LR32 holes on both sides of a divider?

[sprior]

I'm building a 3D printer cabinet with 4 drawers and a center divider and I want to have shelf pin holes on both sides of the 3/4" ply divider.  I'm wondering since the holes will/should all align with each other should I do anything so they don't or are they fine on both sides of one piece of plywood?

If you drill them through from one side to the other, they'll line up just fine.

I'm thinking that it wouldn't be desireable for the holes to go all the way through the divider so I'm wondering how it's usually done from a design perspective: do I drill them all the way through, will normal depth holes reach not far enough to meet in the middle, should they be offset from to back to not line up on purpose, or what?

Drill all the way through. If using the LR-32, there's a Festool 5mm bit for this very scenario.https://www.festool.com.au/dowel-drill-hw-s8-d5nl30-491064.html

I have that bit, but thought the use case was connecting two cabinets together via bolts through those holes.

Even all the way through, a standard shelf pin won't interfere with another one in a three-quarter-inch"/18mm board.

I used standard through-hole uprights for the center dividers on a Sys-port build with Sys-AZ drawers and had zero interference/clearance issues with screws from both sides.

Yup, one of our off-the-shelf veneered cabinets from the 1970s used through pins where the shelfs were at the same height. The pins looked like cut from metal rods so may not have been original. I remember hitting this sometime in the 90s when we repurposed the cabinet to another room and needed the shelfs set to different heights.

the LR32 kit comes with 2 bits. One for drill stopped pin holes the other for through pin holes

We cut them all the way through whenever they are needed on both sides of a single panel. This is in a production cabinet shop, and it's mostly about speed. Turning parts over and doing a "secondary operation" on a CNC machine is just not desirable. Sure, it can be done (and sometimes it has to) but you are dealing with one part at a time at that point. The efficiency is gone, since normal production would be getting 6 base cabinet sides from a single sheet. Done and pushed off to the edgebander.

...also, you can get long shelf supports, designed for through holes.
