MAINTAINING YOUR LINUS Duplicator 4pro
We've made the LINUS Duplicator 4pro incredibly easy to take care of, but there are a couple of things you'll want to do from time to time to keep it running as smoothly as possible.
LUBRICATING THE THREADED ROD AND THE X-AXIS IDLER PULLEY
- 1.1
- 1.2
- 1.3
After about 50 hours of build time -- or if your Duplicator 4pro starts to squeak -- you should lubricate your threaded Z-axis rod and the X-axis idler pulley. Everything else is self-lubricating.
To lubricate the threaded rod and the idler pulley:
1. Find the PTFE-based grease we sent you with your Duplicator 4pro.
2. Grasp both sides of the build platform and move it to the bottom of the Duplicator 4pro.
3. Use a clean, lint-free rag (or your finger) to spread the PTFE-based grease onto as much of the threaded rod as you can reach. Make sure you get the grease inside of the threads themselves. 1.1
4. Grab both sides of the build platform and move it to the top of the Duplicator 4pro.
5. Use a clean, lint-free rag (or your finger) to spread the PTFE-based grease onto the lower part of the threaded rod. Make sure you get the grease inside of the threads themselves.
6. 1.2 Locate the X-axis idler pulley. If you are facing the front of the Duplicator 4pro, the idler pulley is at the top left side. The idler pulley is one of the pulleys that allow the rubber belt to move the extruder from left to right. The pulley at the other end of the belt is called the timing pulley and does not require lubrication.
7. Squeeze a small amount of the PTFE-based grease directly onto the exposed area of the dowel inside the idler pulley and manually move the pulley back and forth to spread the grease. 1.3
HOW TO UPDATE THE FIRMWARE VIA DUPLICATOR
Every once in a while we come out with a new version of the firmware for The Duplicator. Uploading the new firmware to your bot will ensure that your bot gets all the latest improvements and operates as smoothly as possible. The most recent firmware released for The Duplicator is version 7.0. To check what firmware your bot has now, go to the Info and Settings menu on your bot's LCD panel and select Version Number. If you don't see an Info and Setting menu, you can find Version Number under Utilities -- but we can tell you right now that you will need to upgrade.
Disconnect from ReplicatorG
To upgrade the firmware on your Duplicator, you're going to need to disconnect from ReplicatorG. 1.1
Once you've clicked 'disconnect' in RepG, go into uplicatorG's Machine menu, check Connection (Serial Port) and make a note of which port The Duplicator was connected to --- you'll need it later.
Select your new firmware
1.2 Now go back to RepG.Go into the Machine menu and choose "Upload new firmware…"
The next step is to select the machine you’re upgrading. 1.3 In the case of The Duplicator, you’ll want to choose ”Makerbot Replicator (Mightyboard).”
Now choose the newest version of the firmware. 1.4 This should be the one at the top.
1.5 Next, choose the correct serial port. This will be the one you noted earlier.
1.6 Finally, you'll see a button labelled "Upload." Do not press it yet.
Locate the Reset switch
1.7 The reset switch is on the back of your Duplicator, just to the right of the USB port. You'll probably also need something to press the button with -- most fingers won't fit.
Hit the upload button, press the reset button, and wait
Hit upload, wait a fraction of a second, and then press the reset button. 1.8 It will take a little while, but soon you should see a message telling you that your firmware has been updated successfully.
If your firmware does not update successfully, don't worry -- the timing can be really tricky because it will vary a lot from computer to computer. Try different timings, like pressing the reset switch just before you hit the upload button, or waiting a full second between hitting the upload button and pressing the reset switch. The process of figuring out exactly when to press each button can be frustrating, but you can't harm your bot by getting the timing wrong. And once you have it right, you'll know what works best with your computer and you'll have a head start next time.
Once you see the "Firmware update succeeded!" message, you're set! Go back to printing with your exciting new firmware.
APPLYING KAPTON TAPE
- 2.1
- 2.2
- 2.3
Over time, the Kapton tape on your build plate will show wear. Too many scratches and tears will make it difficult for prints to stick to the plate and you'll want to replace it with another sheet. Here's how you can do that:
1. Peel off the old sheet of Kapton tape and discard it.
2. Take out a new sheet of Kapton tape. Peel back about a quarter inch of the backing at one of the short sides of the sheet. 2.1
3. Lay the exposed strip of Kapton tape along one of the short sides of the build plate. Use your finger to smooth it down so that it adheres well to the build plate with no air bubbles between the tape and the plate. 2.2
4. Peel off the plastic backing bit by bit, using the tape applicator to smooth it down as you go. If you don't have the tape applicator at hand, use a credit card.
5. Smooth the tape down bit by bit until you've covered the entire plate. If there are still bubbles under the tape, lift the edge of the sheet that's nearest and use the tape applicator to smooth down the tape from the center out. 2.3
6. When the Kapton tape is applied as smoothly as possible, fold down or trim the edges of the sheet of tape.
