Layer Test Print Strike 2
With the relatively thin Probe 6 fitted, a new slide was inserted and all axes zeroed, together with Z Touch.The extrusion width in PrusaSlicer was adjusted to "1.5" (15μm) and the test "Lollipop" printed. The first layer printed perfectly, however the layer height was set to 10μm which proved to be too high and subsequent layers did not print. Images here taken at a 70 degree angle to give some impression of depth.
A 200μm hollow cylinder with 2 solid bottom layers was designed as the next test object, the "dipify" script modified to expose the resin to UV briefly during dips to stop the resin running around, and the second attempt was made to print. This appeared to create the first 2-3 layers, and the bottom infill can be seen:
The extrusion width was lowered to 14μm, layer height reduced to 5μm,and another attempt made. For reasons unknown, only one layer printed. It is incredibly difficult with current optics to tell if layers above the first two are being successfully deposited.
It appears that the software modifications are useful, but Probe 6 is too thin to hang on to a decent amount of resin.
Next steps:
- Put dipify code on github.
- Make another slide.
- Make a slightly thicker probe.
- Retest.
