prusaprinters

<p>Super cheap and completely printable mini CNC.</p> <p>I had a few Parts left from an old 3D Printer which i wanted to use for a tiny CNC which i can use to mill (engrave) PCB´s and smaller parts for my micro RC Trucks.</p> <p>For the Ramps I´m using a modified version of the RS-CNC Marlin code (i will upload it during the week) I connected the Spindle motor to the FAN output and modified my Start and End gcode with M106 (on) at the beginning and M107 (off) at the end.</p> <p>I will also Upload a few more videos and files.</p> <p>First Testrun with thin Plywood: <a href="https://youtu.be/KufswjqJp_4">https://youtu.be/KufswjqJp_4</a></p> <p>If you wanna suport me, please buy with the Links i added. These are Affilate links, so it won´t cost you more but generates Points for me that i can start other cool pojects. Thanks :-)</p> <p>BOM:<br/> 3x Nema 17 Stepper <a href="https://www.banggood.com/custlink/333h9SGlvN">https://www.banggood.com/custlink/333h9SGlvN</a><br/> 2x 8mm Smooth Rods 22cm <a href="https://www.banggood.com/custlink/m3GyISGlcv">https://www.banggood.com/custlink/m3GyISGlcv</a><br/> 2x 8mm Smooth Rods 18,5cm <a href="https://www.banggood.com/custlink/m3GyISGlcv">https://www.banggood.com/custlink/m3GyISGlcv</a><br/> 2x 8mm Smooth Rods 15cm <a href="https://www.banggood.com/custlink/m3GyISGlcv">https://www.banggood.com/custlink/m3GyISGlcv</a><br/> 12x LM8UU Bearings <a href="https://www.banggood.com/custlink/m33YZiGLht">https://www.banggood.com/custlink/m33YZiGLht</a><br/> 2x 605ZZ Bearing <a href="https://www.banggood.com/custlink/KGmdiIvlhq">https://www.banggood.com/custlink/KGmdiIvlhq</a><br/> 3x Lead (22cm, 18,5cm and 15cm) <a href="https://www.banggood.com/custlink/GvKhZ9GOdo">https://www.banggood.com/custlink/GvKhZ9GOdo</a><br/> 3x Coupler Lead to Nema <a href="https://www.banggood.com/custlink/vGGh8iDjYN">https://www.banggood.com/custlink/vGGh8iDjYN</a><br/> 4x M3 Spacer 20mm <a href="https://www.banggood.com/custlink/KmmdI9vLJT">https://www.banggood.com/custlink/KmmdI9vLJT</a><br/> 4x M3 Spacer 15mm <a href="https://www.banggood.com/custlink/KmmdI9vLJT">https://www.banggood.com/custlink/KmmdI9vLJT</a><br/> 4x M3x25mm Screw<br/> Arduino 3D Printer controller (i use an Arduino Mega with RAMPS 1.4) <a href="https://www.banggood.com/custlink/3mvhS8Gjv1">https://www.banggood.com/custlink/3mvhS8Gjv1</a><br/> Display (Optional) <a href="https://www.banggood.com/custlink/GvKdi9KjK2">https://www.banggood.com/custlink/GvKdi9KjK2</a><br/> 12V Powersupply <a href="https://www.banggood.com/custlink/GDvyZSDapt">https://www.banggood.com/custlink/GDvyZSDapt</a><br/> 3x Endstops <a href="https://www.banggood.com/custlink/3DGR8ZDoRy">https://www.banggood.com/custlink/3DGR8ZDoRy</a><br/> 2x Fans <a href="https://www.banggood.com/custlink/DKmhISKLCg">https://www.banggood.com/custlink/DKmhISKLCg</a><br/> 2x Aluminium Stripes<br/> Spindle Motor <a href="https://www.banggood.com/custlink/KmvEiI3Omd">https://www.banggood.com/custlink/KmvEiI3Omd</a></p> <h3>Print instructions</h3><p>I Printed everything with 70% infill.
