Hi, I encountered a similar situation, even though I tried replacing my Arduino board. However, I still get similar readings from T1 and Bed (0.5V) and 5V from T0. I will try your solution! I understand that you reconfigure Bed to A10 in pin_Ramps.h, correct? Thanks Bertholdby beastro - RAMPS Electronics
QuoteDust Go back to a bare mega and test out the pins A13, A14 and A15 use this basic tutorial All you need is to change the pin used in the code (and wire it to that pin) (you do need to open the serial monitor to see the output) Thanks!! I had checked A13-15 and the voltage is as I wrote above. I have ordered a new Arduino now to see whether that fixes it. Thanks again for the help! Bertby beastro - RAMPS Electronics
Hi, I am opening a new thread for this one to divide the issues. As explained in the thread Blinking LCD I get invalid output for the Bed and T1 sensors. I triple checked the board and even replaced the capacitor for the T1 output suspecting that the problem might lie there. However, the problem persists and what puzzles me most is that T0 returns perfect results. If I measure voltage between tby beastro - RAMPS Electronics
Quoteenif As for the "blinking" menu and the not working KILL and RESET: Are you sure that your EXP2 cable is not somehow rotated 180 degrees on one or the other side? Are the two 10-pin cables identical with regards to the position of the connector locks? There are different versions of cables, controllers and adapters, as to the position of the connector locks, so that a wrong 180 deg rotatiby beastro - RAMPS Electronics
QuoteDust Sounds like that ADC on the mega is damaged... Try moving the bed to T2 (change the pins numbers in pins_ramps.h and move the plug) ramps schematics lcd schematics are the same as these Hi, I tried that, but no change. You are referring to this, true? #define TEMP_0_PIN 13 // Analog Input 13 #define TEMP_1_PIN 15 // Analog Input 15 #define TEMP_BED_PIN 1by beastro - RAMPS Electronics
Hi, I am new to 3d printing and inherited an old selfmade printer with Arduino 2560 and Ramps 1.4. I updated the Marlin firmware to the latest stable version and more or less got everything running with the following exceptions: The LCD - RepRap Smart controller - is displaying Text correctly and shows the menus, but it is constantly alternating between the first menupoint and its contents (liby beastro - RAMPS Electronics
