Hey Robert,

@RJK75

A additional clarification if your using the qcw is anything actually bolted down to a table or is it free floating on the four leveling feet. I ask because I know carbide 3d is totally against attaching to a table for risk of damage to the machine if it’s not perfectly level twisting the structure.

The adjustable feet, called “Any Surface Leveling System” and that are now included in a QCW frame, are what makes it possible to adjust coplanarity (=“twisting”) on the fly. The question is if it’s reasonable to buy the rather expensive QCW frame just for this feature. Most people here build an anti-torsion box of plywood (which can be much stiffier than the QCW frame) and put it on a table that has leveling casters which allow to adjust coplanarity too (if you are willing to bend downwards to adjust them each time after having moved the table :))

@Aiph5u

the QCW Frame, when it came out, provided what the Onefinity machine was lacking to be a complete machine: A machine base. But

• it is rather expensive
• It is by far not as stiff as a welded steel base (okay, no one would expect that). It was even reported that it bent when drilling/sinking on a workpiece
• There is a rather large wasteboard area that you can’t use at the rear (you could even leave that area out when putting MDF slats on it), and a wasteboard room at the front that is clearly missing, as the milling motor is not located over the area with the T-tracks.

The advantage is that the Any Surface Leveling Feet are now included (before, you had to order them separately here) so you can put the machine somewhere and make it coplanar immediately (use fishing line method) and start to mill something.

Step 3: install the connector for the levelling foot inside the rail opening

As for rectangularity (“squareness”) of QCW Frame, I haven’t checked yet. Will report as soon as possible.

On the other hand, I think if you make a 2-3" thick (anti-)torsion box out of 12 mm birch plywood, as many did here, as a machine base / table top, it would not make much sense to use the QCW frame, and such an (anti-)torsion box can be very, very stiff. However adjusting coplanarity would have to be done with shims under the feet then.

@Aiph5u

By the way, when mounting the Onefinity CNC to a table top, I always suggest not to use the wood screws that come with it, but bolts instead, or better bolts in sleeves (e.g. brass) with bolts in it. Their diameter would need to be exactly 8 mm:

I bought a QCW frame to analyze it (ouch to my wallet), and will use it for testing purposes and will report then. But I will not use QCW frame in my final assembly. However many people are very satisfied with it.
