Meditech: Control panel PCB and circuit installation

balearicdynamics

PCB prototyping

After a final check the schematic is expected following the previous tests done with wires and breadboards so the final PCB prototype has been milled as shown in the images below.

As shown in the final circuit assembled image, only the control components as soldered on the board (mainly the various pull-up resistors). As the board should be fit in the Meditech box and connected to the elements installed at different distances, all the other components are wires with connectors.

Installation

The following images shows how the board and the connections are set inside the box. The control components (LCD, LED status, IR Sensore and calibration potentiometer) are on the top side of the lid, accessible during the normal usage as it should remain closed (and possibly locked). The only two parts that remain inside of the box are the temperature sensor put in the RPImaster ares (the Raspberry-PI 2 main unit) and the can connection that is controled by the board. A couple of flat cables connect this control panel interface board to the ChipKit PI and another flat cable connects the board to the Raspberry PI GPIO for the IR sensor.

Final view

The following images shows the final view of the control panel installed on the top side of the lid. The areas - actually empty - on both sides of the lid surface will include the plugs to connect the diagnostic probes, actually under construction.

    Thanks ! It's a compliment, I suppose (?) image

    Would that be like the axe my grandfather gave me ..

    I've replaced the handle a couple of times, and the head broke so thats been rerplaced as well...

    but its the same axe.  image

    Uff... It's the third time I try to send you the following image (a global view) and a short video of the mill machine while working. Try again ...

    Started from a decent structure then all the rest was replaced. Motor controls, motors, spindle, added the silent box, added a vacuum for dust and in some cases to mage a vacuum plane, changed the motor controller, addded a PC with parallel interface and other tools dedicated... Mmmhhhh changed the shaft, added some decent software for 3D and 2.5D CAD (Artcam, SolidWorks + SolidCam), worked a lot on Eagle to find the righe toold for direct G-Code conversion, made a custom controller and wirings, interfaced all to the Mach3 after trying EMC2 then now I can do almost any work I need for prototyping.

    Ah, last added a USB microscope to control the process while milling.
