Seig KX1 has a DC 500w Closed Loop Brushless DC Spindle Motor that drives the spindle with a belt.
Polarity just needs to be reversed either by physical wiring or some Mach3 settings need to be corrected.

Backup the current Mach3mill.xml (or other profile) and try to restore a past version of Mach3mill.xml.
If not please upload your current xml file to forum for others to analyze and help correct.

  Amazing what can be learned from someone who knows!! Is the spindle reversible, as in the gcode??
  Well according to this it only runs in the CW direction PDF manual >> http://images.harborfreight.com/manuals/66000-66999/66051.pdf

    Seems like the poster needs to find out more about his machine? If its not reversible its nothing in the setup file or gcode, so it must be the wiring.

I've just had a dig around on the  old support forum for the KX1/3 and in one of the threads there is mention of a direction pin for the spindle motor.  Unfortunately the FAQ section of the web site is not available and that did hold the actual pinout diagrams.  So if your KX1 uses the parallel port interface,  I would check your pin outputs to see if the the direction pin is working.  It could be oxidisation of the contact in the socket and it might be worth while putting some switch cleaner on the plug and socket contacts and doing a bit of vigorous plugging and unplugging to try clean them.   If I get a chance I'll see if I can put a port monitor on my KX1 and see which pin changes with spindle reversal.

Jim.

Direction pin for the Spindle of KX1 is PIN# 16 (see attached). Pin 14 pulse controls the spindle speed.
M3 and M4 should work.
Check whether pin 16 is working or not. Also check the physical relay.

about M03&M04 i know it. But the problems now is the spindle still rotate to CCW when i input M03. I think its not issue about wiring or motor problems.

Then why not try to tick (DIRlowactive) to pin 16  (output to spindle dir) and see what happens.

FYI
Forum Member kf2qd set his KX3 this way:

Spindle Axis - Enabled - Green Check, Step Pin# - 14, Dir Pin# -16, Dir LowActive - Red X, Step Low Active - Green Check, Step Port - 1, Dir Port - 1

Under the Spindle Setup tab -
Under Motor control there is a check in the Use Spindle Motor Output  and Step/Dir Motor, PWM Base Freq is 5 and minimum PWM is 0.
Under General Parameters all are 1.
