RE: HOMING ISSUES
What I meant was, the belts, the flat side of the belts have to go together; they slip easily therefore it will reduce the 10-12 teeth to 3-4.
That it not correct. When you form the belt loop, it is the toothed side of the belt that touches the toothed side of the loop end. This is the only way how the two can interlock and stop the belts from slipping.
It still seems very likely that you form the loops incorrectly. Please look closely at the photos hyiger and I share above. And please post a photo of your belt attachment.
RE:
if you look at the holder plate from the side that will touch the linear rail you see that each belt has 3 holes. The belt right and left side will indeed enter the center hole with the flat side touching, as you show in your last picture. Then each side need to go into the holes left and right so that their toothed side will touch the toothed side of the incoming belt. Tooth will interlock, when pressed agsinst the linear rail it will become nearly impossible to pull the belts out.
if you do not post a picture of the plate ready to be screwed onto the rail, there is nothing more jürgen, hyiger, me or anybody else can write to help you.
RE: HOMING ISSUES
I decided to read up on another troubles they have had with the belt and getting it work with the nextruder holder. Therefore here is some of my most recent picture; at this point I have the belts though but getting 4-5 teeth though the holder for X-axis & Y-axis and getting them to stay, that is the most difficult.
One more suggestion. Looking at your earlier picture, it seems that you first inserted all the belts, then tried to form the loops for each of them. That is not a good approach: Before the loops are formed, there is nothing which holds the belts in the Nextruder plate. As you have experienced, they will slip out very easily.
Instead, insert only the first belt end, and form the loop (back through the neighboring slot) right away. Then this belt is already held in place by its interlocking teeth. Next, insert the next belt and form the loop -- and so on.
RE: HOMING ISSUES
If you look at how the belt is suppose to be inserted; there are two flat parts for the X-axis & Y-axis that is how the belt loops around into the harness. Is it this part to which the belts slip out. I understand how it should work the teeth lock with the other teeth on the belt, although if it locked in place as so that I could get the other parts of the belt to look that would be fabulous, but it always slips before screwing it down. Although I gave it more teeth this time, with the expectations that some will slip, I can hope that this works.

As mentioned before: The picture you shared suggests that you have inserted all four belt ends loosely, and then try to form the four loops in the next step. The loose belt ends are bound to slip out, because nothing is holding them in place.
Please try to do it one belt end at a time instead: Insert the belt end, form a loop with 4..5 teeth -- it should stay in place on its own. Then do the next belt end the same way. Before you work on each end, just let it dangle loosely.
RE: HOMING ISSUES
The X & Y belts both have a teeth end and a flat end, that's how belts are designed most of the time unless they are double teeth on either side. What I'm saying is, and I have done exactly as you said but that doesn't guarantee that the flat parts of the belt when rubbing together won't cause the other part of the belt because they are flat for either the X belt or the Y belt from slipping out giving less teeth then that is needed.

What is the current state of your assembly? Please take a photo and share it here.
- If you have already created all the belt loops and screwed the plate back to the gantry, but have not mounted the Nextruder yet: Please take a photo of the installed plate with the belt loops.
- If you are still in the process of attaching the belts one by one: Please take a photo of the current state, even if it is incomplete.
RE: HOMING ISSUES
The current state is this; https://forum.prusa3d.com/forum/postid/772511/ as it has remained.
RE:
But did you read and understand my two prior posts which suggest that this is not a good starting point?
You have inserted all four belt ends, but nothing holds them in place. As soon as you start working on one end to try and form the loop, one or more of the other ends will slip out. Do not start by inserting all four ends as shown in your photo.
Instead, focus on a single belt end first: Insert it and complete the loop. That will hold it pretty securely. Only then take the next free belt end, insert it and complete its loop. Etc.
RE: HOMING ISSUES
I tried exactly what you mentioned, the belts still slipped. It's not an easy process, others have mentioned the same thing in the comments for assembly. Although, there is no other way to do this but either the way I showed in the picture or, one by one as you mentioned. And hope that 3-4 teeth lock with the other teeth on the belt and hold. Otherwise, when inserting the other end of the belt; whether X axis or Y axis the teeth could slip.
I tried it all, it's very tricky. Then again, if you do manage to get it and screw it on you see a belt slip out; back to the beginning.

My point is that the two approaches are not equal. Doing it as you show in the picture is bound to fail. Doing it one by one has a much better chance of success.
Please try it again, with the "one by one" approach. You can also try and secure each loop with a bit of adhesive tape right after you have formed the loop. (Scotch tape or such, taped over the back of the mounting plate to hold the loop in place. Just temporarily, while you are working on the other belts -- before you screw the plate onto the X carriage, remove the tapes carefully.)

I am an older person, but in my entire life I have never seen anything as stubborn as you. I don't know how old you are, or what your education is, but this nonsense is already beyond all limits! Several people are trying to help you, showing pictures of what the belt guide should look like, but everything is in vain! You are simply doing your own thing! Do you realize that tens of thousands of printers have been assembled without any problems, only you are constantly doing your own theory. Have you not yet understood that you are supposed to insert the ends of the belts back through the nearest hole under the metal part so that the teeth on the belt lock into each other? And whether there are 4 or 5 teeth doesn't matter that much. The ends of the belts MUST NOT BE SEEN after being screwed onto the X-axis carriage, because they are hidden behind the metal part! And you probably didn't understand that THE METAL PART IS SCREWED ONTO THE X-AXIS CARRIAGE ONLY AFTER ALL THE BELT ENDS HAVE BEEN PLACED! First of all, unscrew and remove the metal part from the X-axis carriage and go through the entire assembly procedure again step by step and follow it exactly (and when I say exactly, I mean down to the last detail)!

There is only one way to do it right! If you use the other one (yours), it will definitely not work! So for God's sake, do it right and don't jump on anyone here! You are the last person who could complain about anything or anyone here!
RE: HOMING ISSUES
What does that mean, I'm the last person who could complain about anything or anyone here ?
Do you know exactly how everyone did this part of the assembly ? No you don't. Therefore how can you say that my way is just disastrous, you can't. Unless you can read minds which I doubt.

RE: HOMING ISSUES
@butters, please face the facts -- it is very difficult and frustrating to help you.
- You always seem totally convinced that you are doing it right, to the point where you do not even read suggestions or look at pictures with an open mind.
- You never acknowledge that you have understood a suggestion to do something differently; you only dig in your heels and state that you are already doing it right.
- Eventually you disappear for days or weeks, and then maybe have fixed the problem. But you never confirm that you did, or what you did differently than before. Let alone thank anyone for their help.
This is not new behavior. I remember your endless questions about a Philips screw, and your recurring issues with the frame profiles. I kept coming back into your threads to help you anyway.
But at this point, I must assume that you are just trolling us. I will stay out of this and any future threads. If you want to convince me otherwise, please contact me by personal message.
