The nice thing is that if you need different version on python you can install them, you just have to remember to point ReplicatorG at the right version of python. Now download the latest version of ReplicatorG for whichever platform you are using from Version 0040 is the most current right now (and likely forever.).
Summary This makes slicing STL files two to five times faster when using ReplicatorG and Skeinforge. This is done via an alternative Python interpreter (PyPy) which is much faster than the default one. This is a pre-compiled version for Mac OS X only.
A few steps to keep the MakerBot running smoothly and continously.

Setup
Mechanical setup
The basic setup of the MakerBot replicator is quite simple, below is a compressed version of the official guide.
Open and remove the top large cardboard piece along with the user manual and take the entire Replicator out of the box
Slide out the large accessories box and open it to take out the extruder and place it on the extruder platform
Move the build platform up by pulling on both of the inner back supports of the build platform to remove the cardboard piece and the two filament spools
In the accessories box, find the two black hex screws and fasten the extruder (the washers are for the extruder plunger maintenance)
Add the rubber feet to the side panels under the bot to dampen the vibrations and increase friction on the MakerBot's working surface
Refit the heated build platform cable below the platform to the bottom plate, adjust position of the cable to limit slack
Press the black filament guide tubes onto the extruder holders and clip the guides in place on the back
Hook the spool supports to the back of the MakerBot, with the top tap going in upwards
Unpack the filament spools and put them onto the support with the filament pointing from the bottom and up towards the center of the backpanel, cut the bent end using a plier and feed them through the guides till they hit the extruder
Find, or use the supplied US, power cord and plug it into the adapter and the other end to the four pin socket on the Replicator
Lastly, flip the power switch to power up the bot and and skip to the next section to perform the software calibration
First-time calibration
The first run experience steps below tunes and sets up the build platform and extruder.
An automatic setup script will be displayed on the LCD display, press the middle 'M' soft key to continue
Tighten the thumb screws on the underside of the build platform to make sure the platform does not hit the extruder nozzle/heads
Adjust the height of the platform by loosening two screws at a time as per the instructions, repeat the calibration one more to fine tune the platform, use the included MakerBot business card and aim for just a hair above, card is 0.12 mm and printer resolution is 0.20 mm
Heat the extruder and wait for it to hit 220 degrees C
Unhook the black filament guides from the top of the extruder and load the filaments by feeding it through the stepstruder hole until the extruder motor hook onto it
A fine string of plastic will start to collect on the build platform, press 'M' when the color is right (some residual ABS might be present) and remove the plastic
Now, it is time to print a complete model, from the menu pick a model from the included SD card (not any starting with acc_* just yet)
Congratulations, the preliminary calibration of the Replicator is done!
Software setup
The Replicator can be controlled both from the on-board MakerBot user controls and the ReplicatorG printer software. Models can be loaded via USB or from the SD card. To prepare a SDL model, use ReplicatorG to create the necessary Gcode bot instructions file and the actual .s3g MakerBot processing file.
The steps below can also be found on the official Replicator software page.
Download the latest build of the open source ReplicatorG software, including the drivers for Windows
Perform the installation and setup Python (2.7.3) if necessary
From the Machine -> Machine Type (Driver) menu pick Replicator single or dual
Pick the correct serial port from Machine -> Connection (Serial Port)
Open the Control Panel to get to know the Jog, LED, temperature, stepper functionality of the bot
Open a SDL file from the File menu and scale, rotate or move the model to put it flat center on the build platform using the Move buttons
Hit Generate Gcode and then Build or put the file on an SD card, to print the model!
Printing settings
These are my 'go to' printer settings for the Replicator 1:
Extruder temperature: 235C
Speeds:
First layer: 20mm/s
Floor surface fills: 20mm/s
Insets/first inner wall: 20mm/s
Outliners/outer wall: 20mm/s
Sparse roof surface fills: 45mm/s
Infill density: 20 to 80% - depending on strength requirement
Number of shells/walls: 2 to 3 - depending on strength requirement
Support material extruder: same as model color
Raft material extruder: same as model color
Raft margin: 5.0mm
Support: On when needed
Extra support: Off
Reset of the settings is just default from the Standard pre-configured settings profile.
Total war: warhammer ii - the warden & the paunch crack. The Warden & the Paunch is the latest Lords Pack for Total War: WARHAMMER II. Introducing two rival Legendary Lords from the world of Warhammer Fantasy Battles, each with their own factions, objectives, mechanics, units and playstyle, for use in both the Eye of the Vortex and Mortal Empires campaigns, and custom/multiplayer battles. Eltharion the Warden. Dour but beloved ruler. Eltharion the Grim is truly one of the greatest of all Ulthuan’s generals. His past exploits of driving attackers from the shores of Ulthuan, including the first legendary Waaagh! Of Grom himself, saw him elected as the Warden of Tor Yvresse, and in previous years he has taken his blade overseas to the Old World in an attempt to scour his arch. Hello people, I am looking for the Total War Warhammer 2 Warden and Paunch DLC torrent. I can't seem to find it anywhere and I can't find information if it is cracked or not.
There is now also an alternative firmware by Simplify 3D:
Maintenance and improvements
Add blue thread-lock to all grubscrews on all the axis to prevent them to fall out [2]
Use Triflow or similar PTFE lubricant to all metal-to-metal mechanical motion [3]
Replace the system/case fan with a large 80x80 mm fan to reduce noise
Add a adhesive label on the right side of the joy-pad to indicate the insertion point for the SD card
Remove the ABS residue from the drive gear regularly [4]
Fit side and top covers to prevent dust from settling on the extruder and internal components
Enable accelerated prints to increase the print speed and efficiency, see below
To avoid warping of the prints, use PVA wood glue diluted in water (1 part glue, 3/4 part glue) and apply a thin film on the build surface 30 seconds before the print begins
Accelerated prints
A new feature which appeared on community 3D printers early in 2012 was the ability to accelerated the printing process. What this means is that instead of linearly moving the position by instantaneously starting and stopping the motors, the travel speed is gradually increased and decreased. While this method is slower when using the same travel feedrate as before, it will be faster when increasing, or doubling, the travel feedrate. The bot will not shake and vibrate as violently and work smoothly. But make sure to use high resolution models/gcode.
Python Version Check
Cutting models
Sometimes you got a model which is too large for the build platform and need to slice it into smaller pieces. This is easily done using netfabb Basic.
netfabb basic - just click through (skip) all the registration
In the lower right corner, drag the sliders to the specific dimensions and hit execute cut, select each piece and right-click to save as STL (not ASCII).
Estimate part costs
To calculate how much it costs to print a part is quite easy since it is built into ReplicatorG [5][6].
In ReplicatorG, pick Gcode -> Edit Slicing Profiles and edit the main profile
Select the Analyze menu and then the Analyze menu item
Pick Statistics tab and then check Activate Statistic and Save Statistics, and enter the values for machine time and material cost
Now, save all and go back to the main screen, pick GCode and Generate to generate the new gcode for the model
When the process finishes, a summary will show the time estimate, cost estimate and expected filament mass
