Shipping Damage - Possible Fixes?

(I already sent a message to support about this last night, but wanted to ask here just in case the community has any ideas.)

So I ordered the fully assembled, calibrated, etc. printer to get back in the game - I've built a 3d printer in the past, but ran into a few too many issues and stopped printing a while back. This one made it all the way to the states and to my local sorting facility, then suddenly stopped moving... and instead a package from "Corporate Overgoods" said it was coming to my house...

I know there's potential to file a claim, but I figured if the damage wasn't major it might make sense to just repair it.

As I inspected it I noticed a few points of damage: the front loop of the y-axis belt had popped off, the end cap on the y-axis rail (on the x = 0 side, next to the control panel - photo below) was busted out a little, and 2 of the 3 zip ties on the y carriage were snapped.

I fixed all the damage I saw, and at this point I've done some manual checks, and it appears that the majority of it is still OK:

  • All 3 axes travel appropriately (i.e. using the manual movement options under settings makes each axis move a matching distance).

  • Homing the nozzle works fine - everything zeroes out and the PINDA finds the first probe spot just fine.

  • X and Y axes appear to be square, or at least close (within 0.25-0.5mm over the course of the x axis - close enough that it could just be me moving slightly as I scan up and down the x axis).

  • Settings temperatures, fan speeds, and running the extruder all work fine.

  • Checked that the y-axis gear is tight to the motor.

    • Couple wonky bits though:

  • The rear right of the build plate (marked as x and y in the 200s - near the last calibration point) reads about 1mm higher than the front right according to my calipers (took a measurement at y = 0, moved the plate to y = max and took another measurement at the same location in relation to the printer; so table surface variance isn't the cause).

  • Running the z auto-calibrate from the settings finds the first point perfectly fine, and slowly shifts more and more off for the others. The x axis seems to be spot on for the points, but the last point looks like it's at about x215 y195 to y197 instead of x215 y193 (i.e. 2-4mm farther back than it is on the first point).

  • Not sure if it's entirely related to the calibration points, but it seems to be having a hard time finding points 4, 5, 7, 8, and 9 - which causes it to push into the plate as it tries to calibrate to them.

    • I've checked that the y frame is square as best I can while it's built and it seems to be fine - similar to the x/y alignment, any variation is very slight and might just be me moving slightly as I look. I've also retightened the belt, made sure the x-axis is perfectly level to the build plate, and checked the rest of it for damage (except for opening up any of the electronics).

    I can't quite see it being the y axis being un-square - everything was super tight when it arrived; so if it isn't square I'd expect it to be that something is bent, which I won't be able to fix. Since it was the built and calibrated one, I also know it was working perfectly fine before it left Prusa last Friday (the 2 color Prusa logo was still on the plate and looks perfect).

    Any ideas?

    (Outside of debugging / small rant: Gah shipping companies. It's frustrating because this was also going to be my daughter's first exposure to a 3d printer or any sort of robotics; but instead someone at Prusa's time was basically wasted from it being knocked out of calibration, and my time is being wasted doing diagnostics and debugging. Half tempted to file the claim just to recoup the time costs even if I can get it back in working condition.)

    Hi Paul

    UPS is usually a great shipping company and I think you are the first to post on these forums about shipping damage, but mistakes do happen.

    The problem here is that this is a precision instrument and any damage of this type can cause issues with printing - which you obviously don't want, having bought a pre-assembled printer.

    The problem here is that we don't really know how much damage has occurred not how fixable it is (there may, for example, be a bent rod).

    I really do think that you should make a claim and get a replacement.

    Peter

    Thanks Peter,

    Prusa got back to me with the same thoughts, and will be going the claim & replace route.

    I normally don't have issues with any of the major shipping companies (UPS, FedEx, DHL, regular postage) to my home address, but I've seen a fair amount of entertaining damage at work from pretty much all of them - it's ultimately all just people and people make mistakes, which is understandable, just frustrating on something like this.
