Hey Tom,
there is a systematic error in your test. After you have assembled the QCW frame, equipped it with wasteboard and mounted the Onefinity CNC on it, you go straight to flattening the wasteboard. That does not seem logical to me.
You yourself report that the wasteboard is milled unevenly, even only partially, and that the work surface slopes down from left to right.
Your report lacks a proper diagnosis, at least at this point. You just make a few assumptions on why it could be twisted or sloped, but then you wipe everything away and conclude with the statement:
“But that’s okay, that’s why we flatten the wasteboard”.
This is a wrong assumption. As long as it is possible that
- one machine foot is higher than the other (frame twisted)
or as long as
- the frame is not really square,
you can flatten your wasteboard for as long as you want, you will never get accurate results.
After finishing assembly, you obviously didn’t check either of them.
But that is what we ask, we all the customers who ordered this QCW Frame, what we want to know:
- Is it plan (not twisted)?
- Is it right-angled (Is it not a parallelogram)?
As surely many do, me too appreciate your efforts in bringing information to the community, thank you very much for this.
But I would be careful with offering such a test in a video without proper checking and reporting these two points.
I am sure it will be much appreciated.
Do you think you can check especially the twisting. Is the QCW Frame able to ensure planeness?
