I am cranking out some more 3D models this morning. And pondering.
This mold failure is the motivation for me to transition to Linux CNC. The 2 arrows must line up for the plastic to flow through the runner. The runner on the left, pointed at by the right arrow, is about a quarter inch higher than it should be. This was the new Dodge interior with the pistol grip shifter. Ruined after about 9 hours or so.
This could be the result of a variety of reasons. The main culprit in the past has been failed or weakening CMOS battery or some Windows item in the background taking priority for a micro second. This is because apparently on Windows a virtual clock is set up within Mach 3 and it can be dropped in priority while Microsoft scrambles for some way to monetize everything. My CNC computers are not online but I think what happens is that many programs try to pop over and look for updates. My joystick to keystroke program asks me for a donation at least once a month. And there are many background things running in addition to the X mouse and joystick to key stroke programs.
Linux CNC wipes the entire PC and gives it a single purpose in life. Keep track of time down to the tiniest fraction of a second. No solitaire, email or anything else. No checking to updates or spamming me to buy some crap. It is like a Terminator except for looking for John Conner it simply watches the clock and makes sure steps run exactly as planned. At least that is what it claims to do. And it is free. There will be a learning curve for while.
