This error was changed in firmware version 1.5.0! This article only applies to SL1 printers with firmware older than 1.5.0.

During the Wizard, the SL1 will test the tilting-motion of the print display and resin vat (tank). In case the message "Please check if the tilting mechanism can move smoothly in its entire range" appears, the connecting rod cannot move as it should. This could be caused by something obstructing the movement of the tilt-platform or the mechanism not being installed correctly. Follow the steps below to troubleshoot the issue.

Before anything else, check that the tilt-platform does not have anything blocking its movements, like debris or forgotten tools, stuck between the sides of the screen and the tilt mechanism.

Disassembly and correction.

  1. Open the eight M3x5b screws securing the cover. Be careful to unplug the USB & Power-cable before removing the cover completely.




  1. Remove the M4x10 screw holding the right side of the touch screen. It is not necessary to remove the left screw. Just loosen it about a half-turn and you can slide the screen out, like a door. This will give you access to the motor and connecting rod.

Be very careful with the touch screen flat cable. It is fragile and can be easily damaged or cut.
  1. Remove the M3nN-nut from the screw that connects the tilt-mechanism and the connecting rod. You can do that by using a spanner or pliers to hold the nut and an Allen key to unscrew from the other side.

  1. Remove the two M4x8 screws securing the tilt-motor holder to the bottom plate.

  1. Remove the motor-holder and the connecting-rod from the tilt mechanism.
  2. Go to Step 18 of 2. Base & Tower of the assembly guide, and remake the connection of the connecting rod and the motor shaft.

Pay extra attention to this step, as not aligning the connecting rod with the protrusion on the holder as instructed will cause the issue again.
  1. Reassemble first the tilt to the connecting rod, make sure that after tightening the nut the two parts are in contact.

Do not over-tighten the nut!
  1. Connect the motor holder to the bottom plate using the M4x8 screws.


  1. Make sure that the optical sensor cable has its correct end connected to the sensor. The middle wire should be blue. In case the middle wire on the sensor connector is black, the connection will need to be swapped.
  2. Move the connecting-rod manually and see if it moves smoothly until the blade sensor-trigger is between the two sides of the sensor.
Make sure the sensor is secured!

  1. Slide the LCD back to its place, and tighten both M4x10 screws holding it.


  1. Connect the USB and Power cable and close the eight M3x5b screws that hold the cover. Tighten them in diagonally at first, and add all the screws before tightening them. Pay attention to the cables from the electronics so that they are not pinched.


  1. Run the wizard again.


After the wizard finishes, you are ready to calibrate the SL1.
