    @Phaedrux ok, but I tried to move it manually without the belt to see if it was free and so it was, do you think the bearings need to be changed?

      Well the real question is does mesh compensation work to produce a good first layer?

      Do a test print once with mesh enabled and another with it disabled. You should be able to tell if the mesh is accurate or not.

        @Phaedrux ok I will try in the meantime I disassembled the x axis turned the bearings
        "just to give it a try while I was waiting for some advice from you" and now I've reassembled it and put it back to making a cold mesh to see if anything has changed, then I'll try to print to see if the mesh works or not, tomorrow I will post the results with and without mesh, for the moment thanks @Phaedrux.

          @Phaedrux looking at the graphic mesh and checking the coordinates of X which are spaced by 20mm, in 60mm the wheel should make a full turn, I did a free test: I lowered the probe stem I raised the Z axis until it touches the flat, at this point I moved the X axis by 60mm and about 30mm it raised and then lowered in the remaining 30mm, you know you were right the bearings are gone

            have you decided what to do about it?
            new bearings or linear rail conversion?

                @Veti converting it would cost me time would i have to create the pieces and have them made

                  depends on where you live
                  A good place to start are the original openparts store
                  https://openbuildspartstore.com/metal-v-wheel-kit/
                  https://openbuildspartstore.com/ball-bearing-625-2rs-5x16x5/
                  (check that the size is the same as yours)

                  alternative these are recommended for the voron 2 printer and are supposed to be high quality
                  https://www.aliexpress.com/item/32991204773.html

                  look for high quality bearings ABEC-7 or above ( ABEC-9)

                      @Leblond said in Triangular wave and print area:

                      converting it would cost me time would i have to create the pieces and have them made

                      the parts you can print yourself.
                      eg (there are many others for the troxy)
                      https://www.thingiverse.com/thing:3855641

                      the rails would need to be ordered

                        @Veti forgive me but it's not for the printer I have, my printer is a tronxy but the X5SA Pro

                            o god. the x5s pro is even worse than the original one.

                            and those wheels dont seem like the openbuilds ones.

                            what bearings do they have?

                              @Veti 😲 I assure you that you are wrong, the bearings are "u" groove, I have to disassemble them to see their dimensions
