Just a guess but if the Z axis DRO has not been zeroed (suppose it reads 50.0000) then the Z axis will go down to get to 5.0000 (or whatever your touch off standard distance is) rather than up.
Unless your probing routine takes care of the G90 / G91 then yes it will make a difference.
As Hood suggested post your VB and check that you have everything set correctly in the screen set.

YES YOU CAN MAKE A UNIVERSAL MOUNT ON YOUR Z AND JUST MAKE INDIVIDUAL LASER MNT AND SPINDLE MNT. ( QUICK CHANGE )
 WE CAN BUILD ANYTHING HERE.  WE HAVE EVERY MACHINE IN HOUSE TO BUILD MOST ANYTHING.

A quick change laser head ??

I would really like to see a picture of a 450Watt laser fitted to the Z Axis of a machine.

Do you know the price of a 450 Watt laser ?

Rick,

I think all the software I use allows the 0,0 position to be set in the centre of the work as an alternative to the corners. On some jobs, such as your oval, it may be easier to mark the centre of the work and then set tool zero to this position.

The results are not really any better, OK the mis-allignment may be less but overall it is still a poor result.
IMO the reduction in the amount of error does tend to indicate that it is the belts/pulleys which are the main cause of the problem though.

Hi Jen,

My 2 cents.....

Routers for wood and plastic, Miling machine for metals (and some plastics).
Ballscrews are best and if the router has a table larger than about 600mm x 600mm then servos are best. Three phase high speed spindle with VFD is best and good dust / fume extraction is essential.
Exact model and where to buy - that's another story.

Sorry Guys, the confusion is all my fault.

You are both quite right, i don't have a use for Cut2D so I can delete this from my list.

It's more likely that the belts are innacurate. (almost the same pitch is different to exactly the same pitch)
