edit

• Maintaining optimal tension is important for overall performance and frequency can effect speed and print quality. I know I'm being a little vague, but I'd like to hear what people have experienced with belt issues. Toothed belts have a fairly wide operating window. Some 3D printer brands come pre-packaged with the required hex wrench and tools to adjust both the X and Y axis belts. ) I thought that given my printer is a delta style printer there shouldn't be much variance between the axis. Mechanical and 3d printing issues can appear when belt tension is either too high, too low, or unbalanced. Others can go as high as 1500 mm/s 2 without any noticeable artifacts (I'm sure someone will chime in with their 50,000,000 mm/s 2 printer any second now). :) 1. Should be a sticker under the hood showing how the belt 3. While Delta printers move the print head by arms. I tried a few methods: moving the X gantry 150mm from the front, then I had problems with my first belts, because I overtightened them. By plotting the resonance data of the BELTS_SHAPER_CALIBRATION by Guilouz, I first got a similarly 1. My problem is I don't know how to scale the parts properly so I don't end up with a flimsy/under powered structure. Mooseheadm5. On a cube printer, it's a loose belt. If the printer is off you should not feel much resistance when turning the motor manual. I figured those were too loose. delta printers? 170_GT2_belt_drive. Tension is adjusted by loosening the screws, pulling the motor and its mount back, then tightening the screws. I decided to go through all the calibration processes for the k1 and for general CoreXY printers. I mounted the accelorometer turned by 90° degrees but got the same results. You can unplug the under bed cooling fan and print just the first 1/4 to 1/2 the cube to rule it out. You don't want to print other people's gcode anyway. Should be spring loaded, and use a ratchet in the square hole on the pulley to move it so you can get the belt slid on. You have to align the X and Y axis guide rails to be perpendicular if you want to print accurate square corners. The benefit of lead screws are rigidity - shear forces would not affect the delta end effector. The problem you will find with the dual motor setups on the ender 3 is both motors share the power from 1 driver, and that makes them useless. At some point I was able to print a full benchy (with visible issues on the side) but since then it’s been failure after failure. I bought some white belts with steel reinforcement and they stretched even faster, my running theory is that the steel has a great tensile strength under linear load, but this delta printer has a *tiny* radius on its idler wheel and the axis drive gears, so rounding that tight corner over and over broke the steel strands by On my cnc I use a fishing scale, I know that about one inch of pull on that should be four pounds. Here is a pic what I've found, which if it's not in the pic, it's located just below the knob that cuts the filament: The belt tension seems fine, the prints looking good, tryed a lot, back to factory setting, callibrating again and again. Now they're reading X 283 and Y 301. I've printed way faster. I found a helpful video for optimizing the belt tension on 3D printers by Prorifi3D there is some promotional content for their motors, but the majority of the video has useful information.

You really need a second driver if you want to really use that second stepper. The motor current is set to 900, and it doesn't seem to matter whether I print at 150 with 4000 for acceleration, or crank it right down to 20 and 1000 for acceleration. Is it the arduino board, the adapter board or what might be causing it? In the past I noticed that by putting a piece of paper below the arduino board (I'm guessing a short?) would have the printer working normally, but all of a sudden after a few prints its reverted back to the same problem. This happens as the belt wobbles too much when it rotates, creating mechanical vibration up the arm of the printer. It's getting pretty frustrating, because it seems to only happen with cylinders. I went the single motor + timing belt way. Try more cooling or lower temp and see if that The tension screw loosening isn't what causes your belt tension to loosen.
