Hi there! I just entered the 3d printing world and I’m setting my Wanhao i3 plus. When I try to setup the step/mm I send a gcode file with 150 mm of extrusion and I get something around 81mm. Really big difference. I use the formula (starting with the default value 94.30) but any value doesn’t seem to affect. I get better results but never the 150mm. I changed the step motor of the extruder but is the same. I check the vref but it’s ok. Any advice? Thank you in advance! Cheers
