Initial Thoughts - H2D

[partferret]

There was an old P1/A1 firmware change that set the bed temp to first_layer right away after download. Did that get carried over to the H2D?

If not, then you can modify the machine start gcode to automate it

Reduce bed electrical consumption

Had similar issues, based on my observation, the bed doesn’t require a lot of power to maintain its temperature, it will only consume the maximum power during the heat-up process. So what I did was to limit its heat-up time by telling the printer to heat a 5C first and wait 15s before proceeding to the next 5C. If the printer is just heating a 5C, it won’t use 100% power due to the PID controller. This method seems to work for me. Below are my changes to the Machine start G-code Original Code …
