General Mach Discussion / Spindle problem

« on: July 22, 2006, 06:11:05 PM »

 I recently made a mini router .Everything works fine  except  spindle on-off  function. I set up  pin 17  as  output pin for the spindle.Sometimes I measure 2 volts  sometimes 4.45 volts on pin 17 . I don't know why it  is not stable . even sometimes  spindle runs during the jogging .I use  mach 3 running on my PIII 800 mhz laptop . I use solid state relay and opto isolated amplifier  pcb for the spindle. Sometimes  the signal is so weak that spindle  runs jerky( due to frequent on-off )  .Does anyone have a problem like this ?

General Mach Discussion / cardboard cutter

« on: July 21, 2006, 11:45:24 PM »

I would like to built a cardboard  cutter . It will work as vinyl cutter but I should add  a  fourth axis to turn the  blade  into the cutting direction. But I don't know how to arrange the A-axis to do turning job. Is there any cam program capable of doing  this  kind of job.
your help is needed.
