cnc-laser-engraver-instructables Motors are specified with DC flowing through their coils. Attached the stepper motor onto the place using the screws and afterwards instructanles the smooth rods instruxtables guiding part into the holes given by keeping in mind that slider is moving freely not too hard. You must do one more thing, edit cnc laser engraver instructables Gcode file in notepad, swap out all of the Z commands with L Laser commands.

You're safe. Motors are specified with DC flowing through their coils. But what we are concerned with is maximum current. The voltage spec of the motor doesn't really matter, using the EasyDriver. Or any chopper driver, for that matter. Then it will cut the power to the coil until the current dips down again, then re-apply power, over and over again, about 20, times per second.

Feel free to look, comment or contact… More About StuartB44 ». Most of the parts I already had laying around in my shed. I removed the ribbon cables from the motors and soldered my own wires on. I found out why and fixed it.

The plug on the motor should face upward refer to image. Attach the timing pulley to the stepper motor and the bearings to the acrylic frame. Use the machine screws and nuts to bolt the bearings and washers to the acrylic plate.

Each plate will have 4 bearings attached to it. Attach the laser diode to the acrylic sheet using the included screws.

Peel away the label on the laser to access the threaded screw holes. Attach the stepper motor to the acrylic sheet. The white JST plug on the servo motor should face upward. Join the 2 acrylic sheets together with the machine screws and nuts.

There will be a roller bearing and 2 nylon washers on every screw. In this step, we will put together all the individual components that we assembled in the previous steps into one complete machine. Lay the timing belt across the last piece of aluminum extrusion and secure one end of the belt with a T-nut and set screw. Pull firmly to take the slack out of the belt and then secure the other end to the extrusion with T-nut and set screw.

Attach an Y-axis stepper motor to each end of the aluminum extrusion using the included machines screws. The bearings and motor pulleys will face inward. Route the left Y-axis stepper motor cable through the center of the X-axis extrusion and plug it into second JST port. Use the spiral loom to wrap the wires to prevent loose wires from snagging while the carriage moves. Ensure there is enough slack in the cable by first moving the carriage to the farthest point from the control board.

This should be the top left-hand corner. Attach an acrylic leg to each corner of the base frame. The assembly of the laser engraver is now complete! Download and unzip Benbox 3. Download and install the Arduino IDE. Click install.

When the firmware has installed successfully, you will see a green checkmark beside the update firmware title at the top. Before making your first print, make sure you put on the laser protection glasses that are included in the kit!

We will focus the laser and align it in this step. Align the laser by clicking the motor control button and move the laser until you have it oriented in the position you want. This starting spot will correlate to the red arc at the 0,0 position refer to image. Draw an simple image using the drawing tools on the left. To delete any part of your drawing, right click on the part. Press the green start button to start the print. To stop the print at any moment, click on the red stop button.

Funny i tried to find this on the site mentioned but all i can find is the same description of putting this thing together complete with the same link. By leeselectronic Lee's Electronic Follow.
