3018 z axis Inverted #1224

Closed dfkchase closed 11 months ago

dfkchase commented 11 months ago

So I installed some homing switched and when I did the set up for it I had to invert the Z axis so it would home up instead of down, but then even just jogging the machine around the z axis is inverted and cant seem to fixe it. I thought Having limit switches was going to make things better not worse. I'll leave my settings below. When z homes up as it should $3 = 2. It's currently crashing into the bed again with the below settings

Anyways, any help is appreciated.

$0 = 10 (Step pulse time, microseconds) $1 = 25 (Step idle delay, milliseconds) $3 = 4 (Step direction invert, mask) $2 = 0 (Step pulse invert, mask) $4 = 0 (Invert step enable pin, boolean) $5 = 0 (Invert limit pins, boolean) $10 = 1 (Status report options, mask) $11 = 0.010 (Junction deviation, millimeters) $6 = 0 (Invert probe pin, boolean) $12 = 0.002 (Arc tolerance, millimeters) $20 = 1 (Soft limits enable, boolean) $21 = 1 (Hard limits enable, boolean) $13 = 0 (Report in inches, boolean) $22 = 1 (Homing cycle enable, boolean) $23 = 5 (Homing direction invert, mask) $25 = 500.000 (Homing search seek rate, mm/min) $24 = 25.000 (Homing locate feed rate, mm/min) $26 = 250 (Homing switch debounce delay, milliseconds) $30 = 0 (Maximum spindle speed, RPM) $27 = 1.500 (Homing switch pull-off distance, millimeters) $31 = 0 (Minimum spindle speed, RPM) $100 = 800.000 (X-axis travel resolution, step/mm) $32 = 0 (Laser-mode enable, boolean) $101 = 800.000 (Y-axis travel resolution, step/mm) $102 = 800.000 (Z-axis travel resolution, step/mm) $110 = 1000.000 (X-axis maximum rate, mm/min) $111 = 1000.000 (Y-axis maximum rate, mm/min) $112 = 600.000 (Z-axis maximum rate, mm/min) $121 = 30.000 (Y-axis acceleration, mm/sec^2) $120 = 30.000 (X-axis acceleration, mm/sec^2) $122 = 30.000 (Z-axis acceleration, mm/sec^2) $130 = 290.000 (X-axis maximum travel, millimeters) $131 = 170.000 (Y-axis maximum travel, millimeters) $132 = 43.000 (Z-axis maximum travel, millimeters)

Changing $3 from 2 to 4 and back, changes both the Y & Z axis direction. Get your $3 correct for all axes to move in the correct direction when jogging. If the Z moves down during homing, adjust your $23 value to correct it. ($23=1)

Ah, thank you!!! I Had to change $3=6 before $23=1 would work, but its a successful homing and jogging scenario! Finally, all axis' work as expected. Muchly appreciated!
