I have committed myself to taking a fresh start and doing some more CNC work. The reason being is I have discovered some projects I want to do that will provide new products for The Hobbyist Machine Store. They will be best produced through CNC repeatability. The store has proven to me that I must produce my own product. Exclusivity is the key to success. My products may be similar to others but will never be the same.
I am doing some minor rebuild on the original homebuilt CNC gantry style engraver shown here, primarily a solid mount for the Dremel tool I already own. I am also considering making a mount for the Proxxon Professional Rotary Tool IB/E (NO 38 481). The working area of the engraver machine is 5.5″ x 6.0″ so the small hand engravers are a good match. My first projects will fit this small machine very well.
I have also ordered the basic parts for a second CNC power supply / controller. It will be set up to operate this little gantry machine. I will post that project in the THMS web site. I will use the same components as my first controller but in a different case and layout. I don’t like to mess too much with success.
Then, a new design is to build a larger gantry CNC machine that will be able to use more powerful spindle drives such as high speed routers. Table working area will be at least 12″ x 24″ and may approach the 24″ x 36″ range as anything bigger than this gets out of the reliable range for stepper drives. Extremely fast rapids are not required and I don’t want the expense of designing a servo system. Anticipated first project (product) is much smaller than the larger… Continue reading
