Different Prints Failing at the Exact Same Height
The printer was printing fine for weeks until it crashed into a print. I inspected and recalibrated then ran a Benchy to test and it fails at the exact same height. After making sure the nozzle was fully seated, checking the pinda height and inspecting for obstructions I tried another benchy and got the same results on the exact same height. The Z screws are straight and not touching the top plastic parts. It prints perfectly up to a specific height then knocks the print off the bed. No idea where to go from here. I'm using PLA on an MK3+. Any thoughts would be appreciated!
I haven't printed a benchy and watched at the exact time it crashes but I do know it knocks the print off the bed. Tomorrow I can reprint a benchy and film the exact moment of impact if that would help.
Please show us the underside of a failed print.
Cheerio,
RE: Different Prints Failing at the Exact Same Height
Here's a look at the first layer. The print quality is good up to the fail point.
That looks slightly odd. The first layer is going down well but - what is causing that splatter pattern of discolouration? It it poor adhesion due to something being spilt/sprayed nearby?
Try giving the print sheet a thorough clean, see if that's enough.
