I just received an unsolicited Facebook message from a sales rep from Aotopto Technologies in China – he says:
I have a K40 on my desk.(Actually our company mainly do bigger ones.)
If you are interested just let me know.
For your questions, The machine MAY LOOK same , but the board may vary. But, about 80% the same.
And the box(main frame） maybe a little different ,like thicker iron box or thinner.
The pictures of the K40 on his facebook page (https://www.facebook.com/wuhanbilly) show some differences that are intriguing. Most notably, what seems to be a beefier gantry/rails system as well as mechanical limit switches. Not sure about any of the optics or electronics.
Has anyone heard of this company or had any dealings with them?
