First layer too high
Posted: April 4th, 2018, 7:21 am
I am a rank beginner in this field using a Maker Select V2 with PLA. First 2 prints that were on the Micro SC card came out perfect. Next, I printed a part we modeled in Fusion 360 and sliced in Cura which also came out perfect. I did a few more prints of various things then switched to PETG. I could not make the head go all the way down to the bed. The menu says it is .3mm above the bed. After a couple of days and several various attempts to resolve the problem, I realized the Z-axis limit switch was engaging and not allowing the print head to move low enough. The switch is not loose and nothing mechanically has changed that I can discern so I have no idea how it managed to print the first models. Out of desperation, I parked the head at the lower limit then raised the bed till it touched the nozzle. I then leveled the bed using a standard piece of typing paper. No matter what I do it refuses to go below about .3mm. I tried setting the first level in Cure to .1mm, same results. I even tried a negative number but Cure refuses to slice it. I figure it’s something simple but it is apparently above my pay grade. Any suggestions would be most appreciated as I can find no help on a couple of other forums.
