Preheat the nozzle by selecting Temperature on the printer screen. Then select Preheat Small or Big Toolhead (depending on the toolhead). 2\. Push the silver tension lever all the way to the left. This will release toolhead's tension, allowing for filament to be removed from the toolhead.  3\. Remove the guide tube by pressing down on the black ring and pulling up on the tube. 4\. Pull on filament, and it should slide out easily. Feed it back up through the guide tube and respool it onto the roll. 5\. From the dehydrator, pull the filament from the guide tube until you can safely remove the filament spool from the dehydrator. Secure the loose filament end into the side of the spool. ![](https://www.help.protosthetics.com/hs-fs/hubfs/undefined.png?width=115&height=153&name=undefined.png) ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Apr-16-2026-09-33-35-5145-PM.png?width=129&height=151&name=image-png-Apr-16-2026-09-33-35-5145-PM.png)   ![a3](https://www.help.protosthetics.com/hs-fs/hubfs/a3.png?width=268&height=151&name=a3.png)   #### Note: Always have a firm grip on the loose filament end as you're removing it from the kiosk/dehydrator. Letting go of the loose filament end will result in tangled filament. ### Loading Filament Settings Follow the below chart to know **how to load filament for the type of product you're printing.** - Which type of filament to load - Which side toolhead to load filament onto - What temperature to load it at - How many clicks of tension it needs | Product Type | Filament Type | Extruder Nozzle | Loading Temp | Tension Clicks | | --- | --- | --- | --- | --- | | Check Socket | PETG | Extruder 1 (Right) | 260 | 1 Click | | Flexible Socket | TPU (Cheetah) | Extruder 1 (Right) | 260 | 2 Clicks | | Preparatory   Socket | PC Blend | Extruder 1 (Right) | 260 | 1 Click | | Articulated Ankle   Foot Orthotic | PC Blend (Left)   PETG (Right) | Extruder 0 (Left) Extruder 1 (Right) | 260 260 | 1 Click | | Functional Foot Orthotic | TPU (Cheetah) | Extruder 1 (Right) | 260 | 2 Clicks | | Accommodative Foot Orthotic | TPU (Varioshore) | Extruder 1 (Right) | 260 | 2 Clicks | **Note:** When loading Varioshore, be sure to reload the filament before every print, extruding 2 - 3 inches of filament. Only load filament if you intend to start the next print right away, as Varioshore does not start well cold. ### Loading Filament 1\. Insert the filament roll on the left or right side **according to the above chart.** 2\. Cut filament end at a 45 degree angle so it is **pointed at the end.**  3\. Feed the filament down into the guide tube **until it comes out the other side.** ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Apr-16-2026-09-42-42-5290-PM.png?width=300&height=398&name=image-png-Apr-16-2026-09-42-42-5290-PM.png) 4\. Click on the temperature button.  ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Sep-22-2026-03-36-31-3135-PM.png?width=570&height=266&name=image-png-Sep-22-2026-03-36-31-3135-PM.png)  5\. Select to Preheat the toolhead you are loading filament in. This automatically sets the temperature to 260.  ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Sep-22-2026-03-36-39-1868-PM.png?width=570&height=266&name=image-png-Sep-22-2026-03-36-39-1868-PM.png)  #### After the toolhead has heated up... 6\. With the tension set to 0 clicks (all the way left), **insert the filament into the top of the toolhead.** 7\. After filament is inserted, **set the tension to the appropriate click.**  8\. Insert the guide tube back into the top of the toolhead so it locks in place. ### Tension Clicks               **Left:** 0 clicks                      **Middle:**  1 Click                     **Right:**  2 Clicks ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Apr-16-2026-09-49-56-9976-PM.png?width=190&height=252&name=image-png-Apr-16-2026-09-49-56-9976-PM.png)![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Apr-16-2026-09-50-10-3242-PM.png?width=190&height=252&name=image-png-Apr-16-2026-09-50-10-3242-PM.png)![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Apr-16-2026-09-50-31-9645-PM.png?width=190&height=253&name=image-png-Apr-16-2026-09-50-31-9645-PM.png) 9\. Select the appropriate Extrude Toolhead button.  ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Sep-22-2026-04-06-23-2162-PM.png?width=570&height=266&name=image-png-Sep-22-2026-04-06-23-2162-PM.png)   10\. Click the Extrude Toolhead button as many times as needed for filament to begin extruding out the bottom side of the nozzle. If keeping the same filament type, extrude at least 4 inches of filament. If changing filament types, extrude at least 6 inches of filament that you are loading.   11\. Click the Cooldown button to cool the toolhead.   12\. Wipe the nozzle with the red maroon pad to prevent filament from caking.   #### Note: If the Filament isn't extruding, give the filament a brief tug. - If the filament pops out, flip the silver tension lever to the left (step 6), and push the filament a slight bit deeper than before. - Afterwards, flip the silver lever to the right and attempt to lightly pull the filament out. It should remain firmly within the toolhead.   #### Job's Done! **If you are printing a preparatory socket using PC Blend or an AFO using Nylon, please apply adhesive to the bed following this [guide](https://www.help.protosthetics.com/galileo/pc-blend-prep-socket-bed-adhesive?hsLang=en).** - [Account & General Information](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#main-content) - [Account & Permissions](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#account-permissions) - [Policies & Guarantees](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#policies-guarantees) - [Printer Returns](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#printer-returns) - [Scanning Options](https://www.help.protosthetics.com/galileo/scanning-options?hsLang=en#main-content) - [App & Hardware Setup](https://www.help.protosthetics.com/galileo/scanning-options?hsLang=en#app-hardware-setup) - [Scanning Best Practices](https://www.help.protosthetics.com/galileo/scanning-options?hsLang=en#scanning-best-practices) - [Ordering Process & FabOne Portal](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#main-content) - [Placing & Managing Orders](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#placing-managing-orders) - [Print Control](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#print-control) - [CFAB Options](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#cfab-options) - [Galileo Product Options](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#main-content) - [Prosthetic Products](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#prosthetic-products) - [Orthotic Products](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#orthotic-products) - [Customization & Fitting](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#customization-fitting) - [Filament & Printing FAQs](https://www.help.protosthetics.com/galileo/filament-printing-faqs?hsLang=en#main-content) - [Filament Loading & Handling](https://www.help.protosthetics.com/galileo/filament-printing-faqs?hsLang=en#filament-loading-handling) - [Preparing the Printer](https://www.help.protosthetics.com/galileo/filament-printing-faqs?hsLang=en#preparing-the-printer) - [Hardware Troubleshooting & Maintenance](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#main-content) - [General Tips & Tricks](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#general-tips-tricks) - [Connection Troubleshooting](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#connection-troubleshooting) - [Hardware Troubleshooting - Pro](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-troubleshooting-pro) - [Hardware Maintenance - Pro](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-maintenance-pro) - [Hardware Troubleshooting - Galileo O&P/Pro 2](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-troubleshooting-galileo-op-pro-2) - [Hardware Maintenance - Galileo O&P/Pro 2](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-maintenance-galileo-op-pro-2) [![ProtostheticsGalileo Logo-1](https://www.help.protosthetics.com/hubfs/ProtostheticsGalileo%20Logo-1.svg "ProtostheticsGalileo Logo-1")](http://protosthetics.com) 510 6th Ave N, Ste D, Fargo, ND 58102 USA [mailto:success@protosthetics.com](mailto:success@protosthetics.com) Copyright © 2026, Protosthetics
