    Just realizing I didnt put the code on there to home. I have a case==2 statement that just has serial writes:

    G28.2 X0 Y0

    I’m actually using this to control a gantry, so I’m using a custom python script that writes to the serial port. Here is the code I’m using:

    ser.write(b’$XSN=3\n’)
    ser.write(b’$YSN=3\n’)
    ser.write(b’$XVM=1500\n’)
    ser.write(b’$YVM=1500\n’)
    ser.write(b’G20\n’)
    ser.write(b’$1tr=4.7\n’)
    ser.write(b’$2tr=.370\n’)
    ser.write(b’$XVM=1000\n’)
    ser.write(b’$1po=1\n’)
    ser.write(b’$3po=0\n’)
    #ser.write(b’$3pm=1\n’)

    ser.write(b’$XLB=10\n’)
    #ser.write(b’$XZB=700\n’)
    #ser.write(b’$YSV=700\n’)
    #ser.write(b’$YLV=1\n’)
    #ser.write(b’$YJH=1\n’)
    ser.write(b’$$\n’)

    case = 0
    speed = 10

    if(case == 1):
    # out = ‘G17 \nG02 I1 F100\n’
    # out = ‘G01 Y2 F10\n’
    out = ‘G00 X1.5\n’
    out += ‘G00 Y4\n’
    out += ‘G01 Y7 F50\n’
    out += ‘G01 Y4 F50\n’
    out += ‘G00 X20\n’
    out += ‘G01 Y9 F50\n’
    out += ‘G01 Y4 F50\n’
    out += ‘G00 X15\n’

    out += ‘G01 Z-.125, F3\n’
    out += ‘G00 X24\n’
    out += ‘G02 X22.5 Y5 I1.4\n’
    out += ‘G01 Z0.0, F3\n’

    out += ‘G00 Y0 \n’
    out += ‘G00 X0 \n’
    ser.write(out.encode())

    And here is the output that I get with $$
