Alexa's (It and my niece were named long before amazon stole the name) back up and running.
And looking new and shiny.

So here's the thing.
I wanted a single heatblock.
ended up buying a...

Well I guess i just jinxed myself.
The ptfe tube was buggered, So drilled that out, fitted new one and managed to twist the end off the nozzle leaving the thread in the damn hotend !

So...

just changed my nozzle, I believe this is the 3rd 0.5mm !
They are dirt cheap brass - so I don't expect them to last forever. They're averaging about 1,75km a nozzle. Which doesn't seem...

well I suspect the printbite issues were as much climate and cheap pla related as anything else.
Just run through a roll of black esun pla that came with the klic-n-print. Switched back to some...

yes - get the aluminium extrusion pre - threaded by the suppliers.
The build kind of ground to a halt when i broke the threading bit.
Then maneged to strip the threads on another strut and ran...

haven't got round to buying a new horizontal strut yet. Currently spending most time on the laser engraving.
Also come to the conclusion that I need to buy pre-threaded struts.

Plus it's bloody...

3mm bungee cord arrived today.
Going to be perfect for the suspended extruder.

I still don't know why it needs to be elasticated. But as every suspended large delta I've seen has an extrduer...

alas I showed darren and he said 'you need an engineering firm for that'.
Apparently even though it says engineering in their frim title - they don't have any of the right gear.
Don't even have a...

Oil ? Nobody mentioned oil to me - bugger :-(
makes sense, but dave never mentioned it - it's all his threading kit, so it must be his fault lol
He knows I don't do much metal working.
Guess...

Marked out and drilled prinbed today. Then decided might as well attach printbite. Keeps it safe and flat. I'll wait to attach the silicon heatpad till I'm messing about with the board and motors...

so put most of the frame together for the first time last night.
I'm beginning to think building a printer I have to stand on a chair to do the electronics - maybe wasn't such a good idea after all...

not going to be quick - each corner piece is now up to about 5 hours printing. 127gms.
so i can get 7 and a bit from a reel of filament.
If I take infill from 25% to 20% - I can get 8.
(quick...

so after something of a break, I'm back on the big bastard.
What caused the hiatus was cutting 6mm threads in the ends of the aluminium extrusion.
I had been using the thread cutters in my drill....

3 seems fine for me.

Printed a big mould set last night. 0.4mm layer height, 100mm/s - came out perfect. Did it in clear pla - which can be tricky. No problem.
New retraction settings give me completely string free...

well I'm over halfway through the i3 parts and no issue so far.

Belts are tight. Also bear in mind I have two belt tensioners on each belt - so all three are at the exact same...

Currently printing a 2 part 'thing' (one of my inventions I sell - so no, I'm not telling you what it is :-) - doing both parts at once - no problems.
One is about 30mm tall - still on 0.24.
It's...

yep, I can feed as much as I like, temps are stable.
The tubes I added to the extruder are fine, nothing's getting stuck on them.
Plus it's doing it on both normal pla and flexible pla.
I've...

Just knocked out a 100mm statue of ganesha at 0.24 layer height (try to keep it in multiples of 8, the stepper motors prefer it apparently).
Bang on - zero signs of any issue.
I mean none - got a...

Well I'm still not sure if there is an issue with alexa or not.
If there is it seems to be proportional to the layer height.

ie: if \i print at a lower layer height, there is no discernible...

I'm still not entirely sure. I used my angle ruler thingy (it's a weird looking bit of kit) and I still can't say for certain if it's actually slanted.
Oh yeah and the flashforge decided it wasn't...

I'm getting paranoid. Test part looks fine, but I keep trying to see the slant. lol

screw is infinitely adjustable.

I've got all three within 2 100ths. It's good enough.

Got some i3 parts to make for someone, interested to see if they come out okay.

lol I'll stick to the three point and screws until it stops working :-)

yep - after a short while you forget all about the print sticking and releasin part of 3d printing and just get on with the 3d printing.
All the messing about with glue, freezers, tape etc - just...
