Re: Drag knife.

Thanks Fletcher.
I like that nema14 solution.
It would probably work better in my little cnc router than the Rostock effecter plate :D
The cnc router runs grbl, so I'll check into that.

Re: Tower Rotation Calibration, not 90,210,330

Disclaimer; The following is GUESSWORK, since I have NOT attempted any tower alignment on my Rostock V2. With that said, just thinking through this I doubt that I could physically rotate the towers themselves. I might be able to do something by slackening some things off and NUDGING, then tightening...

Re: Drag knife.

If one wants no offset at all, controlling the blade is necessary. A servo is a good idea, and would work in most cases. But a servo also has a rotation limit. It cannot rotate more than XX°, XX often being a bit more than 360°. That means you would not be able to cut a snail shape.... unless you p...

Re: Drag knife.

Why drag it? A cheapo servo could rotate it. I agree, if I were striving for "perfection" a little bit of path look-ahead could indeed aim a knife in the intended direction of cut. It is quite possible that this is matured knowledge at some high end machines. I am being selfish, for MY wa...

Re: Drag knife.

Thanks, I had found the Rockcliff site before but didn't find (&still haven't found) the 0.25mm offset spec. That may well be close enough to zero that it approximates zero. Of course as it approaches zero the blade will "caster" less effectively. On the cost issue; I had hoped for som...

Re: Drag knife.

if you are worried about drag offsets with software, im sure you can manually drag the lines past the intersection of issue and do a seperate lead in/out for each line segment. doesnt seem like this guy is having any need or issues with. http://www.youtube.com/watch?v=YqvgA1P5hWg Yes, that can work...

Drag knife.

I want to cut some vinyl and want to NOT lazer burn it. I found a few threads in other places that deal with building (or buying) the drag knife itself, but so far I haven't found a general solution to the drag offset issue. Many suggestions say to just avoid radii less than some limit, or to over c...

Re: Smoothieboard group purchase

So, PART of the puzzle is to find and buy all the required plugs and pins, then crimp pins on, etc. OR to get the board without the sockets and SOLDER the wires directly. Soldering is easier (for ME) and more reliable - even when crimps are done right there are still the dry contacts. I think I'll g...

Re: Fly-n-Strude from Trick Laser

626Pilot, why would the extruders need to be on the arms, why not have them on the carriages. Putting them on the arms brings them closer to the hot end and lets me center the EZ-Struder output relative to the effector as well as I can. It goes out of center as the effector moves toward the edge, b...

Re: Smoothieboard group purchase

No update in the Google group for quite some time.
If enough people drop away from this maybe the ACTUAL volume will fall below the discount level, then MORE people will drop out and there will be a lot of surplus smoothie boards in excess inventory.
I *HOPE* not.

Re: Need help to design this.

Something to think about as you try to slice a PIPE is how you want infill - whether or not you want any. Almost any infill pattern between the inner and outer surfaces of this pipe will vary by position around the circle. It may matter, or it may not. In any case as an experiment, or as a learning ...

For the application outlined in the root post - would a truncated cone be more suitable ? Those are easy enough to draw in most drawing tools and if you want to get fancy you can sketch it as a half section and do a rotate extrude.
