    Hi evryone,

    I m new and french.
    I hope I post in the correct topic.

    I just finish to assemble the eshapeoko an all its works correctly but i have an issue with my z axis.
    I explain :
    Spec: all nema 23 0.9deg,400 step
    TinyG 0.97

    I can move the z axis correctly with coolterm : homing cycle move the z axis up (g28.2 z0), if I send a g0 z50 it’s moving down, g0 z0 move the axis up, so its seems to be great.
    But when i use chilipeppr, if I click on the “+” for z axis its moving down and – it’s moving down, and its not the same on the screen (+ moving up at the screen) so when i try to make a part in Wood, the z axis go up for each pass and not down(from cambam), BUT the homing cycle is working fine.
    Do you have an idea?

    Thanks a lot for your help

    Best regards

    Julien

    You are in the right place.
    Very strange.

    Just curious, have you reviewed the wiki items on Homing and Limits?

    This behavior:

    But when i use chilipeppr, if I click on the “+” for z axis its moving down and – it’s moving down,

    Is hard to understand.

    When in Chilipeppr, When you click on the Jog Z+ and Jog Z- in the Axis widget, watch the Serial Port Console widget display (lower left of screen).
    You should see G0 Z__ commands heading out the Serial Port.
    What do you see?

    As a general statement, anything that works from CoolTerm should also work by typing the same commands into the Serial Port Console command interface.
    Is that true for you?

    What fw build are you running ion your tinyG? Most current is 440.14.
    FYI, firmware version (0.97) does not mean a whole lot, it is the FW build ($fb) that is more important.

    Hi i’ll go to Check.
    To precise in the serial port command ITs the same as cool term.
    Clicking on + move down and – move up.
    I send other informations just after testing 🙂
    Thanks

    Hmmm, I carefully reread your initial posting.

    I suggest you carefully read the Wiki item I mention above.

    By tinyG convention, the Zaxis home, if you have one, is at the top of travel, maximum + travel.
    Sending G28.2 Z0 or G28.2 z50 both initiate homeing cycle to find Zmax(home) switch. The value (0 or 50 in this case) does not matter but there needs to be something(“G28.2 Z” will fail)
    So, to be clear, G28.2 Z0 will move in a positive direction until the home switch is detected.The Z value at home will be a value, relative to where you set zero last, not necessarily Z=0 or Z=50.

    Chilipeppr Jogging: What OS are you running CP on, and what browser?
    Is your Keyboard set to lang=English or perhaps lang=French?
    Frequently, languages other than English do not get well tested.
    As an experiment, set your keyboard to English and see if that corrects the arrow key jogging issue.
