This project documents the repurposing of a rescued 1980s IBM 7575 SCARA Robot Arm, into a functional 3D ABS printer. The project features some motor upgrades. A robot is a machineespecially one programmable by a computer capable of carrying out a complex series of actions automatically. Robots can be guided by an. Epson RS4 SCARA Robots 550mm. Industry Leading Work Envelope Usage No Lost Space in Center of Work Envelope Extremely high speed with superior cycle throughput. The huge reach of the 7. Some of these prints are shown below. Video. of Operation Vid. Starting. at the end. The following is. IBM 7. 57. 5 robot arm abs printer tackling some. Note this is running from the developed hardware detailed. This is a quick guide to help with assembling the Arduino CNC Shield V3. XX. We also have a discussion forum for this board httpforum. Shameless Plug In the UK and like Arduino stuff check out our newly opened web store oomlout. A quick video of a completed Arduino controlled servo robot. All hardware to computer. DB2. 5 parallel port. Check out the video in HD  Link. Breathing Life. into the Beast. The. robotic arm this project is built around was scavenged from a lab. Unfortunately, the motor drives, servo. The arm initially ran. DC Servo motors with high precision encoders. Each motor would. PID feedback controller to allow for precision. The DC motor provided the high torque low RPM drive, and. Presently. a number of 3d printers. DIY front, rely on feedback less stepper. Using high power steppers, sized much greater than. For this. project i opted for a mix of the two. Phd Thesis On Hepatoprotective Activity Of Plants there. A. large wooden workspace was built to support the 1. The control. electronics grew in complexity and sprawled across the right side of. Shown is 2 DC power supplies to supply the 1. Datasheet linkTo get this working i took the iterative approach, started with basic. Heated. Build Platform. The. heated build platform consists of a 18th aluminum plate, donated by. W power resistors. Teflon coated wire rated for. C was used for wiring the resistors in series. The heated build. A supply, tuned to 2. V. The heater. assembly dissipates roughly 2. Two linear temperature measurement probes, each using a separate. Microchip MCP9. 70. TemperatureHeater controller. After. a 6 minute warm up time, the build platform reaches 6. Celsius, near the stress relaxation point of the. ABS plastic used in the printer. Its also, fortunately, right below the argh, i singed my hand. Pile. of Switches and some Dials. I. used a number of 2 position slider switches for the various settings on. ABSPLA  This. is fed as a logic 10 to the thermal controller, and sets it to use. ABS extrusion temperature or the PLA extrusion temperature. FANFAN X2 This. FAN motor controller and selects either 1. The. Display, shown far right is the power interface, displaying each. System. Layout. Configuration My. To do this, i made use of Linux cncs great tye in with. The system topology can be broken. Theta 0, the base DC brush. Theta 1, the second motor on. Z axis, stepper driven without. Extruder motor, driven from an. H bridge, capable of extruding and quick reversing to prevent. Each. motor drive is broken into 2 signals, Step and Direction. A Step. is effectively counted as a rising edge on the step line and informs. Before. making any movements, the direction bit is read, if its a logic 0. The physical step and direction lines are generally tied to. These pins are called from Linux cnc, and. MOTOR CONTROLSHow Image. Media. For the main axis, a giant DC. Opting for replacement with a stepper. To drive this motor i. H Bridge that could use encoder data to. To drive a DC Brushed motor with encoder in a. PID loop, taking. Whats PIDyou say Continue. Proportional. Integral Derivative. PID. is a feedback control toplogy for closed loop control of a system. Open. loop control is simple, imagine you want to control a DC brush motor. To do this, you could pulse the. Unfortunatley, loading, wear, and other factors make. Closed loop control takes that goal of. The feedback mechanism could be as. The values for P, I. D effect the systems response to changes. PID consists of 3. Proportional outputs value proportional to the current error. Integral accumulated offset, and Derivative rate of change. The theta. 0V2 controller preforms a high speed PID loop taking. An example of the over undershoot with different constants is. Determining. Max Operating Trajectory Speed. Next. I needed to see the bandwidth of the PID loop. A GPIO tied to an led. From the oscilloscope right, we can. PID loop is roughly 2. Hz. As. the Step input is tied to an edge triggered interrupt, the 2. Hz is. the maximum rate the hardware can respond to the encoder inputs during. Far right is a view of the encoder inputs green. Extruder. Upgrading. Hot End of the printer. Initially. i had been using the 2x resistor block heater extruder head. The. root of the resistor semi frequent meltdown came down to component. That resistor was rated at 1. W. when operated at 2. C, at. 1. 60. C, it was rated to 2 watts. I was pushing 1. W into the resistor at. C, and after a few hours, the part failed. A number of other. Link. A. NTC thermistor is kapton taped to the heater block and fed through. I plotted some comparisons. Cartridge. Heater Teflon wire and  milled tapped new. The heater Link is held in place with a. The wire feeding power to the cartridge heater is. Teflonfiberglass coated and heat resistant. Putting. The extrusion. This is re connected to the DC. I kapton taped the thermistor to the aluminum. Ventilation. Ventilation. System I built a fume. DC blower fan. The. It adds a nice industrial feel to the setup. Red. arrows shown right indicate the direction of airflow. Canon Ef 70-200 Repair Manual. The shorter. black tubing link connected the extrusion head. The DC blower Link. Quiet was. a relative term, and i ended up de rating the operating voltage to 9v. For those out there whod like to use. A, at 1. 2v it pulls 3. A. I. first ran across these type of in line fans from a friend, Shane, on his, um, alternative. LinkSome. quick proof of functionality. Why use such a. large ducted fan Because of the extended. It is way easier to throttle. Noise. I ran the DC brush motor from one side of a. Hz. As the Exhaust fan only needed. H Bridge for the. The. Acoustic noise wasnt the most of my concerns, as the motor was located. As it. turned out, switching 3. A at 3. 0k. Hz on a long wire made a wonderful. EMI. Enough EMI to cause the Theta 0 encoders to miss steps on occasion. I. rectified the problem by adding a very advanced RF choke, shown far. LINUX CNCHow. HAL files, running the show. In Linux CNC, 2 files do all. The INI file describes each axiss type, maximum and. HAL file describes the. Linux cnc and the external hardware. The Linux cnc package has some excellent, dense documentation on both. INI  link and HAL link files. Shown right is  the user interface,  consisting of a.
