I am a teacher in a high school with an Ulitmaker Original printer. We've had the printer for about a year and now there are issues. It's been used maybe 10 times.
It seems that the printer is "Lost" when it goes to start a print.
1) I recalibrated the print head by moving it to each axis and listening for the click.
2) I adjusted the bed height using the paper and nozzle trick.
3) When I try to print a file that I know works (from previous use) using the SD card, the printer head goes to the wrong spot and just moves in random lines.
Here's a link to the video...

any help would be much appreciated. I don't know much about all this but I would love to have my students do a design and build project soon!
