My first inspiration came from Bruce Shapiro&#8217;s eggbot. I tried a few variations of it and even the board from evil mad scientist.<\/p>\n<p>One day my friend Joe told me he was interested in CNC. I told him I had played with it for years but never seriously committed to it. We decided to build one at work over lunch.  Doing a little bit each week. We only have one day a week we can get together<\/p>\n<p>It is so close but only using 3 or 4  hours a week has been a little limiting. We got the x and y done and some  tuning so it can now plot pictures using a sharpie. We just have to finish  the z axis<\/p>\n<p>I recently completed a similar  machine at home using some old printer parts and a dremel.<\/p>\n<p>The base is a side panel from a computer UPS. A dot matrix printer gave it life to become the main carriage and the rails from an antique laserdisc player completes the z axis<\/p>\n<p><a href=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-225219-1.jpg\"><img decoding=\"async\" src=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-225219-1.jpg\" alt=\"20140117-225219.jpg\" class=\"alignnone size-full\" \/><\/a><\/p>\n<p><a href=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-225240-1.jpg\"><img decoding=\"async\" src=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-225240-1.jpg\" alt=\"20140117-225240.jpg\" class=\"alignnone size-full\" \/><\/a><\/p>\n<p><a href=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-225257-1.jpg\"><img decoding=\"async\" src=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-225257-1.jpg\" alt=\"20140117-225257.jpg\" class=\"alignnone size-full\" \/><\/a><\/p>\n<p>It&#8217;s driven by an arduino mini running GRBL 0.8c.<\/p>\n<p>There are 4 PIC 12c508 support chips. 3 handle the step direction deciding for the three axis and the 4th converts the z axis set and directions signals the a relay closure to operate a diode laser for simple engraving tasks.<\/p>\n<p>I used 6 toshiba h bridge chips to drive the bipolar steppers. There are 2 solid state relays one for the dremel and the other is for a shop vac. An old compaq notebook supply runs everything.<\/p>\n<p>Spindle codes control the dremel and flood coolant commands control the shop vac<\/p>\n<p>The first few pieces came out pretty good<\/p>\n<p>I used a dial indicator in place of the dremel  initially to level the table. I managed the get it to within .008 in. It&#8217;s not really crooked but cupped slightly in the center<\/p>\n<p>So far that hasn&#8217;t been a problem<\/p>\n<p>Here are the first tries&#8230;.<\/p>\n<p><a href=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-230213-1.jpg\"><img decoding=\"async\" src=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-230213-1.jpg\" alt=\"20140117-230213.jpg\" class=\"alignnone size-full\" \/><\/a><\/p>\n<p><a href=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-230228-1.jpg\"><img decoding=\"async\" src=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-230228-1.jpg\" alt=\"20140117-230228.jpg\" class=\"alignnone size-full\" \/><\/a><\/p>\n<p><a href=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-230245-1.jpg\"><img decoding=\"async\" src=\"https:\/\/www.kornequipped.com\/blog\/wp-content\/uploads\/2014\/01\/20140117-230245-1.jpg\" alt=\"20140117-230245.jpg\" class=\"alignnone size-full\" \/><\/a><\/p>\n<p>I was pretty happy with the results.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I started building CNC machines long ago.
