Infill speed slow?

[highlea 2]

I am using Cura 15.02 and an Ultimaker 2 Extended with the following speed settings:

Print speed: 60

Travel speed: 150

Bottom Layer speed: 30

Infill speed: 100

Top/bottom speed 30

Outer Shell speed: 50

Inner Shell speed: 80

Material is ABS and using a 0.8mm nozzle with 0.2mm layer thickness and infill set to 100%.

When I watch the print, the infill looks slower than the inner shell speed.

Has anyone else seen this problem?

Thanks

For solid-infill layers I would expect it to be at 30mm/sec which is slower than your other speeds. For the grid pattern it should be faster.

There is an acceleration factor also. If you are printing long straight lines (say 100mm) it can get up to 80mm/sec but if you have short segments it might not be able to get up to speed.
