ULTIMAKER 3 (DUAL EXTRUSION?)

Recommended Posts

Posted · ULTIMAKER 3 (DUAL EXTRUSION?)

The source files will be published like you are used from us, in the future.

About the future, different print cores will certainly be added to the product range that suit a certain type of material or style of printing.

There has been a lot of talk about making the machine smarter and detect errors, both in print and printer, and I guess a sensor could make sense in this regard.

Oef, ..changing print cores automatically.. that sounds like an intense project.

And I am pretty sure @Neotko will come up with some amazing crazy things ;) (and probably a 1.75 mod :p)

I can't go in to too much details as to what will be done in the future. Both because it's not set in stone (and we don't want to raise expectations only to take them away at a later point) and because some of them can be seen as sensitive (and those kind of announcements are best left to marketing & sales)

I don't think that the active levelling can be used to recover print jobs. Or at least not in any sensible fashion.

I'd really like to see some video if the active leveling in action. (If it isn't already out there?)

haha Neotko, 1,75 mm mod, I should have known ;)

Sander, yeah just throwing the weirdest ideas out there to spark ideas from others.

Nallath, I figured (especially the last reason). Nevertheless I still hope the community can give you some new ideas to consider :)

Is there still a downwards homing switch? Then you could home down, and trace the gcode from end to start until you 'home' on your incomplete model. Kinda, hackish, not realiable. Nevermind :p

hmm, maybe i'll make a small vid tomorrow and post it here if that is ok.

Yes there is still a Z switch at the bottom identical to the way the UM2 homes.

I didn't enable the automatic leveling on my machine. I'm very good at manual leveling so I decided to skip it. There are cons to using automatic leveling. For example it is moving the Z motor while printing the first 5 or 10 layers (1mm or so) with less and less compensation as you go. So if you have quite a bit of tilt to your bed it will show up in the final print where the bottom will not be flat but tilted.

So I don't want to use auto leveling to fix a tilt to the bed since I can fix it with the 3 screws but I *do* want to use it to fix any wave-shape to the bed - like if it's saddle shaped or cylindrical. But my understanding (not certain) is that it only does tilt compensation - not 9 point compensation (or more) like some other printers. Delta printers need at least 16 point leveling because of the way errors creep in. UM3 shouldn't need this. I'd rather just bend the entire bed until a straight edge says it is flat.

gr5, so if you print, say a cube, with autoleveling, the square sides wont be square ? Or does the software add some sort of leveling platform before printing ?

BTW, how much tilt can compensate the autoleveling system ?

I don't have exact numbers, but when you first buy the printer, you have to level manually to get rid of any large differences, so the autoleveling is probably just for small warps/tilts (getting the details right).

I think autolevel compensation is just for the new users who doesn't know how to do a proper manual calibration. I also don't like it because I prefer to control what happens on the print.

When you first unbox your Ultimaker, you are expected to do a quick manual level yourself before you start a print. This should eliminate any big offsets in Z. With active leveling enabled the Ultimaker 3 will double check your leveling and compensate for any remaining offset during the first few layers. Where before you could compensate for some of this with a thick and less accurate first layer like 300 micron, your first layer will now be more accurate without over extrusion and excellent bed adhesion.

What sander said. But if the glass is tilted by 0.1mm across the cube you are printing then 5 sides will be square but the 6th side - the bottom will be tilted by that .1mm of error that was compensated for in auto leveling. It's really not a problem since you should have .1mm accuracy across the entire bed with manual leveling and across a small cube the error should be much smaller. But a cube that completely fills the machine would be slightly out.

Anyway I'm happy with my manual leveling techniques and didn't care about auto leveling at the time. I will try it some day. :)

True, I feel like the assisted leveling is already quick, simple, and effective. Plus, I don't have to do it often on the UMO+ (once 1/2 months?). The only case where I would want auto leveling would be if I'm constantly on the go and I need to be able to move a printer a long distance, put it down, and press print.

This feels like an old argument, those that are fine with their manual leveling and those that want everything as simple as possible for the customer. :)

Either way, I am glad it is now part of this printer. Professional users will probably be a lot less technical that we are and appreciate the double-check it offers.

I particularly like that as a user you have the option to decide which way you want to go, and you can decide upon the frequency on which the active leveling happens.

I Like Le Pauls point of view, the boffins will always go forward but other people know matter what there level of expertise will look at the UM3 and other printers and evaluate the machine on its merits and if it has Bed Levelling and it works then its a plus.

Also, if you bed after manual leveling is 0.1mm off, this could make a large print fail. Rather have a failed print or a print that is 0.1mm off in dimensions?

Valid point.

Is there a way to easily remove the inductive probe to make the printhead lighter in case that you don't need it, though? I'm not planning on getting a UM3 but it would be nice to know.

@nerdwarrior: It would really not make a huge difference, the "probe" you possibly could remove is just a small PCB which probably weighs 1 gram or so.

Oh okay, that's good :)

I thought it would be a full blown inductive probe!

It's just that tiny little white PCB.

 

That's nice; might be worth putting one on my UMO+ in the future......

It's on sale if you ask through customer support, right?

That's only half of the story, the sensor board is really just a pcb with copper on it. The new head PCB has the driver chip.
