I have an 8 inch height build area. The last picture is the part that I am testing. It’s a wing nut. My z-assembly is very loose and not rigid. Due to my limitations on printing volume, I was not able to print the rigid middle z parts. I am attempting to print it tonight with the extra support on the frame. I am noticing random blobs about 5 mmm long and 2 mm wide after the first layer is complete.
The extruder was bought from you, my motors are similar to your spec, I think the voltage is a bit lower on mine. I am also using the ramps just like your parts list.
Right now I am using hatchbox pla filament.
I will try the spiral vase after my last attempt here for the night.
