If I'm using a 12 - 5V regulator for the servos, do I just connect the 12V input to one of the RAMPS D8-D10 and use the 5V output of the regulator with the signal wire pin on the RAMPS servos pins? You connect input to the same 12V power supply that powers RAMPS, and connect output to the "5V" pin (near Reset button), see raw.githubusercontent.com/maxosprojects/open-dobot/master/docs/images/ramps/ramps-v1.4.pngDon't confuse it with the "Vcc" pin, which is powered from Arduino's "5V". That is mainly the reason why you need a separate 5V - Arduino's 5V (Vcc on RAMPS) is low power and there is no integrated 5V regulator on RAMPS itself. Just in case, RAMPS schematics is here reprap.org/mediawiki/images/f/f6/RAMPS1.4schematic.png , where you can see what is what. |

No, but it's interesting. Are you going to try to implement dobot controller on it? |

Is there any improvement? My angle sensor didn't come yet so i couldn't try.
What we can do on open dobot with the current situation? Can we use g codes

I'm not following. What kind of improvements are you looking for, and what situation are you referring to?
On RAMPS only GY-521 accelerometers are supported, there is no other option as no one has volunteered to reverse engineer accelerometers that come with dobot 1.1. I only have dobot 1.0
There was never intention to support GCodes in open-dobot, though it is possible in principle to convert them to commands that SDK supports. G0 and G1 are straightforward, G2 and G3 involve some minimal math. There are many more of them, of course.
Using a preset pose you can use open-dobot without any sensors. Just set that pose in SDK.
