-NOTE: These have been changing as we work out how the speed/layer height and flow rate interact. ​Latest idea is a lower flow rate 90% or less, and then balancing ​speed with layer height - need to use slower speed for larger layer height because each layer needs more plastic. We think that the hot end is slightly blocked and this is causing variations in the flow. For most prints this isn't noticeable, but is causing some problems for overhangs and prints with openings. The latest setting are on the iMac in the upstairs entry.+NOTE: These have been changing as we work out how the speed/layer height and flow rate interact. ​Balance ​speed with layer height - need to use slower speed for larger layer height because each layer needs more plastic.

-* our latest guess is that the having feed rate too high causes blocking in the hot end which means variation in the flow   +  ​* extruder grinding instead of feeding the plastic - see above for adjusting the extruder. (might be caused by high flow rate)
