General Mach Discussion / pulse rating
« on: September 14, 2012, 07:59:38 PM »
Back to ground zero

My pc got a virus I ended up having to erase the hard drive an reload my backup disc.

my back up disc were made when i got pc but i hadnt backed up mach 3.

I had to down load microsoft  service pack  1, 2 and 3 .

I down loaded mach 3 lic but when I am trying to config I cannot get any motor movement.

I went to check driver test it show 0 pulse rating ?   Is this the reason i cannot get any motor movment.

                                                                          good day everyone
  my 6in round circles are not round
 there are 2 flat spots  one on each side of the circle  at 3,30 to 4 o clock  and 180 % out 930 to 10 o'clock.
both flat spot are about 1.5 long inches  the same .
 this where i guess.    I'm thinking it is backlash  and its OK if I'm thinking wrong 
 i am reading my manual as i am writing this.
   if this is a backlash adjustment  how do i know which axis to set or have a problem with.  I'm at 1511 units per inch
   is there troubleshooting manual or a book that i can get or  buy, download.
  it is hard to keep on asking questions I'm sure the answer is in my manual .
 p.s  i check on some schools here in town  to see if i could pick up a class on cad /cam . it is very sad  no classes, closest class is 165 miles  one way. 
  once again thank you for helping me
