The MakerBot Replicator
The MakerBot Replicator's dual extruders and big heated build platform make it an incredibly versatile machine, but they can also make it a bit tricky. The troubleshooting guides and documentation in these pages will orient you and get you back on track if something should go wrong. If you need more help, reach out to us through email at [email protected].

I need help installing ReplicatorG!
I can’t figure out which is the right serial port for The Replicator.
Sometimes it can be difficult to tell which serial port you need to select, even if your drivers have been installed correctly. Here's a tip that should help:
Open ReplicatorG with The Replicator disconnected. Go to the Machine->Connection (Serial Port) menu and note the port numbers you see there. Now, plug in your Replicator , go back to the Machine->Connection (Serial Port) and choose the “Rescan serial ports” option. Have a look at the selections again -- if a different port has appeared, that will be the correct port for your Replicator. If you don’t see an additional port, make sure that you’ve successfully installed the driver.
I changed my toolhead offsets in ReplicatorG 40, but they haven't updated.
I'm using Linux and my model doesn't show up in ReplicatorG!
I installed MakerWare and now I can't connect my bot to ReplicatorG.
How to stop Conveyor when you do not have MakerWare open depends on what operating system you're using. On Windows computers, stop Conveyor through the Services application. On Macs, open up Terminal and enter "sudo launchctl unload /Library/LaunchDaemons/com.makerbot.conveyor.plist". On Linux computers the command is "sudo stop conveyor". If you need to restart Conveyor, you can do that from MakerWare's service menu.
Every time I try to print, ReplicatorG wants to regenerate my Gcode!
How do I make a model bigger or smaller?
You can also adjust the scale by manually changing the number in the field next to the "scale" button. Inputting a 2 will double the size of the model, while inputting 0.5 will halve it.
How do I change the heated build platform temperature?
It will be about fifteen lines down, and the entire line will look something like this:
M109 S100 T0 (set HBP temperature)The number after the S is the temperature -- just delete it and replace it with another number. For example, you might find that your ABS prints stick better at 110° C, or that your PLA prints go better if the heated build plate is only set to 40° or 50° C.
If you like your new build platform temperature so much that you want to use it all the time, you can edit the start.gcode file for your profile -- try going to the "Edit Slicing Profiles" window and clicking the "Locate" button. The start.gcode file is where the temperature settings come from, so once you edit it, everything you slice with that profile should show your new temperature.
I'm having trouble installing MakerWare.
I can't connect to my Replicator 2 through MakerWare.

How do I change filament colors or materials?
You can also load and unload filament manually using ReplicatorG. Just heat up the extruder you're working with to 225° C. Then set the speed for that extruder to about 3.0 rpm, and run the motor backwards to unload. 30 seconds should be enough time to get your filament out. Once that's done, just run the motor forward while pushing the filament in to load it up again.
If you're changing colors, you'll notice that you'll need to run the extruder for a few moments to clear out the old color. If you're changing materials, it can take even longer -- make sure that all the old material is extruded before you start a new print.
I can't get the filament guide tube off my Stepstruder!
I can't load the filament into The Replicator!
If you're having trouble, use some scissors to make a fresh cut at the end of the filament. Cut the filament at an angle -- a narrow tip will help with loading.
Then, grasp the filament firmly and push it right down into the middle of the hole on top of the Stepstruder. You might want to hold the filament with a pair of pliers, or something else that's grippier than your fingers. Make sure it's going straight down, not diagonally. You can't hurt your Replicator by pushing on the filament, so use as much force as necessary. Once you feel the filament start to go in, maintain pressure for another ten seconds or so.
I can't get the filament out of my Stepstruder!
If you've run the motor backwards and forwards a couple of times and it's still stuck, turn off the motor and use a pair of pliers to pull the filament free of the heated extruder.
My extruder stays heated after I load or unload filament.
There's no plastic coming out of the extruder!
The things I’m building won’t stick to the platform!
To clean it, use a lint-free rag with a bit of rubbing alcohol or acetone-based nail polish remover. Acetone from the hardware store works well, too, but make sure you read and follow all warnings on the container.
If that doesn’t do it, try loosening each knob on the bottom of the build platform by about a quarter turn to move the platform closer to the nozzle.
If you're still having trouble, you can always run the leveling script again, from Utilities->Level Build Plate. This time use a thinner piece of paper, or move the platform up until you feel the nozzles grip it a bit more. You might need to try this process a few times in order to get it just right.
Another trick that can help (for ABS plastic only) is to raise your build plate temperature. There are instructions for this further down on this page.
Keep in mind that you always have the option to print with a raft, which will make it easier to get your prints to stick to the platform.
My Dual Stepstruder's nozzles aren't aligned correctly!
My Dual Stepstruder's nozzles aren't the same height!
Help! My bot sounds like it's shaking itself to pieces!
Replicator Firmwares 5.5 and later have an acceleration option. You can turn it off and on through General Settings in your Replicator's onboard menus or through Onboard Preferences in MakerWare or ReplicatorG. If you are running non-accelerated firmware or have acceleration turned off, you should not print at speeds above 40 mm/s.
Firmwares from Replicator Firmware 7.0 use a new type of acceleration command, and should only build from .x3g files. Running an .s3g file on a bot running Firmware 7.0 or later is equivalent to temporarily turning off acceleration, and will result in loud, jerky motion.
I can't find my file on the SD card.
Your Replicator also can't read file names longer than 26 characters -- 30 characters if you count the file extension. Shorten the file name and try again.
My Stepstruder is stuck/making a weird grinding noise!
Why won't the small features on my model print right?
You'll find this setting in the Dimension plugin. It's right at the bottom, under Retraction Distance, which retracts a little bit of filament when you stop extruding so that you won't end up with extra little drips of plastic all over the place. Restart Extra Distance lets you change when it starts extruding again. A positive value will make it start a little bit early, but we've got it set to a slightly negative value, so it starts a tiny bit late. Most of the time this is good -- you're much less likely to get little blobs at the edge of your prints. But if a section of your print has a really tiny horizontal diameter, that tiny length you're subtracting could become a problem. If the value there is -0.2, change it to 0 and see what happens.
My PLA prints keep failing!
How do I update firmware on The Replicator?
You can also update your firmware through ReplicatorG by going to the Machine menu and selecting "Upload new firmware..."
