![]() ![]() Begin by mounting the arduino along with the CNC shield onto the base of the electronics module. The electronics module consists of three primary parts: the lcd display, the Arduino + CNC Shield, and the power port. Next we build the heart of the system, the electronics module. You can use an additional clip or clamp to prevent the belt from loosening over time. Lastly, pass the belt around the two pulleys and push the ends through the belt holder pieces on each side of the gantry. Once again the fit is snug and will not require any additional reinforcements. Finish the assembly of the pan and tilt mechanism by pushing the pan bracket onto the pan stepper motor that is attached to the gantry. The fit is snug and does not require any extra reinforcement.įinally, mount the pan motor to the gantry by sliding it in from one side and secure it using the bolts that were provided. Mount the tilt stepper motor to the pan bracket using the given mounting bolt and slide the shaft into the hole on the tilt bracket. Use an additional nut or washer between the two brackets to create a slight gap between the two. The parts and pieces required for this are:īegin by embedding a bearing into the hole on the pan bracket and attach the tilt bracket piece to the pan bracket using a nut and bolt passing through the hole on the tilt bracket and the bearing on the pan bracket. Once the slider mechanism is built, you can begin to assemble the pan and tilt mechanism. Test the fit of the gantry on the rail and make sure it rolls smoothly. Use 4 nuts and bolts to attach the four bearings along with the pan stepper holder. The other 4 bearings are mounted using the slots on the gantry piece so that you can adjust the position of the bearings such that the gantry rolls smoothly along the rail. The 2 bearings for the top surface are connected along with the belt holders to the gantry piece using a single 4 mm nut and bolt for each side. The gantry uses 2 bearings that roll along the top surface of the rail and 4 bearings (2 on each side surface of the rail) that prevent skewing. Next, you can start assembling the gantry. These holes will allow you to mount the slider onto a tripod. The holes should be made at the middle of the rail, 6 cm apart, and 0.5 cm from the bottom face of the square tubing. Once the tube is cut to length, drill two 4 mm holes on the rail. I used a 60 cm length of tubing, but this step depends on your needs. Note:The parts are included in one of the following steps.īegin the assembly by cutting your square tubing to length. ![]() This is one major point that traditional sliders tend to lack.įinally, I designed an enclosure that would hold all the electronic components and a display that will display useful information. This would allow the user to easily assemble and disassemble the slider and carry it around with them. This allowed the gantry to roll smoothly without skewing.Īnother goal while designing the automated slider mechanisms and parts was to keep the models as compact as possible and implement a modular design. The gantry or the slider used regular bearings as wheels that kept contact with three faces of the square tubing. The design was made with structural stability and ease of assembly in mind. Next, I modeled the rail and made the two pieces that held the stepper motor and idle pulley on the ends of the rail. I began by importing the stepper motors into the design and built the pan and tilt mechanism around them. The automatic camera slider was designed in Autodesk's free-to-use Fusion 360 3d modeling software. ![]()
