Dear friends,
I'm trying mach3 in my computer. Its fine. Today I changed my computer to compaq-hp nx 8220. installed fresh xpsp3. I installed mach3. I noticed that I cannot "ZERO" x,y,z axises. I cannot jog with keyboard and even with mouse (after I open jog panel with TAB key). keyboard works fine. Same problem happend if I use external keyboard. Funny thing is, If I use ZERO buttons with mouse BEFORE hitting arrow keys or TAB key (to open jog panel) I can zero x,y and z axises. No step motors nor drivers attced at this time. I compared all parameters, including hotkey setups with working computer. nothing is different. Also I noticed that in diagnostics screen, timer is not counting. on the working computer it continuiously counts some numbers. It appears that for some reason timer engine is not working. but there's no error messahes, warning messages on the screen. I tried different cpu speeds, but failed. this laptop have an ltp1 port to use with dock staton. I disabled it, changed lpt modes from bios (epp, ecp, birectional) but failed.
I installed different versions of mach 3 but owrking version on my orher computer is 3.42.20. I uninstalled driver and installed again, used driver.bat and special driver.bat files, reformatted computer, re-installed mach3 and even copied the mach3 folder from working machine to new one. still no results. I could understand if it could not run steppers and driver board but not able to jog with up/down keys and not-counting-timer in diagnostics screen is stange.
Also on drivertest.exe pulses for second textbox shows zero.
any suggestions ?
