I just watched this another forum and it seems fitting to post this for the Shapeoko community. While there are a lot of manual and NC operations this stresses the importance of workholding and sound CAM path controls:
I had to turn it off after about 30 seconds. As someone who has to keep a couple of big CNC machines running, that video is too painful to watch.
I too was wincing all throughout the videos…
I dread experiencing anything resembling what was shown.
The underlying message here is to exercise caution and don’t shortcut with solid workholding.
Very good advise,thanks for posting this as a reminder and freaking @robgrz out
I couldn’t imagine crashing one of those monsters!
Luckily most of mine can crash without that much damage
I did accidentally put my 1/2" left turning tool on when it was supposed to be a parting blade.
Parted right through 1-1/8" OD alluminum, with a 7/16 hole. before I got it stopped.
At 500 SFM, 1800 rpm, 3 IPM feed (CSS dont work right in Mach3).
It was scary and had to reset my tool offsets. It pushed the tool back in the holder about 3/16"
That was just a Chinese Shopmaster lathe, about 4 months ago.
