Hi!
I have a weird problem with my CNC machine. When I move my machine with keyboard arrows, it will move very smoothly and nice to all directions. in all 3 at same time also.. Also if I CNC mill with direction of X or Y or Z with G-codes it works nice. but problem comes when it goes X+Y in same time. X+Z or Y+Z dosent cause problems. This causing very weird and terrible sound, and huge vibration. maybe something with microsteps.. i don't know.. I can post a video of the sound here, after I upload it in to youtube or some other place. The vibration makes my whole cnc machine frame shaking. Its bit hard to explain, maybe the video would help a lot more..
