Sometimes I'm really impressed

After about a 1.5 years of temporary locations for my S3XXL it’s finally found a home inside a dedicated digital manufacturing space.

To get it down here we had to carry it vertically down 3 flights of stairs and pretty much manhandle it… aluminium beds make it pretty unmanageable to carry down/up stairs even with 2 people.

Naturally, I expected things to be in need of a bit of calibration. But too my surprise on my frist DCS test…

Everything is within 2 Thousands of an Inch. Hats off to the Carbide Team on this one… I’m throughly impressed.

Is this PVC material?

Have you put your hand on the tool chest as the CNC is going all over the place? I just moved my Shapeoko off the floor onto a table, and I can feel the starts and stops on the table. I’m wondering if its worthwhile trying to weigh it down / stiffen it.

That sure is a beautiful space Mark…

Many of us have this material under our machines. Really helps with Tram marks and stiffens the spoil board. Doesn’t add any weight, stuff is extremely rigid.

Yes.

I do have some rubberized padding under my machine to help with sag. But yes if my hand is on the table I absolutely feel the motion of the machine. This is perfectly normal.

Okay, thanks for the pointers. For me, I’m on a Husky 6 ft x 2 ft table. I know the pads of the adjustable feet are pretty soft, maybe that’s what’s allowing the motion. X-axis motion is fine, but it is pretty bad when starting and stopping in the Y direction with my XL. To the point where my laptop screen wobbles. Surprising as the table and machine must be 200 pounds. When I put my full weight on the table, it doesn’t seem to help much. I thought I was moving up in the world, but I cannot avoid thinking the vibration is good for accuracy or surface finish.

you could tune down the acceleration in the grbl settings… cuts will take longer but less shaking

I think this has a lot to do with the construction of the husky workbenches.

I have 5/16” steel lashing it all together, but it’s just sheet metal for the rest of the construction and the energy from the steppers moving a heavy axis is going to travel trough regardless of how much weight you put on it.

Is the 8 wheel layout standard your own addition as well?

I ended up moving my unit back onto the floor for now. I had set the table up as 39" high for what I thought to be ergo reasons and to give me more storage space underneath, but having moving mass so high up and soft leveling feet at a 22" span aligned with the Shapeoko Y axis was probably a bad combination.

thats me, you can see that I use the factory threaded inserts to connect the 2qty 24x48" workbenches but then mount the additional two wheels offset equally from the “middle”. The backs of the two cabinets are also jointed together with the appropriate hardware.

Oh, I see. I didn’t realize it was two 24x48 tool chests back to back. That depth should give quite a bit more stability than just 1 chest.

Good evening Mark,

Seeing the eight wheels underneath your cabinets, I am curious if these cause the machine to move / roll around on it’s own at all as it is cutting a job?

I’m building a table for my machine tomorrow, and I have been considering putting wheels under it.

Thank you

Nathan

I typically have the wheels locked, but I have run jobs with them unlocked and no, no movement.

There’s probably some Principal of physics and/or the conservation of angular momentum that will explain why, but I’ll leave that to someone smarter than me.
