I think I finally sicceeded to fix my 3D printer. The combination of clogged nozzle and a corrupted test print file really made it hard to find the issue.
Trying to print four plant pots... soon I'll know wether it went well or not.
i want to add pH and EC sensors and possibly even two more pumps to automatically control pH value and nutrient saturation.
also might add plant lighting and sell this to all the indoor growers i know
