Hi guys   at present  use  lock down version of  mach 3 on  my  cnc   but have  latest version with lazy cam  on  laptop  to  learn  to drive befor i upgrade   
I have been  trying to use lazy cam  to generate g code  to do photo engraving  i have generated g code  using the  V drill module
have set  to max depth  of  0.8 mm  with 60 deg  cutter

when i  generate  code  it gives  X  and  Y  locations  but  no  commands to  drive  the z axis   
any ideas  what i am doing wrong ?

thanks  Bill

ps  any one  know  if  in  latest  Mach 3  if  the spindle speed control  works  with the feedback  loop

What Rev of Lcam did you run?

Thanks
Brian

Hi Brian  2.66  it was with the download  of  mach 3  from  artsoft site

i have found that if in the options when you ask it to make gcode plunge clearance is  set  to  0  if  set it to  0.1 the it creates code with z at  0.1
if set 0 then it  gives no z at  all

it  may  be  that i am missing somthing vital  here  as i am  no  expert  and have only just started to try to de  engraving with my equipment

thanks  for  you  reply  bill

If you are at zero and you would like to move to zero there is no need to send out a move... Set the rapid height and you should be good
