Bad devices from bad makers are ready to conquer the world!

BadPrinter2 dry run

Yesterday evening we perform succesfully some dry run using a 0.4mm color pen and a sheet of paper on the bed with the Z axis disabled to check the correct function of the coreXY. We select 1/16 microstepping on the drivers and it seems fine and enough (DVR8825 can go to 1/32).

We try different shapes and gcode and now next work is to tweak as best as possible the speed and acceleration. At the moment we are very satisfied with the result. The gear was “printed” with speed of 70 mm/s and 150 mm/s for “non printing” moves; the logo with 100 m/s when printing and 200 mm/s for other moves.

Next step is to check the functionality of our custom designed extruders
