What Noob Stupid Mistakes Have You Made?

.. . think I got away with that one.

Obviously..

I did something similar. I couldn’t get the touch screen on my CNC monitor to wake up... then I realised I hadn’t booted the computer yet.

Sometimes it’s the little and simple things that cause the most problems.

Haven't seen the DAMHIKIJKOK abbreviation for a while now although it applies to quite a few of my posts. Most recent was carefully setting XY on my router to the corner of my last piece of good-quality ply and forgetting to hit the zero axis buttons on Mach3. Ended up with a very nicely cut gear wheel for the clock I was making with a neat half-inch slice missing off one side...

Oooooh, tell me more about your clocks and what software you use to design them? Wooden clocks was my main purpose in building a new CNC router, though I haven't made as much progress as I'd like.

Rather than clutter this thread with more random ratholes, here is a new thread where I can showcase the crap that comes out of my workshop. Waits for complaints about pushing useful stuff off the list - popcorn, anyone?

This thread as bloody Jinxed me.!. . Been at it again today. . . . Same machine this time while setting up tool changing wine Rack was manually jogging tools into holders to get X/Y coords for Macro then MDI to next location and repeat, note the coord's, switch into text editor alter macro and repeat everything went cushty..

. . . . Then for some unknown reason with tool still in the last holder, I go and enter into MDI G0 G53 X0 Y0 . . . Anyone Spot what's missing.?? . . . . Well when you do just imagine what a 125Kg gantry powered by by 2 x 12Nm motors taking off at 30Mtr/min would do to a wine rack .

I was on a roll last night...

I put a z-0 setter on my table so I can use the table as my Z zero. Ran it and it worked fine... the. Put a piece of ply stock on my table and I usually hit “Return to Zero” to check that everything is set... but now my Z zero is one the top of the table, not the top of the stock and... CRUUUUNCCH as my v-bit is rammed into the ply....

Luckily it hadn’t damaged the v-bit and the area where it went into the wood is 20mm away from where my part is cut... but I had to run homing and set up the coordinates again... all because I changed my Z zero location.

But then, I don’t know what I did, all my macros and keymaps and other setting for UGS just went POOF! I have no idea how I did it. Luckily I keep a backup of the settings but then found out that the macros have to be backed up separately... and I hadn’t done so.

So all my routines (including the go to Z zero one that got me into trouble earlier) will need to be manually put in.

Hopefully today will be better.

Forgetting that you set the cutting start depth at Z -10mm and watching the machine try to rapid plunge a 1mm bit through 6mm Alu plate.

Most of my 'mishaps' involve the milling machine. I spend 90% of my time in the workshop running my lathe, and the mill can go weeks without being switched on, so when it does, there is inevitably some re-learning required.

My most common mistake is still typing G0 G53 X0 Z0, then standing wondering why the Y axis hasn't gone to machine zero

Which is often followed by zeroing the wrong offset...

When our Maths teacher used to get caught out making a mistake on the blackboard, pupils would call him out on it, he would blush, turn around and grin and then say...

“Just testing!”.

It was like his catchphrase for when he screwed up... so much do that the whole class would join him saying, “just TESTING” along with him.

But of course he never got anything wrong. *wink*
