Remora 1.0.0_rc released for testing

Thanks. Are you going to post it here or git?

Run away can happen for a few reasons. Most common is hardware failure such as thermistor wire develops a break or comes lose/ separates from the device being heated.

Without any watch dog it will keep trying to heat until it destroys itself.
This would be best done at the lowest level that if the heater is not responding it would give up vs going forever.

Grbl boards use PWM for dc spindle control. So it would be good to have an option for PWM spindle as well as 0-5v and 0-10v if possable

Well most out boards I think use 0-3.3v pwm logic
In my config tool the voltage is up to the user I use an aftermarket board to convert pwm to analog 0-10v

Depends on what pin you use. I drive mine from a gpio pin not using one of the fan or heater outputs.

So the config tool right now just makes pwm. Maybe I should make that more clear.

Using the heaters for the pwm control is a problem in my setup as they are low side driven vs high.

The Remora thermistor module already has some basic protection for a broken / disconnected sensor. When disconnected the thermistor calculations output a negative number, which cannot be possible in real life. In this condition the logic then outputs a stupidly high 999degC which is also not possible. Any PID controller seeing this quickly sends the SP command to zero.

What about if the thermistor becomes separated from the object being heated?

I gave your config app a shot, very nice!!. for the trimac 2209 is there a way to add the stall guard home option.?
