It is different kind of approach to calibration, but not difficult at all.

It might slightly overrun your budget, but I would take this one:

Very precise and a lot of open options to manipulate your scans.

Did you try to reduce Model to raft distance?
By Default it is 0.23. Reduce it to 0.18 maybe.

Go to Filament Load and while filament is loading, look at the back of SE.
Silver wheel should turn.

This is where wheel is connected to the Carriage.
If it turns properly while Filament...

Hi there
you can try and open SE to see problems (if they are there).
But most simple solution would be - get yourself new SE and make sure it is SE+

Hi there
make First Layer Raft = 30mms
temp of Right = 230
Heated bed temp to 105
And don't forget to turn off FAN from 1 layer if you are printing with ABS

you have broken end-stop switch. Replace it and this problem will be fixed.

try to run Level Build plate again. This time without tighten knobs at the begining of the process.
If this doesn't work for you, then simply try to manualy level plate by printing some simple...

This ans some other features is reserved for future releases.

your Rep2 look quite a mess. It's dismantled and has several issues.
I would strongly suggest: take it to Makerbot Service center.
They will know how to fix it the best.

Howdy
I have it done and works just fine.
Go ahead.

this "zig zag" pattern happen when there is not sufficient tension inside nozzle.
Filament load before print usualy solve this issue.

howdy
they look different since there are actually 2 pieces, but on Thingiverse is all combined in one.
Just print it and you'll be fine.

Howdy
look like you didn't place it on the table properly. It's tilted up from back side.
This is why it doesn't show first layers in preview.

First you should Level your build plate accordingly.
Then unscrew extruders from below, both of them.
Don't take it apart, just loose it.
Then stick thiny piece of paper or kapton tape on...

What is going in with pulley? Does it rotate at all or not?
Motor itself doesn't fail just like that.
I would take a look at rotational parts, if they are tighten properly.
There is a...

Try this one:

Of course.
There is only one SE and it is the same for all units.

SE+ is definitely the must.
I have Z18 for 1.5years so far. SE was kind of weak point of it, but managable.
SE+ is much better, we produced great prints with no efforts compared to previous SE.

Howdy
If I would be at your place I would start by testing different printers with the same sample of your part.
Take one, very representative, with all those details you would like to see...

Howdy
Shortly said: one can use ABS on Z18, but with a lot of patience and knowledge of course.
Heated chamber can heat up to 55dc. This alone is obviously not enough for successful preventing warp...

Hi there
look like you have PCB failrule. I don't see any other option.
You should take your REP to Makerbot service and they will fix that for you.

Hi
If platen is moving then it has to be replaced.
Or you can take it to MB Service center and they will fix it for you.
