autotoolzero

[pchfurniture]

I am still having a problem with my z axis. After initiating the auto zero tool in Mach3 the motor is retracting up to set height before it goes down to touch plate. My programs run fine but I have to use the paper under the bit method. I had changed out the drive. It worked fine before. I am totally frustrated...Please help Here is the VB script:

CurrentFeed = GetOemDRO(818) 'Get the current feedrate to return to later
CurrentAbsInc = GetOemLED(48) 'Get the current G90/G91 state
CurrentGmode = GetOemDRO(819) 'Get the current G0/G1 state

If GetOemLed (825)=0 Then 'Check to see if the probe is already grounded or faulty
DoOEMButton (1010) 'zero the Z axis so the probe move will start from here
Code "G4 P3" ' this delay gives me time to get from computer to hold probe in place
Code "G90 G31Z-4. F4" 'probing move, can set the feed rate here as well as how far to move
While IsMoving() 'wait while it happens
Wend
ZProbePos = GetVar(2002) 'get the exact point the probe was hit
Code "G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun
While IsMoving ()
Wend
Call SetDro (2, .250) ' change .060 to your plate thickness and then adjust for final accuracy
Sleep 200 'Pause for Dro to update.
Code "G1 Z1. F50" 'put the Z retract height you want here, must be greater than the touch plate thickness
While IsMoving ()
Wend
Code "(Z axis is now zeroed)" 'puts this message in the status bar
Code "F" &CurrentFeed 'Returns to prior feed rate
Else
Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if applicable
End If
If CurrentAbsInc = 0 Then 'if G91 was in effect before then return to it
Code "G91"
End If
If CurrentGMode = 0 Then 'if G0 was in effect before then return to it
Code "G0"
End If

Try jogging close to the plate, then zeroing the Z axis, then running the auto zero.

It's bad code, that could move up or down, depending on the Z axis coordinate.

Yes I have done that. I position about an inch above plate but still retracts. Could be wiring problem with probe and breakout board. I have the plate on the input 13 and the other from the clip to 5v or board. Not sure what to do.

Could be wiring problem with probe and breakout board.

If it were you'd get an error message.
