First, I know…“search”. Second, I have since I got it in May or June. I’ve done everything…EVERYTHING! It acts like it’s almost a pot setting issue as it comes and goes, but is almost always consistent along the X axis when further out on the Y axis from machine home. Everything has been checked multiple times. Still…chatter. I’m planning the linear z upgrade soon, but after the sign I’m working on now, I’m not even sure that would solve it. Tonight I have a sign for my mom that is being carved. Terrible chatter on straight x axis cut while along the y axis about the 7" range. The straight cut along the x when closer to the y axis machine zero is fine. I put my hand on the router, the z axis, the carrier that slides across the x axis and it calms the chatter down. But I’m sure not going to sit and do that. There is absolutely nothing loose, or too tight on it. Everything else is properly adjusted. What the hell could it be!!! This has been a recurring problem since I’ve had this thing. It’s the 1000m version if that matters. https://discuss-assets.s3.amazonaws.com/original/3X/c/b/cb528afa2945271f729f982ad63ac6197cbedeeb.MOV
This is at about .25" on the y axis. X travel is fine, zero chatter.
@LarryM doesn’t matter the settings. I can run at 40ipm, 15ipm plunge and .01" depth per pass with a 1/16" and it does it the same as 55ipm, 15 plunge, .02" depth per pass.
If it did it along both the x and y, then I could understand a issue with router, or possibly being too aggressive, assuming I hadn’t checked or played with either potential issue. It’s driving me nuts.
First, thank you to everyone offering suggestions.
I have actually ordered a 3/4" bit to surface the waste board, but a machinist square says it’s flat right now. In the video is it .02" depth per pass. Does the same at .01" per pass though, that’s why I’ve been thinking it’s not the depth. The spindle to waste board is perfectly perpendicular, the base of the pocket is smooth, with no lines indicating otherwise.
Using a 1/16" downcut Kyocera. This one is probably a bit dull after looking close to the letters after the carve was complete, not sure if that would matter.
Haven’t re-enforced the Y rails YET, mainly due to the fast I was going to wait on that until I upgrade to the linear Z, and get lifted Y end plates.
Belt tension is 3.9lbs all around. When I set it originally after the initial first few hours of use, I set it to 4.2lbs. So, they have stretched a bit. I want to do the upgrade to the wider belts, and at first thought I couldn’t since I have the newer steppers with the pulleys that are secured…but I’ve seen this week where I can remove the pulleys without damaging the stepper shaft. So, new wider belts and pulleys are very soon to be ordered.
@PhilJohnson not yet. All I’ve used is easel so far. Been so busy with stuff I haven’t had much time to mess with f engrave yet. Going to try to mess with it and UGS this week though.
