Might want to read this if you haven’t found it in your search of the site.
Although a dsp controller is generally more expensive, they are much better for laser control.
If you limit it to desktops, what’s available is pretty limited.
You need a liquid coolant with dc excited tubes, you have to have plumbing and the cooling equipment. This puts practical limits on the size a desktop can be.
A common item is the power output. The power output of a co2 system is dependent on it’s length.
A 50W tube needs to be a meter long, 55W even longer. Since all of these cases are not more than a meter in width. I doubt the output values they claim.
My OMTech China Blue 50W was a bit over 40W when measured and only 880mm in length. OMTech isn’t stupid, they knew this when they built it or had it built also when they wrote the advertisement…
40W doesn’t sound as good as 50W… I guess…
Unless you cough up about 10 times the money, it will be a Chinese machine. Most technical service requires a 24 hour turnaround time. It’s the middle of the night over there for most of us.
I haven’t seen a thunder laser desktop… but you always have to add the chiller to it’s foot print unless it’s a desktop.
With a desktop, the parts are not standard, much worse than the rest of them… the optics and coolant systems seem to be rater custom.
How easy a clean/alignment is done on a desktop by the user, I have no idea. I’m sure someone can advise us.
The OMTech Polar can be diy fitted with a console, which I couldn’t live without. Also allows the use of user origin and change it’s ip.
If you watch a few of these videos, you can get a better idea of what may become an issue for you.
The P2, Onyx, Gweike Cloud, Polar and Glowforge are desktops that are relatively close…
I put in Glowforge, but it’s not really a consideration to me. Expensive, requires an internet connection and it totally proprietary, both hard/software wise.
This video compares Polar to Gweike…
These point out annoyances about the product… sometimes a good to know. There were some odd things that surprised me.
@bionicback321 link is to an Ebay OMTech… I’ve seen lots of griping about this type of purchase… They try to go back to OMTech for warranty and/or service where they are directed back to the original ebay site. You can get good deals, but you may not be getting what you think for warranty and/or service.
