It is extremely critical. If they are not exact, the machine will suffer from mechanical effects. My first build had this problem and if you moved the effector/platform near the tower of the arms that were shorter, you would see the effector start to tilt up. If you moved it away, it would tilt downwards. So it effects how flat the printer will print and with changing angles like that, the printsby Wildcard - Delta Machines
It is just a layer fan for when you print pla. You don't need it, but many add it to reduce stringing and come out with a better part. I currently do not have a layer fan equipped on my rostock, and my prints have been good, but I am planning to print a layer fan shroud later today.by Wildcard - Delta Machines
My pleasure. Glad I could help. Go through the steps on Or You'll have to adjust the corridinates to your bedsize (if it is smaller), but once you have it printing flat you'll be off to the races. -Brettby Wildcard - Reprappers
Invert your endstops from their current setting (true/false). It also appears that the motors are moving in the wrong direction. Invert their direction. I'm more familiar with marlin firmware, but I will have a more thorough look at it later. But the problem seems similar to the one experienced in this vid: (Speed up to where he has the printer working). The problem was his endstops neby Wildcard - Reprappers
Upload your config. H so I and others can have a look. A vid could help also. If it makes a weird nose and shutters during the movement. Change the homing feedrate from 200 to 100.by Wildcard - Reprappers
When you run an M119. Manually trigger the endstops and see if they report triggered when you are holding it. And make sure that on the ramps, the endstops are in the correct location: the max enstops. From the left to the right, the endstops go x min, x max, y min, y max, z min, z max.by Wildcard - Reprappers
Glad you got it working.by Wildcard - Delta Machines
My first thought is to check your homing Feedrate. If it is 200 reduce it down to 100. That can account for the noise. Also check for binding. When powered off, if you place your hand under the effector, can you move the carriages up to the endstops with little effort? If it is hard , then there is mechanical binding in the system which could also cause noise. Also, post your configuration.h inby Wildcard - Reprappers

When loading firmware to use with repetier. Use the marlin.ino file instead of the marlin.pde.by Wildcard - Delta Machines
Printable radius only effects the area of the bed that the printer can effectively print in. The numbers that you stated above are incorrect because if you have a 170mm diameter bed, the your printable radius will be +/-85mm, not 70. If 70 is correct then change your delta diameter to 140mm. Getting rid of the concave or convex shape in the printer is done by either changing the "delta smooth rby Wildcard - Reprappers
Yes you can add a heated bed to allow you to print ABS plastic. ABS needs a heated surface to stop it from warping. 60 microns or .06mm sounds like a great resolution. Mind you, you won't be doing every part at that layer height or your prints will take a very long time to print. I have a delta robot 3d printer. I usually print at .3mm which is 7 steps above that setting. As for whether this machby Wildcard - General
What host are you using (pronterface, repetier, etc.)? When you calibrate are using the M666 code or are you making your changes in the firmware? If you are using the M666 code, are you saving your changes with the M500 code? Upon each start of the printer, run the M666L command to see the printers calibration specs. Write them down and make sure that you have your specs correct and as a baselineby Wildcard - Reprappers
The johann mini kossel version along with the other versions don't have servos and doing add too much weight. I originally wanted to use autocalibration because I felt that it would be a great way to get things calibrated for its first print, but the autocalibration is only effective if you have a good/nicely calibrated machine to begin with. Many have said that the autocalibration feature is notby Wildcard - Delta Machines
This would be under the proximity sensors, but the Hall-o effect sensor z-probe (others would be optical sensor z-probe) is one that I implemented on my printer when I first got it up and running. The downside is that it has to be manually deployed. I will say that I no longer use it because I prefer to manually calibrate, but I do recommend using this design because it is a good design and it waby Wildcard - Delta Machines
That's is a cool solution. The 3m Di-Noc vinyl wrap looks nice on the printer. Does it release good? My profession is composites—carbon fiber. I built a thick carbon bed for my printer.by Wildcard - Delta Machines
I've never tried the aluminum joints. I guess you would need to check their clearance and experiment. Btw what are dimensions of that machine- looks huge.by Wildcard - Delta Machines
Different strokes for different folks. Everything needs maintenance after awhile and even a magnetic setup can have slop, or may break down after awhile because you have metal on metal or plastic on metal which may wear down overtime.by Wildcard - Delta Machines
I use the traxxas. I bought them and used springs to take out the slop. I love the ball joints, I think they are the best in my opinion.by Wildcard - Delta Machines
octoprint is not just raspberrypi. There is a PC, Linux, and a Mac version as well.by Wildcard - Delta Machines
I recently just put springs on my traxxas arms to take the slop away. There is also a heating solution that was discussed on the google group on how to make he joints slop free without springs or bands. The steps were: Jun 14Doug LaRue since I've not seen it posted anywhere and had to figure this out here is how you assemble the traxxas joints( metal into plastic ).

I use repetier and love it. I had pronterface for a time, but it started messing up/not working on my mac. One that I would check out is Octoprint. I might use it if I go wireless.by Wildcard - Delta Machines
Yes a delta can be run by pronterface. I was running it on my mac until it stopped working--getting it to run on the latest Mac OS version can be tricky. But to your question , yes you can run printrun/pronterface with a delta.by Wildcard - Delta Machines
Okay. I was not suggesting that you mess with the steps just using it as a referenced point to find the feedrate. Which marlin fork are you using?by Wildcard - Delta Machines
Look inside your firmware configuration.h file. Go down to "default settings". You will then see #default_axis-steps_per_unit and below that #define default_max_feedrate. Change the feedrate and see if it changes the issue.by Wildcard - Delta Machines
Have you tried changing the federate in the firmware and seeing if that changes anything?by Wildcard - Delta Machines
What about slop? What if the problem that you are seeing is similar to the traxxas joints where the effector will still have small movement on the joints. Magnetic joints seem to suffer from the same occurrence. You may try adding springs to tie the arms together. Other people use rubber ands or print out connectors that clip onto the rods.by Wildcard - Delta Machines
