Good to hear! Can we get a picture of the part post-fix?

Here's a pic of my repaired lower guide block x carriage assembly.
I also put a washer under the lower guide block mounting nut so it has more of the carriage assembly to clamp against. Had to file the edges of the washer down so it would fit in the countersink in the x carriage for the nut.

Here's a pic of the crack in my x carriage lower guide block support area.
I am going to put a small hose clamp around the cracked area to secure it for now.

Ouch, ya that looks a little rough.

I used straight acetone on the crack and clamped the broken carriage over night.
Put it back together the next day and have printed about 20 hours worth so far and it is holding up for now.
It solved my rattle too.

I had a similar strange rattle... took me ages to find it. The fan on the extruder stepper motor has a bunch of washers on the two bolts. One of those bolts got a bit loose and it turned into a mini-maraca.

Well my fan's already grinding like food processor so I'll check this too when I pull it off.

My printer has recently developed a rattle when printing and over the past week has become louder.
What I found was that the X carriage that supports the white guide blocks, for the rear X guide rod, has cracked.
As a result there is a large gap between the white guide blocks and the rear X guide rod.
The part of the X carriage assembly that supports the nut for the screw for the lower white guide block has cracked.
I am contacting Support to see what they say.

So if you have a rattle in your extruder carriage assembly check for the possibility of having this issue.

I am having a increased 'rattle' in mine as well and even though the white block seems tight I do see a crack in the carriage near the white block.

I hate to continue grumbling but this just adds to the list of issues that I am having and support replys "we'll get right on fixing your issues", but that is as far as it gets, talk and no action.

I do love using the machine even with its issues but I'm thinking that it will have functioning longevity about the same as the Yugo, and we all (or maybe not) remember those.

Even with all the fun spots, if I had to do this whole experience over again I would pass and look in another direction..... IMHO

I managed to get the hot end cleared and back together, but it wont last another teardown. I ended up buying a new hot end from BilbyCNC. Heres hoping everything works out when I put it together.

I emailed support and they rather helpfully told me to just be persistent with trying to clear the clog. I gave up after trying to clear it for hours and ordered a new nozzle, barrel, heater and some new filament (which i believe was the cause of all my issues in the first place) from a local company who have been very helpful. I cant clean all of the ABS out of the threads on both the barrel and the nozzle no matter what I try. The new parts should arrive on Monday I hope.

We're always here to help. If it didn't work out with the clog, we can always send you a new nozzle.
