MOUNTING Y-AXIS SERVO MOTOR

Learn how to mount the Y-axis motor on a C.R. Onsrud Panel Pro CNC router.

How To Step-By-Step:

1. To mount the Y-Axis motor, first establish if you are keeping the existing adapter plate and ball screw pulley or if you need to fabricate/purchase a new one to fit appropriately. Additionally, you will want to make sure that if necessary, you have a motor adapter plate for the back side, like in the video.
2. Next, take the new Y-axis motor and drop it in, making sure that all the connectors are in an accessible place where they can be hooked up later in the install.
3. Tighten the bolts. Consider using a retention device – either a lock nut, a lock washer, or some blue Loctite. Put a little bit on the mounting bolts for security. Leave the tensioning screws loose for now to adjust the pulley.
4. Then, set and adjust your pulley. Make sure it’s lined up with the existing one. If you are keeping the existing pulley on the ball screw, nothing’s going to change here.
5. Next, add your new belt (or existing one, if useable). Slide on the new belt and adjust with the pulley for a snug fit.
6. Lastly, you can tighten everything down. Make sure you don’t have any belt walk here. You want everything to be lined up perfectly so it’s never going to rub.
7. Now, your Y-axis motor is mounted and you can continue with the rest of the CNC upgrade installation!

Hi guys, it’s Josiah with MachMotion again. Today I’m mounting the y-axis motor on this C.R. Onsrud. So we’ve kept the existing adapter plate here. We’re keeping the existing ball screw pulley. We’ve made a custom motor adapter plate that’s on the back side here. So first step I’m going to take our new motor and I’ve already paired it up and made sure it fits so we’re going to drop him in. Again, I’m making sure that these connectors are in an accessible place where I can hook the motor cables up when everything’s done here. We get the first bolt started.

All right, great. All right, so I always like to put some retention device so either a lock nut a lock washer or in this case we’re gonna use some blue Loctite. Put a little bit on there. That’s just security for down the road we don’t want this to fall out. Okay, we’ve got the motor bolted on and we’ve got everything tightened down so we’re gonna leave our tensioning screws up here loose for now so we can move this back and forth.

We’re gonna go about setting our new pulley on here. Make sure it’s lined up with the existing one. Again we’re keeping the existing pulley on the ball screw nothing’s going to change here. So we’re actually going to add a new belt here and a new pulley. Slide him on what I like to do is put on the new belt we’ll just snug this up for a visual now. We’ll line it up best we can by eyeball and then before we truly tighten everything down we’re going to run this screw back and forth for several rotations and make sure we don’t have any belt walk here. Want everything to be lined up perfectly so it’s never going to rub. Okay, so we’ll tighten our set screws in the back tighten down our tensioning bolts here get it set to appropriate belt tension, and will be set on the y-axis motor.
