Looking for anyone whos used a drag bit on their MPCNC for acrylic or metals.
Hoping to learn how to set this up in Estlcam, tool setup, speeds, etc. Lessons learned…

Oh, That’s cool. So you can just chuck it into the router (without turning on the router) and it will scratch off some paint on a soft surface. That’s neat.April 27, 2017 at 12:01 pm #32294
Very cool. I would guess you could do a typical engrave “on line” – Possibly set your bit just above the surface and start with a shallow depth of like .5mm and go from there. Would be interesting to see if you could score glass with this and snap it out (obviously not much more than straights and angles).

Here is a short video of the MPCNC with the diamond drag bit on 1/4 plexi.

MPCNC is not as good as an American quarter. /Troll
@kris, that is awesome. Do you have any tips or techniques?April 28, 2017 at 7:34 am #32344
So I have not tips or tricks.. but what I have been told is you are to use cast acrylic.
I am merely messing with Plexi as that is what I have available.
I was told to do the following when setting up the bit/etch: Lower you router or whatever you use until you sink half of the spring travel onto the workpiece. Then set you z at 0. I cut all my etches at .01 “. You will not miss any vectors that your software has created by doing this.
I am not entirely sure how to do that… I am going to give another try by going down 5mm which is about half the spring travel.
Though on this next test in Estlcam I have it set up as a carve and when I load into repetier the V seems to have some gaps and I cannot figure out why this is…

That looks like a display artifact. The shape is totally different too, so I wouldn’t think it’s a gcode problem.
