Hi all,
Sorry if this is a rookie question, but I have had a recent consistent problem with my A1 printer in that it consistently reads the plate as being lower than it actually is. It seems like something that grew as a problem over time. There was a single part I was printing many times and the parts gradually grew worse and worse.
I have tried all the usual suspects, recalibrating many times, swapping out the hotend, and cleaning inside the area where the hotend is placed. A while before this I did have a big glob of filament get inside the silicone sock, which I cleaned the best I could. The clamps for the hot end are a bit stiff now, but it doesn’t appear to impact their seating location at all. I’ve looked at the eddy current sensor, but I don’t see any sign of damage, and the wires appear to be intact.
When I home all the axis the tip of the hot end is touching the build plate, you can’t move a piece of paper under it.
As you can see above the first layer always comes out bad and the rest of the model typically has a “squished“ look to it.
Any ideas as to what might be the problem or any workarounds would be greatly appreciated.
Many thanks
