Looking for help understanding these hot points for CNC specific to how I use the X-Carve. I’ve done a lot of reading and experimenting and I’m still not getting it.
I cut mostly 13/16" hardwoods- Maple, Walnut and some softer hardwoods, cherry and poplar; and I usually cut either deep pockets or thru the material. Our main product that I use the X-Carve for are our nesting name puzzles. I will add some photos.
I also cut 1/4" maple MDF, pockets and thru.
I have never achieved a consistent small circle. I usually do get a good large circle. I can live with this, though it can be irritating at times.
My main issues are the inaccuracies and speed for the nesting puzzles. I use the Easel recommended feeds and speeds, because anything above that gives me inaccurate parts that require additional work to fit properly. I run the router between 1-2 and the my bits don’t overheat and the chips look good, I have run the router higher, between 2-3, but it has not seemed to make a difference. I mostly use these Amana bits.
My most recent experience is I was having bad cuts, I supposed the bit was dull. The parts weren’t fitting well and at the starting point for each object there was a bump were it seemed that deflection was making the cut off as it went around and then it realigned at the beginning and then was off again by the end. I wish I had a photo, but I don’t. The bump was perfectly consistent at every pass, so it wasn’t the motors stepping off, it always began the object at the right place, it just couldn’t make it back. So I changed the bit, did a few name plates, they looked perfect, and then the bump began to appear again. Surely the bit can’t dull that quickly.
I have not done the strengthening mods, I can, but at the speeds I’m moving surely that can’t be affecting my cuts. I had my G-Shield burn out on me recently and while speaking to customer service they suggested I tweak my potentiometers, as many of you do. I increased them precisely as much as he directed and my circles were terrible, so I moved them back down.
I have checked the square of my machine. I constantly adjust the v-wheels. I make sure that both arms of the gantry are at the same place before each cut. I always measure my bits.
So what are your thoughts. Wrong bit? Wrong speed? Wrong user?
@Earwigger @AllenMassey I’m calling you guys out 'cause you really seem to know a lot about this, but anyone else with experience with doing deep cuts in hardwoods, I love to know what your doing to make it work for you.
