@neverdie That has got to be one of the smoothest benchies I've seen.

@neverdie If you have an E3D V6, then you are running a J-Head.
Not sure exactly why they call it a J-Head as it looks nothing like a J shape...

I assume you just swapped out the heat block? The Volcanos are like a standard heat block only stood on end.

@neverdie Are you using an E3D J-Head with your Volcano hot end? I am in the process of working on an E3D clone J-Head setup with a Bowden extruder, but I went with the standard heat block and not the Volcano.

@simple Do you have a link to more information about this part?

@sundberg84 I have tasker on my phone. I will have to try this. I had some issues on one of my previous phones so I didn't use tasker as much as I thought I would. I woner if it will work better on my Samsung Galaxy S8+. It would also be nice if I could get geofencing working too.

@sundberg84 if what @Yveaux says is correct, wouldn't the phone constantly connect and disconnect and trigger tasker?

You can also use 3 AA batteries in a configuration like this:

I have noted values for rechargeable batteries as these have a nominal value of 1.2 volts vs 1.5 volts for an alkaline battery. The 4.5v side would be to power the PIR and the 3V side to power the pro mini.

@neverdie Can you run a stock GRBL build on RAMPS?

Expanding on that, I mapped it out further to give people an idea of how it's calculated.

And the scad based on my previous post.

 $fn = 6;
 fudge = 0.01;
 
 pi=3.1415926;
 large_diameter = 40;
 circumradius = large_diameter/2;
 inradius = circumradius/(2*tan(180/$fn))-1;
 
 height = 2;
 line_width = 1;
 
 for(i=[1:$fn]) {
    rotate([0, 0, (360/$fn*i)+30]) translate([inradius*2, 0, 0]) rotate([0, 0, 30]) honeycomb();
 }

 module honeycomb() {
     rotate([0, 0, 0]) hollow_cylinder(large_diameter-line_width, height, line_width);
     
     for(i=[1:$fn]) {
         rotate([0, 0, (360/$fn*i)+30]) translate([inradius, 0, 0]) rotate([0, 0, 30]) hollow_cylinder(circumradius, height, line_width);
     }
 }
 
 
 module hollow_cylinder(diameter=10, thickness=2, line_thickness=2) {
     difference() {
         cylinder(thickness, d=diameter);
         translate([0, 0, -fudge/2]) cylinder(thickness+fudge, d=diameter-(line_thickness*2));
     }
 }

@neverdie I created that basic pattern in OpenSCAD.

Here is the scad

 $fn = 6;
 fudge = 0.01;
 
 pi=3.1415926;
 large_diameter = 40;
 circumradius = large_diameter/2;
 inradius = circumradius/(2*tan(180/$fn))-1;
 
 height = 2;
 line_width = 1;

 rotate([0, 0, 0]) hollow_cylinder(large_diameter-line_width, height, line_width);
 
 for(i=[1:$fn]) {
     rotate([0, 0, (360/$fn*i)+30]) translate([inradius, 0, 0]) rotate([0, 0, 30]) hollow_cylinder(circumradius, height, line_width);
 }
 
 
 module hollow_cylinder(diameter=10, thickness=2, line_thickness=2) {
     difference() {
         cylinder(thickness, d=diameter);
         translate([0, 0, -fudge/2]) cylinder(thickness+fudge, d=diameter-(line_thickness*2));
     }
 }
