Seriously... some time I think I’ve got cotton wool instead of a brain.
Was trying to figure out why my perfectly prepared and painted stock was ruined when my CNC engraving design went off the top edge. Went back and checked my design... nope, looks fine... the stock was measured and cut exactly... so what was the problem.
Yup, I’d prepared the stock my cutting this one piece in two but not exactly. I needed my stock piece to be 325mm deep and the offcut was only 290mm... and I had picked up and prepared THE WRONG PIECE... so when I ran my job the v-cutting bit almost hit a screw when running out of stock. DOH!
So what’s your noob-stoopid mistake while using your CNC?

Not exactly a noob error and I've been at this a long time so the list is long but I'm Forever forgetting to Zero Z Dro after finding the material surface. What's worse is I've got touch plate or probe but can't be bothered to use them because I can usually set it quicker manually..

Actually think to today's while setting up a machine was a good one.??? . . . Couldn't for life of me understand why Mach3 wouldn't Reset.! . . E-stop was set and I'd pushed the momentary Reset switch for drives.???? . . . took me a good minute to realize I hadn't actually turned on the power to control box..

Most stupid mistake was to edit the .ini file in LinuxCNC v2.8 to set up auto-racking on my twin motor machine and then some weeks later run 'Stepperconfig' to change the acceleration. Took me all morning to realign the gantry.
An optimist says the glass is half full, a pessimist says the glass is half empty, an engineer says you're using the wrong sized glass.

Luckily I don’t make any mistakes. Anything you see in my videos are done on purpose to show you what not to do.
.. . think I got away with that one.
