What infil do you recommend for 3d printing in ABS?

It took a fair bit of trial and error to get a reliable cut without flare ups, here's what I ended up doing (on an Epilog 50W):

  • Make sure the lens is clean!

  • Manually focus the bed of the laser about 5 clicks past the top surface ("into" the wood)

  • Cut the outline of the blocks first, using speed: 20, power: 95, frequency: 500. After doing 2 passes of that check if any blocks are still stuck and do a third pass on ed
    ges that aren't seperated yet.

  • Once all the blocks are free, cut just the holes using 1 pass on each of the 4 sides (again using speed: 20, power: 95, frequency: 500). You can use the scrap as a jig to hold the pieces exactly where you need them.

After that you might need to poke out some stuck
bits but it should work! I'd be interested to hear what procedure @hugs uses - doing a cut for each of the 4 sides does take a while.
