I am trying to do a test carve. The last time I tried eveything moved ok on the x, y, z when I tested it pre-carve. The test carve didnt work as I found out later the belt on the gantry was too loose. The gantry moved quite a lot during the carve (the left side would go up on the Y, while the right side would go down on the Y) and I broke a bit.
So I tightened the belts. Pre-test cut I still have the same issue when testing the movement - The left side of the gantry will tweak up on the Y, while the right side goes down on the Y. I have rewired the controller in case anything was loose but it doesnt make a difference.
Any thoughts was be greatly appreciated
