I am trying to use a solenoid instead of a proximity sensor to probe the bed, since the proximity sensor is heat sensitive and gives different results based on temp. The solenoid is connected to Pin5 and 2 on the PWM above the Mega chip.
I chanded the FW and when I send a M402 i only read 4.77v. Since my solenoid is 5v it is not enough to trigger it and I thought I should have 12v on that pin 5 anyway. Any ideas?
