    Hello everyone I recently purchased a TinyG new and upon hooking it up I am not able to get one of the motors working. I have the stepper disconnected from the machine so I know it has nothing to do with the machine.

    When I move motor 4 the stepper makes noise but does not move, I noticed I can physically move the stepper with my fingers while its trying to move but then when the stepper is done moving it locks up for a couple seconds, Until it shuts off power to that motor per the setting.

    When I swap the stepper to another motor it works fine so im thinking it is the board or settings that are the issue. (Motors 1 thru 3 all work as they should) I have played with the current adjustment and have been careful to not overturn the pot.

    Full disclosure I may have have been a bit ham fisted while putting the TinyG in its case and knicked a trace with a tiny screwdriver but I just want to rule out anything else first before I go buy another one.

    Below is my $$ dump file along with the startup. I am using CNCjs if that matters.

    Greetings
    A couple comments on your $$dump
    1. Thanks, it usually speeds debug
    2. Give this wiki item a read. https://github.com/synthetos/TinyG/wiki/Power-Management $_pm=2 is usually the preferred choice, unless you have a specific reason to pick $_pm=3
    3. Are you sure that Motors 1 and 4 are 400deg/rev (0.9 Step angle)? That is how they are set up, it is just unusual to see.
    4. Did you choose $4mi=8 intentionally? $4mi= 4 or 2 is more typical, particularly for heavy Zaxis loads (heavy spindles) $mi=8 and $sa=0.9 makes for a very high precision Z axis, not typically required.

    All those settings are legit, just unusual

    tinyG boards are fairly tough, but trace damage is possible.
    Some folks have had issues with bad 4 pin connectors on the motor outputs.
    Pull your tinyG back out, use a Multimeter to check continuity of the motor 4 screw terminals and the solder blobs on the bottom. Also visually trace the paths back to the driver chip to see if they look to be compromised.

    FYI the tinyG V8 schematics are here for your reference https://github.com/synthetos/TinyG/tree/master/hardware/v8schematics

    I have the same problem. Did you ever get a resolution?

    @cheshirecnc
    The previous poster had several unusual parameters, it would be good for you to provide more specifics.
    What motor does not move? (m1-m4)
    Did you verify that stepper works on a different port?
    A $$ dump of your settings might help

    Update,

    Its been a whole pandemic but im back at this. I toned out J5 to its solder points on the back of the board and, following its schematic back to the resistor and the various points on motor 4 control chip. Everything seems fine there. Without a microscope everything seems fine visually. Next step I’ll take the board into a makerspace i go to and put it on a scope to compare the pwm waveform. Ill also re visit the config settings as well.

    With $mt=2, all motors will power down after 2 sec at end of cycle, that is consistent with your comments about manual lockup on startup

    If you are going to home the Z axis (you have a switch turned on)
    then $ztn=-75 and $ztm=0
    By convention, Z homes to the top of travel at position zero and movement is negative from there

    Doe anything change movement wide if you temporarily set
    $1ma=2
    and
    $4ma=0
    swapping the X and Z axes?

    Try setting all homing to 0 until the motors are moving
