    So i'm having more problems after i tightened up both belts pulleys. My prints are wavy only on the Y axis which makes me figure that it's my X axis that is loose or not returning to the same spot. I can not figure out what is going on here any suggestions? May try to slow down my acceleration some more but i feel like it's gotta be something loose that's causing this, right?

    Here's some terrible pics but you get the idea

    That is a loose dive component on whichever axis is affected.
    It is not always the belt, sometimes it is a loose drive gear.
    Check the set screws on the sprocket on the motor shaft.
    I would suggest you check them all and use Loctite.

    Printed this last night and it seems to be good. I'll check my set screws again but I'm lost. Am I correct in thinking that since it's printing funny in the Y direction it has something to do with my X axis being loose? The X axis seems straight so the bed must be coming back to the same point every time.

    Thanks

    Is this an R1 or an R1+? (Those waves look a lot like the Z axis 'waves' that the leadscrew upgrade is targeted for.)

    If it is off only on the Y then the Y is usually the one to investigate.

    It's an R1 with the poor man's lead screw upgrade. Couplers with cheap leadscrews.

    Maybe the Z couplers are loose?

    Probably check that when I'm off work because I've had one come loose before

    Couplers are largely the culprit* for the Z waves in the first place :)
    That is why they eliminated them.

    Absolutely they could be loose. Worth checking.



    *this is a gross simplification, but if you really want to dig into it the threads Ziggy had are the best resources and have a very detailed analysis.

    I bet that's it. I will loctite then up later tonight. Weird that a test cube prints up fine but an 18hr job looks like crap. Guess I shouldn't have cheaped out on the upgrade.. maybe I'll just buy the official ones.

    Thanks again for the help.

    Good luck. I have two (originally betas) here and one has the Z axis upgrade(and the bed upgrade) and the other not.
    The difference is noticeable on larger prints, but not enough of an issue to bother me on that printer since I just use it for larger/faster prints (it has the 1.2mm volcano on it). The other has a 0.25 on it and does any detail work.

    By the time I sand and paint anything that comes off of it (assuming that something is a 'keeper' and not a test) you can't tell.

    So I tightened everything up I could think of, nothing seemed loose, and printed a solid test cube. I'm thinking that it's the actual volcano hotend shifting around on me. Going to print a new bracket for it to mount to and see if I can get it any tighter. Don't the new R1+ use a screwless design to hold the hotend in? I think my e3d came with the aluminum piece to hold it. Is there anything out there to print to use that?

    Thanks, I think I'll need the carriage and stuff. I have a couple of those brackets I think would work.

    Well so I didn't start a new thread.. any suggestions on squaring up my X and y axis? Something's going on. Going to try it apart, loosen the bearings and try to use a square I guess. Frustrated...

    Leveling the x to y? I do a paper leveling. As square as it needs to be :)
