2/10/2024 0 Comments Raise3d grid type support![]() ![]() I checked resistance between all the terminals to ensure they are completely disconnected and isolated from the circuitry on the Raise board - so I'm just using the terminal blocks to clamp the thermocouple wires together at the print head. I cut all the traces around the terminal blocks on the Raise daughterboard where the thermocouples used to connect. Hope that will get the job A few nights back I moved the thermocouple daughterboard down to the Duet2 Wifi board. I'll cut through the traces coming off those terminals to ensure the circuits on the board don't cause trouble. I'll use the thermocouple terminals on that to connect the thermocouples to the long leads. I don't have good connectors for the thermocouples, but I plan to mount the Raise daughterboard back in its original location. Sucks that I have to cut all the wiring loose from the print head and route it all again - thought I was done with this project. Found some shielded thermocouple wire on eBay that will let me move the thermocouple board down to the Duet board. I have the N2+ wired up the same way, but due to the additional height it needs more ribbon cable, and neither of the extruder thermocouples is reporting reliably. ![]() Did have one thermocouple that "went bad" - replacing the thermocouple resolved the issue, but I now think it was a communication issue. I guess I've been lucky with the N2 with about 6ft of ribbon cable. I have since learned that having a long extension cable from the Duet to the Thermocouple daughterboard is a bad idea. I also have the 12x12x24" N2+ - that will get the Duet treatment soon. Heaters and fans for the heated enclosure. The print head has additional fans for improved cold-end cooling and controllable print cooling.Īll the 3D printed parts in the photos have been replaced with new prints since the upgrade since I'm getting much better results from the machine with the Duet board. It has the bondtech dual extruder upgrade. The bed has been modified to to get the clips out of the build area and make it easier to use alternative bed materials. The machine has also been modified to have a heated enclosure on an independent temperature controller. I didn't have a better option in the parts bin. I kept the factory daughterboard on the print head, but I'm only using it for the heater terminal blocks. I mounted the thermocouple board on the print head so I didn't need to run thermocouple wire down to the control board. The PT100 board is for the bed sensor - could not use the stock sensor. I'm using both PT100 and thermocouple daughterboards. ![]() I recently upgraded my Raise3D N2 to a Duet 2 Wifi. ![]()
