3 x Z-Axis - Idea vs Engineering reality

I use fusion. Thingiverse only accepts stl.
What? You can upload fusion archives. STEP, IGES, whatever you like.

As of december 2019 you can no longer use whatever you like. The formats you mentioned are okay, but solidworks and any other format in their cloud translation thing is not accessible to the personal accounts after the update.

can you look at this

@Garfield You mentioned in one post above that the bed levelling with 3 independent lead screws will be a rarely used feature. Be aware that whenever you cycle power, the steppers will jump to the nearest full step (actually it's worse than that), which could be either forwards or backwards. So you'll need to run bed levelling whenever you cycle power.

All things good to know.
I kind of wish I was aware when I started designing the printer last year - and I'm a fan of E3D - was going to buy a toolchanger machine until it got 'terminated' so you'd think I'd have known about this joint.
I've never uploaded to Thingiverse, I'm rarely a consumer, I am a Fusion subscriber though ( yes I pay for it ).
I've not experienced the Z axis thing on the Prusa but I have seen steppers 'twitch' on startup.
I'm working on something, I'll let the group klnow how (if) it works out.
-
@Garfield what do you mean about the E3D tool changer being 'terminated'?
-
They decided not to go to market - cost constraints or something - I read it in one of their blogs but I'm struggling to find it now.
-
@Garfield they definitely sell it.
It's still closed to people on the original interest list but I think in the next month or so they should have all the back orders complete -
Looks like I may be wrong on this one - found the blog post and it relates to the 'Big Box' ...
But I still don't see anywhere to buy the toolchanger on their site. All that I can find is an opportunity to join the queue, the last update where it was indicated to be 'going into production' was April last year.
Whilst I was interested I never joined the queue and I'm glad that I didn't. I may reconsider if it ever finally appears.

They are getting close to the end of the queue now, so I expect the kit will go on general sale soon. Bear in mind that it is not intended to be a complete printer, more a platform for experimenting with tools.

@Garfield Also take a look at the Jubilee. E3D tool kinematic compatible. Uses a 3 motor kinematic bed. The designer is a graduate student who's studied 'constraint' in machine design... there are many, many, subtle features on this machine...
And, yes, I've built one. So ask any questions.

"more a platform for experimenting with tools."
That's exactly what I was planning - to experiment with tools but my needs for a large format printer exceeded my patience to wait - I have projects parked waiting on a larger print area. When I got into printing it was a means to an end, it was just a tool that has ultimately morphed into other unanticipated interests. I'm actually not interested in multicolor 3D printing - I've no need for it as I don't make ornaments or toys.
My need is forr light CNC, PCB creation and 3D parts / components - to do this all in one package would be utopia but I'll be building a dedicated CNC this year now, I may re-look at the E3D machine again but it won't be this year now.

@Danal : That Jubilee is a nice machine - not sure I like the belts above the frame, I'd be interested to see how cable management is handled
(I'm still struggling with it - it would be nice to supply comms and power to the hot end / tool head and have the brains drive it i.e. no rats nest requiring humungous cable chains or supports)
I do wish that I'd gone down the total DIY route instead of basing on somebody else's kit of parts - I need to consider whether I'm too heavily invested to scrap and start again ...

I.E. tool board. Which is where this discussion started

Cable management for tools.
