THIS IS A WORK IN PROGRESS
Xinkebot Orca2 Cygnus 3D Printer
If the previous person did not clean the bed when (s)he was done, you will have to use a single edge razor blade to scrape it off, and then clean thoroughly with Windex before proceeding.
First, view this video https://www.youtube.com/watch?v=fh5xY5OpKHQ up to the 3 minute mark.
The printer should already have been leveled and autoleveled before you are using it (directions below), but the z-endstop height can drift, so check it as it is done in the video.
1. Turn on the printer with the switch at the back left of the bottom frame.
2. Choose "Tool" on the screen.
3. Choose "Manual" on the screen. This is the manual movement control.
4. Check to make sure the nozzle does not touch the bed when moving the Z-axis all the way to zero. Do this slowly choosing the distance on the bottom of the screen. It's OK to use 10mm increments if the nozzle is far from the bed, but go down to 1mm or even 0.1mm as you get closer. If the nozzle is at the appropriate height, then you are ready to print. If not, you will need to adjust the Z-endstop, which is manually adjusted on the Xinkebot as shown in the video linked above.
5. I recommend turning the screw just a little further (maybe 1/8 turn) clockwise as viewed from below to make the nozzle just ever so slightly closer to the glass.
Prepare the bed:
For the size of your print, smear a thin coat of Magigoo in the center of the bed.
1. Choose "Print" on the home screen. If you are not on the home screen, you can click the "back" arrow in the lower part of the screen.
2. The bed will heat up automatically.
3. The nozzle will heat up automatically then the print will start.
4. Watch the entire first layer to make sure everything is going OK. If not, you need to start over. Click the pause button, then the cancel button.
