Frequently Asked Questions - REX II BRESSER
How do I level the build plate on the Bresser REX II?
Use the included paper method or auto-leveling feature (if available). The manual details step-by-step instructions. Ensure the nozzle is at a proper distance from the bed for good adhesion.
What type of filament can I use with the REX II?
The printer supports 1.75 mm filament, including PLA, ABS, PETG, and TPU. Adjust the nozzle and bed temperatures accordingly. PLA is recommended for beginners.
How do I load filament into the printer?
Preheat the nozzle to the filament's recommended temperature. Insert the filament into the extruder until it comes out of the nozzle. Use the 'Load Filament' option on the touchscreen.
The print is not sticking to the bed. What should I do?
Clean the build plate with isopropyl alcohol. Apply a thin layer of glue stick or use a heated bed. Adjust the first layer height and ensure the bed is level. Increase bed temperature by 5-10°C.
How do I replace the nozzle?
Heat the hotend to 230°C. Use the provided wrench to hold the heater block and unscrew the nozzle. Install the new nozzle and tighten gently. Let it cool before cleaning.
My print has stringing. How can I fix it?
Enable retraction in your slicer settings. Increase retraction distance (e.g., 5-6 mm) and speed (40-60 mm/s). Lower print temperature by 5-10°C and increase travel speed.
What should I do if the printer detects a clog?
Perform a 'cold pull' by heating the nozzle to 100-120°C, then pulling the filament out. Alternatively, use a cleaning filament. If persistent, disassemble the hotend to remove debris.
How do I update the firmware on the REX II?
Download the latest firmware from the Bresser support website. Copy the .bin file to an SD card, insert it into the printer, and navigate to Settings > Update Firmware. Do not power off during update.
Can I print with the printer connected via Wi-Fi?
Yes, if the optional Wi-Fi module is installed. Configure the network settings via the touchscreen. You can then send files wirelessly using compatible software like Cura or Repetier-Host.
The printer is making unusual noises. What could be wrong?
Check for loose belts, bearings, or screws. Lubricate the linear rods with PTFE oil. Ensure the filament spool rotates freely. If the noise persists, inspect the motor drivers for overheating.
