+ | ====Setting up the Carbide for a Job: | ||
+ | The Carbide router uses fun sized ER11 collets to hold tools from 1 mm to 7 mm but typically uses tools with a 1/8 inch shank. | ||
+ | **Changing tools:** | ||
+ | - Turn the router off and using an acid brush remove metal shavings and any dust from the tool head | ||
+ | - Using the 17 mm box wrench on the collet nut and the 12 mm open ended wrench on the spindle shaft flats loosen the collet and tool. | ||
+ | - Unscrewing the nut all the way allows the collet and tool to be removed from the spindle and changed out with a different tool of the same shank or with a different sized collet. | ||
+ | - Separating the collet from the collet nut can be done by pushing on the back end of the collet so that it becomes angled within the retaining collet nut and then can be pulled out. | ||
+ | - Before reinstalling the new collet and tool, wipe down the tool shank as well as the collet and spindle tapper. | ||
+ | **Homing and Zeroing the machine: | ||
+ | - With the tool installed, make sure the bed is empty and the cover is closed before turning on the machine | ||
+ | - Launch Carbide Motion on the Carbide computer | ||
+ | - Under " | ||
+ | - Select " | ||
+ | - Next while still under " | ||
+ | **Starting Job:** | ||
+ | - Load the desired G-code using the " | ||
+ | - Zero out the machine to match part zero | ||
+ | - Start Job | ||
- | ====Job Setup==== | + | ====Machine Limitations==== |
- | | + | * Each tool change |
- | -Load your STL file into the print software on the computer adjacent to the printer (Cura for Ultimaker, GrabCad Print for F270). | + | * Tool shank diameter is limited |
- | - Set Print Parameters: | + | * Max stepdown |
- | - Position the part on the build tray in a way that is conducive to 3D printing (flat side down) | + | * Work area is limited to 8" x 8" x 4" x,y,z |
- | - Select appropriate layer or slice height (the more slices the higher the print resolution but the longer it takes to print) | + | |
- | - For Ultimaker: | + | |
- | - Select " | + | |
- | - Check appropriate filament and bed temperatures (should be set if using standard filament load out) | + | |
- | - Send job to Ultimaker using USB drive | + | |
- | - For F270: | + | |
- | - The F270 the printer will print a raft before printing the model. Make sure first layer is set to support material or removal will be incredibly difficult. | + | |
- | - Send job to F270 over Ethernet | + | |
- | - Record the material used and print time in the online log along with the other job information requested. The print log should be on the desktop or https:// | + | |
- | | + | |
- | - Ultimaker: | + | |
- | - Make sure print bed is clean | + | |
- | - F270: | + | |
- | - Make sure that there is enough room on an CLEAN build tray for your part, and that the build tray is secured in the printer with the locking arm horizontal. Build trays may be used until the entire build area has been printed on, but printed areas should ideally not be reused. | + | |
- | - Start the job at the printer | + | |
- | ====Part Removal and Cleaning==== | + | ====Choosing tools==== |
- | **Ultimaker** | + | Many tools are optimized |
- | * Remove part from print bed using a spatula or razor being careful not to cut yourself or scratch the build plate. Make sure no body part is in line with the tool should it slip or the part break free unexpectedly. | + | Feeds and speeds can be found {{: |
- | * If support was used, submerge print in warm water for several hours to dissolve PVA filament. (prints can warp if submerged in water for over 24 hours) \\ | + | |
- | **F270** | + | |
- | * Don gloves, face shield, and lab coat | + | |
- | * Carefully, slowly | + | |
- | * Place large parts directly in the tank, small parts may be put in the SS box and placed into the main basket. | + | |
- | * Carefully, slowly | + | |
- | * Set timer for 6 hours setting the temperature to 80 degrees C. | + | |
- | * After cleaning time has elapsed follow the instructions above for opening | + | |
- | * Rinse part in warm water | + | |
- | ---- | + | ====File Types==== |
+ | G-Code files will be posted with the file extension .nc whereas Carbide Create will post files with the file extension .egc. G-code files can be opened directly into a text editor if necessary to preview or edit the desired code. .egc is a propriety package for G-Code used by Carbide for some god forsaken reason, in order to preview the G-code directly it is first necessary to upload the file to Carbide motion before copying and pasting the code into a preferred text editor. | ||

====Safety Concerns==== | ====Safety Concerns==== | ||
- | * Both print heads and bed are heated during operation. Do not attempt to clean, remove, or adjust without allowing for adequate cool down time. | + | * Safety Glasses must be worn when machine is running |
- | * Keep hands clear of printer during operation. Pause print before | + | * The acrylic shield must be in place and lowered before starting a job |
- | | + | * The spindle must be completely stopped |
- | - Launch Cura version 4 (blue icon) | + | * After milling is completed, the work piece will have developed sharp burrs which must be removed with a hand file or sandpaper |
- | - From connected printers, select IW-Ultimaker3 | + | ====Safe Operating Procedures Review==== |
- | - Select File -> Open Files -> Open desired project (.STL file type) | + | - Design part using Solidworks or other CAD platform |
- | - Using task bar on the left hand side, position model as desired | + | - Using HSM Works or Carbide Create generate tool paths |
- | - From print settings, select slice height, infill percentage, | + | - Each different tool needs to be a separate job as only one tool can be loaded into the Carbide at a time |
- | - Support can be generated using ether nozzle, typically nozzle one holds build material with nozzle two printing with dissolvable support material. | + | |
- | - Setting can be fined tuned using the "Custom" | + | - Simulate the toolpaths to verify that the tool will not crash and is cutting in the desired |
- | - Within custom settings, nozzle and build plate temps can be adjusted (build plate temps should be based off of build material) | + | - Using the 17 and 11 mm wrenches loosen the collet nut to change out the tool or collet itself if switching shank diameter |
- | | + | - Home the machine and zero the tool using Carbide Motion under the "jog" |
- | - Connect thumb drive to printer -> select desired file -> select print\\ | + | - Upload the G-Code into Carbide Motion under " |
- | Note: Adjusting settings may lead to more (OR LESS) successful prints. Contact Workshop Wizard responsible for Ultimaker if print fails or knowledge of advanced settings is desired. | + | - Start program |
====Post Processing==== | ====Post Processing==== | ||
- | * If support was constructed from ABS carefully break away with pliers | + | * Use a file to debur the part |
- | | + | |
====Maintenance==== | ====Maintenance==== | ||
- | * Bed should be cleaned with IPA between prints | + | * Tools should be wiped clear of chips or coolant using an acid brush |
- | * Print heads and silicone head protector | + | * The router |
- | * Filament | + | * Once a month the router |
- | * Bed leveling | + | * Twice a year the router |
- | * Print cores should be swapped | + | |
