Coords shown on Display

in Questions & Answers

Hi,

as far as i know the coords shown on Display are the last ones from buffer, so i will never see the coordinates from actual move

until last command.

is there a possibility to Show actual move coordinates on Display ?

i know that will cost some speed , but for milling i don´t care about that as moves are slow anyway.

    That would be hard as the position is not really known. Under some circumstances we also have a realtime position counter. Used this once for delta to measure lost steps. But that woul be a motor position in steps and needs to be transformed back through steps and rotation and distortion and skew transformation to show real coordinates. That is the only way i see to get realtime position. A mid way would be to store start and end position for esch move you send in move buffer structure so yiu could interpolate.

    what about  adding  

    Printer::updateCurrentPosition(true);

    at end of G0/G1 (in commands.cpp)?

    shouldn´t that update display also?

    No, does not help. That is always working with last position in queue. It used to compute real positions in case yo9u moved stepwise.

    ok so simplest way for me and  realtime is counting pulses (with external Controller ), should be interesting to compare

    with some Motor-mounted high-res Encoders.

    might get nice playground for me ;-)

    You can simply count in step high function considering current direction as well.
