What Robox Catalog Actually Is and How to Use It
Robox is a dual-extrusion FDM 3D printer made by the Italian company Farasec. The system is known for using sealed, keyed filament cartridges rather than standard 1kg spools. When people talk about the Robox Catalog, they're usually referring to the material database that comes with PrusaSlicer or OrcaSlicer profiles for the machine. This catalog contains preset printing parameters for every filament type Farasec officially supports — PLA, ABS, Nylon, PETG, TPU, HIPS, PVA, and their composite blends. The problem most people run into is that these presets don't always match your actual printer behavior. I spent a few months on and off with a Robox S and found that the default catalog temperatures were consistently 10-15°C too high for PLA, which caused stringing and oozing that no amount of retraction tuning could fix. The workaround was simple but tedious: print the calibration tower at 5-degree increments below the catalog recommendation and find your actual optimal range. Once I had that, I edited the profile directly in the slicer's material database rather than relying on the stock catalog values.
How to Access and Edit the Robox Catalog in Your Slicer
If you're using PrusaSlicer, go to Printer Settings and select your Robox profile. Under Materials, you'll see the preset list pulled from the catalog. Click into each material to adjust temperature, fan speed, retraction, and print speed. Save a copy under your own name so updates don't overwrite your changes. OrcaSlicer works similarly but gives you more granular control over cooling curves and pressure advance. I prefer OrcaSlicer for the Robox because it handles the printer's dual-extrusion switching better. The catalog presets are still a starting point, not a destination. Set your first layer temperature 10°C above the nozzle temperature for better bed adhesion with ABS and Nylon — that's something the catalog doesn't tell you.
Common Pitfalls with the Robox Material System
The sealed cartridge design is a feature and a limitation. You can only use Farasec-branded filament or third-party cartridges that match the physical keying. Third-party filaments sold in compatible cartridges tend to have looser tolerances, which means the catalog parameters become even less reliable. I've seen inconsistent flow rates with cheaper compatible cartridges that threw off dimension accuracy by up to 0.3mm on small features. Another issue is that the catalog doesn't account for nozzle wear. The Robox typically ships with a 0.4mm hardened steel nozzle, but after a few hundred hours the effective diameter grows. When that happens, the catalog's default flow rate multiplier of 1.0 starts producing undersized parts. I keep a dial caliper handy and measure my printed calibration cube sides monthly. If they're running small, I bump the flow rate up by 2-3% per layer height above 0.2mm. The dual-extrusion aspect also deserves attention. Support material like PVA sounds great on paper, but the catalog's PVA settings assume proper humidity control. If your PVA has absorbed moisture, the catalog's drying recommendations won't save it. I learned this the hard way when a print took six hours and the supports dissolved into sludge instead of washing out cleanly. The fix is drying PVA at 45°C for at least 6 hours before loading it, regardless of what the catalog says about ambient storage.

When the Robox Catalog Falls Short
The catalog is designed for standard prints at standard speeds. If you're doing anything unusual — high infill density for functional parts, very fast printing, or exotic material blends — the presets will mislead you. I once tried printing a dense (>80%) Nylon part using catalog settings and ended up with severe warping because the catalog assumes moderate infill and doesn't account for the sustained thermal load of dense prints. The solution was dropping the print speed to 30mm/s and increasing the chamber temperature by running the printer in an enclosed space, which the catalog doesn't address at all. For users who need more reliability out of the box, looking into Klipper-based workflows with input shaping calibrated for the Robox's motion system can help. The printer's core-X configuration benefits from precise vibration compensation that the stock firmware doesn't provide. This is outside the scope of the catalog but worth knowing if you plan to push the machine harder than intended. The catalog is a reference, not a bible. Print your own calibration objects, document what works, and build a personal material library. That's the only way to get consistent results over time.
