    • In the following steps, we will go through the entire process of the calibration.

    • Plug the printer in, ensure the PSU switch is on and press the button on the front to turn the printer on.

    • Follow the instructions on the touchscreen and use this chapter to get extra information regarding each step.

    • DON'T POUR THE RESIN in the tank until you are asked to by the printer!

    • Never service the printer with the resin inside!

    • Spilling the resin inside the printer will most probably end up damaging the SL1. Be careful!

    • Never look inside the printer during the calibration of the screen or UV LED. There is a risk of PERMANENT DAMAGE to your eye(s).

  2. Please make sure you have removed the protective film. Confirm and then end this short unboxing Wizard by pressing "Continue" Confirm and then end this short unboxing Wizard by pressing "Continue"

  6. Don't open the lid under any circumstances, keep it closed! There is a UV light inside, which will cause damage to your eyes. Take look from above the printer. Your eye level needs to be above, not in front. Otherwise, you won't be able to judge the result correctly. Check the entire screen, you must be able to see our company logo in full. No parts (letters) should be missing.

Finished construction. 3 sessions of around 4 hours. Instructions wonderfully clear. It was a joyful experience to make comments as I went along and have them reflected in changes in the manual within a day or two. Did not use any spares.

Self check found two issues. It failed on the tilt motor test, most likely because I did not get the grub screw( that’s English for set screw) correct. The grub screw is inserted loosely, to allow adjustment, and I did not see any step finally tightening it. Is that Ok?. In the case of my problem, it was easy to reach in after removing the touch screen and set it right. The second issue was failure of the lid sensor switch. Probably also my fault. Just removed the back cover and resoldered a wire. If I had needed to cut some zip ties to reach, I would not have had enough spare. I think there should be a few in the spares .

Will be redoing my film on the resin container ( see the warning on the page about attaching the orange plastic lid). Now studying the printing manual.

You could add tthat people should check if the touchscreen cable is connected. My touchscreen didnt work until I plugged in that connector.
