OK so I haven’t been here for a while, turned out the board was shorting out, so my Architect has been off for a while. But yesterday the engineer arrived and we spent a total of 5 hours in repairs.
The first print after a rewire went really well, only detaching from the bed stopped it being the first successful print. So a little hairspray later and the second print came out. Uh oh - the old shifting layers problem. The engineer realised what this was straight off, and reduced the current to the board. The board was heating up and then not performing as it should. The next print had none of the ominous noises of before - cured.
So rather than leave it there, time to make sure the second head worked. In the third image you can see how well that went. Turns out that the second nozzle was occluded from the fan by the way it had been wired in. Cue a rewire of the head assembly. Second head then started to print clean.
Cue 4th print. A success! My first finished print. The quality is down to my Cura settings, but then, that is what I expected to be tweaking weeks ago.
So the engineer left after a very long day for him.
Naturally I then tried printing again. Oh dear.
In the last set of photos you can see that the print stops. And by stops I mean the nozzle stops, everything else continues until you have this point where the head is moving and the filament is being pushed but nothing is coming out.
Could it be I still have to drop the current further? Attempting another print this morning to see what happens with a “cold” machine.
