Ultimaker S5 prints not square

Recommended Posts

Posted (edited) · Ultimaker S5 prints not square

So i have had two S5 printers (one was replaced as it was damaged in delivery but i managed to get one print off it) and it appears they both have exhibited the phenomenon of the prints not being square.

 

The print from my first printer (i dont have a photo on me for evidence) can be seen by eye to be very slightly not square.

 

Attached you should find a couple of images of an item i printed last night. this needed to be quite precisely square but as you can see, it is not (i added some right angles to the image for clarity). the second image also shows that the print has bowed vertically. has anyone else seen this or do you know why this might have happened? i had a look on google for answers but didn't find anything quite the same so apologies of this has been answered before.

 

Edit: This was printed using ultimaker grey abs on recommended settings and 0.2 mm layer height

 

Many thanks

HI, Thanks for your message, yes, i do, indeed this has to fit into another item which is square and the effect is probably worse than the photo makes it look.

Have you already checked if the print head axes are parallel to the main x/y axes? Do you have lateral play in one or more of the axes?

This is a common problem because when UM printers are shipped I think they use elephants to move your printer from one truck to the next.

 

Seriously though - it's a common problem and you just have to realign it - it's pretty easy to do.

 

More serious is if the entire frame is warped so check that the frame is also perpendicular/square.

Dear All,

 

Many thanks for your posts, sorry for my slowness to reply - its is my work printer and work has kept me busy with other non-3D printing related work this week. i will have a go at these suggestions this afternoon/next week and let you all know how it goes.

Hi @wraypa1, any updates on this?

I'm curious if you could also reprint this model in (tough) PLA, see if the cooling properties of ABS have anything to do with it as well (or perhaps emphasize something else).

 

Thanks!

HI SandervG,

 

thanks for the response. I am actually pretty sure that the device came with misaligned axes, following the posts above, i now know what to look for and the axes are out of alignment to what looks like the exact same degree as the print i showed above. i have really only had a few minutes to play with the printer so i havent had time to fix it (the instructions that i found on the ultimaker website arent brilliantly clear). but i will for sure do some of the testing you suggested when i am back in the office.

 

Many thanks

Dear All,

 

I finally had a little time to play with the system and following realignment of the axes it seems fine.

 

Many thanks for all your help.

Great news and I for one truly appreciate the fact that your thread was full circle.

 

Initially you presented a concern and worked through it and then presented the resolution.

 

I dislike threads that do not have closure.

 

Thank you.

Dear Patrick I have just found that my S5 exhibits the same non square issue as you have started the thread about.

Thank you for this and thanks to everyone who added solutions to the issue.

I am going to try to realign the axes over the next couple of days.

 

Best Regards

Tony

Same issue here.  First print job on the new S5 that actually required precise alignment of screw holes.  Spent about 10 minutes scratching my head, thinking my PCB was not symmetrical or was mis-cut, then I check the square on the part and it was off by about 2 degrees.  Printing the larger alignment pegs now (had the 8mm ones already for my 3E), so I will try to re-do the alignment tomorrow.
