I’ve changed the gear and it stoped again.
How do i check the cables?

Move the extruder around or sway the cable chain gently to check whether temperature on screen changes a lot or not.

Hi,
I‘ve changed the cable yesterday and it doesn’t work. Print stops again after about 2-4h after beginning.
Anything else I can test?
It would be really important to get the printer running again as fast as possible.

Hi Vicky,
Moved the extruder around several times.
No change in temperature and the left extruder although shows the same temperature like the left one.
Yesterday I have changed the spool and it printed for about 28h before stopping to extrude.
I could pull the filament out of the printer easily and it didn’t looked like clogging (as seen on the picture). Could it be the motor? Ore an Bad thermocouple ?

Now I’m using 240C and an new nozzle.
But the filament can be pushed out easily and although pushed and it extrudes.
What have I to do?
I’ve already adjusted the gear.
(By the way dose sb know how to get the used gear
Off easily. It was quite an hard thing to change.)

Do you mean that you can push out the filament to continue extruding easily after no extruding?
Which means either the gear is too far to bearing or the teeth of gear is washed.

I what bearing do you mean?
The one next to the feading gear, wich pushes the filament agenst it?
And yes I can, with a little bit of force, pull the filament out. Or push it and the then it continues extruding.
Something I noticed is that I can pull the filament out of the extruder while the gear doesn’t move, but on the filament I can see small dental impression.
But the thread of the part that pushes the filament agenst the extruder bearell is used down tho it moves a little bit to the left while extruding the filament. And i’v forgotten to mention that I get an perfect first layer (why do I get it and it doesn’t stop immediately after using the left extruder?

would it be possible to get the
3D files for the extruder head, where the motors are placed, ? Tho I would be able to manufacture an spare part by myself.

Actually we leave a little space for customer to adjust the gear position.
You can loose the fixing screws of the extruder motor and move it a more close to the feeding bearing beside it.
To secure the position, you can insert some paper or other thin stuff as shim at the other side to the bearing.

Actually the pictures had been taken with an 3mm sheed of aluminum. But it didn’t work.
But I guess it isn’t possible to get those files?
It would be me a fafour to manufacture the spare part to have an long lasting solution

I'm so sorry but those are internal files which are not allowed to share with public. If you want to know some key measurements, I can ask R&D team to help confirm.

While I fully recommend the Bondtech, there was a step skipped in this upgrade and adjustment process.
Something as simple as replacing the gear wheel on the motor to one with sharper teeth might help here for a fraction of the cost.
viewtopic.php?f=4&t=6193&p=24902&hilit=sharp+tooth#p24902
Example here is these grip better than any other single sided drive gear setup because of the tooth profile https://www.amazon.com/gp/product/B06ZYG5Z47 Now yes, that's a 4 pack, but it's the only gear on Prime I know is the "correct" gear. Other look alike and are not the same profile and there is a difference.
If you can stand to wait, you can order just one or 2 from here https://www.3dp2go.com/38-teeth-steel-e ... p-450.html

Hi,
I’ve talked about the bond tech with my employer and hopefully i’ll get it in the next weeks.
