Yes super happy with it.
Need to do some mesurements to check for obvious F ups ...
Only have some old analogue calipers ...
Need to start buying some quality measurement tools help with aligning the rails.
And i am hoping piano wire can help with aligning...
I have some quality 140cm 8040 profile that can be used with straightening stuff.
Bouyan said one needs a 1000mm straight edge and machinist squares..
He is right i think...
Need to start figuring this out.
So...
I am about to order linear bearing parts.

Bom ordered BST Fred.
Anyone with experience from NL here?
I am curious about how this will work with dutch customs..
I understand carrier will report to tax administration..
My estimation is about 27% extra cost.
21 vat 5 import and some minor handling cost.
Guess i will pay tax and handling cost to carrier..

Guys, thanks for recommanding Fred from BST.
Everithing looks good and well packed.
Some heavy cardboard box reinforced with multiplex all wrapped in plastic foil.
2nd attempt at pouring epoxy is underway.
Tomorrow ill visit the local tool station to go and get m5 machine taps and some nico 4.2 drills.
Also.... need to source some Alu tooling plate. for gantry.
And have some 20mm mdf cut for test fit.
Its gonna be busy holidays.

Well i am not sure yet.. fedex delivered... i paid Fred... But i have not been taxed yet..
I guess it will be in the +/- 1300.- euro range.
I understand sometimes you pay tax in the country where goods enter EU.
That would be belgium..
Grtz. Bert.

You are planning well ;)
As you have read the straight edge will simplify your life and keep your hair from being grey :D
I did it the sloppy way!
Read about someone who placed the linear rails beside each other and checked for gaps.. if there are none you can flip one and if they still are without gaps they are straight..
I was lucky and had two straight rails that I could align the first long rail with. Could not get a feeling blade inserted anywere on the whole length of the rail.
For the matching rail I mounted the gantry and slid back and forwards, drilling and tapping one hole at a time as close to the gantry as possible.
For the gantry rails I took a steel ruler that I checked against my master straight rail..
Straight edge and square is better I think ;)

Well... need to say...
Disaster
Something went wrong ....
There was a tiny leak.
It leaked on the surface of Xaxis... it sucked inbetween the gantry and bed...
I did make preparations to prevent this.
I sprayed wd40 inbetween before pouring.
So nothing could stick.. worked only partially.
I needed a hammer an chisel to separate the gantry from the bed.
1 side of the x bed surface delaminated from the steel ....destroyed .
So deep breath ... cleanup and do it once more...
Grtz Bert.
