The plans/hardware/electronics/mechanical includes everything but the wood structural components that can be cut by the customer. This plans/hardware option includes all of the electronics, like motors, drivers, controller, and all of the cables and wires to connect all of the electronics together. The mechanical components include shafts, couplings, linear rails, bearing blocks, sprockets, lead screws, etc. The hardware consists of all of the screws nuts, insert nuts, cross dowels, etc, to assemble all of the structural, mechanical, and electronics together.

The overall dimensions of the machine when mounted to a wall will be 119" from side to side and 25-1/2" inches out (from the wall to the longest part which is the bottom). Height of the machine (clearance) is about 76" maximum.

Actual table dimension: 4'x8' is 56.078"x 121.50" (the overhang in the illustrations should be 3/4" thick)
To determine the frame dimensions, first consider using the frame height shown of almost 3' (2.86'). The width of the frame should be 4" narrower than the dimension from rail edge to rail edge (6X rail to rail is 80.078"). This will provide a 2" overhang on both sides (4X frame width should be 56.078").
The length of the frame should be 4" shorter than the desired length of the rails to provide a 2" overhang on both ends. The travel length will be 20" shorter than the rail length due to the space occupied by the gantry sides.
Two long pieces of 3/4" material will need to be placed on top of the frame with the 2" overhang on the sides and the end. These long strips of material will receive the rails and the chain mounts on the ends.

Our hold down method is screws. For a 4'x8' 3/4" sheet, we use 6 screws around the perimeter of the sheet. This provides sufficient hold down for milling. For the vertically oriented machine, the sheet also rests on a small ledge, making it easy for the board to maintain position while fastening.

Can the vertical CNC router do about what a horizontal router can, like cutting out 3/4" cabinet doors from a 4'X8' formica clad sheet? If so, how do you hold it - with Vacuum? Is a vacuum system available?

Do you use the same bit?? If so, check if it is not dull or worn. Maybe it is time for a new bit. Additionally, I would check if the z axis mounts are tightened correctly and the router has no wiggle room. If that doesn't help, check all of the play that may be in the structure and where the bearings run along the rails and tighten all loose connections that may be present.

Additional Information:
So confused....is backlash and chatter the same thing or are they completely unrelated?

Additional Information:
Chatter and backlash are different. Backlash is a condition where there is play in the mechanical parts (i.e. a nut not tight against the treads, or two gears not meshing together tightly). Chatter is a phenomenon caused by many possible conditions including vibration, resonance, springiness and flexibility in the system and certain types of end kill and machine movement scenarios.

Additional Information:
Meant to say end “mill” at the end there.

Yes, the 2'x4' CNC router (blackToe) cuts within the full 2'x4' dimensions and a tiny bit more.

In the customer service live, just enter "motor tuning" and it will give you a list of all the recommended or default settings for our machines. However the acceleration and velocity for the greenBull(other machines) will be an actual determination on your trials. You will want the highest possible acceleration and velocity without the motors stalling, so you can do increments of ten to be on the safe side, if it is too slow try increments of 25.

The steps per inch is dependent on the microstepping:
Steps/Inch for the x and y
Steps = 200 motor steps per revolution x 16 microsteps = 3200 steps
Inches = sprocket number of teeth x pitch of the sprocket = 14 x .25" = 3.5 inches
steps/inch = 3200 / 3.5 = 914.28
This is really a starting point. You will then need to use the mach3 calibration function to get the perfect steps/inch value. Use as long a measurement as possible when calibrating.

Velocity:
Start with a value of 1000 ipm. Increase this value with a relatively low acceleration at about 10. You will notice at a particular velocity that it will stall. This is your stall velocity. I would take the stall velocity and reduce it by about 30% to 50% which should give you a good final safe velocity.

Acceleration:
Once the velocity is found, raise the acceleration until it start to stall at a low velocity. Reduce the acceleration by about the same percentage to stick with a safe acceleration.

The acceleration is mostly dependent on torque (current) and the top speed is dependent on the amount of voltage.

Give some tests with all of the axes running at the same time. If you notice and stalling, reduce velocities and acceleration depending on when the stall happens (top end, or acceleration curve).

While motor tuning what are the recommended steps per inch, velocity, and acceleration for the GreenBull CNC?

This is an open ended question to which there could be many possible answers.

The requirement of a laser cutter is having a laser with enough energy output to cut the intended material. Generally, the laser function is not tied to the working area unless the laser tube is stationary, where the farther the beam has to travel, the less energy results at the intended area (on the surface of the material).

We don't use servo motors here. Rather, we use precision stepping motors instead.
