Safety precautions when moving the BCN3D Sigma D25
General information
You should read and understand the following safety measures to avoid any potential risks (We strongly advise you to read this before using the 3D printer).
There are areas where extra care must be taken. Safety alert stickers have been affixed to certain parts of the machine to warn the user of potential hazards.
Legal notice:
BCN3D is exempt from any liability if the user does not follow the use and safety instructions.
Hazards
The following stickers have been affixed to the printer to warn users about hazardous areas of the machine, and actions that are not recommended as they will stop the machine from working properly.
- Supervise the printer while it is printing to make sure it is working properly.
- The spatula can be a dangerous tool that can cause injuries. Use it only to remove plastic residue after calibration assistant or a printing job.
- Handle the printing surface with care. Make sure it is not dropped or hit with anything as this could seriously damage it.

The printer is powered by mains voltage, which is hazardous when touched.
Always connect the BCN3D Sigma D25 to an electrical outlet according to the current legislation to prevent any electrical risk.
If you need to do any maintenance or modification to the BCN3D Sigma, it's very important to turn off and disconnect the printer to avoid short circuits over the electronics or any risk of electrocution.
Even if the printer is turned off, you will need to disconnect it from the power supply to perform changes in the inner components.
In case of an emergency, stop the machine immediately by pressing the switch, and disconnecting the power supply. This will prevent more damage to the printer. Check the printer visually and contactthe BCN3D support team by filling this form.
Warning! As with any other appliance, do not touch the terminals of the mains, the switch, or the power supply. There is a risk of electrocution.
Do not touch the hot parts (heated bed and hotends) as there is a potential risk of burns: The hotend can reach temperatures up to 290°C, while the heated bed can reach peak temperatures of 150°C.
When the printer ends the print job, wait 15 minutes before touching the printing surface, the printing platform, or the hotends.
Pay attention to the temperatures screen to know when the hotends or the heated bed are too hot to touch them.
If you must remove the printing surface when it and the hotends are hot, stop any process, make sure that the printing heads are over the purge tanks, and use heatproof gloves to remove the printing surface.
Do not put any object or part of the body between the moving parts of the printer when it is moving or about to start moving. Check that the moving parts are free of any obstacle before starting any work with the printer, in order to avoid damage to the motors, linear bearings, and rails.
If you need to move the build plate up, do not force its movement, as it could damage the printing platform and the mechanical parts of the BCN3D Sigma D25.
If the printer does a movement that results in a crash, turn off the printer and check if any component is damaged. Usually, these problems are caused by an endstop malfunction. You can try to change the endstop or check if the flat cable is properly connected, check these guides to get more information about this:

The printing materials are not innocuous and emit toxic fumes.
It's recommended to always print in large, well-ventilated spaces, use a protective mask, and do not breathe closer than 25 cm from the toolhead when printing.
Where to install the BCN3D Sigma D25
In order to ensure easy access to the printer during maintenance tasks or its normal use, install the BCN3D Sigma D25 with enough space between walls and other equipment.
The 3D printer will need a clearance of 100mm at the sides to get easier access to the power button and its side handles.
If you want to work with external spools it's recommended to provide a 700mm clearance at the back of the printer. If printing without external spools, leave a 200mm clearance to help with the filter ventilation
Install the printer on top of a solid table or workbench that supports at least 50kg (recommended 100kg) and that has at least a 20% more surface than the footprint of the printer in each direction (recommended 1000mm x 800mm).
Use the BCN3D Sigma D25 in an environment from 15 to 30ºC and relative humidity below 50% to avoid printing issues or damage to the electronics of the printer.
Safety precautions when moving the machine
To ensure the safe movement of the machine, follow the steps described below:
Warning! The printer is heavy, two people are necessary to perform this step. Make sure that the table where the printer is being installed, is close enough.
1. Turn off and disconnect the BCN3D Sigma D25.
2. Remove the printing surface.
3. Lean the printer backwards, hold it from the side handles with the help of a partner and grab from the front-bottom of the printer. Pick the Sigma up by carrying the weight from your legs, and not your back, to prevent injuries.
Warning! Be extra careful when placing the printer on its new location, make sure it is stable in place and no limbs are underneath before putting it down.
