Anyone notice down cut bits causing their LR3 Core to lift rather than fully cut?
Single flute up cut (from V1E) was pulling up Polycarbonate panels, had to blue tape and glue down to prevent lift. Time consuming, so…
Tried new 1/8" down cut trochoidal 20mm/s when space permits. Works great without tape+glue, am just screwing ~2’x4’ panel around perimeter. However…
Noticed for small holes, using non trochoidal, that the holes are not fully drilled. Instead LR3 Core lifts up 0.5 - 1.0mm from the gantry, rather than fully cut down into the 1.5mm polycarb panel. Bearings rotate when Core is moved side to side, so I thought Core was snugged up ok, but seems there’s still enough of a gap somewhere that allows Core movement, slop?
Never notice this with up cut bits that pull into stock.
Like that down cut pins the stock down. Given LR3 Core isn’t fast to swap or print, am concerned about over tightening and cracking the core. Tempted to just create toolpaths that make 1mm extra deep cuts when non trochoidal. Can also slow feedrate to allow more time for sinking/plunge maybe?
