Hello! Yes I'm working with @Benoitone to switch to Happy hare as the default ERCF system in Klippain. In the meantime you can already use it like that:
install.sh -i
) and let it do its jobprinter.cfg
let only
[include ercf_hardware.cfg]
but remove the following lines:
[include client_macros.cfg]
[include ercf_software.cfg]
[include ercf_parameters.cfg]
ercf_hardware.cfg
file add to the top:
[gcode_macro _USER_VARIABLES]
variable_ercf_enabled: True
gcode:
[include ercf_software.cfg] [include ercf_parameters.cfg]
4. Then in your `overrides.cfg` file, add this specific macro needed for the START_PRINT:
[gcode_macro _DO_ERROR_ERCF_PAUSE] gcode: {% if printer.ercf.is_paused|int == 1 %} {action_raise_error("ERROR ERCF !!! UNLOCK ERCF FIRST and restart start_print macro.")} {% else %} {% if verbose %} RESPOND MSG="ERCF not paused" {% endif %} {% endif %}
5. Check in the `ercf_hardware.cfg` file the pins and change them according to your `mcu.cfg`
With this, everything should work correctly. Also, you can be "safe" as the files are set in the "Klippain way" and will not be deleted on update :)
Many thanks for your great work !!
There is an issue with this description, the Happy Hare will not boot up and throw a warning. The [save_variables]
section in the variables.cfg
points to apparently original ERCF variables. This is "incomplete" for Happy Hare as the option ercf_calib_clog_length = 8.0
is not set. this missing line errors out booting ERCF.
since the variables.cfg is included "after" the ercf_hardware.cfg
of the [save_variables]
section the HappyHare include is overwritten. (That took HOURS for me to find out :D )
Ho Yes, in ercf_software.cfg The first 2 lines must be commented like:
**#[save_variables]
So ercf use the default klippain variable file to save is variable which is defined at the end of klippain variable.cfg file(because only one save_variable file must be present.)
I don't know if it's necessary to add: ercf_calib_clog_length = 8.0 in klippain save_variables.cfg ???
Ho Yes, in ercf_software.cfg The first 2 lines must be commented like:
#[save_variables] #filename: /home/pi/printer_data/config/ercf_vars.cfg
So ercf use the default klippain variable file to save is variable which is defined at the end of klippain variable.cfg file(because only one save_variable file must be present.)
I don't know if it's necessary to add: ercf_calib_clog_length = 8.0 in klippain save_variables.cfg ???
yes, as i described, you need to add the clog length or Happy Hare WILL NOT boot/start.
I just try to remove ercf_calib_clog_length
from my save_variables.cfg
file and when i make the ercf calibration (ERCF_CALIBRATE_SINGLE TOOL=0 or ERCF_CALIBRATE) the ercf_calib_clog_length
line has been created...
This doesn't work with the macro when I have an ercf error... Not sure what the issue is yet
OK, i just test too and I think it's a change in ERCF Happy Hare....
I think it can work...
{% set verbose = printer["gcode_macro _USER_VARIABLES"].verbose %}
{% set INITIAL_TOOL = printer["gcode_macro START_PRINT"].initial_tool %}
{% set status_leds_enabled = printer["gcode_macro _USER_VARIABLES"].status_leds_enabled %}
{% if printer.ercf.enabled|int == 1 %}
{% if printer.ercf.tool|int != INITIAL_TOOL or printer.ercf.filament != "Loaded" %}
{% if status_leds_enabled %}
STATUS_LEDS COLOR="ERROR"
{% endif %}
{action_raise_error("ERROR in loading filament from ERCF !!! Check and restart the print.")}
{% else %}
{% if verbose %}
RESPOND MSG="T{INITIAL_TOOL} ready"
{% endif %}
{% endif %}
{% endif %}
Closing as Klippain v4 is merged and released :)
Hi Frix-x Are you planning to support ERCF Happy Hare please? https://github.com/moggieuk/ERCF-Software-V3
Thanks
