Output of DAC question

I’ve compiled the branch with DAC support for the laser tool. It’s working as expected, except the output seems like it’s scaling for 3V instead of 3.3V. When set to S0.00 it starts at 350mV, then it’s linear all the way up to 3.3V. The tickle_power option is set to 0.0. Is this intended or am I doing something wrong?

I love Smoothie BTW!

Hey there.

Glad to learn the DAC works.

About the scaling thing, I’m not clear if it’s a problem with the code, a problem with the way the DAC works, or maybe a resistor on the board causing it …

Maybe somebody else will have an idea.
