You can always use a small washer in between the coupler and bearing. Make sure the outside diameter of the washer isn't to big. This should space the coupler out enough to clear the bolt on the coupler.

I tried the washer spacer but then motor side coupling sticks out too much.

Wow really, so you can't install motor

I'll have to check my mini raptor in the morning, I'm at work tonight :-(

Anyone found any trouble getting the Y screw on? The motor coupling screw is rubbing on the inner spacing of the upright. Took the screw 3 times off and still not getting it aligned. Should the coupling be touching the bearing?

Do you have the Y axis plate on when adjusting ballscrew? In picture i don't see it on , Sometime the bolt on coupling sticks out more than others. I see couple burs on bearings wall on upright in picture .

You would not need to use a spacer or anything

Y axis block was on. I took the ballscrew off to send picture of the coupling location. The coupling screw was hitting the bearing wall and scratched it.
I will file the coupling screw. What happens when I need to remove the coupling after though?

One last wrinkle on install. Last motor going on, X axis. It looks like the NEMA 34 shaft is too long for the adapter plate by just over 1/8". At this point I am tempted to just cut the shaft down to size. I have lots of clearance from the motor and can seal it so I don't fill it with filings.

Anyone with experience trying this?

Thanks
John

Nema 34 mounts were designed to fit 1 inch frame, you will have to cut shaft a bit to fit or a spacer. Shaft you can use hack saw or cut off tool.

I bought one of these:

NEMA 34 Adapter Plate Spacer Motor Mounting Linear Slide Stage Actuator | eBay

One was enough for a perfect fit.

Thanks George. I'll shorten the shaft. I looked at the spacer option, but the motor would be hanging way out there and thread depth into the frame is not as much with the 3/4 inch frame.

I had to shorten the m5 screws for the motor mounting plate, looks like m5-32 fits tight without bottoming out.

I know this stuff is probably all a non-event for a machinist, but drilling out the exact centre of a coupling, then cutting down the shaft of a brand new motor are things that a newbie may or may not be able to handle on their own.

I have an order going to McMaster Carr shortly for the low profile grease fittings. I was thinking of ordering two couplings from them to see if they are compatible with the ones that are already mounted. I know finding a 1/2" coupling is a challenge, what do you think of this part? Pricey, but....

Done and fits! For anyone else who has to do this, I'll offer the following:

I had 1/8" hard plastic (polycarbonate) pieces which I could drill a 1/2" hole for the shaft through. this became the guide and protective face for my hacksaw. Sliding the shaft coupling all the way to the motor housing and tightening it flush to the housing face, then adding the 1/8" plastic left me exactly where I needed the cut to be and offered a flat reference face as I rotated the shaft every so often to keep the cut square. A good bi-metal 32 tpi blade, cutting oil and patience, et viola!

George, any experience with this adapter? I am struggling getting my PCI parallel card to work.....

Will you be stocking them and if so, any pricing info?

Thanks
