LR4, Jackpot board, ESTLcam 13 (Running on Ubuntu/Wine)
I’ve done a few cuts now and things seem to be working pretty well overall.
I’ve squared the XY axes and levelled the Z axis as instructed.
A few things I’ve noticed:
Shapes seem to be slightly out of square, with a skew up and left. What’s the best way to correct this?
Looking at cuts along the Z axis, there also seems to be a slight taper, so edges aren’t perfectly perpendicular to faces. That makes me think the spindle/router might need tramming. How would you normally adjust this? I think the core has some adjustable screws along the top – would tightening/loosening those help?
Below are some pics of samples. I’ve tried to draw square lines on some pieces to highlight where the right angles should be.
The dogbone joint design here is by Aribabox. The joint fits well, but there are some optimizations to make still.
It’s specifically intended for 12mm ply. I’ve got a lot of 9mm stock on hand instead. What’s the usual approach for resizing dogbone joints when adapting designs for different material thicknesses?
Also, how do you get rid of the fluffy edges on plywood cuts? I’ve been sanding them, but this can take time. I’ve seen some people do a finishing pass or use a separate router afterwards. Or even on the CNC with a bit change. What would you recommend?
Anyway, if I can iron out these issues, I’m cooking with gas. Thanks in advance for any advice.
