[[StopPosition]] [[CurrentPosition]]

Hello, I'm trying to use these two variables to make a formula, but I find that they always have the same value.

[[StopPosition]] 10

[[CurrentPosition]] 0.05

Can I be doing something wrong for this to happen?

I am using the NanoDLP1832 version

Thank you

You probably do not update position [[SetPosition]] as it required for RAMPS board.

Actually, I have done a quiz in which I put [[SetPosition]] to 20, and then I check it with [[CurrentPosition]], and it indicates that it is 0.05

Re: [[StopPosition]] [[CurrentPosition]]

Which positioning you are using Absolute or Relative?

There is a communication issue between pi and ramps, see if baudrate matches on both end and try change cable, you should not receive non english characters from RAMPS.
