Start Macro

[Wardad5]

Hello,

I was wondering if anyone had a good macro for a start purge line? I have been working with mine and can't seem to get it to heat up, quad gantry level, then bed mesh all at the right temperatures. I have a Voron 2.4 with 350 mm sized bed. If anyone has a good one along with what you put into the slicer (super slicer) to get them to communicate well with each other I would be very grateful. Thanks!

@Penatr8tor pulled the prime blob/prime line routines from the ratrig klipper macros, the PRIME_BLOB macro produces a nice "Hersheys Kiss" type of blob.  Rather than duplicate the uploaded macro's file, here's a link to the post. Not being experienced with the 2.4 I couldn't really reliably comment on your heat soak, QGL, mesh issues

Here is some simple gcode adapted a little from the standard Prusa prime line. You can modify the X/Y coordinates as needed.

[gcode_macro _PRINT_START]
...
    M117 Priming ...
    G28
    G1 X2.0 Y8.0 F18000            ; go to edge of bed
    G1 Z0.2 F5000                      ; lower nozzle
    G92 E0.0                               ; reset extruder position
    G1 X50.0 E8.0 F1000.0          ; start intro line
    G1 X90.0 E9.0 F1000.0          ; finish thicker
    G92 E0.0
    M117 Printing ...                      ; display message

Like @smirk, I am at a loss with the 2.4 specifics like heat soak and QGL.

This is my start macro :

    M117 Heating Toolhead
    M104 S{params.TOOL_TEMP}
    M109 S{params.TOOL_TEMP}

### Start of the PRIME LINE ROUTINE ###########     
    M117 Prime Line ..........
    G92 E0.0            #reset extruder distance position
    G1 X10 Y10 Z0.3 F3000       #move to prime line position

    M117 Starting Print .......
    STATUS_PRINTING                                #LED Status Color

and supersclicer custom g-code:

M140 S0
PRINT_START tool_temp=[first_layer_temperature] bed_temp=[first_layer_bed_temperature]

Hope this helps

I put together a purge line similar to the Prusa one, but have recently switched over to the KAMP purge (along with adaptive bed mesh). I'm liking it better.

Klipper Adaptive Meshing and Purging

[Wardad5]

These are all great suggestions. I will try and fiddle with them when I get the chance. The Klipper adaptive meshing looks nice. I like efficiency (speed). Thank you

 

[Wardad5]

I spent some time last night and put the KAMP and the purge from that, along with the start macro they referenced. Worked great. Thanks for the suggestions!

[smirk]

@claudermilk After your recommendation I've been trying that KAMP seting (rather than getting on with my build). Wow! It's brilliant. I'm really pleased with the results and the great purge line (way better than the simple line of string that I had before). Ever day is a school day! Many thanks.

Another KAMP convert - Really easy to set up and works a treat.

It does (unless you forget to comment out your old purge line, then you get some interesting extras....)

This...

Will be the final addition to my TAP install.

FInal? That sounds very final definite......is that possible? A mod being finished?!

[Wardad5]

I had the KAMP set up and it worked well for a couple of prints, but now I just started a new print after updating klipper and such and it probed the whole bed? Any idea why that might be the case?

Make sure that the update has not disabled the object exclude stuff. Especially the line in the moonraker.conf file:

[file_manager]
enable_object_processing: True

Without object_processing being enabled it will definitely probe the entire bed.
