[Ho-whizzle]

Hi All,
I have successfull installed and setup KAMP on my Voron Trident 300 except the purge command wil not happen and skipped before printing.
Any sugguestion why this is happening and what it the cause?
I have attahced the printer and KAMP config files for you all.

Many thanks in advance.

Looks like you forgot to include it as part of your PRINT_START macro.

OMG, how silly of me.
So I need to add VORON_PURGE to the START_PRINT section?

I added VORON_PURGE to start but I get the below error

[Extruder] max_extrude_cross_section is insufficient for purge, please set it to 5 or greater. Purge skipped.

After adding the max extrude code I get the following error after bed mesh:

11:55

That would be because your START_PRINT macro also doesn't set the nozzle temp. It has to be up to printing temperature before you initiate the purge.

That makes sense but what do I need to add to start the heating up to the target temp before it start the print/purge?

I am so confused. I have spent many hours trying to following instructions from the error message but with no luck.
I have attached photo and printer config for you all.

If it helps, the configuration you need to do is for the communication between the slicer and Klipper.
Right now, the slicer isn't telling Klipper what to do, and/or Klipper isn't configured to use it.

There is a little bit more info here:

I have a

M109 S{params.EXTRUDER}

before my LINE_PURGE (perhaps required for a Tap, which cools down the extruder for the bed mesh cal.)
