Ah i just post a few minutes brainstorming here to "publish" the invention so it can no longer be patented.
Well in the USA i would have a deadline of 1 year, so investors welcome ;-)
As i own no delta but only three cartesian printers, others are welcome to join the discussion.
The currently canceled was kind of a fraud..
But as the creator intends to do a fourth try i thought that a face-lif

I am backing it because I finally have come up with a concept to turn the SparkMaker into a SMD multilayer PCB maker. And for this i would happily invest $200 and even a resolution of 0.2mm = 200 microns would be all that is needed for that outstanding great use case. With the proper resin even flexible circuits should be possible. The small build size

Thank you ! Last time i assembled a printer was some years ago. First time i see a bowden extruder..
Yes, seller confirmed 0.4mm nozzle.
And i actually had to increase the 89 because extrusion of 200mm only lead to 188mm :-/
I guess it is something mechanical. The Extruder lever moves up and down when the gear-wheel rotates.
And the clicking noise does not come from the filament slipping back bu

Sorry i am very tired now.
This is the config i am currently using for my new coreXY. x_max , y_max , z_min
(the z endstop is on the top and therefore the min because the build plate moves downwards)

Sorry for this simple question..
Have assembled a very nice coreXY printer
Had to modify the home- and max- parameters to get the movements right.
First print was okay but the extruder stepper seems to push to much filament.
It is making this clicking noise when the gear-wheel slips..
When i slow down the printing, the clicking gets less.
Don't know what nozzle size is currently mounted. Reduc

It does not work at all for ABS (without heated bed)
Have put it under my microscope and got the feeling that this is just some sandblasted plastic:
Like you can cheaply buy on ebay: or buy locally.
In my other youtube video , the creators seem to confirm it to be simply some sanded plastic but insist that it is not as bridle as plexiglas, which means "more flexible" ?
Ideas welcome.

nur bis 40°C. Für Drucker mit auto-level geben sie ein kleines abstandsplättchen dazu, das anstelle des fleks aufgelegt werden kann.
Denn mit heissen Extruder sollte man nicht in die Platte fahren.

I have ordered plates for all my 3 printers.
And it is already the second time they are on kickstarter.
Anyone with experience from the first campaign ?
I don't really understand, how a flexible print plate can prevent abs to wrap.

Well i ordered two and chances are high the this campaign will fail completely (as Zano). In last update they proudly announced to have purchased the first component: the filament :-( They are wasting the limited money on a non essential part, even some stuff they can sell with profit when they shut down.
But yes, i got my M3D printer and it nicely prints PLA. But no ABS :-(

Hello Viktor again :-)
I intentionally have set the funding goal to 20.000 Euro because the campaign should only succeed with some hundreds of backers to really kick off the virtual reality community.
I remember "VDX" to have supported some of my crazy ideas here. I know this "too innovative" too well. In 1999 i did program a disco mixing system where music was mixed by emotions.. too innovative

@admin, as there is no off-topic board here, you are free to delete my thread !
When i joined reprap in 2009 i really thought reprap to be one of the most important inventions of the 21 century.
But it turned out that this is rather a narcissistic tinkerer community and innovation is done on kickstarter.
No offense meant, but there should have been a reprap-printer on kickstarter every year sin

Made up a nice concept/invention for these Tiko3d guys Was ment as a gift, told them to put some patents on it (3 days ago - today is Tuesday after Easter), this reprap opensource community is letdown anyway.. And as for sure you will not have the happiness to build on the concept image, do not expect me to post in this thread again.

> As for steel printing. Metal powder and laser beams FTW.
And how do you create metal powder ???
And how much more expensive is a laser beam that can melt the powder in comparisen with an angle grinder ?
First two rules: you do not ask questions.
But also first two rules: you always speak yes.
it won't work with aluminium because it is to soft to be heated up.

Generate extra perimeters when needed: no
solid layers: top 0 , bottom 0
fill density : 0

Only thing left is to generate gcode for a rotating print bed.

Hy guys.
I am currently visiting a friend who is running a robot company fabricating things for the German car industry.
Here we have a huge 7-axis robot which is out of use.
So within 2 days, we want to mount a dremel

yes, too soft pla seems to be causing the trouble.
As i usualy do not heat this room, i built a tent that i heat with a 50 watt tealight.
The pla roll is at the topmost place inside the tent and temperature rises above 30°C.
When the bearing is pressing too hard against the hobbed bolt, the pla might get deformed
and than it no longer fits into the entrance to the hotend.

Hi Nophead, nice you answer me :-)
Yes, that is my extruder, you printed it :-))
I got that ABSPrusa and am that loser who thinks python programmers to be stupid :-/
There are about 5mm space between the hobbed bolt and the entrance to the hotend. And the strong extruder stepper was able to fold the 3mm filament just before the entrance.
Yes, really strange. Otherwise i would not write about i

i don't like these forums, where all the know how gets lost and you better search with google worldwide anyway..
There should be a nice troubleshooting-faq on reprap.org.
With keywords on the parts making trouble and keywords on the problem.
is surely not enough.
I could easily setup such a keyword-faq on my loser-site reprob.org.
But maybe you have a better idea.

the printbed has to go over the cross member threaded rods. If you place the smooth rods below, you will have to add some z-spacers on the linear y-bearings to bring the printbed to exactly the same height as it now already is.

with some try and error it worked with a 112 pulley:
but the 125 pulley that i made exactly like the smaler one is only sliced into big "black" discs:
It is a perfect manifold (strg+shift+alt+M no longer yields any verts)

Only when you have the courage to change everything, different improvements can improve each other and only then can optimization escape a local minima advancing to something worth labeling "next generation".
When printing wires, printing one z-layer after another would be a drawback.
But luckily, the z-axis drive will be like the others, and it the brake is replaced with a long spring to more
