Setting the proper orientation for an object can be a little tricky - you’ll want to test different angles to get prints to stick to the build plate. Also keep in mind parts are printed upside down - because the build plate is oriented that way when printing.
You can optimize support structures to print with a tighter hold by upping the tip diameter. Under the support generator options you can update the defaults from .15mm to .5mm, this will increase the width so it holds objects more firmly - making print fails less likely. Can can also add your own custom supports to accommodate for any overhangs.
Next up we’ll need to slice the models for printing - this is done through the ember printer website. Here you can preview models to make sure everything fits correctly. To speed up prototyping we can print at a lower resolution of 50 microns and then adjust the model exposure time to 3.5 seconds.
The slice preview lets you visualize how the part will be printed and is actually just a stack of PNGs. You can also monitor your print job from any mobile device.
If your printer can't align the tray, then you may need to adjust the hall sensor. This is easily done by opening the front cover and adjusting the screw nut on the sensor so that it protrudes 2mm above the tray floor. Watch the video above for a walk through.
