K40 Mini Custom Control Panel for Cohesion3D/RepRapDiscount LCD and Ammeter/Current Meter

prusaprinters

This is still a work in progress! I haven't gotten a chance to actually cut this (waiting on parts/time) yet. Putting it out there anyway. This is a Control Panel for the K40 Mini (the 30w, smaller version) that incorporates a CH3D/RepRapDiscount GLCD Controller, Ammeter, 10 Turn Potentiometer (For laser power control), On-Off-(On) Switch (for test pulse/continuous laser fire), and a Laser PSU on/off switch. Your parts might slightly differ from the ones used on mine, so double check and adjust measurements as needed, I've included the LightBurn project file, which includes layers for the front and back profiles of my specific components for spacing purposes. Some of the mounting footprints are taken from TechBravo's control panel (remix source), with the rest added/measured by me. Parts Used My specific iteration of the laser is the following: "OMTech 12"x 8" 40W CO2 Laser Engraver Cutter Engraving Machine Red Dot Guidance" https://www.ebay.com/itm/254782727987 (Note that this is actually a 30W machine, and commonly known as the "K40 Mini") Any non-stock parts that were used are: 10 Turn Potentiometer (Must be 10k Ohm): https://cohesion3d.com/shop/peripherals/replacement-multi-turn-potentiometer/ CH3D/RepRapDiscount GLCD Controller (The CH3D Requires an adapter that you canonly get bundled with the GLCD on their store ( :/ ) , but otherwise its a standard RRD GLCD): https://cohesion3d.com/shop/peripherals/graphic-lcd-control-panel-with-adapter/ 30mA Panel Mount Ammeter/Current Meter: https://cohesion3d.com/shop/peripherals/30ma-current-meter/ NTE Electronics 54-304E ON-OFF-(ON) SPDT 5A Switch (Used for Laser test fire control) : https://www.digikey.com/en/products/detail/nte-electronics-inc/54-304E/11649538 The above parts don'tnecessarily need to be sourced from above, but the CH3D store tends to be overall price competitive with amazon at the time of writing (+- $1-2) past the GLCD (which while I ammildly annoyed at the price for the proprietary LCD adapter, CH3D is run by a single guy who's incredibly responsive, writesfantastic documentation, and is overall very nice, so its not that big a deal in the end).
