Build Your Own SLA/SLS

I am not sure what is going on? I am trying to print the calibration .stl. I hit show blank, It says everything is ready to go, I hit play.. the timer is going.. but only 1.44 % is done with 5 minutes into the supposed print. The Z arm is going no where the projector is not doing anything. What in the world am I doing wrong. I am connected with the icon where I can go back and forth showing Little RP are talking and I have done everything in the videos right on Vimeo with me checking 5 times over.

I put it on Com 5 instead of com 4 and now the projector is displaying the correct output and I am getting a completion update in creation workshop but the z-arm is not moving??? I do not have the same looking output in device manager as in the vimeo video like on the little rp site. Here is a picture of my device manager window. Can anyone help please??? Do I need a driver for the arduino??

Yeah, you'll need USB-serial drivers. Try downloading the Arduino IDE.

Which Arduino drivers do I use, I installed the IDE but that did nothing.

I needed to install the drivers from http://www.ftdichip.com/Drivers/VCP.htm .. as soon as I did that and plugged in the Little RP it was recognized on USB Serial Port (COM 6). The Z Arm is now moving and ready to print. Oh yea.. make sure you turn off UAC in windows 7 otherwise it won't let you install the drivers.

Glad you got it working- the manufacturer drivers were gonna be my next suggestion

Thanks for sending me in the right direction.

Just wanted to add that this fix worked for me as well last night.
