Scrapper of metal
I’m on the verge of building one and wondered if anyone has one.
That’s # 6 on the to do list 4x4’ In size. I’m thinking the gantry would fold down as well as the table so it could be stored attached to the end of the bench to cut down on the diminishing floor space. I have the steppers, drivers, breakout board and ballscrews that I’m thinking about using. Any thoughts about ballscrews verses gear drive?
I built a 4x4 table based on the video's from MakingStuff off of youtube. If you to patron support him for access to the files, be aware they are not great. Holes in the wrong locations, wrong sizes etc. I'm using linuxcnc with a 7i96 hooked up to a Gecko G540 and a CNC4PC C10 board. G540 is motor control and limit, C10 is other IO including a mesanet THCAD-300 which is hooked into my Hypertherm 900 I bought at auction for $400 without torch. Machine torch was another $400 from PlasmaDynUSA on eBay. With the THCAD I have torch height control. Linuxcnc ha a nice plasma screen setup called QTPlasmaC. the options there are plentiful.
