    Hi guys.
    I recently received mu ox cnc that came with the CNC xpro Controller. I bought the OX from OOznest. Everything went well with the assembly but the electronics don't seem to work properly. Here is my issue. I have done everything by the book : Checked and rechecked the stepper wires on the board , checked the power supply voltage and it's bang on 24 V . I downloaded universal g code sender and the drivers for the board and i was able to connect to the board . I requested a $$ command and the board showed me its settings . I changed all the settings of the board as shown in apendix B in the Manual and every setting was saved properly . The first time i powered the board up ( this was before i did the changes in grbl ) the motors made a terrible whistle like sound , but , using the machine control panel , i was able to jog its axes. After i made the changes in grbl , as said in the Instruction Manual , the board stopped working . I have no motion what so ever. I tried adjusting the potentiometers on the board but nothing . The board connects to Universal Gcode and every single time it replies With oke when i star the connection . What is the ISSUE?
    these are the settings of the board.

    $0=10 (step pulse, usec)
    $1=255 (step idle delay, msec)
    $2=0 (step port invert mask:00000000)
    $3=6 (dir port invert mask:00000110)
    $4=0 (step enable invert, bool)
    $5=0 (limit pins invert, bool)
    $6=0 (probe pin invert, bool)
    $10=3 (status report mask:00000011)
    $11=0.020 (junction deviation, mm)
    $12=0.002 (arc tolerance, mm)
    $13=0 (report inches, bool)
    $20=0 (soft limits, bool)
    $21=0 (hard limits, bool)
    $22=0 (homing cycle, bool)
    $23=1 (homing dir invert mask:00000001)
    $24=25.000 (homing feed, mm/min)
    $25=500.000 (homing seek, mm/min)
    $26=250 (homing debounce, msec)
    $27=1.000 (homing pull-off, mm)
    $100=26.667 (x, step/mm)
    $101=26.667 (y, step/mm)
    $102=200.000 (z, step/mm)
    $110=2500.000 (x max rate, mm/min)
    $111=2500.000 (y max rate, mm/min)
    $112=2500.000 (z max rate, mm/min)
    $120=50.000 (x accel, mm/sec^2)
    $121=50.000 (y accel, mm/sec^2)
    $122=50.000 (z accel, mm/sec^2)
    $130=320.000 (x max travel, mm)
    $131=525.000 (y max travel, mm)
    $132=68.000 (z max travel, mm)

    IF i change $1=25 , the motors lock up and make that whistle sound , but when i try to move the cnc in jog mode , the whistle stops for a second and unlocks the motors , and then ,locks them back . What is wrong ?
    The power supply is the one provided by Ooznest with the kit 24 V , 14,6 A
    Motors nema 23 ( Motech Motor MT-2303HS280AW-c ) 175 oz , 2.8 A

    why do you want to change the $1? when you say "the whistle stops" is it turning at that point or no?
    Did you double check that you are connecting the motors correctly? make sure to have the two coil wire pairs together on A and B
    you can easily check which wires are pairs with ohm meter or by shorting two wires together at a time and see if the motor takes more resistance to turn..

    spoken to Ooznest and this was their reply :
    With the latest xPro boards $4 needs to be set 1. I believe this to be the cause of your issue.
    Problem solved .

    I am having this same problem. I have red and yellow lights by each of the drivers on the xpro. I changed $4 = 1 and I still have not gotten anything

    Here are my settings:



    $0=10
    $1=255
    $2=0
    $3=6
    $4=1
    $5=0
    $6=0
    $10=3
    $11=0.020
    $12=0.002
    $13=0
    $20=0
    $21=0
    $22=0
    $23=1
    $24=25.000
    $25=500.000
    $26=250
    $27=1.000
    $30=1000
    $31=0
    $32=0
    $100=0.000
    $101=26.667
    $102=200.000
    $110=2500.000
    $111=2500.000
    $112=2500.000
    $120=50.000
    $121=50.000
    $122=50.000
    $130=1320.000
    $131=1320.000
    $132=68.000

    It seems like when first booted up everything is fine, but when I go to jog on any axis, its like the xpro gets locked up. I cannot get settings or give any commands for that matter. All the lights are red on the back of the xpro besides the 2 y stepper lights. They are red and yellow.

    I think it could be because $100 = 0.00, it needs to equal 26.667
