Error: thermal runaway... Now both extruders unresponsive

Postby pearson222 » Mon Jun 25, 2018 5:14 pm

My N2 Plus Dual was preheating for a print and I was at the computer finishing up slicing the file. I uploaded the gcode to the printer and went over to the printer to begin the print when I noticed that the touchscreen said "Error: thermal runaway ..." I powered the printer down and let it sit for 10 min. I powered it back on and now neither extruder will preheat. I checked over all connections and nothing is disconnected or loose. Any ideas on where to start troubleshooting? This machine has had so many faulty parts since I received it that I am going to contact Raise3D about getting a replacement unit.

Sounds like a broken flex cable?

Anyone from Raise3D want to chime in? The printer is 100% unusable right now.

The extruders came back online the next day. I started a 12 hour print and about 5 hours in the nozzle stopped heating. There were no errors it just kept going like it was still printing. That resulted in a massive jam in the throat tube and extruded gears. It wasn't noticed until arriving the next morning. I found that moving the ribbon cable around a bit will reestablish connection with the heater cartridge and begin heating. The connector for the ribbon cable is fully plugged in and held very secure with the white adhesive from the factory. The ribbon cable has never been touched or had any stress on it at all and the board has always been securely fastened to gantry.

Can I submit one ticket for all of the issues? The printer is unusable as it’s hardware components are failing left and right. The majority of my time with the printer is spent troubleshooting issues. Frankly it has become an embarrassment to me, as I personally recommended these Raise3D N2 Plus’s to our company. When we began looking into expanding our printer lineup I persuaded them to go with Raise3D. I have one N2 down with at least a faulty ribbon cable. The other with severe under extrusion that can not be remedied by even a 200% extrusion multiplier- yet during the nozzle priming before the print and during filament loading it extrudes perfectly.


Besides the faulty ribbon cable, here are some other issues with the printer.

1. Heated bed came with warped corners & edges making it impossible to true the bed.
2. Severe under extrusion that is unaffected by slicer extrusion settings. Nozzle priming and manual/jog extrusions are normal.
3. Printer chooses what Gcode it executes and what it disregards. Some settings are adhered to - others not.
4. Main board housing arrived with the board & fan covered in dust. The fan is much louder than the other N2.
5. Numerous panel edges and seams are jagged and rough like they were ground by hand.
6. The z axis motors are 5X louder than the other N2 Plus.
7. Massive layer shifting on 1 out of 20 prints
8. Printer originally had a defective touchscreen module that prevented wifi functionality.

This printer has been a nightmare to work with since the day of delivery. My other N2 shares some of the same issues but seems like a Stratasys in comparison. We had to name the printers in order to identify them on the network and it took less than a month to earn its name: “B-Squad”. I understand that this might not be the place to have these issues addressed but I feel totally disheartened and am a total loss of what to do. With a massive job coming up that will require many printed elements, I don’t know how we are going to pull it off. Any guidance on where to go from here would be very much appreciated.

The fact that nobody from Raise3D has responded reflects my experience with support over the past year.

Hi Vicky- I already have a support ticket open (#3358). The only solution that has been offered is that I contact sales to purchase a new ribbon cable. Any help would be very appreciated. Thank you.

If the technicians figure out you have a defective ribbon cable, it is better to stop using the printer until the issue getting fixed. Or wrong temperature feedback may cause overheating.

The ribbon cable is broken. If I touch it during preheating it will turn off all heating. I need this printer up and running asap. How do I get a new ribbon cable?

Check with the support team whether your printer is still under warranty or not first. They will help figure out a way for you to get the parts.
