ZMOD 1.7 and PURGE

[snkku]

Please fix in gcode bambufy.cfg
[gcode_macro START_PRINT]
gcode:
{% set ifs = printer['gcode_macro _IFS_VARS'] %}
{% set zclear = printer.save_variables.variables.clear|default("LINE_PURGE")|string %}
{% set extruder_temp = params.EXTRUDER_TEMP | default(255) | int %}

zclear - is old variable
clear - is new...

old variable has "DISABLED" string

on zmod 1.7 purging failed with "Unknown command DISABLED" and skip purge

another one bug, with KAMP Leveling on start Z-Offset is fine, when skip leveling, nozzle scratch on table...
if I set correct z-offset, next print without leveling is fine, but with leveling - print starts in air :D

[snkku]

I see that LINE_PURGE already was in issue, but z-offset is actual :)

[function3d]

Run the BED_CALIBRATE command, follow the instructions, and test again with and without LEVEL(KAMP); the correct z-offset is the one that works properly when using KAMP.

I don't see that problem; my z-offset is identical with KAMP and without KAMP on start

was done two times after updating... as asked plugin, what is your version of zmod?

[snkku]

and how about save last used type/color/ifs port of filament? if its a same, dont do cleaning between old/new filament on start... to many plastic used by this procedure...

[function3d]

what is your version of zmod?

Zmod 1.7.1-46

Can you be more specific?

Every time the printer starts printing, it purges the old filament, then cleans the nozzle by filament, so why does it purge if the filament is the same as that used in the previous print? It wastes a lot of plastic.
In ZMOD added check on last and current filament, if its a same, its not purge "OLD" filament

[function3d]

I'll look into it, but the only real condition is that the filament not be removed from the IFS; the type or color doesn't matter—what's important is that the port used for the next print be the same as the one last used for the previous print and that it hasn't been removed from the IFS.

Even so, the user may accidentally or intentionally distort that memory; that is why it is always purged now, to ensure that the print does not start out stained by the previous color.

these are the problems of the user if he has a bad memory and understanding that he is changing the filament from one to another. :D but normal people suffer from excessive consumption of plastic

in any case, during refueling and the nozzle cleaning procedure, the plastic is run through, later it is also run through in LINE_PURGE, this is essentially enough

[function3d]

this is essentially enough

But, once again, the reality is that this isn't always the case, and the “purge old filament” feature aims to guarantee it 100%.

In any case, you're being a little dramatic, but I'll take a look at it

[function3d]

v1.3.3: The feature that remembers the last filament used is a session memory; that is, the memory is lost when Klipper or the printer is restarted. This is because if Klipper restarts, Bambufy loses track of what the user is doing, the user could remove one filament and insert another while the printer is off. Therefore, the first print of the session will always purge the remaining filament from the previous print, and on the second print of the session, if the filament from the previous print is the same, the purge will be skipped.
