I know Repetier can have 5 extruders, I don't know anything about programming them as axis.
Also looks like aprinter can add axis "easily."
Sounds interesting! Thank you for the hint, I will have a look at aprinter, too!
I have heard that Teacup is also on the way towards 5 axes support. It seems that there is already some development going in the right direction.

If you look at the most recent commits to Teacup firmwares' experimental branch, you'll see a number of changes towards supporting an arbitrary number of axes. You're welcome to fill in the missing bits, I'll happily give you commit access.
Wow, that is great ! I will have a look at it!

@A2: these are nice examples!
I would love to see an open source 5 axes waterjet cutter! This would be an awesome project!

Hi,
I wanted to ask if you know any firmware that can handle 5 axes (at least more than the usual 3 axes in our 3d printers).
I would love to establish 5 axes 3d printing, to allow more than 45 degrees of overhang. I have already a proof of concept that shows the possibilities and I would love to develop a 5 axes 3d printer.
Thank you for your help.

Hi Thorp,

Wonderful work Fabricate!
You have demonstrated value in a 4, 5, or 6 degree of freedom head. More significantly, you have a proof of concept that actually works. You have been able to circumvent the '5DOF slicer problem' in your proof of concept by simply manually writing the gcode. Well done!
Thank you!

Don't forget you now have the potential to collide the head with previously printed material ... hasn't the definition of "printable" just got a lot more complicated?
Good stuff though!

Wahou ! That s Nice ! How do you manage the fourth axis in the firmware ?
Thank you! At the moment it is just a proof of concept so I have hacked marlin to control the fourth axis. Unfortuantely I did it wrong so the tilting is executed a bit too early.
If you know a 5 axis firmware, this would be great. Otherwise I will start to implement it correct in Teacup (or maybe Repetie

The slicer is only in the geometry acquisition stage right now. It will accept two main parameters: max angle of nozzle relative to the print surface normal and max angle of nozzle relative to the bed normal. I don't know if it will be generalized to deal with 4D pr

Ich habe in der Zwischenzeit eine 4te Achse für einen Prusa Mendel gebaut und konnte damit in einem ersten Test 80 Grad Overhangs drucken. Jetzt bin ich gerade dabei, die 90 Grad zu knacken ! Die Ergebnisse hab ich im englischsprachigen Forum gepostet.

The perimeters could be slice in seperation similar to sparce infill, with infill being sliced as a somewhat seperate entity, filling based upon shape rather than perimeter layer.
Yea, this is a good idea (and will speed up printing time). So the perimeters should be sliced by the shape of the object and the infill by constant z-layers.
But what if we can really print 90 degree

@Fabricate: Awesome! I have a student working on a 5DOF slicer or more specifically a non-planar slicer to be used with the Sextupteron.
On a side note: I am contemplating making a program that will take an STL and perform a transformation so that it can be used with standard slicers. (Essentially, it would make the nonplanar layers planar.) The program would need a second

In college I started with punch cards, then paper tape, then programming gcode-mcode on a console, so I appreciate the effort that you have put into your project. Hopefully one of the slicer gurus will find interest in your endeavor, and sort it out!
Yea, I hope so, too! But there has to be a good theoretical foundation, as you

And the software - both the firmware and the slicer.
Well, it is just a proof of concept at the moment. There is no slicer (at least I could not find one) so I am writing the code for test objects by hand. And the

Could you somehow make use of the M400 command to wait for buffer to clear? Or maybe the G4 command would serve. The G Code reference at this wiki suggests that "G4 P0" is equivalent to M400, so it might be an alternative if your firmware does not support M400.
Thanks, this is a great solution ! I will try that.

Hi,
for my 4 axis printer I hacked Marlin and added a new M command (just like setting the fan-speed, i am setting the angle of the new axis). This works very nice, but the problem is that in a G-Code file the command gets executed about 2 layers ahead. I guess that this might be because of the lookahead for circles, but I don't know how to deal with that. Can someone point me into a direction w

Hi!
I made a fourth axis upgrade for my prusa mendel i2 and in a first test I was able to get 80 degrees of overhang. I am using a 0.9 mm nozzle, extruding 1mm wide and 0.75mm high layers.
In the first part of the test object I was tilting the nozzle to about 20 degrees and printed 40 degrees of overhang. In the second part I tilted the nozzle to about 40 degrees and was able to achieve 80 degr

@bobc: Ok, then I am going to try option 2 when it comes to testing servos.
@Gordie: I heard once that using a dual motor setup for one axis and microstepping is not a good idea, but I am not sure if this is also true for a dual motor + dual driver setup. Read more about this issue here.

I am interested in powering servos from the RAMPS-FD, but I did not take the 3.3V logic level into accout. So I am wondering if it is a good idea to run them directly from the RAMPS-FD. I am looking forward to your results with servos!
I read once that it is advised to have a separate power supply for the servos (I think they can draw a lot of current in a very short moment). Moreover they can b

We are actually developing a 5axis 3D printer that solves a lot of the issues that you're referring to. The most difficult part of the build was figuring out how to feed the filament with all the ranges of movement.
It is nice to hear that someone else is also working on a 5 DOF printer! I would like to have a look at your printer design. Do you have a project-website or a gith

We're doubling up the wires to let us pass more current. That slip ring has 12 connections total, so we can use 5 for each connection on the heater and the other 2 for the thermistor. This brings the limit up to 10A (120W). The slip ring hasn't melted yet, so it seems to be working.
Nice to hear that it is working at such a high current! I did not expect that. There is also a

Bei deiner Variante hast du ja nur einen Tisch der sich dreht, Düse die ich in X Richtung bewegt, eine X Achse und die Z Achse. Der Tisch steht dabei immer in Waage
Bei 5 Achsen hast du ja X und Y am Druckkopf, Z Achse sowie 2 Achsen die den Tisch Schwenken und Drehen (Glaub C1 und C2, hab aber noch nie an einer 5 Achsen Maschine gearbeitet..)

Also von der Hardware Seite sollte das ganze machbar sein (Wenn du es über einen Servo neigen willst, dann sowieso).
Perfekt, das klingt sehr gut!

Schwieriger wirds wenn du das ganze als 5-Achs Version machen möchtest, da musst du ein Rumba nehmen, das hat Platz für 6 Achsen.

Hallo Viktor,

Ich denke, daß der Normalenvektor aus der Verbindungsreihenfolge der drei Punktkoordinaten einer Facette bestimmt wird - das sollte also eindeutig sein ...
nicht nur das - er wird direkt für jede Facette mit angegeben, z.B. hier in negativer y-Richtung:
facet normal 0 -1 0
outer loop
vertex -1.0874 5.9 0
vertex -1.0874 5.9 5

Computing power does not seem to be an issue (yet). As it turns out, the trig functions provided by avr-libc are extremely fast. We ran a test and found that tan() executes in about 13 cycles. An examination of the source code shows that this is because they are using some hand optimized assembly and lookup tables.
Very nice to hear that! Also the results on your printer look

That's an interesting project!
You can get little RF modules which might be useful. The comms protocol could be quite simple, you just need to set and read temperature. I think you could use a small board like a sanguinololu to build a prototype, although you wouldn't need all the features on there.
That is a nice and quite simple but powerful solution!

If the micro had more interesting processing to do it would make more sense, but using firmware to do a low level processing job is an unnecessary complication. One thing a micro could do is to manage set temperatures, but that is such a trivial task it is hardly worth offloading. What would be useful to offload is driving the steppers, but that is the hardest function to divide up and
