What’s the largest part you’ve made with it thus far?by JonathanThompson - Look what I made!
I’ve read this entire thread, and I agree with a lot of what others have said, which are different thoughts than the original poster. First, a little about my background, to set the proper context: In my past, I worked on CNC controller software for Hurco CNC machines. At the lowest level, you can submit CNC Gcodes to the machines and they”ll work accordingly. Even then, they haven’t sold entby JonathanThompson - General
I hate it with a passion as I almost always have a lot of stuff open and running at any given time, and to some degree, we get warnings and can put it off for a certain amount of time: however, the internal IT department forces it on us eventually as a security measure. It's designed by default that people will get updated, because unfortunately, when people are allowed to choose to ignore thingby JonathanThompson - General
QuoteDust QuoteNow it's official: 3D printers are mainstream now! smoking smiley ...time to look for a new hobby winking smiley been thinking that for a while... also you have to be insane to control a printer with windows!

If those tanks were firing at each other, it’d certainly be a more exciting Indy 500! Because of how narrow that trrack is, once one or more tanks were out of the running, they’d need to drive over them for the rest of the laps. Having run on that track a couple times on foot, it looks wider on TV than in person!by JonathanThompson - Look what I made!
QuoteMKSA QuoteBlackgnome Got plenty of steppers/leadscrews/pullys/belts and probe solutions laying around, building a corexy just for fun and to try out diffrent solutions atm and this just got me thinking that 2 should give some extra torque for those Heavy lifting/holding jobbs So it is possible and should not be a problem, will try this to see how it goes. Worst case I´ll just use the goodby JonathanThompson - Mechanics
What’s the reason for wanting one written in JavaScript? That seems like a very impractical solution, unless the input is meant to be fed to a web GL rendering.by JonathanThompson - Experimental
MathewHall has a great point there in shipping: do the shopping, and do the math for the shipping, even if you can get all parts from the same place, are you likely to keep spares for all the types of parts? As for screws and bolts, there likely is a way you can use multiple weaker/smaller ones in the place of a larger one, or, you could overengineer for strength by using all larger ones. Of coby JonathanThompson - General New Machines Topics
One of my long-term 3D printer objectives is to print modular furniture using a large format 3D printer and polypropylene is a material I see as being a workable material for properties. I’m aiming for a 600*600 mm stationary print bed as a result. I’m currently intending to use basalt, as weight isn’t a problem, but rather an asset in the design I have in mind.by JonathanThompson - Developers
QuoteBriztou Hello JonathanThompson, and thank you for your long reply, that will allow me to clarify my post.

As a software engineer myself also with embedded experience I find myself wondering: are you wishing to do all this on your own because of the typical "Oh yeah? I cancdo it better!" common to people writing code to do something that already has other readily available solutions that have been looked at and rejected, or because you don't know what already exists? The thing is, this domain alreadyby JonathanThompson - General
I’m glad to hear that! Now, what other things that are taken for granted in other fields can be found useful for FDMs?by JonathanThompson - General
QuoteLinkreincarnate What about using power line communication? Then you could just have each stepper module plug up to the mains to get power and instructions. No messy wires, easy to setup. Just a thought. While technically possible, and it would reduce reciprocating mass by quite a bit, unless you had all stepper motors physically at the same socket, then you'd still need a stepper contby JonathanThompson - General
In regards to knots: may I suggest borrowing the most important knot in climbing, which is the double figure eight knot? It has these benefits: Easy to tie even with stiff stuff Maintains over 80% of strength of a straight line without knots Gets tighter the more you put strain in it (if you keep falling, you'll have a devil if a time untying yourself) Easy to tie two linesby JonathanThompson - General
I vote for a two-prong approach: 1. Go with your planned high-end machined joints, as expensive as they are: this will set the high-end expectations of what someone can reasonably do with custom machining that doesn't involve a full assembly line. 2. Once that has been done, find a way with design changes to accomplish the same quality results using more 3D-printed parts (likely a number of cby JonathanThompson - Look what I made!
Couldn't the same calibration result be achieved by pushing the motors in question to a known axis limit and then, once that's triggered, push them a bit longer until they error out due to not being able to push farther? I can't say if this was done on IBM PC floppy drives, but the Apple ][ series determined which was track 0 or 35 by deliberately going enough steps to guarantee it'd get to theby JonathanThompson - Mechanics
As I just mentioned in IRC: a funny thought is you could gang 4 of these together to use only 3 motors for the XYZ axes and a separate motor for each extruder, and have 4 things printed simultaneously for minimal costs (Pretty hefty steppers, and of course, if one fails in the middle... well...)by JonathanThompson - Look what I made!
You forgot an advantage in your list: you'll need to stock fewer repair parts! I'm watching this with interest!by JonathanThompson - Look what I made!
