ROUTER lock button hard to press. tolerance or assembly issue?

Hi everyone, first time poster here. Just got my Maslow 4.1 last week and stoked to start cutting! I was able to assemble it, perform all the software and firmware upgrades and currently at the point of putting in a bit and do test cuts. However, I’m having a hard time holding down the dewalt lock button to tighten the bit. I went ahead and ordered the 3d printed “lock key” , collet and ratchet from the not-store.

I’m anticipating I will still have issues with the lock key not working.. see image labeled A, B, C, D: Parts a and b forces a fixed height for the stacked arms that wraps the dewalt router, causing a gap ,c, which in turns making the press lock button hard to press with attempting to change bit. Is this a tolerance issue with parts A and , or did I mess up on the assembly? Thank you!

If the gaps at “C” is closed, the bottom plastic plate here would go up a bit give me full access to the lock button.. I can’t hold down the lock button long enough to tighten the collet. It’s just a really awkward position for my thumb :confused:

That gap is normal. Try this version for locking button, makes it a lot easier to fit router bits. Do you have access to a 3D printer?

There is another version here too: The Not Shop — Maslow

I agree it’s really a pain without a pusher

Love this one. I didn’t get the orientation at first, and Im still not getting the placement or use of smaller semi-circle. Where does it go?

The hole punched in the larger semi circle is for “remove before flight” tag?

Guessing you solved this by now, but, at a glance, id say the top plate is rotated 90º off center, causing the bearings and top plate to disagree and adding this gap.

I downloaded and printed the button lock from the Not Shop.

I just tried to use it and found it was very difficult to fit in place. It needs to push the button in order to fit in the space, but the slot gets stuck ON the button and does not push.

I finally was able to get this to work by using a large Allen key to press the button while I rotated the collet until the button found one of the slots in the shaft. I was then able to insert the button lock.

The next challenge was removing the button lock. It was tight. Perhaps it will loosen over time.
