As a videographer and reprap enthusiast I have been thinking about this for a while. "A glidecam is a hand held camera stabilizer, which, through a 3 axis gimbal and a counter weight system, separates the movements of the camera operator from those of the camera, providing smoother motion for the viewer." The Kontinuum Glide is all that, AND you can make it on your 3D printer. I made one for myby KontinuumReprap - Look what I made!

Ok, I have to admit I'm kinda lost here. I still don't have the Ramps hooked up, so it's all theory for now, but I would like to inform myself a little more before I start experimenting with stepper motors. Question: How much of the section containing the " WRITE(Y_DIR_PIN" etc do I have to copy with the "E1_DIR_PIN" adaptations? And where do I put the repeated section? Here is the section fby KontinuumReprap - Firmware - mainstream and related support
Thank you SO much. That was really helpful.by KontinuumReprap - General New Machines Topics
@Andrew Thanks a lot. I had a look inside the stepper.cpp file, and there are only two occurences of each command. It seems like exactly the kind of solution I was looking for - Almost too easy to be true, hehe. Is that really all that's needed ? I will do some testing over the coming days and see what I get out of this. @Traumflug I think I see what you are saying.

Hi reprappers. We are building the Kontinuum Reprap, which is basically a reeeeeally big 3d-printer, and it will have a rather heavy y-axis to move around. We will run the printer off a RAMPS 1.4, and we are hoping to use the fifth motor output that this board has to run an extra stepper for the y-axis movement. We have two beefy NEMA23 steppers and the idea is that if we run them on separate cby KontinuumReprap - Firmware - mainstream and related support
Hi Andrew. Thanks a bunch. Those are all excellent ideas, but we will definitely try to go with the firmware hack. Most important reason being that it doesn't require any soldering (a horrible process which lacks even the most basic "undo" functionality) We will move this discussion over to the firmware forum. Thanks for your input. Jeppe Kontinuum Printsby KontinuumReprap - RAMPS Electronics
Thanks jcabrer. That was of course our first thought, but we're afraid that it won't cut it for what we're putting together. The y axis will be quite heavy, and will be pulled by 2 NEMA23 steppers. We will be making really large prints that will have the motors working constantly for long periods of time. We were hoping to be able to split the load up between two controllers to not over-heat anytby KontinuumReprap - RAMPS Electronics
So, we are building this large Reprap and we want to use nichrome wire to heat it's 100 x 100 centimeter print surface. However, we have a problem calculating what size nichrome wire we need. The calculator on this site (http://www.jacobs-online.biz/nichrome/NichromeCalc.html) generally seems really helpful but it only goes to 90 centimeters in length and that will obviously not be enough for us.by KontinuumReprap - General New Machines Topics

Thank you guys! This is some great input, which has given us a lot of food for thought. Our conclusions for now are the following. - Print the whole thing in PLA. We were already thinking about this, but didn't know if it would be a suitable material for the wheels and base. Now it looks like it's really the only option - Which is fine by us, for the obvious environmental reasons, and the loweby KontinuumReprap - General New Machines Topics
Hi Viktor, thanks for your input. Could you please specify what you mean by "special layer design"? Sounds interesting.... Any other hacks you might have that could help us out are also welcome. I know that large prints can be problematic, but I think that we can make it work. First of all, almost all the really big prints are only around 3-6 cm tall, so that's not really very much.

Hi fellow Reprappers. We are building a laaaa-a-a-rge reprap 3d-printer. Our main focus is to make a printer capable of printing the "Kontinuum Garden". The garden is a crowdfunded open-source 3d-printable rotating hydroponics system. Follow the link to learn more. We're publishing the parts on thingiverse as we go along. You can download your own 3d-printable garden here :-) (Uploaded the raby KontinuumReprap - General New Machines Topics
Hi again. Turns out the whole problem probably boiled down to working too late at night or maybe just being plain stupid. When I went back to the cables and started testing them again, I quickly found a good combination. Yipeee! I guess there might have been other factors at play too, but really, stupid and sleepy sounds more likely... The cables are now lined up blue, yellow, green, red, lookby KontinuumReprap - Sanguino(lolu)
Still no progress here. Maybe I should try to run two power cables from the power supply. . . ? It shouldn't be necessary though. I haven't even connected the heated platform yet. The power supply is a 650W atx-2 power supply with four 12V 18A connections. I'm using yellow (12V) and black (ground) from the 24-pin connector, and connecting them to the board via screw terminal. The steppers areby KontinuumReprap - Sanguino(lolu)
Thanks for the feedback nophead. I checked (and in some cases, rechecked) the things you mentioned. - Motor wiring. I tried all 24 mathematically possible combinations (the motor cables are red, green, blue and yellow), and the motor acts EXACTLY the same no matter what I do. Isn't that weird? Shouldn't some combinations of cables give no result at all?? - Current too low. I guess you mean theby KontinuumReprap - Sanguino(lolu)
Update 2: I just found this Sanguinololu from a vendor in the UK. Looking at the photo it clearly does have something soldered into the spot where mine doesn't... Can anyone tell me what this piece is? (circled in green) Could it be responsible for the symptoms I described? Thanks :-)by KontinuumReprap - Sanguino(lolu)
Update: Here is a photo of the rear of my sanguinololu. 1 As you can see there is an empty spot, which didn't come up on the wiki about soldering the board. Of the original electronics kit, there are 3 10k resistors left. Maybe one of them goes here?? 2 The terrible mess in the upper right hand corner is due to desoldering. I ran out of pins, and needed these for the motors... I've checked thiby KontinuumReprap - Sanguino(lolu)
Hello reprappers. I am building my first 3D-printer. It's a Prusa Mendel, and it's basically all assembled (except for the heated platform) However, now I'm hopelessly stuck with steppers that just judder. The electronics (Sanguinololu 1.3a) came with the ftdi pre-soldered, and I did the rest myself (another first) So it's all connected. 12V to the Sanguinololu.
