The "driver not enabled" message means exactly what it says. You will get it if you attempt a tuning move without either doing a standard move first (which will need to be done in open loop mode, since closed loop tuning hasn't been completed) or using M17 and the appropriate axis letter to enable the driver. We suggest you home the machine in open loop mode, then move the carriage away from the endstops so that the tuning move can be done without risk of hitting a motion limit.
"measured motion was inconsistent" means that when the firmware tried to move the motor a small amount at a time, it didn't move consistently. This typically means that there is too much friction in the system for the motor current to overcome. You can try increasing the motor current to the maximum that the motor can take just before the tuning move, and reduce it again when the tuning move has been done.
