Carve King Moves 2x what it should

[n8]

I ran into issues with my Carve King moving twice the distance it should in the z-axis.  I have replaced the Arduino, the CNC shield, all stepper motor drivers, flashed the Arduino, and verified all connections are correct.  Now all axes are moving twice what they should. All stepper motor drivers are set to .65 volts.  Does anyone have any idea/tips how to fix this???  Below are the $$ GRBL settings.

>>> $$

$0=10

$1=255

$2=0

$3=0

$4=0

$5=0

$6=0

$10=1

$11=0.010

$12=0.002

$32=0

$100=200.000

$101=200.000

$102=200.000

$110=3500.000

$111=4400.000

$130=432.000

$131=432.000

$132=95.000

ok

Check the jumpers on the CNC Shield. The step settings for the Z motor is probably set wrong.

What should they be set at? I have verified they are at .65V. The step settings for the Z-motor are at 200 step/mm. That's everything I can find on this blog to have the Carve King set to 200 step/mm. All 3 axes are moving incorrectly now.

I compared the  settings you posted on July 3rd with the Carve King settings shown on page 38 of the Carve King Assembly manual PDF from the MillRight Resource page.  Your settings differ significantly from those.  Here are the settings for the Carve King from the MillRight resource page:



$0 = 10 (Step pulse time, microseconds)

$1 = 255 (Step idle delay, milliseconds)

$2 = 0 (Step pulse invert, mask)

$3 = 0 (Step direction invert, mask)

$4 = 0 (Invert step enable pin, boolean)

$5 = 0 (Invert limit pins, boolean)

$6 = 0 (Invert probe pin, boolean)

$10 = 1 (Status report options, mask)

$11 = 0.010 (Junction deviation, millimeters)

$12 = 0.002 (Arc tolerance, millimeters)

$13 = 0 (Report in inches, boolean)

$20 = 0 (Soft limits enable, boolean)

$21 = 0 (Hard limits enable, boolean)

$22 = 1 (Homing cycle enable, boolean)

$23 = 0 (Homing direction invert, mask)

$24 = 35.000 (Homing locate feed rate, mm/min)

$25 = 1200.000 (Homing search seek rate, mm/min)

$26 = 94 (Homing switch debounce delay, milliseconds)

$27 = 4.000 (Homing switch pull-off distance, millimeters)

$30 = 12000 (Maximum spindle speed, RPM)

$31 = 5000 (Minimum spindle speed, RPM)

$32 = 0 (Laser-mode enable, boolean)

$100 = 200.000 (X-axis travel resolution, step/mm)

$101 = 200.000 (Y-axis travel resolution, step/mm)

$102 = 200.000 (Z-axis travel resolution, step/mm)

$110 = 3500.000 (X-axis maximum rate, mm/min)

$111 = 4400.000 (Y-axis maximum rate, mm/min)

$112 = 3000.000 (Z-axis maximum rate, mm/min)

$120 = 240.000 (X-axis acceleration, mm/sec^2)

$121 = 240.000 (Y-axis acceleration, mm/sec^2)

$122 = 240.000 (Z-axis acceleration, mm/sec^2)

$130 = 432.000 (X-axis maximum travel, millimeters)

$131 = 432.000 (Y-axis maximum travel, millimeters)

$132 = 95.000 (Z-axis maximum travel, millimeters)

Sorry I forget the new manual doesn't have this info in it.  Make sure these jumpers are set for each axis.  You will need to pull the stepper driver off to see the jumpers.

That did it! Running like a champ again!

Thank you!
