Hi all. I’m looking for other trim router options that work with my OneFinity Woodworker CNC. I’ve experienced a bit too much runout with my 1/4 bits and have had bits slowly creeping out of the collet. I’d like to purchase a higher quality collet but options are limited for the Makita. Considering Bosch or Hitachi
we have a search function here. You may have found that
the only options currently possible with the Onefinity are 65 mm routers (so the Dewalt or the Bosch won’t fit) or 80 mm for spindles
the Makita hand trim router and most of its clones have a proprietary collet system that holds the bit only at the front of the collet and with which bit holding issues are common
That there exist Makita hand trim router clones with real ER collets.
See here for comparison.
Note that for a spindle or router for ER11 collets, you get collets for bits with 1 to 7 mm bit shank. That means with a ER11 router or spindle, you can use bits with a 1/4" shank by using a true imperial 6.35 mm collet or a normal 6.5 mm metric collet, but bits with a 3/8" (9.5 mm) or 1/2" (12.7 mm) shank cannot be used with a router or spindle for ER11 collets. For 3/8" (9.5 mm) bit shanks you would need a router or spindle for ER16 collets, and for 1/2" bit shanks you would need a spindle for ER20 collets which will take up to 13 mm bit shanks (1/2" = 12.7 mm).
A little bit of redesign would allow the 1F to hold various sized routers/spindles.
I built a horizontal mortising machine that used two hose clamps & a Vblock to secure a full size router with a 1/2" collet, never had a problem with router movement.
Granted that the loading on our CNC’s is higher than on my mortiser.
if they were willing to design something, I think they could (should?) offer a mount for what many consider as → the best milling motor solution for hobbyists and semiprofessionals for the Onefinity.
What I am talking about is the milling motor type that is widespread around the world, a motor dedicated for 24/7 CNC use (and that does not loose its warranty as soon as you mount it into a CNC, as Makita stated for their Makita hand trim router), with all-steel motor flange and double ball bearing, a control interface for controlling speed by the CNC controller via g-code, run-in by the manufacturer, but at same time no VFD, no custom wiring, works out-of-the-box, simply plug-and-play on a domestic socket.
Such a 43 mm “Euro” mount that Onefinity could offer would look like this:
It is a feature requested as of 2023-Feb-28.
Was thinking along the lines of using a flat plate which carried the bearings and nut, to which one could bolt up a range of spindle holders. Make it so that it was not too onerous to swap spindle holders for a specific job.
I have the MakerMade router with the real ER-11 collet. This is made for a cnc. Works like a dream! Doesn’t get hot like a Makita and the actual collet holds the bits much better. The speed control has actual indents that prevent it from changing speed. It is a 65mm fit.
If you get something with a real collet, make sure you read up on how they go together and work. It’s not like the cheap Makita.
Awesome reco, thanks Pony
Having such a universal Z assembly plate on the Onefinity would expand the capabilities regarding spindle choice to a considerable extent. In fact it’s what I plan too. See here for a more universal Z assembly
And so I’m buying a new Journeyman.
I want to but separately a spindleIts more powerful and quieter.
Air cooled seems best (no water tubing).
I prefer a 110v.
Also this will be wall mounted so I don’t want a heavy monster.
It makes sense to be able to use 1/2’ shank bits.
There are different ER ratings 11, 16, 20.
What are most Onefinity owners using?
So which should I purchase?
Thanks in advance.
If you want to use 1/2" shank bits, you will have to take a 80 mm spindle, as you will need a spindle for ER-20 collets, and such is not available on 65 mm spindles. But 1/2" is rather thick for a bit shank. When I had to choose a 80 mm spindle, there were spindles for ER-16 but also spindles for ER-20 collets. “If I don’t forcibly need to use bits with 1/2” shanks, is there another reason to select the one or the other?" I asked the spindle manufacturer. See below
So we finally bought the ER20 model.
Daniel, you can use 3/8ths bits in the Makita, the collet looks quite a bit different, but they will run as well as a 1/4 " bit. Not certain of the actual reason for this but if you insert the 3/8ths bit as far as it will go, the end seems to come into contact with a taper inside the router shaft so the bits seem to run very true. Of course the Makita is not going to like working that hard & probably wont last long, mine only lasted about 4 months. with occasional use of 3/8ths bits.
