Simulation time off since upgradinging to 1.4.05?

I run a Sculpfun S9 with Lightburn and I noted that the simulation timing are way off from reality (like 2 hrs estimated vs 3 hours running).
I am not sure, but in “Additional Settings” the speed is mm/sec, while on the screen it’s mm/min. Is this the cause? Or am I missing something else?

This should read from the controller on the laser and get it closer to accurate.

Interesting that Lightburn doesn’t automatically read this.

Hi Mike, Done that before making the screenprint. Didn’t change the numbers much…

The speed values are always shown in mm/sec, that’s no problem. It’s just a different notation for the same values (100 mm/s = 6000 mm/min).

The values shown in your screenshots look ok. If you still experience issues in laser time, it’s most likely because the laser cannot reach your desired speeds physically. Which speeds did you use?
