The distance between BK12/BF12 fittings is 46mm they do fit but it's less than perfect, my gantry is fit like this. I made adapters for my bottom axis (With the proper 46mm spacing) and you can tell the fit is better.Quote:

Personally if I build with extrusion again I will make adapters for all the BK/BF fittings. (A non issues for the Z of course)
T Nuts are expensive here I spent £45 on just over 100 to fit my Hiwin's.
Ouch! I bought 50 tnuts from aliexpress for around 10-12£ with shipping included.Quote:

Got ahold of grease nipples for the ballscrews and lithium grease today.
Good news, the slides run much quieter and maybe a little smoother. The ballscrews are definitely quieter!
Bad news, the end seals on the linear bearings leak a bit of grease :( might just be that I tried to fit to much grease :D
I pumped once, slid the axis back and forth for distribution and then pumped again and got leakage. Normal or bad quality bearings?
Worse news, after greasing the ballnuts they spew out dirt and debrie from the seals unto the ballscrews. Should have cleaned them before screwing everything together!
It's not so many screws to dissasemble but the end bearings are pressed on and I don't have a proper remover (don't know the English word for it) damnit!

Nice for the son that say little not understanding words already, I now that the free time is too little over there,I am just teasing you since I do not have nothing better, about cnc stuff to do,lol!
And please post that Z axis work , since this is the most complicate work for me to do....haha.
Ps I spend two hours today at Airport customs ,grate experience ....:toot:
Small ghetto update today!
Made a bracket for my y axis.
Had forgotten to calculate with the adapter plates for the bearings that I made so I had to add a spacer :(
Also my aluminium stock is running low :D
Had to use 2pcs of 4mm thick aluminium for my bracket instead of the planned 10mm. The upside is that I could cut a hole through the first piece for the ballnut bracket to fit. Had planned to pocket into the 10mm piece. Now I didn't have to :)
Also I did a motormount for the Y motor.
Will revisit it sometime later with a file and some different screws ;)
And some pics

Realised this is the same problem with my holes for the spindle bracket :(
Really have to remake the Z axis dropplate and make it work soon ;)

To bad that it's a part that I can't remake myself but have to get cnc'd
I'm way to bad at marking and drilling holes accurate even if I order flat aluminium hehe
