Gravograph IS 8000

[First Sign Master]

Morning all new to the forum welcome all help!

I have purchased a Gravograph IS 8000 great machine was working great BUT now when using as router cutting 1/2" acrylic dimensional letters on three passes each time it gets to 3rd pass it tries to cut to deep yet all parameters are right broke 3 bits already don't understand ????

I have an IS6000 and I've never considered it a "router" due to the spindle being so weak. Mine is all of 90W and I believe their highest power spindle is 200w. Your average CNC router has something like a 2-5kw spindle. My guess is you need to make 6 or more passes instead of 3 to pull this job off. Also keep the kerf clean so you don't get rewelding or burn up the bit too badly.

I think it's a good engraver, but- as rossmosh pointed out- they aren't really considered routers, and you're going to need to make a lot more passes to cut. In my experience with engraving tables (including a Gravograph), you need two passes to cut 1/8" acrylic, so...
