Second Hotend Missing From Touchscreen

3 comments

 

Currently stuck on step 14 of this guide. The second hotend does not display AT ALL (see below).

 

Something's missing here...

 

There’s a blank gap where the second hotend should be, so it seems at least that the firmware uploaded correctly (about screen pictured below):

 

 

arduino configuration screen with firmware succesfully uploaded for referrence

 

I have double and triple checked the hotend heater cable connections, thermistor cable connection, and the hotend fan cables for the second hotend. Everything is connected as it should be according to the guide. The fans on both hotends are receiving power seeing as they do both spin up upon powering on the unit, so it doesn't seem that the problem is pertaining to the fan power leads. Additionally, I also checked for any physical irregularities in the wires, and they all seem fine.

 

PLEASE HELP.

I believe the software for the touchscreen dual extrudes is not yet released, nor is the Marlin files. I’m in same boat...

The instructions of the dual hotend have been updated now and new software is available as well.

Looks like the software update they put out last night must have done the trick because after re-downloading the updated marlin firmware and touchscreen firmware and re-applying both the second hotend is now showing up as advertised. Thanks for the heads up, FG.

Update seems to have worked

    No Connection or lights when connecting to USB

    Hi, I am attempting to complete Stage 10 Step 7. When I connect the control board to the computer USB port, I don't get any lights and the port doesn't show up in Arduino. I have tried 2 different computers, I have also tried connecting directly with the blue cable into the control board, rather than through the extension cable. With the same result. No lights showing. Directly connected and no lights. If anyone has any ideas I would appreciate trying them.

    Missing temp readings and heat on extruders and bed

    I am building the Proforge 2S with dual extruders and the heated bed upgrade and at stage 10, step 15 (https://makertech-3d.dozuki.com/Guide/Stage+10+-+Programming/15?lang=en) i see all 3 icons(heated bed, and both extruders) but only Extruder 2 shows the correct ambient temprature. Extruder 1 shows -15c and the heated bed show 166. To verify that the thermistors are working i tried to connect each and every one of them to the Extruder 2 pinout on the board and they all show their respective ambient tempratures, confirming that the thermistors work individually. However no matter what thermistor i connect to the other 2 connectors on the controller, i get no other reading. Do i have to enable something in the arduino code to enable the other ports on the controller? Someone suggested to swap the polarization of the sensors, but this left me with the same result. Additionally preheating the bed or any of the extruders does not change their temprature (using my fingers to feel if they get warm). I measured the powersupply and see good voltages. Has anyone else ran into this?

    Dead servo

    Look like I've got a dead servo. Tests failed on DSE Stage 07 - Switching Arm and Z-Offset I'll arrange for a replacement.
