4DThinker True mate ,True. But they should not be so long that they project into the toolpath! made it hard to undo the collet. A good inch past the nut on the underside is too much even for the boot. and perhaps they might have been better poking up not down? would do the same job without interferi...

Rungemach I should probably be clearer on what I said before: My machine came semi pre-assembled. the gantry bolts taped to the side were too short- they did not even go all the way through.

For Ultrasign compsite board (Aluminium on HDPE), a 20 degree engraving bit (pyramid point) works very well up to 3mm deep. To use e...

Hi guys, just wondering if anyone else has issues with servos getting hot on long runs? My X axis servo gets insanely hot on long runs. have strapped on two computer CPU heatsinks which has solved the problem for now. Y axis gets hot too, but the X will actually burn you if you touch it! Adding the ...
