Hi all,

Just curious what is the best working height for a CNC bench. I am going to build one for the CNC I have coming this week.

Thanks!
John

My Shapeoko 3XXL is close to 36" from the floor for the last 5 years or so. EasyPeasy to reach around on a 32" square working area.

The table is about 5ft. x 4ft. I built a torsion-box top. Its never drooped or sagged ( unlike me! :smiley: )

Thanks for the info!

My table including the spoil board is 39.75" but I think I would prefer it to be an inch or two shorter. I’m 6’ 1"

Mine is 40” and I’m 6’ tall. No real complaints.

Mine is 900mm, which is just about 36". Just thinking about it, a couple of inches taller wouldn’t be a bad option.

Benchtop height for CNCs is somewhat of a personal choice, just as it is for any woodworking bench. That having been stated, with the Sienci Labs CNC, which I believe are all open at the front and back, allow you to mill pieces longer than the spoilboard by sliding the workpiece forward or backwards. Having the height set to a standard one for all benches in ones shop allows you to use one of them as a work support for any of them. So to my way of thinking, decide first on the height of the bench you use the most, then use that as the standard for every working surface in your shop.

Thank you for that! I appreciate the insight and that makes the most sense!

Hey John,

When I was working electrical installations there was a running joke on how high outlets needed to be mounted. It was called the jewel rule.

Weirdly enough the joke stuck and became my to goto measurement for a lot of things, including my CNC workbench. I found it to be the best working height, being it not to heigh and not to low. And, bonus, if you need to reach and do something way back onto the bench, you don’t suddenly add an octave to your singing voice.

I sound bad enough as it is.

For my bench, I used the belly rule! :smiley:

The belly rule is a good one too. To be fair, I’ve cheated a bit by mounting spring loaded wheels that forces the setup to come down a few inches when a good amount of weight is put on top of the contraption. Unloaded it’s pretty much (younger me) belly height.

So yeah belly/jewelish height is best.
