Luke11CNC Build Log ,I'm so naïve

[Jonathan]

Z-axis is in progress, plus Y-axis stepper motor mount:







I reground the cutter (6mm single flute) freehand after the Z-plate as it was chipped. Better finish than ever! :surprised:



All the bits made, mainly drilling and tapping to do now then check it all fits properly.

So close now

Something worth noting for the future is that the aluminium flat bar is nowhere near flat, so in future I will stick with getting aluminium plate like I used for my machine.

The BK support is partially dismantled in the photo as it's not going to work without modification. Glad I never considered using them on my machine, too much trouble compared to just making the whole thing.

Just a small up date the x-axis ballscrew has been re-taped and put back on the machine Thank you Jonathan

99.9 % of all components have been made so more images are due this weekend :naughty::naughty:

Jonathan has agreed to come over on the 19th to wire up the CNC Machine so in short 12 days and my machine should be cutting (Christmas is coming early)

Good to hear folks and hope you have lot's of safe fun designing and cutting stuff on the gantry Router. Best wishes and have a very Happy Christmas Season.

O my god o my god

I've seen it my z-axis running by a stepper motor up and down up and down thanks Jonathan

and I say

bring on the 20th, let me complete the cnc machine and play

I've already started to get prices on the 4th axis and will be ordering parts in three weeks

barley twists here I come

James and Luke

luke has started drawing his creeper ready for the cnc machine (bless him)

[Jonathan]

Few more bolts / holes and it's done:

Y-motor mount:


Z ballscrew fixed end, slightly unusual motor mount. Had to make longer spacer for the bearing support as the existing one wasn't long enough and caused far too much friction.


My router is accurate, but alas still a bit off square:




Made a quick nylon seal for additional protection as that bearing gets the most dust being right above the cutter:


Will post a video and more info tomorrowish.

they look amazing Jonathan

But image 1 the bracket is inside out, motor needs mounting on the other side Hee Hee

Oops, yes it does. It fits on both sides.

[luke11cnc]

Jonathan do you think we could make that third leg/mount adjustable ??

James

[luke11cnc]

So it look's a bit like this:tup:



Please note Jonathan this is not to scale

James and Luke

[Jonathan]

Yes I can and will change that.

Putting the DTI where I did to start with is a bit pointless, but using it to test the runout revealed the runout is 0.06mm measured about 10mm from the chuck, which is poor. It increases linearly with distance too ... so the cutter is held at an angle to the axis of rotation. I measured inside the spindle bore too, and it's the same.
