Using Robox for the first time:
- Install software from here first https://www.cel-uk.com/shop/automaker/ it is updated quite often so the software in the box is most likely outdated.
- After unpacking, removing internal packaging and checking all items are present and correct, plug the printer in while the software is running. It will ask to update the firmware, you should always allow this so firmware and software are matched.
It is best to stick with one filament type, this reduces contamination of materials and just keeps things simpler, avoiding blockages due to degraded or mixed materials.
- Snip any bent or deformed filament from the start of the reel.
- Poke this filament into the feed path, there are 2 inlets, use the top one.
- Keep pushing it in, you will hear a motor start but keep pushing until you feel the filament being dragged from your fingers, the print head will also move to the right hand side.
- Once loaded you should “purge”, you will find the button to do this at the bottom of the main status screen. This heats the bed and nozzles and flushes out the previous material in the head. All heads are tested with so there will be a coloured material in the nozzles already. Follow the instructions on the screen. If it asks for a purge temperature you should choose one which is suitable for both the new and the old material. 230°C is fairly safe for most but some require a higher temperature to make them liquid enough.
It will take around 3 mins to heat the bed, as the bed gets near temperature the nozzles will heat taking around 1 min.
The head will move around probing the bed, setting and testing heights. Then the nozzles will draw lines of filament across the bed surface.
You can try a print once this process is finished.
You may need to calibrate nozzle height and nozzle opening, leave nozzle alignment until you have done more prints. The calibrations are step by step and fairly simple, be sure to read each step as the calibrations set up various numbers which are used in the print process. The button to start calibration is in the status screen at the bottom.
Some models will load into AutoMaker in the wrong orientation, there is a button called “lay flat” click this and then click the surface you want to be the bottom. There are controls to change scale and orientation. If your model was designed in inches you will need to scale it 2540% to get the correct size.
Use the default settings for a few prints, try each one, draft, normal, fine. Small details may be missing on draft, if details are smaller than the nozzle used they may be ignored during a print, this mainly effects the XY plane, details on the side of items are built using Z and are less effected. There is more information about this limitation which is true of all FFF printers available online.
Support structures are generated automatically if the box is ticked, if you aren’t sure just tick the box. You will soon see how support works and is generated.
Fill density can be kept around or below 30% in most cases, parts are still very strong. Lower fill density uses less material and is much faster, there is also less shrinkage.
ThermoSurface is the print surface of a standard Robox. It should be slightly rough (see next post re. sanding) which can be done using some 320 or 400 grit sandpaper, it may require this when new and whenever parts are peeling up on their edges or not sticking at all. Be sure to remove the bed surface before sanding and clean it very well with water and then IPA when dry. Regular cleaning with IPA is the only other care required. NEVER put masking tape, hairspray or any other reprap recommended print surface on the Robox print surface, none of these come close to the bonding potential of ThermoSurface.
Remove the mini purge from the tip wipe blade before each print. Clear small bits of debris from inside the build chamber regularly. You can slide the black plastic cover under the front door out to the front of Robox and tip the whole unit forward to clear debris which falls into the space below the bed.
After 100 hours of printing you may need to put a drop of the included lubricant on some rails but never the top horizontal rail. Take care not to get any on the print surface. There are further directions for this online.
Purge any time a material is changed, purging when the same material is used but a different colour is up to the user. Check the head is tight occasionally, the screw is behind the head and is tightened by hand.
This may get debris build up with some materials. Ask the support team for advice.
