When you create a New Profile the 'Profile Editor' button will appear.
You Only want to edit New profiles, not the Originals.
Some commands may have been deleted from Original file.

(appears that many commands have been Moved from original place in list,
so there may be others Missing also ? )

These are definitely needed:

"layerWidthMaximum": 0.4,
"layerWidthMinimum": 0.4,
"layerWidthRatio": 1.48148,

(If you have an unchanged copy of that settings file somewhere, you should start-fresh with it)

It's okay to Move them in list, but None should be deleted.
I moved the ones I change the most to top of list.

Note: I changed the layerWidthRatio to 1.5 on ours and that worked great

Nope, just uninstalled and reinstalled makerbot desktop, still no options for layerWidth anywhere.....
version is makerbot desktop beta v 3.8.1.231

Which is strange becuase when you search google, the makerbot website itself does list these as options, but then why are they not in the program???

Only thing I can do is add those settings in the text editor and hope it works.

I suggest you use Makerbot version 2.4
It is the Only one I've found to be completely compatible with our CTC
(I tried both 3.6 and 3.7, both had problems)

Don't forget that Makerbot software was designed for Makerbot printers, Not CTC printers

Note: our printer came with version 2.4 on a SD card

Argh, I keep running from one problem to another :P

I cant level my bed anymore.
First when I press Level Build Plate, the nozzles now are hitting the build plate, which is bad.
Then when trying to level it, I have completely loosened one of the nuts and the paper is still running loosely between the nozzles and the plate.

This was not happening before, no idea what to do about it :/


edit

I think I figured it out, the screws holding the Z switch at the back were loose so I think the switch was being pushed up a little before being pushed to stop the motor.

Man I didnt think just setting up a 3D printer would be this much of a hassle.
I mean I had to put the temps to 255 min to get it to extrude, now just installed makerbot 2.4 and it seems fine at 230 degrees again. It doesnt make any sense :P

Installed makerbot 2.4, but this gives you less options from what I can see. Do you have to do the rest manually then?




Well here's another print I've done, using v2.4, still the weave at the top though, with the layerwidth set to the before given settings.

And another, removed the rafting and as you can see, the base is even worse than the top!

And this time you can see the slicer has taken some weird paths for the first couple of layers

Sounds like it's still using the Old Profile (miracle.json file) used in 3.8 ?
Make sure to create a New profile, with New miracle.json file, when running 2.4.
And make sure those old corrupted Profile files have been deleted.
And make sure all the missing commands are There, in that New miracle.json file.

you could just use a gluestick :-)

Cheaper than acetone, and considerably more user friendly.

Have you printed a calibration cube yet with Simplify3d.. I've read people with our printer having wrong dimensions on prints... About to try Simplify3d myself now...

[bigo93]

No I've not gone into fine calibration yet, my last cube was 19.7mm, which is close enough whilst I get other bits set up.

For example, I installed those spring arm extruders yesterday, tried to do a print today and the bloody thing will not extrude. It wont even feed the filament.

It goes in, it starts to extrude but then a second later it just stops.
I think it may be a tension issue, but the only way I can think to increase the tension would be a longer stiffer spring.

i did get a print to start by pulling the arm up myself, but then the stepper motor started clicking as if the nozzle was jammed, but it did extrude.
At least for a few minutes before it stopped again.

Sounds like the motor does not have enough Torque ?
Maybe the Voltage from Mobo to motor is Too Low ?
Is voltage adjustable on your Mobo ?
( there are videos Online about adjusting that voltage )

[bigo93]

Doesnt look like it, cant see any potentiometers on the board to adjust.
