temp towers malfunction

[jmiller1111]

Hi All,

I tried to make a temp tower for PET-CF. The machine only goes to 300C so I input 280c thru 300C, at 5c increments, for the tower specs.

When the tower prints, the bridge will print the outside lines slowly, on opposite sides, in groups of 5 lines. There is a large gap between these two sides of about 12 lines. When the print head goes to print the inner gap, the print head will increase to normal speed and proceed to squirt filament all over between the two correctly formed outside lines of the bridge.

Pics attached. Any idea what I'm doing wrong?
