Anyone here own a desktop laser engraver? I'm having this problem where my pieces aren't being cut completely. The material is being cut through and the laser moves the full path, but for whatever reason it looks like the laser doesn't fire at full power for the first few seconds of cutting a piece.



Laser: aufero laser 2

Drawing program: Autocad

Laser program: laserweb

All lines set to 100% power, all the same speed.



Anyone know whats going on? Any help appreciated.

Managed to record a pretty egregious case. Almost 8 seconds of no cutting despite the laser being on. You can see that when it starts the pieces the laser is shining brightly but when its cutting it dims down. The amount of time it doesn't cut seems to be random.

it's stupid, but can you take the shapes you've drawn and overlap the anchor points a cm or so? Doesn't answer why it's not cutting, but it might fully cut things out.

or post the first 40 lines of the gcode output

Here it is, I don't know much about gcode.

looks normal. Some shit is harder to cut through, especially white/reflective stuff because it'll bounce the laser off until the burning starts and it stops reflecting so much.

Could try scuffing up the surface, painting it, or using another material.

Otherwise g-code/laserweb-wise, there may be a dwell setting in your program which would park the head and power the laser for however long you set the dwell time.

I'm manually editing in the dwell commands in the gcode for now, but yeah I looked around and laserweb does have a function for dwell.
