I don't know if it is a problem or  I do something wrong  when I increase the feed rate  Mach3  rounds the corners  of the cutting path .It is related with the accelaration   The more  acc  is  decreased  The more  the corners is cut round.  ???

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 ?

« 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. ???
