Feature: Enable/Disable maintenance timers

[llambion72]

I think that it could be interesting to count print hours or not if you are printing certain material.
For example,
If you have a hepa filter, you need to know print hours to replace hepa filter but if you are printing PLA filament, filters are stopped and those hours shouldn't be added to filter counter. However, if you are printing ASA or ABS, hours should be added to counter.

Hi @llambion72 ,

That is an interesting idea. Just to confirm, you want to be able to specify if a certain maintenance is manually counted, with a parameter:

[maintain hepafilter]
...
always_active: false

And then, you can use commands at the start and end of a print to start and stop the counting:

# Print Start
{% if material == "ABS" or material == "ASA" %}
  START_MAINTENANCE NAME=hepafilter
{% endif %}

# Print End
END_MAINTENANCE NAME=hepafilter

[llambion72]

I have this config in my voron,

[maintain the_filter_hepa]
label: The filter hepa
trigger: print_time
threshold: 600
message: replace hepa filter

If you print something allways count print time. If you want to print a PLA piece...

Print Start

{% if material == "PLA" %}
DISABLE_MAINTENANCE NAME=the_filter_hepa
{% endif %}

Print End

ENABLE_MAINTENANCE NAME=the_filter_hepa

Another idea could be insert exceptions in config

[maintain the_filter_hepa]
label: The filter hepa
trigger: print_time
exceptions: PLA
threshold: 600
message: replace hepa filter

exceptions could be catched as parameter from slicer. I allways pass type of filament, temperature and others as slicer parameter

I'll start working on the first method, with ENABLE_ and DISABLE_MAINTENANCE.

Hi @llambion72 ,

A beta for this feature is now available in the dev branch.

Installation

cd ~/KlipperMaintenance
git checkout dev
git pull
sh install.sh
sudo service klipper restart

---

Configuration (OPTIONAL)

Optionally, to make it disabled on start, add the disabled parameter to your specific maintenance:

[maintain hepafilter]
...
disabled: true

---

Commands

To enable/disable (pause/resume) maintenance reminders, use the ENABLE_MAINTENANCE and DISABLE_MAINTENANCE. Examples:

# assuming disabled: true for hepafilter

# Example PRINT_START logic

{% if material == "ABS" or material == "ASA" %}
# turn on HEPA filter
ENABLE_MAINTENANCE NAME=hepafilter
{% endif %}

# Example PRINT_END logic

DISABLE_MAINTENANCE NAME=hepafilter



# Alternatively,  you can insert this in your FILTER_ON macro

ENABLE_MAINTENANCE NAME=hepafilter

# and this in your FILTER_OFF macro

DISABLE_MAINTENANCE NAME=hepafilter

I've started to check it. I need to print some part in ASA and PLA. I'll give you some feedback on the next days.

[llambion72]

I'll try two prints and I think that there are something wrong... Disable messages is shown for them but elapsed time for three elements is counted instead they are disabled

It's this my printer console log at this morning printing a part

I'll look into this...

[3DCoded]

Hmm... I'm unable to reproduce the issue on my end. If I disable maintenance, wait a while, and then enable it again, it keeps the same time.

[llambion72]

I config print_time as the trigger.
In my case, I disabled maintenance only for the filters (two items), I printed for two hours and when i enable it again there are two hours discounted for all devices, disabled and enabled items.

My config file,

[maintain]
interval: 600 # optional, time (in seconds) between checking if maintenance needs to be done (default is 60)

On the print start macro,

{% else %}

    M118 {FILAMENT_TYPE}, desactivo el contador de los filtros (disable filter maintenance)
    DISABLE_MAINTENANCE NAME=nevermore
    DISABLE_MAINTENANCE NAME=the_filters
    DISABLE_MAINTENANCE NAME=the_filter_hepa

{% endif %}

On the print end macro,

{% if FILAMENT_TYPE == "ABS" or FILAMENT_TYPE == "ASA" %}

    #Clean VOCs
    M118 Limpiando VOCs durante 10 minutos (VOCs cleaning)

Hi @llambion72 ,

Does enable/disable work if you do trigger: time (not print_time)?

[llambion72]

Hi @llambion72 ,

Does enable/disable work if you do trigger: time (not print_time)?

What events add usage time with the 'time' parameter? Just by leaving it on or do I have to do something?

[3DCoded]

Hi @llambion72 ,

For the time trigger, it's just arbritary time, independent of whether or not a print is running. It's a workaround, but you should be able to set disabled: true in the config, then use ENABLE_MAINTENANCE at print start, and DISABLE_MAINTENANCE at print end.

[llambion72]

Ok, I'll try it

[llambion72]

I've changed rails trigger to time instead print_time and I've printed a couple of parts.

Rails hours value, Rails: 249.46h changed to Rails: -1712.48h after 17h printing.

11:01:22
// Rails: -1712.48h remaining
11:01:22
// Belts: 1881.77h remaining
11:01:22
// nevermore: 58.17h remaining
11:01:22
// The filter left & Right: 68.17h remaining
11:01:22
// The hepa filter: 597.17h remaining
11:01:22
// Extruder maintenance: 185.9m remaining
11:01:22
// Machine: 4881.77h remaining
