I am running into an issue with my build. My ox for some reason my X axis the stepper motor on the left moves a half of second before the right side. It is going to make everything off centered. I have the 4x smoothieboard and have it jumped so each get there own stepper driver.
Hi JD. If we understand correctly your saying there is a 1/2sec delay between the two Y motors (front to back)? You are using a smoothie with 4th axis slaved to the other Y? Are you sure that the delayed Y motor is driving? One Y motor will drive the entire Y gantry system but will cause the non-driven side to appear to have a delay. This is kind of a cantilever effect.
You know what makes a lot of noise? When you haven't swapped one of the y motors wiring or in the software. On motor is going one way and the other wants to go the other way. lol Ask me how I know. I am using tinyg though. I think the command was g1 m or something like that to get the tinyg to drop the motor script.
