Z axis cuts in the air - not plunging

Re this
HOME = 0
HOME_OFFSET = -64 I would set this as -1
HOME_SEARCH_VEL = 1.000000
HOME_LATCH_VEL = 0.050000
OME_FINAL_VEL = 2 This has a missing H
HOME_SEQUENCE = 0

SCALE = 2000.0 you might have to reverse the motor it can be done by putting a - before the 2000 ie. SCALE = -2000.0

Only 3 steppers for the axis - at the moment the spindle is a separate systemI will have a go at your suggestion and see what happens.
I have found that if I change something on one axis it can affect the other 2 axis - how can I stop that happening?

Are you editing the file manually or using stepconf . You should not be using stepconf as it will overwrite what you have changed

when you jog down with the page down key the it should go -ve

Sorry misunderstood there - you mean there is 4 wires for each motor - yes that's right. How do I know which 2 wires to swop?

Just change the SCALE to -ve

changing the scale to -ve makes the other axis reverse as well it seems
