I'm having an odd issue after updating my firmware from 1.0.2 to 1.1.0-RC8 compiled under Arduino 1.8.1. Upon updating the firmware the first communication attempt is interrupted:
The next attempt at connecting is always successful.
Even before connecting, both Z steppers and the X stepper make periodic clicking sounds every 1 second. The affected steppers make a clicking sound but don't appear to be moving. The extruder stepper and the X stepper are unaffected. When I try homing any axis, the stepper motor being commanded will start to home but will be interrupted by the periodic 1 second issue which interrupts the homing and causes the motor to stop and then start moving a tiny bit every second toward home.
I had no issues with my hardware and Marlin 1.0.2 so I'm curious if anyone else has run into this issue. I'm certain it's a firmware bug or configuration error because it was present on my previous RAMPS 1.4 setup which has been replaced with a RAMBo 1.3 board. I'm stumped :(
