Dear friends, I have an old XCARVE 2016 with a 1000 mm rail size. When I cut hard materials, XCARVES go off the path. When I return to soft materials, everything goes well. I have checked the wires already. Should I have to check the power supply, too, or decrease the feed and plunge rate?
Thanks for the assistance
My take is that the feed rates are based on the density of material you are cutting and the bit you are using. I’d opt for a new bit and slow down both the depth of cut and feed rate and see how things progress.
Flex is also a problem and I’ve had good success by adding riser plates,stiffeners, extra extrusion, and 9mm belts, as well as an aftermarket Z axis.
Thank you very much for the advice, Martin.
If it is only happening on denser materials, then your feed rate and/or depth is too much.
Just like hitting deep snow or mud without enough ground clearance, your steering is greatly reduced, and the vehicle continues based on physical factors, not on intent or where you tell it to go.
The cnc is similar in that the weakest point will fail. Harder woods are stronger than the rubber belts that want to guide the bit, and the deeper the bit is into the wood, the more resistance there is to the “steer” command.
Slowing down the feed rate allows the bit to clear the material more effectively before continuing forward. But with denser woods, you may also need to reduce the depth per pass or increase rpms, or both. I do very different cut settings for different woods - Just as a loose example, I have cut the same file on mdf at 300mm/m and 0.7mm depth per pass with no issues, but on zebrawood I did that file at 100mm/m and 0.3 depth per pass.
Thank you very much for the tips, Jordan.
I have ordered a new bit too!
I will try all these new settings.
If you are running the stock steppers belts and pulleys I would suggest upgrading. I upgraded a couple of years ago and never regretted it. No more chatter or jumping around.JAT
