A technician has just taken their first set of readings on an alignment job. The solution calls for the removal of 0.100 inch from the back feet of the motor. There are no shims under the motor back feet. The technician reverses the laser head and prism to see if the alignment can be accomplished by moving the driven equipment. Again, the solution calls for the removal of 0.100 inch from the back feet, and there are no shims under the back feet of the driven equipment. What is the diagnosis?
