Ok. So I dismantled my X and Y v-con rail system to add a bunch more v-con clamps. After I put everything back together, I began the squaring and tramming process as outlined in the CNC Router Parts video.
After drilling the 4 holes one of my measurements is off about 1/16". The video says to adjust the home sensors to square up X and Y, but it does not mention which sensor or which direction to adjust the sensor.
Can someone please clear up which sensor needs adjustment based on the measurements I have based on the inserted image?
