- Installing the X- Axis of the BD Tools CNC Kit.
I was going to use the stock dowel pins for the end plates, but they were a bit tight so I removed them (You might see them disappear when I'm attaching the motor side end plate).
FPV is a lot of fun on multirotors. I'll watch for your videos.
Yes I think my table had ribbing underneath. I don't know why my Y axis channel was off center. It made the cnc conversion more difficult. The x axis did as well. I wonder if Billy modified the x axis ends slightly to bring the ballscrew up a little higher?
I'm very happy with the kit from Billy. It's very well made, nice finish and excellent support from Billy.
I have made my own motor mounts (for a Seig X2) and have had other brands of complete kits (CNC Fusion) and I much prefer the kit from Billy to those.
Are you using the BDTools mounts the same as mine or the Optimum Kit? I'd love to see close up videos of the belt drive kit from optimum installed and running on a BF Mill.
From the top of my Billy end plate to the top of the Ballscrew end (machined to 12mm OD) is 33.25mm.
Thanks a lot (I got myself a HT-FPV frame after watching your videos...).
I have plenty of clearance under the X ballscrew, I was surprised I only had to grind a pocket for the X Ballnut. There was some casting flash at the front of base that I thought might interfere with the Y Ballnut, but its pretty well centered.
Does your table have ribbing underneath?

Hi guys Im really new here I have a new G0704 mill want to upgrade , how is Billy that sells the upgrade kit ?
Thanks for the heads up - that would make sense. I'll check them (when I can find them).
... this was because my ballscrew was a tad shorter than I would have liked. The second thing I needed to do was cut a pocket on the saddle under where the x ballscrew will run. On mine it was rubbing very slightly. You should slip a piece of paper under yours and see if it is clearing. I really enjoyed watching your videos.
I did the same conversion on my g0704 with the parts from Billy. I watched your videos and noted some things you did not do that I had to do. On the Y axis I had to grind the inside as the ballnut would rub one side. For some reason mine was off centered a fair amount. I also had to grind underneath at the front to allow the ballnut to clear. This was because I mounted my ballnut adapter on the other side. I was worried that at the end of travel the ballscrew might come out of the ballnut.
I did this conversion completely DIY and used Nema 34 hybrid steppers with closed loop system (12Nm.. real heavy motors) and I absolutely love it all in all tool me 2, 5 days then everything went absolutely as I hoped it would
what size an type are the motors
I was just putting MY end plates on yesterday. At first, saw what you meant meant about the dowels and removed them. Then noticed - they're tapered pins! They have to go in after the end plate is installed, with the bolts loose. Pin end with the hole is the 'fat' end.
Hi! Congratulations for this jobs in cnc. Is the motor pap of 34 nema? or How nema the motor pap it got? Thanks.
I'm using 570oz/in, NEMA23 steppers for all the Axis.
ok thanks.I have the same machine and I'm interested in cnc turning. Greetings
Did you had any problems when lifting the Z axis cause of the head weight?
can this machine work on Drilling 6mm holes length of 6mm or abit more?
I got almost all parts except that nut you have put on ballscew after you mounted motor bracket. Do you know what size i should look for to get them?
The Coupler? I'm using Lovejoy LO-50 3/8" to 3/8", which match the diameter I had the Ball screws turned to and the diameter of the shaft on the steppers. You can get them in different sizes on each end to match whatever you go with.
I got mine on eBay, you can search "Lovejoy L-050" plus the size you need for the different shafts
You can also use Oldham couplers, they are a lot more expensive, but work better.

The specifications for this kit would be the 1 7/8" long, 1 5/16" OD and then pick the shaft diameters.
(If your talking about something else then let me know the time it appears in the video and I'll get back to you.)
Thank you that is useful to know (i got some cheaper couplers for now) but i was refering to nut you have put on ballcrew to tigthen it up against bearing on 2:02 time in video.
Thats a regular 12mm nut. When I ordered the Ballscrews I specified an M12-1.75 thread there, I forgot to ask for lock nuts and just used two M12 nuts "double nutted" instead.
Thank you very much. I didnt got those at all.
Why do you wear gloves, that Chinese mill is not so sensitive machine. Are you protecting your skin ?
It's so I can take them off when adjusting the camera so I don't get oil all over it and the tripod.
