Actually, any "relative" origin point can be used for moving a long piece through a CNC. I use some of the dozens of pin locations on my CNC bed and dowel pins to do just that. On long pieces I machine dowel holes on the back so I can move a piece along the bed.
After spending many hours thinking about the best position of your router you will discover that any cnc machine (no matter what is the manufacturer) has the home position in front of the wall, opposite at the place where your seat is.
I have no argument with what's said at 2:30; however, ipso facto, when you say origin point and then move a piece within the CNC framework, it should be said that the nominated origin point moves when the workpiece is moved. Otherwise, in the context you gave, it becomes easy to get confused by your use of words - to me, at least. That is, the home position varies with the nominated position on the spoil board. I should also add that since the presentation is 5 years old, it might have aged itself.
Some questions.... Are limit switch also a homing switch too? Since arduino cnc shield don't have pins for homing it has only limit switch pins and if it's separate switch, how many it needed or just homing switch installed on z axises and it also installed both sides? Like z+ z-?
Generally, homing and limit switches are the same thing. What they do is give the machine a reset to 0/0. From there, movement can be measured out accurately. Your question is kind of mixing the two concepts together: the concept of homing with your particular physical hardware. CNCs are often very different from each other when it comes to hardware and design. You're going to have to ask your hardware manufacturer about your hardware configuration. The video is about an important concept: the strict correlation of machine hardware positioning, part position, the CAD drawing that everything is based on, and of course, CAM instructions. This is critical stuff for anyone using a CNC.
@@digitalwoodworking i built my cnc machine using arduino but unable to control or run because of some configuration complications involved I am new in it I wanna start something simple as 2d latter ( on 3d wood sheet ) cutting or engraving using Inkscape soft if possible. Or copy past someone else g code just like with arduino code so I can learn from it.
You're at a point you really want to get some help getting your machine setup and some one-on-one or classroom instruction would be a good idea. Expecting to just learn this off the internet could get lead to serious problems. For example, you never want to use someone else's Gcode. That would be a serious mistake. @@omsingharjit
@@digitalwoodworking why can't we use someone else g code I wondering what could go wrong? Assuming g code dimensions is smaller than my machine limits.
Hi Tim, Do any of these Flatbed CNC routers make provision for a 4th axis (running right up the center of the bed along the X-axis and under the gantry) for turning 3-D objects (not necessarily round) between the centers?
Several commercially made machines do either allow or include a 4th axis. Look to the Laguna IQ or Axiom Precision or the Legacy Maverick CNCs for these kind of options.
3:41, thats a great idea. Could that point also be used for tiling? Always moving your stock to that pinned position?

If you don't know why sharing Gcode is an actual bad thing, I'm sorry but I can't help you. Best of luck on your journey. @@omsingharjit
