So I just pulled this piece off the printer and I’m mostly happy with it. Printed at ultra fine settings on my CR10s pro v2 and I’m amazed at how smooth it came out. But I’m seeing some odd repetitive patterns that I’d like to identify so I can tweak my settings to prevent. In this case I’ll be san…

That is called ‘ringing’ it is caused by vibrations. Causes: Printing too fast. This is in the slicer settings printing at a slower speed may clear it it. Mechanical issues can also cause it, makes sure there isn’t any sloppy ness in the movements. I had to brace my gantry as it vibrated while t…

Are there any good/reliable resources anywhere describing how to adjust and how tight they SHOULD be that I can reference?

That’s gonna be a hard one, Personally I loosen them right up. and I tighten them down until the slack is out and that’s it. I don’t adjust them “tight” at all. Not sure how I could describe it, about the same tension as you would use on a Mayo jar in the fridge, enough so you know it won’t come of…

I set mine so that if I turn one wheel of 3 by hand the carriage will move without the wheel slipping

Here is a look at my x axis carriage wheels. Does all that build up mean it’s too tight? [image] I tried disabling the stepper so I could move it freely but the touch screen button doesn’t seem to do anything. Can I use a gcode command in the terminal to do it? M18 X and then M17 X after?

easiest is just power the machine off, it will allow free wheeling, Just remember not too fast. The dirt on the wheels is actually dust attracted to the wheels cause they build up a static charge. Looks ugly but actually no ill effect as long as you run a Swiffer once in a while.

Learning is fun :wink: I’ll give it a try and see what happens

It feels like there are a couple of spots where it grabs a bit. I loosened the eccentric nut and re-tightened it just to the point where the carriage stops wobbling. I’ll try the ghosting test again and see if that made a difference.

So here’s the latest test print compared to the last one. Used the exact same gcode file. Newest is on the bottom. [image] So it’s marginally worse since I adjusted the eccentric nut. But I’m pretty sure I have a damaged wheel as I could definitely feel a bump/drag when I was moving the x axis ca…

Well that can’t be good… [image]

Nope that is toast. Sorry moose. Yes like others have said. I adjust mine as loose as they can be with out allowing the carnage to rock or twist if you would rather, If you have one bad one you should check the others. I decided for the time and cost to just replace them all. Once I was in it just…
