The maximum light output of the Wintech projector used in the Ember printer varies from unit to unit. At the factory the projector in an Ember printer is adjusted so that all projectors have the same output (roughly 22.5 mW/cm2). This allows the same printer settings to be used across all Ember printers. As a consequence most printers can be "overclocked" by adjusting the projector settings to get more power out of the projector.

There are several advantages of doing this:

1) More power = faster printing

2) Control. A user can adjust the light intensity to compensate for changes in the optical system. These changes are primarily due to the PDMS, as the output of LED/DMD is very stable for months running continuously.

3) ??? The lightcrafter software allows access to the projector and some additional functionality. I am sure there is something here interesting. One could also access to HDMI feed to the projector as well.

Note, you may want to do the more torque modification while you have the printer open.


Tools needed:

Pliers

Sharp knife

Wire cutters

Drill (1/2" bit)

2 mm hex key

Mini-USB cable (included with Ember)

Lightcrafter software

4 mm hex key (optional)

Radiometer (optional)

Disk sander (optional)

Step 1: First we clean

There is always a bit of resin on the build head and in the nooks and crannies around the resin tray. Now is a good time to clean it up, so that resin is not transferred to your tools and computer.

<p>Is this equivalent to setting &quot;ProjectorLEDCurrent&quot; in Ember's settings to 255?</p>
Yes. There is no need to tear down the machine to control the LED current anymore.<br><br>Brian
