After some help/advice.

The Pneumatic connector has gone on my Omega I3, seems an easy part to replace one would think.

This is the part.

Would this be a suitable replacement?

It looks to be fine, but just checking.

I am not familiar with the printer, but if you turn down the stepper current a little then you might get clucking during skipped steps instead of broken quick fit connectors.
Good luck with the replacements. I did not get an exact match for my quick fit connectors so I had to make adjustments to my 3D printed extruder cold end part that takes the quick fit connector.

Okay, so how would I do that? I’m still pretty new and learning as I go along and have to say this group is 900000000 times better than the FB one.

Did you notice that was for a single connector? I had to wait some for my order (from China), but I got a bag of 10. You should be able to get a 10 count somewhere else for an okay price. If your break one and do not turn down the current to prevent it from happening again, you will break more. At least order 3 just to decrease downtime.

I’ve ordered 5, even if they are wrong the cost is pennies.

I’m interested on finding out how to turn down the stepper though.

I am not familiar with that printer. It is usually a setting in the printer firmware and EEPROM.
Before messing with that, I must ask…did you cut a ziptie that was around the neck of the quickfit connector? The quickstart guide which I read for you says to not cut that. Some printer makers use a ziptie to make the tube stay put.

I didn’t no. What has gone is inside the part is the piece of metal that clamps on. its sheared so won’t hold the tube at all.

Well, you must have ran too fast or had a partial blockage or had the filament hit a ridge in the hotend or tried to extrude when the hotend was too cold. If the hotend was too cold, you might be able to set a safety feature that says not to extrude when the hotend is below a specific temperature. That safety feature might get in the way if you set it to ABS temperatures and then try printing in PLA which may want to print at lower temperatures.
