Hi
I've got a basic 540 cnc router.
When manually jogging the machine, it would jam at some places but not always at the same place every time. As a result my cuts are not perfect for example a square will cut first ok on first depth pass but on second on it stops in y axis whilst mach3 is running but then works ok a x axis which as a result forms a rectangular shape. Any ideas on how I can stop this. Should I use spirit level, loosen bolts, lubricate?
