Topic: S3 weird behavior after flashing firmware
I replaced the stock extruder/hot-end with with an E3D Titan and Lite 6 on the S3 printer at Milwaukee Makerspace.
I updated firmware using Solidoodle-Marlin_v1-Solidoodle_Marlin_v1_beta In config.h I specified S3, selected board 81 (printr board rev E), and increased temperature limits for hot-end and bed.
Result- New temperature limits work fine. When printing solid infill it prints every other line twice in the same place and skips the adjacent line, leaving gaps in the fill. The nozzle moves across the part, printing a line, then shifts for the next line, then shifts back on top of the line it just laid down, comes back, shifts to the next next line and repeats. The brim and perimeters look OK. Video here: https://vimeo.com/173202575
When printing rectilinear infill at 20% (only value I've tried so far), lines are spaced unevenly resulting in rectangles of varying sizes, not squares:
I tried slicing with Slic3r and Cura and while the tool paths change, the behavior remains the same. I am using pronterface for host on computer running Ubuntu 14 LTS.
