This is on a snapmaker. I’m new to this, and I keep running into problems figuring out this wood. I’m aiming on figuring out how to do grayscale in 1 pass. For this I had the power at 100%, 6 mm/min dwell time, and 1000 mm/min work speed.
Also, tips on how to do it in 1 run will help. The total time per run is 2 hours and 30 min.

Which method are you using to send the file to the Snapmaker?
I found that if you are connected via USB cable then you can get these dots. Caused by a busy PC interrupting USB communications if brief hits.
I now copy files to be lasered to a USB stick and run then directly from the Snapmaker…no more interruptions and black spot.
The other possibility is in your image. You will need to view your image and zoom in to see if there are marks on the image. Depending on your PC graphics you may not see the imperfections in normal view.

That is exactly what it was.
IMO what should happen is the entire gcode should load into the machine, and then you can use your computer as a way to remotely monitor and maybe change things mid way. Like I’ve been working on the laser side of things for the past while and I keep running into problems with settings. Plus it’s tells you on the bottom right how much time it thinks you have, where the SM1 doesn’t. It just gives you a % bar.
Oh well

Hey Folks, I know it’s been almost a year since this thread went quiet, but I’m curious to follow it up to see if anyone found a solution as I’m getting the same black spots and it’s not anything to do with computer connection issues via USB cable. My greyscale files are loaded directly to the Snapmaker 2.0 and it is running the file locally, but in watching the laser engrave the image, the laser just pauses now and then and the laser is still engaged and just burning spots when it shouldn’t be on. Any follow-up solutions?
