Don't do what I did.

Moments ago I was approaching the end of an entire day of plunging holes for hinges, shelf pins and drawer slides using my LR32 in a total of eight frameless birch cabinets - a mix of shallow base cabinets (with a single drawer and two doors beneath) and double and single door upper cabinets. This was the last step before moving over to the domino, having already cut all the panels to size, edge banded the panels with solid maple edge banding (using a router bit set), flush trimmed everything, routed the grooves for back panels, etc.

Let's just say that while beginning the layout for the center and back holes for the 9" Tandem slides, I stumbled on the fact that the stops on the LR32 end stops had, at some point earlier in the process, moved.

Neither one was any longer set to 37mm and what each had moved to was different (one was set at ~39mm, for instance, while the other was something different).

I am gutted.

In essence, most if not all of the side panels for these cabinets are now ruined. All because I failed to double check that the knobs on the ends stops were sufficiently tightened down. When I did check (after I identified the problem) I found that each had backed off slightly from fully tight (we've had wide temperature and humidity swings over the last week which may have contributed to this loosening) - enough to allow the stops to move.

Another factor is that most of the upper cabinets feature balanced side panels (800mm tall) and the force I was using to ensure that the pins on the stops were kissing the front of the panels, force required to nudge the guide rail (thanks to needing to overcome the snuggly sandwiched end stops and the sticky foam under the guide rail), was apparently enough to knock the stops off their settings.

Awesome end to the week.

So, now I'm contemplating sourcing some 5mm birch dowel stock to plug all the holes. But I think that's just a desperate hail mary given that these cabinets, like the others I've already fabricated and installed, were destined for a clear finish.

These are kitchen cabinets for a rental unit that I own and operate. So, I'm not sure how terrible a bunch of plugged holes would look when all is said and done. I'm just trying to justify not having to spend a(nother) small fortune buying more plywood to remake all the side panels. I've got plenty of maple to mill more edgebanding out of so the plywood (and all the wasted effort to date) is all I'd be overcoming. Of course, really, this is about my ego, my being embarrassed but also my wanting to present a professional product to future tenants. So, maybe I'm being too vain. Or maybe, by sharing this mistake here, I just need to vent my disappointment.

Anyways, the moral of the story is this: always, always, always ensure that the end stops are set as intended and regularly crank down on the knobs to ensure that nothing comes loose. Live and learn. :(
 
OK, the plan is to flip the panels when possible and make a few replacements (for ends that are visible) as needed. I can live with the interiors of sandwiched cabinets being the "bad" side of the plywood so, in the end, the damage isn't as bad as I originally estimated. It's still more work but I can live this as a solution. But my warning stands. Tighten those knobs! 
 
Glad you can flip the panels. Will make for some minimal rework.

Not that it's necessary, but another idea if you were unable to flip the panels would be to route a 5mm wide groove vertically through both columns of pin holes to, say, 6mm depth then glue in a 5mm wide piece of birch 6mm ply. It would look interesting besides working around the problem.
 
I had that happen once and ended up plugging the holes with a dowel and then glueing a layer of veneer over the affected side before redoing the holes.
 
I'd visit the store where you can purchase the 5mm dowel rod, find a reasonable match to your birch panels and try doweling a couple of the errant holes and see how they turnout. You may be pleasantly surprised because when the panel hole is redrilled, there won't be much of the birch patch left to see.  [smile]  If you can match grain direction and color the patches do blend in.

Another approach is to purchase a 5mm plug cutter and cut the face grain plugs you need yourself. That way it's easier to match the grain direction and color.

Here's a plug in Jatoba from a distance of about 8" away.

I suspect many of us have had similar issues at some point with the LR32.  It happened to me once while building some sys ports to go under my out feed table.  I would do as others have suggested and attempt to plug the holes.  Good luck!
 
Trim all the panels so that the holes are correctly aligned and either lower the overall height of the cabinets or glue some edge-banding onto the panels to bring them back up to the original height.
 
Could you veneer the interior of the side panels to cover the holes and redrill?

I also like Bohdan's idea of trimming the cabinets to align the holes properly. 
 
If the holes are for drawer slides, why not plug them with 5mm dowels and redrill?  They would be under the drawer slides and hidden after the slides are installed, and will your renters be inspecting the inside of the cabinets with alot of scrutiny?
