New start

Sounds like a plan. You would need 3 rows of 5 all in parallel and tie them together with a big zip-tie

Small update.. as usual Im doing a little work everywhere :D
Made some adapter plates for bf/bk bearings.
Started soldering my capacitorbank aswell.. but no pics of that til it's finished!

When you work on the machine for 30-60mins per day it feels like nothing is progressing.. Wish I could get a whole day to spend on this ;)

Some pics for those who want to see..

Nice to see that you have make progress!
The extrusion you use has 10mm slots? From where did you buy the T nuts?

Nope!
I have 8mm slots with 40mm between the slots. That's why I had to make the adapter plates for the gantry. With 45mm extrusion the bearings could be bolted straight on.
Found this out to late in my planning.
Already had the side plates made.. ;)

One thing to do different with mk2 :D

I bought a bag of t-nuts from ali express.
They cost crazy money if bought locally in Sweden ;)

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.

look under P

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.

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!
