Mach3 and G-Rex / ruining my new cnc from the beginning.
« on: February 16, 2015, 01:50:01 PM »
hi!
i finally turned on my cnc after 9 months of building it and ran in to problems within seconds of starting mach 3, im hoping someone might be able to point me in the right direction
i have no experience with mach 3 so im sorry if i offend any one with my ignorance.
im using a cncrouter parts machine with their XML set up files.
when testing my 3 axis cnc the first thing i did was jog the motors to make sure they worked in all directions. they did. second i hit the home button to see where it would home on the y axis, it went in the opposite direction i wanted (+), but hit the limit switch and stopped. no problem. then i did the same with the x axis. it did the same (moved in the + direction) except when it hit the limit switch i think one motor want to keep running because it started jumping off the rail but it wasnt hitting the limit switch. so i hit the emergency stop button.
i looked up how to reset the location of home and changed the settings in mach 3. but when i returned and tried to test it it wouldnt home and it wouldnt travel in the positive x axis at all.
so im stuck now. im not sure how to diagnosis the problem. there are no warning lights on the diagnosis page on mach 3.
any help would be much appreciated.
