The Ender 3 has a printable area of 220x220x250 mm according to the specifications. So, there is nothing wrong. Sometimes heated beds are slightly larger than the actual print area. E.g. 235x235 mm or 310x310 mm. For centering the nozzle to the build plate, you should look into "How to center my prints on the build platform? (Re-calibrate homing offset)&...

There are a lot of different print quality problems going on here, but the biggest I see is the bulging and sagging at the corners of each layer. This is a result of extrusion not being a zero-delay linear function of extruder motor motion, but subject to compression/pressure. This causes excess extrusion when printing slows down (approaching and rounding a ...

I see some possible issues at work here: Retraction issues on the arc. You might need to decrease your retraction length a little. Your bed might have a little play. tighten the eccentric nuts a tiny bit. As you are at it, check your X-belt, because accuracy on the Y move is affected by the accuracy of the X-head's position.

It is possible that the buildplate is too low, and cannot travel all way down the Y axis, but is hitting into the Y motor enclosure. If you have screwed the Z-stop to printer's vertical frame, shifting the endstop all the way down, there is even bigger chance for this. So one advice is to raise the Z-stop by about a width of wrench key included to the set. ...

octopus8 recommended doing a series of tests to determine the cause of the problem. I started with moving the bed by hand (remember to have machine off or choose "Disable steppers" from "Prepare" menu) and the movement was relatively smooth with some resistance, the same as when moving the X-axis. If you move very slowly you can feel ...

I ran into the same problem. After looking into the pin layout for the board I saw the following: #elif EXTRUDERS <= 2 // Hijack the last extruder so that we can get the PWM signal off the Y breakout // Move Y to the E2 plug. This makes dual Y steppers harder This prompted me to move the stepper driver and the motor cable to the E2 connector on the ...

There is a problem in the Megatronics default config file. I used an other default config file and it worked!
