If I have a medium size cut, for example, a laptop engraving, how much data is transferred during that process? I know there is really no exact information that can be given, but I am curious. The engraving that I am thinking of is the one on the Macbook in the homepage video. I will be demoing th…

I would be careful about speculating. I think the size may vary widely depending upon the type of work you are doing. While even a complex vector cut pattern might be tiny, if you are doing a large raster engraving with grey scale levels (assuming that is possible) the size must be much closer to th…

Here is what @dan stated back in September: [image] Voltage and Data usage for the off grid user? We want to keep our bandwidth costs down to our servers, so it’s not too data-hungry - megabytes, not gigabytes, per print. We don’t have solid estimates yet though. This probably isn’t a big hel…

I guess what I am not sure of is what form is the data? I understand that it is not gcode so I guess it is lower level than that. If you think of it as a computer language would it be assembly language or perhaps machine code? Another metaphore might be what level on the OSI stack is it? Layer 3…

This doesnt really fall outside of the regular in the OSI model. Its gonna be layer 7. They probably have a proprietary format that is going to be similar to gcode in function. Its obviously going to be compressed, and as mentioned before (which I failed to take into account in my original post), ra…

Interesting, I was not considering an alternate to gcode, meaning the use of a home brewed higher language. Do you feel the data will be high enough to represent a vector as such and there will be a interpretor inside the GF? This high level would be created by firmware?

Even a lower level than that. [image] We’ll release a GPL-licensed firmware for Glowforge Bingo. We do both CAM and motion planning in the cloud. We just send the machine the actual waveforms to be fed to the motors (X, Y, each fan, focus, etc), laser, chiller, etc. There’s a bit of decompressi…

So from what @Dan said it is like layer 1 of the OSI model? Just groups of electrons coming down the wire…?

It would still be layer 7. They are sending a compressed package of information down over an internet connection, which is TCP/IP. Its basically a file transfer. OSI layer 1 is the physical hardware layer, like network cards, cables, etc. For anything to run on something like that, it would be very …

Correct, it’s basically compressed waveforms, so we can keep the local processing as simple, fast, and low-cost as possible.

How much data is transferred while lasercutting?
