End-stop not hitting

Updated 4 months ago ​by Tomáš Chvalina

Your printer suspects that there is not everything in perfect order with your End-stops. 

Misplacement of your X/Y End-stops 

Most probably you have misplaced your X/Y End-stops during the assembly. The easiest way to check that is by doing the following:

Go to the LCD menu - Calibration - Show End stops. Once you are in this menu, manually click on the X/Y End-stops one by one. During this procedure, monitor if there is appropriate change on the LCD. 

That means: 
Once pressing X End-stop = X shall change from 0 -> 1
Once pressing Y End-stop = Y shall change from 0 -> 1

If that was not the case. Then you misplaced X/Y End-stop position on the miniRAMB board. So please double check the MK2/MK2S Electronics Wiring.

If the procedure above went alright. Then one of your End-stops just can not be hit. That means there is some assembly/ mechanical issue which prevents proper movement.

So please try to check following:

  1. You can easily manually hit the End-stops while moving with Extruder or Heated bed 
  2. Nothing is blocking the path around the Smooth rods and Heated bed cables
  3. With MK2S, it is wise to check that your Extruder cables are not hitting the miniRAMBO box. If they are, then re-adjust them.
