    The system seems to be MBOX. If it is intigrated with servo driver it is MDBOX, if it is seperate interface from drivers it is SC-MBOX V1-3. Doesnt help the manufacture name is also inconsistent.

    After some testing movement seems smoothed, like the interface using time to play even though we are feeding it 0 time. During initial testing with network interface plugin movement was very snappy. Testing with LFS this is most noticable going over curb rumble strips. Sending commands via network interface plugin rumble is very aggressive and quick. Using MBOX Plugin rumble stip is nearly completely smoothed out.

    MBOX plugin is sending
    55 aa 00 00 14 01 00 00 ff ff ff ff 00 00 00 01 00 00 00 00 00 02 46 85 00 02 46 85 00 02 46 85 00 00 00 00 00 00
    upload_2023-11-25_21-53-40.png
    Where Line value is "00 00 00 01" matching the Absoloute timing example value.

    When we where testing via network interface I was sending Line value of "00 00 00 9f" copied from relative timing example. I was also feading it a time value of "00 00 00 10".

    Can we try version of plugin sending static line of "00 00 00 9f"

    Line is just a line counter thou, I can't see it changing anything?
    But we can try for sure.
    May I have a pic of exactly what your using with the network plugin?

    @yobuddy If line doesnt change anything then maybe we need to provide a time value. Could be if no value is provided it is using a default value and that is smoothing output.

    I think we should implement the line output counter?
    But here is a test with the time set.

    @yobuddy

    Plugin with time vallue bringss back the snappyness.

    Couldn't test line vaule plugin as output is deformed. Looks like 00 inserted in every second space

    Yeah line seems to do nothing. But adding the time made a major difference.

    @yobuddy Just in case you missed it. The interface version with speed set and line static works great. If there is nothing else you need to do house keeping wise with it I would say it's a valid release candidate.

    Hi @Blastertoad,
    I'm just trying to figure out if the length is always suppose to be 100000 steps.
    Being that that axis are configure on the mbox, and doing this wrong would affect the total number of steps, I'm just trying to verify if we are always suppose to have 100000 steps for full range on an axes or not.

    Since this is a comercial integrated solution it can be paired with different motors and encoders. I think just leaving it as a variable it give the user either the option to program interface hardware to have it map movement in range, or set value in interface plugin like I have to get desired range for the specific motors.

    As far as I know, this is the only setting there is that could affect steps needed?
    Fn OC2=10 in mm, Lead Screw Calc (how much the rod advances for a full motor rotation)

    I'm not against it or anything, but I would hate to leave the door open to have people do things incorrectly, if there is a better way to do it. There may not be any 'same number used', but if they are not always the same number, I would think there would be a better way to find the number of steps needed is all?
