I have some issues with the toolpath display.
Is it possible to clear the display manually or on cycle start - not regeneration?

My g-code for laser is of the form

G92X0Y0
cut profile
step to next start postion
G92X0Y0

this is done using subroutines.
When the g-code is loaded or regenerated it is displayed as expected. However, using cycle start the G92 seems to be ignored and the parts are drawn on top of each other. This makes observing a simulation almost impossible - not helped by the display not being cleared.

Also, G68 is sometmes being ignored. It works fine except it has no effect if a G2/G3 is preceded by a G91.

At the moment I am running Mach3 offline prior to upgrading our machines, so I don't know if there are actual errors with the g-code or faults with the display.

Finally, is there a way to speed up the simulation?

It is a display thing I think.

Thanks for the second opinion. I can now ignore the display and get on with writing a new post & a converter program.

Does anyone know a fix for a simulation that doesn't simulate?
