Frequently asked questions

The CraftBot printer should be lubricated at least once after every 50 hours of use or every 6 months.

Tools needed for lubrication:

  • PTFE based spray lubricant or grease
  • 2 separate lint-free rags or thicker stronger paper towels
  • personal protection such as gloves and safety glasses/goggles
  • lighting to see the interior of the CraftBot correctly (lamp)
  1. Move the build plate and the extruder to "Home" position - see chapter 13 for more information.
  2. Once the extruder and bed are in the home position, turn the CraftBot printer off and unplug it from the electrical outlet.
  3. If you look beneath the build plate you will see three rods that run vertically in which the build platform moves up and down on. The two outside rods are smooth and the center rod is threaded. These three rods are known as the "Z-axis rods".
  4. Place a folded paper towel or a lint-free rag behind the center rod. This rag is used to protect other areas of the printer from any overspray that may occur.
  5. LUBRICATE ONLY THE PARTS RECOMMENDED IN THIS MANUAL!
  6. Spray the threaded Z-axis rod at a relatively close distance to reduce overspray. Make sure the lubricant reaches the inside of every thread (if using grease, spread with hand wearing gloves).
  7. Make sure not to overlubricate, spray only the minimum required amount!
  8. Do not spray the other two rods directly! Spray the towels and wipe it onto the rods.
  9. Remove the rag from the CraftBot interior.
  10. Plug in and power up CraftBot and move the build plate to the lowest point ("Axes" menu, home position and then go to the directional menu and press the Z down arrow until the bed reaches the lowest point).
  11. Turn the CraftBot printer off and unplug it from the electrical outlet.
  12. Place a second clean rag on top of the heated build plate to protect the components and Kapton from any overspray.
  13. Repeat the process for the top side of the Z-axis rods the same as you performed on the bottom side: protective rag behind threaded rod, spray, wipe excess lubricant on other two outside rods.
  14. Power up the CraftBot once again and raise the build plate back up to the highest position (set the X, Y and Z to home position).
  15. Turn the CraftBot printer off and unplug it from the electrical outlet.
  16. Wipe any excess lubricant off from the bottom side of the Z-axis rods.
  17. Power up your CraftBot once again and move the build plate back to the lowest point.
  18. Turn the CraftBot printer off and unplug it from the electrical outlet.
  19. Wipe any excess lubricant off from the top side of the Z-axis rods.
  20. Power up the CraftBot once again and raise the build plate back up to the highest position.
  21. Turn the CraftBot printer off and unplug it from the electrical outlet. The motors will now disengage so that you can move the extruder freely by hand.
Use an oiled rag to lubricate the X and Y axis rods. Do not spray from above! Move the extruder back and forth by hand to both extremes of the axes. When the extruder moves absolutely smoothly you are finished.

The number one inconvenience that you will run across when 3D printing is clogging of the extruder. But we have good news for you! This problem can be easily avoided by following a few simple rules of "3D printing etiquette". First, always wait until the extruder and heated build plate are fully heated to their maximum intended print value before inserting the filament. Inserting the filament at a lower temperature is just asking for a clog. When unloading or changing the filament: always heat up all the way first and then "extrude" for 5 seconds and immediately "reverse" aiding the filament retrieval by pulling a little bit on the filament end going into the extruder with your hand. If the extruder is clogged, clean out the passage way of the extruder. You can use one of the small hex wrenches coming with your CraftBot to do so. Heat up to 250°C while the extruder is empty and push any excess filament out by plunging the hex wrench down into the passage way; make sure to do adequately but not in a violent way which would damage the machine, and always take precautions because the extruder is very hot! It is especially important to clean out as much old filament leftover between using different filaments, as the different characteristics of the filaments' properties (even printing the same material in a different color) can cause clogs from inconsistencies. For example: you must heat up to 250°C to clear out any extra ABS before using PLA. Clogging is the most common problem in every 3D printer and cannot be prevented 100%, but if you follow these simple steps you will prevent 95% of occurrences. If you still cannot clear the passage with just this method, you may want to move onto the next method by following these next steps to actually remove the nozzle itself.

To clean out the extruder properly by removing the nozzle you will need to remove the nozzle while heated up to 250°C using both a 7mm and 11mm wrench for the two nuts located on the nozzle itself and the channel end to the top side of the extruder. Make sure to use an over mitt to protect yourself from burns. You will also need to disconnect the fan assembly and remove the entire piece by unfastening two bolts connecting it to the top of the extruder. Most importantly, make sure to hold the red rubber part stationary at all times so that you do not damage the wires running into it, you can use a wrench to do so. Please make sure that none of the wires are disconnected. The removed nozzle can be unclogged with a pin or replaced with a new one.

