Not to beat up on Qidi because I love the printer and run it every day, but I have had another issue. Grinding stuttering in the X-axis. Curious that if I reboot the machine it will quietly go through its startup routine, testing the limits and homing, until the printhead reaches the front of the y-axis (no limit switch in that direction) then the grinding starts. Once that starts it doesn't matter where the printhead is, it keeps grinding and stuttering. Reboot and repeat. I am thinking perhaps the x-axis stepper cable is bad so I ordered up 4 from Amazon yesterday, coming today. I guess we'll see...
