DIY Makelangelo hanging after start.

[Anonymous]

Hey!

So I’ve been wanted to build a drawing robot for a while and finally got around to it this past month!
I’m running on and Arduino Mega with Ramps 1.4, and thought everything was going well until I tried to actually start a drawing. To be clear, the manual motor commands from the Makelangelo software work great, and everything seems to be ok until I click the start button for a drawing.

My output is below. Any help would be appreciated!

M226 is “wait for user input”. it’s waiting for you to click the button on the LCD panel. If you do not have an LCD panel you should rebuild the firmware with HAS_LCD undefined.

WOOHOO! Thanks! That fixed it!

Hi Dan! How can I undefine the LCD pannel? I just commented some lines where HAS_LCD appear in the lcd.h file but have no result. In the config.h I can´t find the LCD part, at least the “HAS_LCD” part.
I would appreciate your help!

Solved it!

In robot_polargraph.h I was able to change it.

Cheers!
