Does the latest release allow you to connect to a 3D printer board through USB or is that not yet implemented? I've been trying to connect an arduino nano which is running grbl but I've been having a lot of trouble.
Just moving the z-axis around, when I check the logs it says:

Level Layer Time Module Action Details

UNKNOWN /home/pi/go/src/github.com/julienschmidt/httprouter/router.go:273 (0x1fc3bc)

and when I hit calibrate zero position it spits out:
Info - 2015/12/09 02:11:58.324372 GPIO Moving to Top

which seems to indicate to me that it's using the GPIO rather than the USB/SERIAL connection.

This is the first time I've done anything on the raspi so it's probably some mistake on my part, but any help would be appreciated!

Hi Shahin,

I finally got around to installing nanoDLP build 947 and getting it hooked up with my printer, which is a Kudo3D Titan 1 printer that is a bottom-up Marlin based firmware with no shutter, tilt motor, or other moving parts besides a Z axis.

Projector control and display is working fine, no issues there.

However, I'm having some problems understanding how the Z-axis controls work.

When I connect to the printer and click on the 1mm down button, the system seems to send a G1 Z1, and if I click the 1mm up button, it also sends G1 Z1. This doesn't seem to match any behavior I would expect in either G90 (absolute) or G91 (relative) mode. If I'm in G90, a G1 Z1 will move the Z-axis to 1mm above zero, meaning the up and down buttons do the same thing and I can only bring my Z axis to exactly 0.1mm, 0.5mm, 1mm, 10mm, or 50mm above the build plate. If I'm in G91, since all the numbers are positive, the stage goes up whether I click on the up or down buttons and there is no way to lower the stage.

Additionally, the Platform Information numbers never change, and nothing happens when I click on either the Calibrate Zero Position or Measure Z-Axis Length buttons.

Is there something I'm misunderstanding about the way that these buttons are supposed to work, or something I'm missing in the 3D printer board setup?

Thanks!
