    Default Y axis end stops and prox switches

    Setting up a PRSAlpha 48X48. The YZ car slides all the way to the left and the car hits the side of the gantry. Obviously this is not correct. The factory was supposed to install the bolts and end stops, but it does not appear they are in the correct position.

    Can someone send me the correct positions?

    I have the bolts set so that it triggers the prox switch when the yz car is about 2 inches from the gantry and the end stops so the yz car stops 1 inch from the gantry.

    Is this an okay setup?

    First-time, so I have no experience. Thanks for the help!

    The bolts/targets are NOT factory calibrated. Move them manually so that they trigger just before the mechanical stop. Be careful not to poke the barrel of the sensor out too far or it'll get shaved off.

    To gain extra travel in the -Y direction, remove the bolt and nut closest to the gantry end plate, and slide it all the way back against the end plate. Tighten it up.
