Homing and Precision Homing with ClearPath Integrated Servos

Watch this TekTips video to learn more about homing and the different homing features included in the ClearPath servo motors. Upon startup, machines typically don't know where each axis is positioned. Homing is the process of moving an axis to a known physical position which all future moves will be in reference to. This video also demonstrates ClearPath's built-in homing features which can be configured in the free ClearPath software and require no additional programming.

I already use the hard stop homing on my lathe and it works quite well. But this will definitely be a plus, I'll upgrade today. Thank you for supporting your products in the long run. The autonomous homing procedure is useful for DIY CNC because if makes for a much more accurate homing that inductive or mechanical sensors, and does not waste the feedback line (have to use it as fault feedback) or any CNC controller input.

Awesome, love new content! Really hoping you are making more videos because it goes a long way to showing what is possible!

Very cool. I'm designing a simple piece of equipment that requires speed control, a start button, a home button and an e-stop.
I was considering using the ClearCore and incorporating limit switches... but I don't think I need that anymore.
1 pwm speed control and 2 buttons I should be able to setup with just the I-O on the integrated motor controller if I use torque limits for hard stop homing.
This feature is great. Saves time and reduces hardware and failure points.

Im about to buy clear path SDSK-3421S-RLN for X and Y and then SDSK-3432S-RLN for Z axis. Just wondering for my mill should I get the HP models which cost a little more but then supposed to be very very good.

If this motor has an absolute encoder to memorize the position, why does it need to pump to a hard stop? you can simply home it once forever.

Before you waste time in these motors know one thing. I spent days familiarising myself on them only to find at checkout I cant buy any. Reason being is the firm only take credit card. After two emails I am finally told to go to motion industries and in doing so I loose money back guarantee. I pay more and they take longer to be sent to me.

One of these motor is over $500 and the established firm only take credit cards.
