Ohai Metalabses! Just updgraded the firmware of our Mendel90 to Merlin_v1_Mendel90 from github. New features include: - Support for centered arcs (instead of polygons) - PID-regulated heatbed (instead of on-off aka "bang-bang mode") - No acceleration/decelaration for polygons (no material build-up at the corners) - Some more features... Updated our Wiki-page with all links to new setup: https://metalab.at/wiki/3DPrinter Uploaded Arduino-Snapshot of the currently running firmware. Uploaded a new slic3r.ini file. The current setup should work for most 3D-models. (I was almost able to print a 10cm high figurine, just some glitches towards the end made it a failure...) Greets, MiKa
