During the use of your BCN3D Sigma, it's possible that you stumble on an Error screen from time to time. In this article, we will explain all the Error screens that can appear and how you can solve them to get back to printing as usual:

 

 

Heating Failed errors

 

Thermal Runaway errors

 

Max Temperature triggered errors

 

Min Temperature triggered errors

 

Firmware flashing error

 

 

 

 

Machine Configuration errors

 

 

 

Emergency Stop error

   

 

Unknown Error

   

Heating Failed errors

A "Heating Failed" error screen will appear when the unit is trying to heat up a certain heater (in this case the hotends or the hotbed), and it doesn't warm them up at the optimal speed. 

There are many causes on why this happens, it is most commonly an issue with the connection of the heaters (hotend flat cables or hotbed cable) or a defective component.

 

Heating failed on Left/Right Hotend

 

Check 1. When this type of error shoots up, it means the hotends are not well connected, defective, or there's not enough power to heat them completely. To locate the actual issue, first, check that the flat cable connections are well:

Check 2. If the error still shoots up, swap the hotends from side to side, if the error then shoots on the other side, the issue is located in the hotend, which will have to be replaced. This article will help you in the process:

Check 3. If the issue persists on the same head, try swapping the extruder boards from one side to the other, if the error shoots on the other head after this change, the extruder board will have to be swapped out for a new one.

Check 4. If the issue still persists on the same head, it's possible that the hotend flat cable is damaged. It will have to be replaced as well.

Check 5. If this error shoots on both hotends and the hotbed, and you're not able to move the printing platform, it's possible that the mainboard fuse has blown due to a shortcircuit. In this case, you'll have to replace it.

Heating Failed on Hotbed

 

This can happen due to a failure in the Hotbed power supply or in the hotbed itself. If keeps happening after resetting the printer, get in contact with the BCN3D Support Team.

Thermal Runaway errors

 

 

 

These errors shoot when the printer triggers the Thermal Runaway Protection feature. This protects your printer against a thermistor malfunction that could cause damage to the printer. 

 

If a thermistor fails, it will read a lower temperature than the actual. The system will turn the heater on forever, burning up the filament and anything else around, this Thermal Runaway Protection turns off the heater once it detects a thermistor malfunction. 

 

In this case, this is related to the Thermistor itself, you'll have to replace the component that the display indicates. If this error shoots in the hotbed, get in contact with our BCN3D Support Team.

Max Temperature triggered errors

This error occurs when the printer reads a temperature above the machine's maximum temperatures:

 

BCN3D Sigma Series max Hotend temperature: 300ºC

BCN3D Sigma Series max Hotbed temperature: 80ºC

 

If your unit reads a value above the maximum temperatures and the issue does not solve when resetting the controller, this is a sign that the heater thermistor, the printer's electronics, or the mainboard is malfunctioning. 

Max temperature triggered on Left/Right hotend

 

 

When this type of error shoots up, it means the hotend thermistors are defective, or the electronics of the printer deliver too much power to the hotend . To locate the actual issue, follow these steps:

 

Check 1. Swap the hotends from side to side, if the error then shoots on the other side, the issue is located in the hotend, which will have to be replaced. This article will help you in the process:

Check 2. If the issue persists on the same head, try swapping the extruder boards from one side to the other. If the error shoots on the other head after this change, the extruder board will have to be swapped out for a new one.

Check 3. If this error shoots on both hotends and the hotbed, and you're not able to move the printing platform, it's possible that the mainboard fuse has blown due to a shortcircuit. In this case, you'll have to replace it.

Max temperature triggered on Hotbed

 

This can happen due to a failure in the Hotbed power supply or in the hotbed itself. If this happens, get in contact with the BCN3D Support Team.

Min Temperature triggered errors

This error occurs when the printer reads a temperature of 0ºC or below. If your unit reads a value below the minimum temperatures and the issue does not solve when resetting the controller, this is a sign that the affected controlled is not connected, or the heater thermistor, the printer's electronics or the mainboard are malfunctioning. 

Min temperature triggered on Left/Right hotend

 

 

When this type of error shoots up, it means the printer is not detecting any thermistor, or the electronics of the printer do not deliver any power to the hotend . To locate the actual issue, follow these steps:

 

Check 1. Check that the hotends are well connected and the flat cable connections are good.

Check 2. Swap the hotends from side to side, if the error then shoots on the other side, the issue is located in the hotend, which will have to be replaced. This article will help you in the process:

Check 3. If the issue persists on the same head, try swapping the extruder boards from one side to the other. If the error shoots on the other head after this change, the extruder board will have to be swapped out for a new one.

Check 4. If this error shoots on both hotends and the hotbed, and you're not able to move the printing platform, it's possible that the mainboard fuse has blown due to a shortcircuit. In this case, you'll have to replace it.

Min temperature triggered on Hotbed

 

Check that the connection between the hotbed and mainboard is correct, this can also happen due to a failure in the Hotbed power supply or in the hotbed itself. If this keeps happening and the connection looks good, get in contact with the BCN3D Support Team.

Firmware flashing error

 

This happens when the firmware is not properly loaded in the mainboard. The most possible cause is an irregular BCN3D Cloud connection, make sure your Wi-Fi signal is strong enough to be detected by the printer. If this keeps happening, try loading the firmware this way:

Machine Configuration errors

 

This usually happens when starting to use your brand-new BCN3D Sigma, in most cases this is fixed by simply reconfiguring the printer.

 

However, if the following message appears, get in contact with BCN3D's Support team:

Emergency Stop error

 

This message appears when the printer is not able to detect any endstop or one of these is malfunctioning. This article will help you locate and solve this issue.

Unknown Error

 

This error is shot by default if the error is not related to none of the above. Reset the printer and, if this doesn't solve the issue, contact with the BCN3D's Support Team.
