I have an Ortur LM3 I am learning to use, I have a project designed and started engraving the total time is said tobe 3:38 do you feel that is longer then it should be for a 12in x 12in snip below?
I have it set at 80% and 2500 speed.
Forgot to say this is a Fill project.
Can you go and click on the preview window
it will show all the engraving paths
seems a bit long time but 12x12 should take a while
Maybe you can optimize the white space movements
the previwe will show what can be done
Well, we can’t see your line interval, but your speed also seems very slow to me. With a line interval of 0.1 and the same speed, my machine also uses 3.13 hours. With 400 mm/s it still takes 51 minutes, but it is a reduction of 2 thirds. Is there a specific reason why you drive so slowly? I think your machine is rated for 20000mm/min, so the time should come down to about an hour…
That would be 3 min. 38 seconds so no. Sorry didn’t see window to the right.
Offset fill would greatly reduce things.
3:15:27 
time waits for no one…
I was thinking 3:38 in preview window
Like I said it would greatly reduce time. 
If I go any faster it do not show any thing even i that speed I am going to have to run it again. Not sure if my setting are off.
Im happy to try it. until I previewed it I didn’t know what it did,
If we’re talking about mm/min, your 2500 corresponds to 41.67mm/s, that’s a speed others cut different materials with.
It is a pity that others with the Orthur lm3 do not jump in with their experience of a reasonable setting and speed of their machines.
I would recommend doing a material test, use the one from LightBurn or make your own.
Another possibility is that your focus is very off or your diode is not working properly.