From time to time you may want to look into updating your firmware (the special software which provides control over the functions of your CraftBot). New versions are released periodically on our website, and you can find them bundled with our CraftWare slicer software here: https://www.craftunique.com/craftware For a step-by-step process on how to download our newest firmware (a.k.a. "CraftPrint"), please check the following video: https://www.youtube.com/watch?v=S0k99lYU9SA

From time-to-time you may encounter a traffic jam scenario when attempting to upload this new firmware; in some cases your CraftBot screen will go completely blank and even seem to be "non-functional"... but do not worry! This situation can be easily remedied by following these easy steps to "erase" and "reset" both your PCB and LCD. Make sure that the machine is turned off and disconnected from the electrical outlet. To access the PCB first, remove the back plate of your CraftBot by unscrewing the bolts securing it to the main frame using one of the hex wrenches provided in the set which came with your CraftBot. Be sure to take notice of the wires connecting the back plate fans to the interior; you should be able to easily disconnect these by reaching inside as soon as the plate first comes lose. After the plate is off, you will see the PCB board. Before you do anything here, you will need to also prepare the LCD for erase and reset following these steps: Take a look at your LCD display located at the middle top front of the CraftBot 3D printer. You will need to get around to the back of the LCD to erase and reset. For the best access to this part of the board you may want to remove the lid of your CraftBot by loosening the bolts using once again, your trusty hex wrench included with your CraftBot. Make sure to watch out for the LED wire connecting the lid to the rest of the CraftBot! You can disconnect this wire by reaching in and unplugging it from the back of the LCD first. Now that the lid has been removed, you may or may not need to remove the back protective plate of your LCD panel, depending on the version of LCD that you own. The latest version of the LCD has the "erase" and "reset" buttons located on the side, so removal of the plate is not necessary. For everybody else, use your hex wrench to loosen the bolts and remove the plate. Be careful not to drop the bolts on damage the belts. Inside you will see the two buttons, "erase" and "reset". Now you can plug in and power up your CraftBot. At this point the screen should still be blank and your CraftBot should still be unresponsive. For the LCD, push both buttons at the same time and release. For the PCB, use two pieces of filament to insert into the "erase" and "reset" ports at the same time (the same effect as pushing a button). Now you can turn the CraftBot off and wait at least 5 seconds before turning back on. From this point proceed to the firmware update mentioned previously and after uploading you should have a 100% operational CraftBot 3D printer!

Build plate Kapton sheets get worn out in time, or can be damaged by the nozzle due to incorrect leveling. Reapplying a new Kapton sheet is essential to maximize print qualities if the old one has issues.

  1. To reapply a new Kapton sheet, take the build plate out of the machine and remove the old sheet by striping it off of the aluminum plate.
  2. Clean the surface of the aluminum plate with acetone.
  3. Remove the protective sheet on the new Kapton in order to apply the sticky side, apply some window cleaning liquid onto the plate and the sticky side of the sheet to help you to correctly position the sheet.
  4. Align the Kapton to the front side of the plate (the side where screws stick out) on the corner.
  5. Once the positioning is correct, squeeze out the liquid from between the plate and the sheet with a thin but solid object, like an unused credit card. Place the protective sheet (which was removed to open up the sticky part) on the building Kapton to prevent scratches and damages during application. Start from the center of the plate and move horizontally and vertically. Once all the liquid has been squeezed out and the sheet is applied properly, put the plate somewhere to dry. Allow the sticky part to rest for a day before using.
  6. Place back the building plate and fix its position with the two white screws.
  7. Level the building plate. (For detailed instructions see chapter 9 of the User's Manual).

If you are located in the EU as a private consumer (not a business) and you would like to purchase a CraftBot, you must pay the Hungarian VAT tax. If you are located outside of the EU (anywhere else in the world) you do not have to pay the VAT tax for the EU, although you may be subject to your own country's taxes or import fees. If you represent a business within the EU, please provide us with a legitimate VAT number or code and we will deduct the VAT cost from your purchase. If you purchase from our website you can conveniently enter this information during checkout.

Lead time can vary depending upon our demand and production at the time, but for the most part your printer will be sent out within the week of purchase/receiving payment. If there happens to be a delay in production, you should find the time estimate posted on our website in the product description and during the time of checkout for your purchase.

The great thing about the CraftBot 3D printer is that it is very user-friendly: you can easily adjust the print settings to compensate for different materials, and our very own made-from-scratch slicer program "CraftWare" allows you to compensate and modify the support for even the most difficult 3D prints (you can get great prints with even the most default of settings, but our method provides you, the user, with the platform to customize settings to achieve the optimal print for almost any different physical characteristic). With all this said, the types of material that you can use are near endless; it just takes the trial-and-error on the user�s end to find the optimal physical settings. For materials such as ABS or PLA, your best bet is to start with the default settings and go from there depending on the print. We have also gotten great results printing with other standard and more exotic filaments such as Nylon, HIPS, woodfill, bronzefill, flexible filament, PET, PET-G... the list goes on.

Please check this part of the manual: "Firmware update", and you should be happily on your way in no time! If you are looking for specific recommendations on how to optimize a specific print or fix a flaw in the print, sometimes the best place to go is to our forum located on our website. There is always a whole bunch of hardcore 3D printing geeks hanging out ready to talk anything-3D. Also you can find many answers in past forum posts.
