    Ok, thanks for pointing in the right direction. The $$ is NOT current working values. So, after I load my init settings, I do a m2 and all works as expected.

    Here is an example of the gdi issue:
    Even though the setting show $gdi=1, the gcode at the bottom shows the x axis moving in $gdi=0 mode.

    I use pyserial, monitoring for ‘tinyg ok’ before sending the next command. I also wait 1 second after sending the command before read, and one second before sending another command. I put the waits in just to see if I was overrunning buffers. The readout shows all successfully received.
    This problem is not just motor polarity. There are other random issues, such as homing in place, gdi=1 not working. A defa=1 and a soft reboot do not solve these problems. Normally I would attribute all this to serial port overrun.

    In minicom, I get a
    $gdi=0
    {“er”:{“fb”:440.20,”st”:9,”msg”:”File not open”}}
    [gdi] default gcode distance mode 0 [0=G90,1=G91]
    tinyg [mm] ok>`

    Although, I just tried a hard reboot (red button) and the gdi=1 started working. What is the difference between soft and hard reboot?

    or were you recommending to us ftdi with spi?

    you just described my dev/test environment with a 7 port usb expander and FTDI. Dev is Windows, test is Raspian. Wasn’t much on the web for the SPI. Thanks for the re-assurance. As close to plug and play and bullet proof as possible.

    This seems to work. My gearing is a worm on the stepper driving a 50 mm radius main gear, giving me 2 degrees of main gear turn to one turn of stepper.

    $1ma=0
    $2ma=1
    $3ma=2
    $4ma=3

    $1sa=1.8
    $2sa=1.8
    $3sa=1.8
    $4sa=1.8

    $1tr=2mm
    $2tr=2mm
    $3tr=2mm
    $4tr=2mm

    $ara=50mm

    g1 f400 x2 y2 z2 a2
    makes all steppers turn one revolution.
    The “a” stepper turns a little faster, but I can tweek that with $afr changes.

    Is there any way short of firmware changes that all four motors can be put into rotary mode? Or put motor 4 into linear mode?

    Thanks…this works.
    $aam=1
    $1ma=3
    $1sa=1.8
    $1tr=180mm
    G0 A90 moves stepper 1/2 turn and therefore the main gear 1/2 tooth = 1 degree.
    I appreciate your guidance.

    OK… using radius mode makes it much easier. Hopefully, I can set all four motors to this mode and run them independently. Thanks for pointing me in that direction. I’ll experiment.

    Yes, all gears in the gearbox have a 180:1 ratio for simplicity of design and coding. And, the Gcode will be hand-made as this is not a traditional use of this technology, but it seems simplistic at this point (I hear Murphy sneaking up behind me).

    Me… a developer? Flattering, but not true. Just proving technology before having the design engineers work on the physical aspects. Although, I will need an experienced developer soon for initialization, homing, faults, status checking, recovery, web interface, iOS interaction, etc. If you know anyone who is available: creeseratgmaildotcom.

    Added info. It is not a CNC. It is a multiple circular display with 22 steppers. So the CNC coordinate system may not be appropriate .
