- | * The Trimsaw 2 uses 6 inch diamond blades to make fine cuts in metals, glass, ceramics and PCBs. Specific blades for each material are available and should be changed before cutting new material. A variety of fixtures and guides are available with custom fixtures available for specific jobs (contact Dave Bothman or a Workshop Wizard for custom tooling). Spinning up to 3000 RPM the bottom of the blade is submerged in coolant to lubricate and cool the blade while in the cut. A blade splash guard and plexiglass cover reduce the amount of lubricant thrown by the blade. | + | * The Trimsaw 2 uses 4, 5 or 6 inch diamond blades to make fine cuts in metals, glass, ceramics and PCBs.

- | More information | + | |
- | “Formlabs Resin Tank Information” through the Formlabs website. | + | |
- | - Remove the empty resin cartridge: | + | |
- | - Close the vent cap at the top right of the resin cartridge to prevent resin from spilling out once removed | + | |
- | - Hold the cartridge handle and lift to remove from the Form 2. Store the cartridge upright | + | |
- | - Insert | + | |
- | - Shake and rotate the new resin cartridge to ensure that the resin is mixed thoroughly. | + | |
- | - Align the cartridge with the opening at the back of the printer. Push down on the cartridge handle until the top of the cartridge is level with the printer. | + | |
- | - Press open the vent cap to ensure the resin tank can fill correctly | + | |

- | More information on the resin system and changing a cartridge can be found on the webpage | + | |
- | “Formlabs Resin Tank Information” through the Formlabs website. This includes videos and | + | |
- | animations. | + | |
- | - Remove the build platform - this prevents resin from dripping onto the glass | + | |
- | - Remove resin cartridge: | + | |
- | - Close the vent cap at the top right of the resin cartridge to prevent resin from spilling out once removed. | + | |
- | - Hold the cartridge handle and lift to remove | + | |
- | - Remove the resin tank | + | |
- | - Hold the front tabs of the resin tank | + | |
- | - Gently pull the front tabs of the resin tank to release the tank feet from the tank carrier. The Resin Tank LT wiper ejects during removal. | + | |
- | - Cover the resin tank and store on the left side of the fume hood | + | |
- | - Insert the resin tank for the resin that you plan to use | + | |
- | - Lift the Form 2 orange cover. Use the tank grips to hold the Resin Tank LT, with the wiper resting inside the tank. If the tank contains resin, cover the tank with the plastic lid to align the wiper and minimize the risk of spills during insertion. | + | |
- | - Align and insert the four small feet of the resin tank into the corresponding slots in the tank carrier on the printer. | + | |
- | - Hold the front tabs and carefully push the tank until the tank feet lock into the slots on the tank carrier. Check the touchscreen display to confirm that the Form 2 detects the tank. The Form 2 will only detect the tank when the tank is fully inserted. | + | |
- | - Lock the wiper blade | + | |
- | - Align and insert the wiper foot into the wiper mount. | + | |
- | - Push the wiper toward the tank. | + | |
- | - Ensure the wiper foot is securely locked into the wiper mount. | + | |
- | - Insert resin cartridge: | + | |
- | - Shake and rotate the new resin cartridge to ensure that the resin is mixed thoroughly. | + | |
- | - Remove the protective valve cover from the underside of the cartridge. Use the cover to protect the bite valve during storage. | + | |
- | - Align the cartridge with the opening at the back of the printer. Push down on the cartridge handle until the top of the cartridge is level with the printer. | + | |
- | - Press open the vent cap to ensure the resin tank can fill correctly. | + | |
- | - Replace build platform | + | |
- | - Make sure that all of the resin tanks are correctly labeled. | + | |

- | * Cleaning | + | * Blade Cleaning |
- | * Use the scraper from the finish kit to inspect | + | * Cutting blade can become loaded with material despite coolant |
- | * Check for the following issues that may lead to print failures or any excessive wear that requires replacing | + | * Using the Miter guide, load the silicon carbide dressing stick onto the saw and feed slowly into the spinning blade about two to three mm. \\ {{: |
- | * cured resin on the elastic layer | + | * Lubing threads |
- | * debris or failed prints | + | * The aluminum blade retaining nut is prone to cold welding |
- | * settled pigment on the elastic layer | + | * To prevent thread galling a small amount of silicone grease must be applied to the arbor prior to threading on the retaining nut. |
- | * punctures, cuts, or gouges | + | * Emptying coolant |
- | * excessive “clouding” or wear in the elastic layer | + | * When not in use for long periods, |
- | * Filtering Resin | + | * To prevent staff from having to clean this, if the TrimSaw is not in use for over a month it is advisable to drain the coolant tank |
- | * Use a filter | + | * Draining coolant can be done with the ball valve on the rear of the saw and should be emptied into a container for safe waste disposal. |
- | * Cleaning the tank window | + | * Rinse coolant tank twice with water after coolant has been emptied. Water can be disposed of directly into the sink |
- | * Never use IPA on the acrylic | + | * Leave Trimsaw open to allow complete evaporation |
- | * If dust, fingerprints, | + | * Filling coolant |
+ | * Fill the TrimSaw coolant | ||
+ | * Add 120 mL of Coolmist coolant concentrate | ||
