new protocol? Neje DK-8-KZ

[firstel]

I just got the engraver a month or so ago. I can connect to it, but only the up/down/left/right buttons work. None of the other bottoms work, and I can not do any engraving..

The Windows app from the manufacturer says "Software Version 4.0" in the bottom left of there desktop app.

I have the new version of this machine as well. The Neje software takes forever to launch and doesn't work properly and i can't find support for it anywhere.

EZGraver seems great, but v3 is the only protocol that gets any reaction from my machine at all. The direction buttons work, and upload works. when i click draw preview, it draws the outline box until i click the center button. But when i click start burn, it does nothing. Please help. What indformation can i provide to get this updated?

I am having a similar problem to EllyS215. Would be happy to help provide any information needed to update this so that it works with the latest releases of this unit

I've got sources from factory v4 tool, and i will work on v4 protocol implementaion

This is great! So this will be a mac version? I'm so excited!

I agree, this is great! I hope that the new version will be released soon. Because I just bought NEJE DK-8-KZ engraver recently and I can't use it. The official application is randomly cropping every picture I try to print (which makes it unusable) and EzGraver isn't working since the protocol changed (when I click Start the engraver won't do anything, but the moving and preview functions work).

[anabolyc]

I've checked in develop branch to windows version. There i fixed crop bug, also removed call that uploads every image you carve to chinese servers (yep!), alro removed call that downloads full library from chinese servers before start, so it starts quick now. I'm still planning to implement this in EzGraver but i might take some time

[janoi152]

Wow, thank you! That sounds really great and I would like to try it right now but I don't know where are the binaries (executables). I checked your develop branch but there aren't any releases and I can't find any executables. To be honest I was always confused by GitHub (especially when trying to find compiled binaries) and I don't know how to compile that code. What should I do, please? Thank you.

[janoi152]

So I've tried to compile (build) the code in Visual Studio but I'm getting 1 error and 5 warnings. The error is "'Form_main' does not contain a definition for 'pictureBox1_Click' and no extension method 'pictureBox1_Click' accepting a first argument of type 'Form_Main' could be found (are you missing a using directive or an assembly reference?)". So I don't know what next. But a compiled version would be really appreciated.

[anabolyc]

Sorry, my bad, just sync latest, it is fixed now. And thumbs up for challanging build yourself:)

[janoi152]

It works! Thank you very much!

[firstel]

Wow! Where can I download the updated mac app?

[tseho]

hey @anabolyc, do you need help for porting the v4 (and v4.2 ?) protocol to EzGraver ?

[anabolyc]

Hi @tseho, unfortunately i'm currently quite busy with other project. I checked in WIP state to my fork. Engraving part is still not working correctly unfortunately, i have windows version working in parallel and seems that data exchange model changed since v3. You may have a look If you have possibility to run windows version as well.

[tseho]

@anabolyc thank you for the work in your fork, I will see if I can make it work.
I will post here if there is any progress.

[tseho]

Hello all, after trying to work on @anabolyc code, I gave up after failing to understand where the issue was.
Anyway, I started from scratch and it took me a while but here it is, the "HowTo" send an image to the graver.
https://github.com/tseho/gozgraver/blob/863c0d2feadcd7ff4fc27be0fbcab0cab3dbd32e/core/protocolv4.go#L40
So, if anybody want to reproduce the protocol v4 in EzGraver, I commented as much as possible to explain what's expected.

Currently, tseho/gozgraver is an undocumented command line utility, only tested on linux.
