Between here and eBay I have sold out of my first batch. More coming in Wednesday the 21st of March.

Great info guys! Thanks. I am curious about the results given by a plasma cutter. I understand that it wont be as good as a laser, but I talked to a guy who runs a CNC plasma cutter in a small industrial concern that cuts sheet that doesnt require any close fitment and he really talked lowly of its ...

Non SO machine

3.175mm endmill 2 flute
DW660 tool stuck at 30k rpm
400mm min cutting feed
Long ramps into cut
0.5mm depth of cut
Those settings made a nice piece for me in quarter inch 6061 plate.

No need to apologize. I am enjoying the discussion. You list some good info. I will openly admit that my settings are non ideal. Before anyone bucks the trend and adopts my settings they should know that I usually am cutting items that dont require much precision. I am just interested in getting the...

TDA, I appreciate the discussion. I agree that things aren't ideal with my settings, but I submit that the kind of machines we are using just force into work arounds.

I dont have an SO but I have built one with a belt driven Z in a luff tackle configuration (so a lot of back and forth on idlers. It seemed to matter somewhat where Z was in its travel when I tensioned it.

How long is the span where you can push it 8mm? Its just too loose I believe.

I understand the point that you are getting at, but lets look at it this way. Suppose your small depth cut is indeed better for longevity of the engaging portion of the flutes given a particular linear footage (I grant that it probably is). I engaged my cutting surface one time. You engaged it 6 or ...

I agree that 24k was probably too fast but I was trying to get him as close as I could to my proven settings, and I am stuck at 30k. I disagree with many shallow fast fed passes. Slow the feed a bit to keep the forces acceptable, but put that bit in the stock. Millimeter and sub millineter stepdowns...

I cut birch ply nearly every day. Im stuck at 30k rpm with my dw660. I usually go about 1300 mm per min at a 6.3mm depth of cut with an upcut. I usually just use a downcut if I want to run some engraving with the flat endmill, but I have just cut it profiles with it if I dont feel like changing Why ...

Glad it worked out for you. That is much more inline.
