Hi Sam,
This is the code I am using without any issues. It is very similar but with slight differences.

CurrentAbsInc = GetOemLED(48) 'Get the current G90/G91 state
CurrentGmode = GetOemDRO(819) 'Get the current G0/G1 state
CurrentFeed = GetOemDRO(818) 'Get the current feedrate
DoOEMButton (1010) 'zero Z DRO
PlateThickness = 2.8 'Touch plate thickness is set here
ProbeFeed = 10 'Z axis feedrate is set here
If GetOemLed (825)=0 Then 'Check to see if plate is already grounded
Code "G31Z -15 F" &ProbeFeed 'Probing move at ProbeFeed rate
While IsMoving() 'Wait for Z move
Wend
Code "G4 P0 .25" 'Pause for DRO to update
ZProbePos = GetVar(2002) 'Exact point probe touches
Code "G0 Z" &ZProbePos 'Go back to exact point of touch if there was any overrun
While IsMoving () 'Wait for Z move
Wend
Call SetDro (2, PlateThickness) 'Set DRO to plate thickness
Code "G4 P0 .25" 'Pause for DRO to update.
Code "G0 Z5" 'Z retract height is set here
Code "(Z axis is now zeroed)" 'Message for status bar
Code "F" &CurrentFeed 'Reset original feedrate
Else
Code "(Z-Plate is grounded, check connection and try again)" 'Message for status bar
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

Thanks for the reminder Dave.
I, for one, sometimes exist in my own little world and are not always mindful of others.

Sam, could you post your macro code.

A bit more progress on establishing the beam path. It has to get from the laser tube to be running parallel and plane with the X axis where it is again deflected (by a mirror on the X axis) to be parallel and plane with the Z axis. The focus lens will be mounted directly on the Z axis whereby the focal point can be adjusted for different thicknesses of work.
This is the wooden mock-up including adjustable mirror mounts made from MDF (yuk !). The little HeNe beam is quite square to the table in both planes which I think has resulted from a lot of luck.

Oh dear Chris, now you have gone and mentioned Twinkies.
It took me ages to find out what Tootsie Pops were.

Hi Bob,
Don't know if this is any help but I recently had a PC failure and had to use another PC which had Win XP SP2 installed and I experienced exactly the same problem as you have described. After much time wasted trying to resolve the problem I installed Win XP SP1 over the top of the existing installation and thereafter no problems at all.
It has to be something to do with the way the PC handles its polling routines and the way this is interpreted by XP SP2.

The High Voltage PSU is now complete and it's time to start working out the best beam path from the tube to the Z axis.
I have made a frame of the same OD as the CO2 tube to hold a little HeNe which sits in the CO2 tube mounts and is ideal for this job. The mirrors I am using are OK for the 633nm and getting the beam path sorted but will need to be replaced with a type that works at 10600nm.

I have no problems at all with Firefox. You could try uninstalling it, cleaning the registry and installing the latest Firefox version.
