I am trying to print these pucks all about 1 inch tall. The external fill pattern is set to concentric but the preview shows incomplete circles. I looked at the gcode and found out why: extrusion stops for the last few lines of each layer, causing the circles to not connect. The whole program is over 30,000 lines long so I really want to fix the problem at the source rather than inserting an E value line by line. Anyone know why this is happening?
