M500 writes file with empty M307 values

gtj0

Not sure if this is a RRF or DSF issue but running M500 results in a file with no data for the M307 parameters

; Heater model parameters
M307 H A C D S B0
M307 H A C D S B0
; Workplace coordinates

Here's what M307 reported:

M307 H0
Heater 0 model: gain 356.6, time constant 852.6, dead time 0.6, max PWM 1.00, calibration voltage 24.5, mode PID
Computed PID parameters for setpoint change: P711.3, I31.449, D298.7
Computed PID parameters for load change: P711.3, I169.374, D298.7

M307 H1
Heater 1 model: gain 717.2, time constant 306.5, dead time 5.1, max PWM 1.00, calibration voltage 23.8, mode PID
Computed PID parameters for setpoint change: P15.0, I0.379, D53.4
Computed PID parameters for load change: P15.0, I0.927, D53.4

Update. It looks like there no code in DuetControlServer to populate the heater model which is why M500 writes empty values.

It has...

heaterObj.Current = response.temps.current[heater];
heaterObj.Max = response.tempLimit;
heaterObj.Name = response.temps.names[heater];
heaterObj.Sensor = heater;
heaterObj.State = (HeaterState)response.temps.state[heater];

but no heaterObj.Model.

@gtj0 yep still on the todo list!

Yeah. I just figured out how to change a topic to a question so it would have the unsolved/solved tags

This is solved in DSF 1.3.0
