M80 and M81 Questions
This is not really a big deal, but here goes. First i used a relay like this one https://www.amazon.com/SunFounder-Channel-Optocoupler-Expansion-Raspberry/dp/B00E0NTPP4/ref=sr_1_4?ie=UTF8&qid=1514679892&sr=8-4&keywords=relay+2+module to control the power going into my power supply. I also dissembled a Samsung phone power supply and used it before the relay to get my 5.25Vdc. From the phone power supply i power both the relay and the DuetWifi. This is actually working great and my 5V is more stable now. Anyways I am adding GCodes to my start and end print to turn the printer on and off.
I added M80 to my start print. And G4 S200 before the M81 at the end of my end Gcode.
- Is there a better way to wait for cool down then the G4 S200 if i want to shut the printer power off afterwards?
- Is there anyway to disable the low vin voltage error message when using the M81 gCode.
1. In 1.20 firmware, M81 S1 will wait until all thermostatic fans have turned off before turning the power off. So if you have your hot end fan configured to be thermostatically controlled by the hot end temperature, this should do what you want.
2. Currently there isn't, but I will take a look at this.
ok and when i tried it the M80 did not seem to work from cura. It works when i manually enter it. maybe i need to add a pause after the command.
You will need a pause between the M80 command and any movement commands, to allow the PSU to start up and the firmware to initialise the stepper drivers.
