Re: X and Y probing with G38.x

Thanks! I re-set the clip and puck, and re-tried what I had been trying before - just entering commands like "G38.2 X-10 F1" and I could only get the machine to probe in one direction for X or Y regardless of the sign (positive/negative) of the modifier for X or Y. I entered "G91" then ran the G38.2...

Re: X and Y probing with G38.x

Will: yes, I'm using a continuity probe/puck - an alligator clip to the end mill (or in this case a piece of 1/4" rod in the collet) and a conductive puck. I just placed the puck in contact with the round metal object, then checked for continuity with a multimeter to make sure the round object was a...

X and Y probing with G38.x

I've had no problems with Z "down" probing with G38.2 to set tool height. (I'm still on v0.9i) I needed to probe the inside diameter of a conductive circle to center on it, so I attached my puck to the object, and the clip to a round bar in the "spindle". I was able to run G38.2 X1 F1 and G38.2 Y1 F...

Re: VFD Speed Control

I've been poking around into the unfamiliar world of 3 phase spindles and VFDs, so I came across this thread and was curious if this worked well? Also, would it be nuts to take GRBL's 0 to 5v output, feed it to the input of another arduino and use a RS485 Shield https://www.sparkfun.com/products/129...

Re: Stiffness of the spindle carriage plate

Personally "three plus one" axis would be nice for me - standard 3 axis operation with the workpiece mounted on a 4th axis, which only rotates between complete "3 axis" operations. This could be implemented with GRBL or similar continuing to operate the normal 3 axis, and the control software on the...

With conductive clips, can bCNC currently find the center of the circular hole in that edge finding product?

Re: Making an SO3 start in the same spot, every time..

I think that Carbide3d is taking an approach to their software that tries to keep things very simple so they would be unlikely to add on "features" like compatibility with that specific edge finder product. (Or to a degree, any touch plate or edge finder other than how they have things set up with t...

I also wonder.

But it being the result of 2 punches makes more sense than that Carbide3d provided CAD for a slot, and someone somehow in setting up the laser transformed that into two overlapping circles for the laser path.

Re: Finishing Techniques

If you're interested in some in-depth information, I highly recommend "Understanding Wood Finishing" by Bob Flexner. The book covers a wide range of finish types and techniques in depth. Crucially, a lot of manufacturers of finishes don't state what's in the can. Flexner has done a lot of research i...

Re: Expansion packs announced

If I were them I would not sell the extrusion by itself. There is just more money is selling you a complete bundle. Edward made a design/engineering decision pretty early on with this generation that the extrusions and the steel frame would be pretty much inseparable. This addressed some stiffness ...
