Atezr P20 Plus does everything fine EXCEPT photos

[lesclifton]

I have noticed that when doing photos on this machine the laser is very inconsistent, erratic, jumpy, and would operate at very erratic speeds on x-axis. The time estimate was not even close to the time it took as it took over 3 hrs to do a 56min job. The machine does everything else fine, shapes, graphics, lines and fills…it’s only photos. I have other machines and have never ran into this with just photos. It seems like possibly a setting but not sure where to look for photo specific settings.

I have checked all hardware items…belts, adj nuts, POM, etc. It is only photos so didn’t think it was a hardware issue. Any help or advice would be much appreciated.

Has anyone else had this issue with this machine? I searched and found another thread kind of related to this but had since been close with no disposition.

Thanks in advance!

i don’t use my grbl as much as I used to and I never used the Fast Whitespace Scan option, but it sounds like you have it enabled in the Machine settings. I thought it was limited to vector graphics… but…

Might want to check out this thread…

White space scan increasing adds more time?

Short answer: Increasing the whitespace speed pushes the engraver to spend more time accelerating and decelerating. It can also add time by ‘overscanning’ as it overshoots the edge of the image at speed to decelerate to zero. This increases the travel distance. Long Answer: Without getting into too much fun with the algebra maybe we can look at it like this. v0 = zero speed 0mm/min v1 = engraving laser speed say 1000mm/min v2= white space scan speed (laser off) say 5000mm/min n= number o…

Good luck

Images in general have much higher density data bandwidth requirements than other types of designs. Within images, grayscale will have higher data requirements than other modes.

It’s possible that the speed changes you’re seeing is due to the speed at which your machine is able to stream and process the image data.

You could try a few things:

1. reduce the DPI of the image so that less data is streamed
2. slow down in general. It’s possible that this could actually increase overall speed
3. I’m not certain of the exact controller in your laser but if it’s an 8-bit controller it could benefit from a faster controller
4. if your controller could be upgraded to one that allows g-code clustering this would like improve this.

Thanks for responses…Whitespace is disabled. I double-checked that to make sure. It is a new machine and I do not have this same issue with my Ortur LM3 with photos.

I will check controller, unsure…I just know this is the new 24W machine from Atezr and have only had it about 2 weeks now.

Thanks again for responses.

This is some strange marketing language about the Atezr P20 Plus on the Atezr site:

It’s not clear to me that Atezr has been around long enough to have 12 generations of motherboards but here we are. Their mention of 256-bit color is either misleading or incorrect. Not sure which. 256-bit color would be more than enough to assign a unique color to every atom on earth. It’s possible they mean 256 color levels which is really just 256 power levels which would be common for 8-bit controllers.
