DMC2 Mini Mill - Another build and review
- Thread starter Feeop
- Start date
Day 1. Basic frame and X/Y linear rails, and lots of nuts and bolts.
Only one little issue.
1. Had to enlarge a couple of holes in one of the short tubes.
So far, a descent kit to assemble. Parts are well made, machined and finished. The alignment tool helps but it will require some tighter tolerances.

Day 2. Ball screws.
Issues.
1. I installed the oil nipples that can with the ballscrews. Wrong ones. The 4mm ones are in a bag with the oiling system parts.
2. Way covers for the Y axis are a bit fiddly, but they'll go on, just take your time.
3. The backlash system is weird (stacked flat and lock washers). I'm sure a good spring could fulfil the same function.
Otherwise, moving along.
Cheers

So far only minor issues. Couple of holes out of alignment but a bigger drill fixed that and today I was missing the X axis mounting bolts. Fixed by a trip to the hardware store.
Day 3. Way covers, oil lines, bed and start the Z axis assembly.
Issues:
1. Missing X axis mounting bolts (4)M6x45
2. Zip ties to hold the way covers to the linear guides is cheap and fiddley but works (we'll see).
3. Really hard to tighten the Z axis ball screw nut once the assembly is done as per the instructions. Had to remove the ball screw nut bolts and slide it out from behind the red plate, then use a very thin walled 7mm socket to tighten. Then loosen all the red plate bolts to get the ball screw nut back in and tighten all. Need patience here.
Otherwise another stellar day of doing stuff I enjoy.
Cheers all.

zip ties for way covers interesting, sounds like and looks like its coming along nicely for you tho. Im thinking ill be picking one of these kits up this week
It does get a little fiddly at times but it's progressing ok.
Day 4. Z axis assembly, bed level and square, oil lines
1. All went pretty well. Some places are a little hard to get a shim into but it's doable. I had to add a .002" shim to both sides of the X axis in order to get the Z & Y axis squares.
2. The oil lines are a little tight running up behind the Z axis but the will fit, just don't cut them too short cause it's a B to swap them out. LOL
3. Starting to get a little heavy to move around.
4. The last thing I was working on was the sensors for X and Y. The X one is impossible to mount with the hardware provided M4x25 & nut as I can't get the nut into the tube as there's 2 other screws in the way from the rear X axis rail mounts. Might have to remove them first. We'll see tomorrow. The sensors also need to have the mounting holes drilled out a size or 2, so take it easy. They have their own mounting screws, but cheap ones. I'm also going to glue the X sensor in place as only one screw will fit.
Tomorrow's another day. Cheers

Day 5
Main assembly done, on to the outer shell.
Issues: X-Axis sensor really difficult to install bolted thru the small frame tube.
X-Axis was a little tight at the motor end, but only had to knock it a touch to the left and it runs good now.
You will have to separate the X motor coupler to get that piece in as per the instructions.
Note the added allen key to make each axis easier to move during adjustments. Works great on a cordless screwdriver, which is also a great thing to have.
Mike R has really good assembly and setup info in his post (DMC2 Mini Mill - build and review). Thanks Mike
