Hi David,
When do you expect to want payment for the 2 nozzle upgrade?

Hi,
I am awaiting delivery of one of your dual boards, but will be unable to upgrade to dual nozzles for a while. Can I at least make a start and use the dual board for my single nozzle set-up or does the board expect there to be two nozzles?
Alan

Hi Paul, two thoughts:
- If you specify G10 with the S and R parameters in the config file, the firmware will set the active and standby temperatures right after you turn on your machine. So it's no surprise the heaters turn on right away and the fan starts spinning
- IIRC the Duex4 shares its AGND line with the normal GND, which is quite noisy, so you may be better off hacking an extra connector onto the Duet as dc42 did. I believe I saw a few photos on his blog a while ago showing his custom thermistor header glued to the Duet PCB.

dc42
PS - if the voltage drop on the 3.3V rail on the X4 is a constant value, it could be compensated for by connecting a high value resistor between the +5V pin on the X4 expansion connector and the positive thermistor pin (which is the blue wire AFAIR). This would be a less intrusive modification. It wouldn't address the noise issue, but might be enough to correct the head 2 temperature reading and prevent the fan from turning on when the hot end is cold, given the filtering that I already implemented.

What value of resistor would you recommend?

Hi Dave. If the 4th dual nozzle board is still unallocated, may I request it?
