I’ve had the X-Carve for a couple months now, and my experience has been somewhat disappointing so far.
I got the machine in the beginning of July, and have only had one or two successful carves. The Inventables support has been wonderful, and these forums are incredibly helpful, but I’m still not having much success. I want this to work out-- I have a huge list of projects I want to try!!
When I got my machine, my spindle mount was out of spec, preventing one of the eccentric nuts from seating properly in the extrusion. I filed it down to the best of my ability, but it still wasn’t quite right. This caused a lot of machine chatter, and resulted in a scary situation where the entire z-axis fell off, and the spindle drilled through my work piece, and nearly started a fire (I had run to the bathroom for a minute).
Customer support sent me a new mount and spindle, and very kind, apologetic, and wonderful to work with, but after a month of troubleshooting after getting the replacement parts, I’m still having issues, which I attribute to feeds and speeds.
It seems as though I am doing something very wrong. Even when I am running at INCREDIBLY shallow depths (.007 at 50in/min), I get chatter. Plus, running a job at that shallow a depth means that it takes FOREVER to carve out anything. (Fill settings removing 1/4 inches of material out of a 3x3 inch area took over 3 hours). When I boost up the depth per pass and lower the feed rate, the chatter gets worse, and the job fails.
My 1/8 inch and 1/4 bits are much worse than my smaller bits, but it seems that regardless of what I’ve tried, the eccentric nuts are working themselves loose, and the spindle is chattering during the cut. Occasionally, it even seems like the g-Code for the pass is getting off slightly (the machine will start cutting a line that is off by a centimeter or two. (The deeper the pass, the more worrisome that is, as you might imagine).
Does anyone have any suggestions about calculating feeds and speeds? I don’t have information regarding chipload for my bits, so I’m just doing a LOT of trial and error. But this has been expensive, and my wife is getting annoyed how much time I’m spending with nothing yet to show for it (other than some new knowledge).
I have documented the entire build and prep work processes via video with the intention to teach newbies how to understand and use the machine on YouTube, but until I get the kinks worked out, I don’t feel comfortable putting these out there.
I am committed to figuring this out and making this work, so any suggestions would be incredibly appreciated!! Thank you guys so much!
