Arduino powered DIY radial arm sliding saw for thick metal plate pt. 1

Showing off my homemade automated radial arm sliding saw for cutting sheet metal or thick metal plate. For the moment this is a work in progress. This video was taken using the normal abrasive disk. Which works perfectly until i reach 3/8" into the plate, and then metal gets embedded on the sides of the wheel and causes it too grab and pull and bounce and isn't functional without constant wheel dressing, or new wheel replacement. So dry cutting is limited to 3/8" steel

Part 2 will show the upgraded diamond cutting wheel, enclosed wheel shroud with coolant and return system. stay tuned
