MachMotion Support Assembling The Tool Changer


Understand how to assemble the tool changer on a C.R. Onsrud Panel Pro CNC router.

Best Practices & Tips:

  1. Loctite all the bolts when you are putting the tool changer together. This will help ensure that nothing is going to come lose over time and use of the CNC router.
  2. If you are working with an existing tool changer, remove it from the machine to change out the servo and gearbox. This will allow you to have better control over replacing these parts and ensure that you are not stripping any of the bolts during the process.


Hi guys, it’s Josiah with MachMotion again. We’re working on the C.R. Onsrud Panel Pro and we’re assembling our new tool changer here right. So we’re going to reuse the existing tool pockets and the existing gearbox here. We’re also adding this new servo, a new Nydec gearbox, this custom spacer we made, and integrating it all to match up with this existing one. So make sure to Loctite all the bolts when you’re putting this together. We don’t want anything to creep out over time, so we use blue Loctite, torque these down to spec. Torque our gearbox to spec. We have a bushing right here with a coupler that integrates right into the factory gearbox.

So we’ve actually removed this from the machine, just make a little easier while we’re putting this all together. We don’t want to strip any bolts out or anything. We’re going to reuse the factory sensor. We have this optical sensor here to check for tool in pocket. We’ll reintegrate that with the software and we have our tool changer home sensor right here. So this is a PNP product switch that we’re going to reuse to find tool changer home. Now we have this all torqued together, Loctite on all our bolts. Everything’s solid. Gearbox is torqued to spec, nothing’s going to back out. We’re going to remove these little bushings here, put everything back in the holder on the machine, re-line up this tool changer, and then get set up programming it.
