Sam, I think you may be responding to my post in the Feature Request forum. At least it seems to answer my post there about a smart Canon EF lens mount.
For Pablo, make sure you have removed the black ring from the ASI1600 before attaching the EFW. Make sure there's no space between the red case of the ASI1600 and the EFW. They should be right against each other.
From this picture, you should only have parts #10 and #11 between the camera and lens, I have a feeling you're trying to use parts #7, #9, #10 then #11.
I can focus fine with my ASI1600, big EFW and Canon EF 50mm lens.
Unless you have the wrong Canon EF lens adapter. ZWO sells one adapter for use without the EFW: https://astronomy-imaging-camera.com/products/accessories/new-eos-t2-adapter/https://astronomy-imaging-camera.com/products/accessories/new-eos-t2-adapter/, and a short one for use with the EFW https://astronomy-imaging-camera.com/products/accessories/eos-lens-adapter-efw-asi1600/https://astronomy-imaging-camera.com/products/accessories/eos-lens-adapter-efw-asi1600/. If you have the first version, even at the shortest setting it will never be able to reach focus.
Thinking about the first version of Canon lens adapter, the connection diagram above is wrong. In the diagram the original Canon lens adapter is #2 (with an optional 2" filter #3), but requires #7 between the camera and lens adapter and it isn't shown that way.
