RRF 3.5B2 Error: No bed heater has been configured for slot 0

[jp.douarvil 0]

Hello all,

I use RRF 3.5B2 on Duet 3 in standalone mode on a cartesian FFF machine. I used to reserve the heater slot 0~9 for the extruder heaters and 10 for the bed. In my case, this way of allocating the heater number makes the difference between extruders and bed heater very clear for the users.

The below configuration worked smoothly on RRF 3.4

; Bed heater
M308 S10 P... Y...	; configure bed temperature sensor
M950 H10 C... T10 	; create bed heater
M140 H10		; map temp sensor to heater
;M140 H10 P0		; same as above
M143 H10 S...		; set bed temperature limit
M307 H10 R... K... D... E... S1.00 B0	; heater tuning parameters

; Extruder 0 heater
M308 S0 P... Y...	; configure E0 temperature sensor
M950 H0 C... T0		; create nozzle heater
M143 P0 H0 S...		; set heater temperature limit
M307 H0 R... K... D... E... S1.00 B0 V...	; heater tuning parameters
M570 H0 P10 T15	; configure heater fault detection

; Extruder 1 heater
M308 S1 P... Y...	; configure E1 temperature sensor
M950 H1 C... T1		; create nozzle heater
M143 P1 H1 S...		; set heater temperature limit
M307 H1 R... K... D... E... S1.00 B0 V...	; heater tuning parameters
M570 H1 P10 T15	; configure heater fault detection

...

The same configuration still works (M140 behavior hasn't changed) on the 3.5B2 but the bed heater does not appears properly on the dashboard, as you can see below.

The dashboard temperature command does not work as expected:

• bed heater is not recognized by the dashboard (shows heater #-1)
  -> temperatures set up using the M140 SXXX RYYY commands are not being reflected on the corresponding active/standby controls of the dashboard
  -> dashboard's bed heater controls are unresponsive (can't turn ON/OFF/Standby, can't set up the temperature using the dashboard)

On the other hand replacing the line 4 with M140 H10 with M140 P10 H10 will solve the dashboard control issue. But then, everytime I need to setup the bed temperature through GCODE, I have to remember to indicate the slot number (M140 P10 SXXX RYYY) to avoid triggering an Error: No bed heater has been configured for slot 0 error.
This new behavior appears to needlessly complicate user's experience without obvious benefit. Plus, depending on the slicer used, the P10 parameter can be quite annoying to robustly implement.

Is that a bug or is there a practical reason why the DWC's behavior changed in the way described above?

Thank you in advance for your help.

Is your DWC up to date as well?

@Phaedrux Hello,

According to the info in Settings > General I am currently using the version Duet Web Control 3.5.0-beta.2. It is the version delivered with RRF Beta2 I took from there:
https://github.com/Duet3D/RepRapFirmware/releases/tag/3.5.0beta2
I haven't tried the 3.5.0-b2+ yet, should I?

Prior to that, when DWC was working as expected, I was using the version Duet Web Control 3.4.2.

[Phaedrux]

Can you share the full config.g?
Also please send M122 and M98 P"config.g" and copy paste the results here.

edit: attached config.g file is erroneous, this post may be ignored.

@Phaedrux Hello,

Attached is a "minimal" configuration exhibiting the issue.
config.g

And below the extract of the eventlog in debug mode following the >execution of an M122 and M98 P"config.g".

@jp-douarvil-0 This is the bed settings from your attached config.g:

M308 S10 P"temp0" Y"pt1000" ;Y"thermistor" T100000 B4092 ; configure sensor 0 as thermistor on pin temp0
M950 H10 C"out0" T0                           ; create bed heater output on out0 and map it to sensor 0

You created sensor 10 with M308 S10 ..., but are referring to sensor 0 with M950 H10 ... T0. That's why you get the message with M98 P"config.g":

2023-03-27 17:51:58 [warn] Warning: Sensor number 0 has not been defined

Change the M950 line to T10.

This error:

2023-03-27 17:51:58 [warn] Warning: M918: Command is not supported

Is because you have M918 P1 E4 F2000000 ; configure direct-connect display in your config.g. 12864 displays are not supported on MB6HC.

@droftarts Hello,

Thank you for the feedback.

I profusely apologize for posting an erroneous config.g file.

The issue doesn't actually go away after correcting it.

Let me share the corrected config.g and the corresponding eventlog after:

• execution of M122
• execution of M98 P"config.g"
• set the temperature to 70C via the dashboard --> error
• set the temperature to 60C via a test print file BedHeaterTest.gcode containing only the command M140 S60 P10 --> error
• set the temperature via M140 S50 --> no error but the set temperature (50C) is not reflected on the dashboard as show on the capture below

config.g

Thank you very much for your help.

@jp-douarvil-0 Thanks for reporting this, I think there is something wrong with bed and chamber control in DWC 3.5-b2. I'm going to fix this in 3.5-b3.

[droftarts]

@jp-douarvil-0 Okay, I am pretty sure this is a bug in DWC 3.5beta2, and @chrishamm is looking at it.

It seems the bed heater controls in DWC are referring to the bed heater 'slot' (or 'index') number (6HC supports up to 12 heated bed 'slots') but using the 'heater' number. The M140 command in config.g sets up which heater is the bed heater, with P0 (bed heater index 0) being the default. Yours M140 is M140 H10, which is the same as M140 P0 H10, or 'bed heater slot 0 is heater 10'. However, DWC 3.5beta2 shows bed heater slot 10 (using the heater number, not the slot number, which doesn't exist, and when you click the 'Heater' it sends M140 P10 S60. That is why you get this error message when you click on bed heater controls in DWC, and using the same Gcode in your test file:

Error: M140: No bed heater has been configured for slot 10

I think you can work around this if you set the bed heater slot to the same as the bed heater number. In config.g, change M140 H10 to H140 P10 H10. Your BedHeaterTest.gcode will also work then. (EDIT: I realise this is what you said in your first post!)

In DWC 3.5beta2, there is also a new setting in Settings > Machine-Specific to group heater control. For beds this is 'Single bed control'. If you enable this, M140 commands from DWC are sent without the P parameter, which should also work, as this sends commands without the P parameter, eg M140 S50, like you send from the console.

This then causes the final problem, the Heater 10 fault. This is because you have not tuned the bed heater; your M307 for the bed heater is still the default. You should be able to tune the heater; see https://docs.duet3d.com/en/How_to_guides/Commissioning#h-7-tune-heaters

EDIT: Any time M140 is sent without P parameter, it defaults to P0. So if you want to control it with the slicer without adding the P parameter, and with DWC, leave it in config.g as M140 H10 and enable single bed control, which should allow you to select heater slot 0 in DWC. Alternatively, set the bed heater up as Heater 0.

@droftarts , @chrishamm Hello,

The single bed control tip allows for controling the bed temperature via the dashboard at least, I can live with that .

Thank you very much for the explanations.

On the heater fault, its OK . I hadn't even connected the heater to the board as it was just a "unit test" built for the purpose of diagnosing the specific dashboard control issue.

@jp-douarvil-0 one of the perils of being a beta-tester! But thanks for pointing this out, we appreciate the feedback. We also found a couple of other related bugs; active and standby temps not showing if set by Gcode commands and same issue with chambers. It does work correctly if you revert to DWC 3.4.5, but there may be other issues running that with the beta firmware.

Unless you need specific features of the beta version, running the release version may be better for you, though we appreciate the feedback.

Ian
