Hi all
Have been trying to find the correct surface speed for culculating feed rates for ABS but with no succsess. My router is "slow" max 250mm/min and have tried using both a Dremmel and a Kress router but even at the lowest speed on the bit still get melting and "wavy" edges. most work needs to be with 1mm and 2mm dia mills. Am using air blast to clear chips and cool.
