machine. I was using a prusa mini much of the past year but I quickly hit a lot of rigidity issues with its frame that were impossible to address without a total rebuild.
I guess for me the issue is simple: most of the plastics which I want to build stuff with (whether for engineering reasons or haptics of how they flex and feel) really require / benefit from enclosed printing. Pla is an incredibly strong material, but it can’t really handle any flex without brittle failure. And I just don’t like that.
I’m also in the process of putting together a voron v0, which I expect I’ll use even more due to sheer speed and ease of heating.
Nylon and asa and tpu are just so much more gratifying in my use cases.
- Vecr 4y agoWhat do you think about CPE/Chlorinated Polyethylene? Works fine for me on a Prusa i3mk3s in a room heated to 75 degrees F, with limited drafts (make a tent/enclosure if you have to)
- carterschonwald 4y agoI’m not familiar with it! If it’s a fun material great! While the fumes from any filament require serous caution for long term health risks, I’d assume anything with chlorine or fluorine pose some acute health risks? (I make sure I run these machines in a fully ventilated area that is rarely occupied with a person, in my case a spare bathroom )
- cassac 4y agoI built an enclosure for my prusa out of a 20 dollar tub, so I don’t consider an enclosure like a big thing because they are easy to make. If I didn’t bespoke my own I would have made the ikea enclosure. I can print tou all day, you can’t really compare the mini because it’s not direct drive and it’s a Bowden. I bet if you had a proper MK3 you wouldn’t have any issues with your filaments. The mini is the mini for a reason. I want to do asa and nylon but the fumes… eww
- carterschonwald 4y agoVery true! What I was trying to articulate is that a bed slinger motion system requires a much larger enclosure than a core xy motion system or other fixed/z axis bed designs. So that if you have any real estate constraints and want an enclosure, bed slinger becomes non viable. :) I agree that the fumes are bad, I use a spare bathroom with always on ventilation for mine. The unfortunate thing is that the volatilized chemicals/ and particles in pla and petg are also not super great for people, they’re merely less terrible smelling
