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 (Billy Jiang) 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?
