I was looking at the Analog pins and extension header, [reprap.org], and the Ardunio Mega pins 89-94 don't seem to be going to the correct analog pin header as per schematic [reprap.org] all but pin 90 seem to be incorrect. 89 PK0 ( ADC8/PCINT16 ) Analog pin 8 Analog-Ext 1 90 PF7 ( ADC7/PCINT15 ) Analog pin 7 Thermistor 3, Analog-Ext 2 91 PF6 ( ADC6/PCINT14 ) Analog pin 6 Analog-Ext 3 92 PF5 ( ADC5/TMS ) Analog pin 5 Analog-Ext 4 93 PF4 ( ADC4/TMK ) Analog pin 4 Analog-Ext 5 94 PF3 ( ADC3 ) Analog pin 3 Analog-Ext 6 Shouldn't Analog-Ext Pins 1 and 2 be VCC and GND ? https://reprap.org/forum/read.php?1,331714,331714#msg-331714 Mon, 14 Sep 2026 10:53:01 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,331714,331714#msg-331714 https://reprap.org/forum/read.php?1,331714,331714#msg-331714 reprap.org], and the Ardunio Mega pins 89-94 don't seem to be going to the correct analog pin header as per schematic [reprap.org]

all but pin 90 seem to be incorrect.

89 PK0 ( ADC8/PCINT16 ) Analog pin 8 Analog-Ext 1
90 PF7 ( ADC7/PCINT15 ) Analog pin 7 Thermistor 3, Analog-Ext 2
91 PF6 ( ADC6/PCINT14 ) Analog pin 6 Analog-Ext 3
92 PF5 ( ADC5/TMS ) Analog pin 5 Analog-Ext 4
93 PF4 ( ADC4/TMK ) Analog pin 4 Analog-Ext 5
94 PF3 ( ADC3 ) Analog pin 3 Analog-Ext 6

Shouldn't Analog-Ext Pins 1 and 2 be VCC and GND ?]]> Hiram General Sat, 29 Mar 2014 10:16:45 -0400
