Hi all,

i have an issue where my x-axis tilt to the front (see red arrow on photo). The reason is that there is a small gap (1mm) between the last wheel and the rail of the Y-axis. this is on both sides of the Y-axis. 

I've checked everything and everything is screwed tight. is this due to my 3d printer? is there a way to fix it? (redrill the holes maybe?)

thanks for the help.

regards, Alexander

no one had the same issue? 

Thanks

Just re-read your post, so you have  1mm play when you push the x bridge to the front? If so you most likely have to play with (less thick?) shims on that carriage. I printed several sets of shims and played with them, adding more then more till the fit was tight... I hope this helps, if I misunderstand your issue pls explain differently. Thanks! 

Hi Dany,

thanks for the reply.

the issue is on the Y-axis (see photos in first post). I understand you that I can increase the distance by using less or more shims. however i dont use shims on the Y-axis and i need to make the distance smaller.

i will try to reprint the parts. 

Yes I now see that on the first pic. Interesting... I could not have assembled mine without shims! Maybe Check your wheel size? Are they the same diam as the ones used by Topsie?

Do you have any remaining print 'debris' where pieces join, which would act as unwanted shims? Are your 4 feet the right size, do the 4 strengthening horizontal "H" blocks connect to the rails without bending those? I am puzzled... Good luck

Hi Guys, I'm currently printing the parts and the pictures above drove my attention, so I didn't yet print the bottom ones.. I'm waiting to get both the wheels and the aluminium profile from the vendors to figure this out.

I was wondering if the machining of the vslots was not the source of the issue.. Just a thought, because I believe that milling the slots as Topsie has shown is probably removing a couple of millimeters to the overall thickness between bottom and top wheels. This could explain the tilting effect, but I may be completely wrong here.

Aha!

Yes you're probably spot on. Didn't think of that as I bought already slotted ones. So how can you fix that? Sandpaper on a flat surface the carriage elements is one that comes to mind, or reprint adjusted ones. You're getting there! 

Hi all,

Sorry for the late replys, i have been busy.

l could not find the cause but to fix the issue, i have redrilled te holes 1mm higher and now it is a tight fit.
