QuoteMrMeeeseeeks Quoten8bot Interesting. The main problem is that there is no software to control this. Also, what would be the advantage for the added complexity? The software would be a challenge. It would be interesting peice of code. As for Advantages? Speed is the main idea. You could have the base plate move the left as the delta moves to the right, that kind of concept.

An uncoordinated move is one where each axis is moved at top speed to the position required. This means, on a cartesian, that the Z will move much slower, and the x/y either the same, or at different speeds depending on the moving bed situation. On a delta (and likely other motion systems) this causes each axis to move without regard for where the nozzle should travel through during its move. Inby n8bot - Delta Machines
I agree with you here. Manual calibration seems perfectly fine, and once calibrated remains constant for months... I don't understand autocal, let alone calibrating before each print.by n8bot - Delta Machines
The limitations of buildtak are that the surface is very delicate and the sheet will peel up during the first large ABS print that would otherwise normally curl up.by n8bot - Reprappers
I would say it's definitely more adhesion than with tape. It's only marginally better than tape, though. If you really wanna upgrade, look at a nice thick PEI sheet. If you get the 1/8" thickness, you don't need to glue it down to anything, just clamp it to your glass/flat bed.by n8bot - Reprappers
Any photos of your setup, or specifics about rod length, tower spacing, and bed diameter?by n8bot - Delta Machines
Photoshop can extrude from a PNG. What is transparent is nothing, what is colour is solid. It's simple but works for 2d extrusion. Lithophane generators or the like work well, and Cura can slice directly from an image file -- at least JPG and BMP.by n8bot - Reprappers

No clue about that one, sorry. I use fusion360 for designing and it works out great.by n8bot - Reprappers
You are exactly right about the loose points. I'm speaking even after accounting for these effects, there is a spring effect to the bowden system. This is really unavoidable, as the tube needs to be flexible and the diameter of the filament cannot be exactly the same as the bowden tube or it would bind. I'm even running a 1.8mm ID bowden tube, which is quite tight and requires a geared stepper toby n8bot - Delta Machines
Be careful with too much retraction, as if your hot-end is not optimal, or has a very short transition between hot and cold, you can cause jams by having too long of a retract. This can be hidden until you print gcode with many retractions in a small timeframe. I find that there are ways of combating the drawbacks of a bowden setup with slicer settings, like the coast and wipe functions of simplby n8bot - Delta Machines
Are you referring to Meshmixer or 123d Design? I'm not familiar with the latter, but the former can sometimes take a while with large meshes.by n8bot - Reprappers
Personally I turn Solid Accuracy and Mesh density to the maximum, leave offset and min thickness alone, and see if the results are good. I use offset or min thickness to ensure the model is thick enough to print or to make it bigger and usually smoother. after you adjust the sliders, click "update" and wait a long while to see the results.by n8bot - Reprappers
click the edit button on the left toolbar, choose make solid. Increase the resolution sliders and adjust other properties to suit. Tada.by n8bot - Reprappers
Fusion 360 is not yet very well-suited for STL editing. netfabb basic has great ways to manually add triangles and seal up meshes. Also, Meshmixer has a function under "edit -> make solid" that will make it manifold, but it messes with the geometry and can increase the polygon count tremendously.by n8bot - Reprappers
My only guess as to the use-case for the different extruder schemes, it might be to manage a paste extruder or other finite-distance extruder and perhaps put a soft limit on the max value as to prevent damage to the paste extrusion system, or to allow more convenient refills. Having a dual-nozzle set-up, one PLA, one paste, is actually a goal of mine in the not-too-distant future.by n8bot - Reprappers
I agree that traxxas joints have given people a bad impression about spherical rod ends. The kind you showed look very interesting, indeed! I might need larger scale than the ones listed there, though, for my future prototypes. Have you run your machine with those specific rod ends? And it performed well?by n8bot - Delta Machines
G0 typically commands an uncoordinated move, which will make every carriage move immediately to the desired end position, causing the direct path you mention.by n8bot - Delta Machines
Quotedc42 Most people find the web interface reliable, only a few have problems with it. n8bot, if the server doesn't always resolve using its netbios name, try giving it a fixed IP address instead. Yes you can use the USB connection instead. These days I only use it for debugging firmware changes. The problems I'm having could definitely be related to my router, though it is a nice one.

If you need to make the nozzle higher above the bed around the extreme edges, raise the "delta radius" value (it may be called different things depending on your hardware). You may want to try raising it in 0.1 or 0.5 increments. If you need to lower the nozzle when it's at the extreme edge, simply lower that number.by n8bot - Delta Machines
dc42, I've found actually that even with an m906 I parameter of 1.0, after the 30 seconds, the motors lose some current and drop about 2 thousandths of an inch (I couldn't find a metric indicator, I don't know if they even make metric dial indicators.. and I'm in Canada!) is there any way to disable the motor current idle timeout at present? I'm using your 1.09kby n8bot - Controllers
One point about the web interface is that it is not as reliable as the panel due. The ajax connection can be lost, it doesn't always respond/refresh, and sometimes the server doesnt resolve at all. The paneldue ensures you always have control and readouts from the machine.by n8bot - Delta Machines
hercek, what type of ball joints are you using? I'm planning for a larger scale prototype and will not be using magnets in all likelihood. I'm not sure why the magnets would necessarily weigh more than a typical spherical rod end, though. There is the ball and the steel rod end. Are you comparing the weight to plastic rod ends like the Igus ones? Laurent, I always have heated up my bed and nozzlby n8bot - Delta Machines
I've tried 9000mm/s/s and the magnets did not pop off. I do not think any acceleration will make it pop off. I could likely turn off acceleration, command a 150mm/s move and either it would make the move very jerkily or the motors would stall. I've stalled the motors by hitting the endstops and no magnets popped off. The only time I had a magnet pop off was when I forgot to home the towers beforeby n8bot - Delta Machines
I think any magnetic joint system with sufficient magnetic strength is totally adequate for all delta setups. The limiting factor for acceleration seems to be the length of my arms, which are very long at 440mm. Also, the "maximum acceleration" is dependent on subjective qualities. Some people don't mind ringing artifacts and the like caused by high-acceleration and max-jerk settings. I prefer toby n8bot - Delta Machines
Not perfect, as nothing ever will be, but it's a great start: Printer frame is made from Misumi extrusion and linear rails, parts from Werner Berry (shopspt.com) and some custom pieces. I tried to keep the custom parts count to a minimum. Electronics are Duet 0.8.5 with dc42 fork of RRF (obviously). After I put this through the paces I'm going to refine the plans, make it as cheap as possible aby n8bot - Delta Machines
This is how the colours transfer over: you may need to reverse the direction, but that is the proper orientation when compared against the duet diagram.by n8bot - Delta Machines
