As the Velleman video shows the K8200 printing the gyro cube, I thought I would have a go…
My first few attempts failed early on due to not sticking down properly.
I sanded the bed and changed temperatures and brim, but in the end, my main issue seemed to be having the calibrated Z=0 height too high. Lowering the head seemed to help - in fact it was difficult to remove when I was running at 60C bed temp, so I’ve gone back to 50C.
The next attempt failed with a blob falling off the print head - note to self : make sure print head is cleaned after failed rats nests
It looked like it was printing, so I left it over night only to find it failed about 3cm up, so the rest was a rats nest… I really wish something like Filabot was available, so I could recycle all these failed attempts…
On examining I could see the occasional slight dislocation of a layer. This wasn’t the big dislocation I initially had, which I think was X belt being too loose, but more symptomatic of a stepper miss, so I increased my driver voltages to 0.65V and tried again.
It almost worked
The two broken sections were caused by the head hitting the part (both on the same bottom left side) hard enough to snap them off. No idea what caused this… slight difference in cooling perhaps?
However I left it running and after 13.75 hours I got what you see in the photo.
Lots of trimming required and only the inner cube moves.
Anyone got any suggestions on trimming prints and freeing them without pressing, as the shell cracks easily?
