CVI MachStdMill (MSM) / Probing

« on: December 04, 2010, 10:50:43 PM »

Dave.
    I have just started working with the probing routines with not much success.  The edge probes work with the exception of probe X+.    It moves to the edge and the probe light comes on and immediately I get "X+ face no found".  The vertical touch probe works.
   I tried to calibrate the probe using the cal routine.  Probe moves to X+,touches, probe light on, retracts to middle, moves to X-, touches, probe light comes on and immediately I get "1st circle measurement failed".  What does that mean?
 Next tried to find center of circle. Moves to X+, touches, probe light on, retracts to center, moves to X-, touches, probe light on, immediately "circle edge not in X/Y distance".  I have the X/Y dist set larger than the circle diameter.  Also, I am using the latest MSM and latest Mach.
  Any ideas??

Hi Dave..
     I suspect you have hit on it. I had not set any feed rate so don't know what it had defaulted to.
  One other question...
    I know what cont mode does.
    I know what step mode does.
    I know what mpg mode does..
  But what does S/V mode do??

Hi Dave
     I may have gotten alarmed over nothing.  I had the step increment set to one inch.
When I hit the key to start a step, I did not notice anything happening.  While working with it later on,
I did the same thing and noticed the gantry moving, veeery slow.  I had expected it to move at the normal
jog rate and did not notice that it was creeping along.  So it was, apparently, still moving when I would try to
go back to cont mode and nothing would happen in that mode.  Is this very slow movement the way
 it is supposed to work?

Dave..
  Yes to all questions, but nothing happens in step mode when I press an axis key.
Once I press a key in step mode, nothing will work in cont mode again until I reset Mach.

   How does one jog in the step mode?  I can jog fine in continuous mode.  If I
switch over to step mode, nothing happens except that it kills all jogging.
I have to reset before cont jogging will work again.  I am using the latest Mach and latest MSM.

CVI MachStdMill (MSM) / More Homing and Limit Switch Problems.

« on: August 06, 2010, 10:14:04 PM »

  I also have something strange going on with the limit switches.  I have a home switch at one end  and a limit at the other end of each axis.  Each switch is wired normally open and the two are in parallel.  X axis is connected to input 11, Y to 12, Z to 13, and A to 15.   The parallel port monitor page shows pin 11 to be low and the other 3 to be high as they should be.  In fact all are high and go low with switch activation  as is verified by looking at the LEDs on the breakout board.  Toggling the home or limit on the X axis makes the bit go high on the PP monitor screen.  Exactly backwards.  The other 3 display as they should.  All inputs are marked as neg active on the setup page and the homing/ref all works as it should.  
  So the question remains - why is input 11 shown backwards from the rest???

Hi all
    Does anyone know if the MP03 pendant from Peter Homann works under MSM??

General Mach Discussion / Re: ATC/ Rapid changer by Hightechsystems?????????????

« on: June 30, 2009, 07:20:15 PM »

Hi all..
   I have a set of the tool holders - the new style with the collet. Also made six more plain ones from 4130,  These are bored for 3/8 and 1/2 tools.  The colleted ones can take care of smaller items.  The 10k speed limit is real as I found out by absent mindedly cranking the router wide open. The spring unwinds and makes a terrible racket as it is flailing around.  I cured this problem by replacing the wire spring with a series of flat springs stacked together.  The ones I used are commonly used in electric motors to preload the back bearing.  I stacked these, interspaced with flat washers, to make the required height.  No more speed limitation.  I removed the armature from the router and then removed the original collet and replaced it with a blank.  After that, I put the armature in the lathe with a steady rest on the bearing and proceded to cut threads on the blank for a nice fit with the tool changer.  This gives me a nice short setup with no measurable runout.
