! Move exceeds maximum extrusion

General Discussion
1

Basic Information:

Printer Model: Ender 3 V2
MCU / Printerboard: v4.2.2
klippy.log - my klippy.log is nothing but Stats lines every 1 second.

I Just setup installed the Creality Sprite Pro extruder and have been struggling to get it to print anything. I think I’ve made a mistake by using klipper, but I’m trying to figure it out.

My latest issue is trying to print the pressure advance square tower and am getting a failure I have no clue what to do with.

I have sliced the tower with Cura and sent it to fluidd to print and it starts to print and then fails within seconds with

// Moving filament tip 0.0mms
17:26:21 
// KAMP purge is using firmware retraction.
17:26:21 
// KAMP purge starting at 102.8045, 40.79 and purging 30.0mm of filament, requested flow rate is 12.0mm/s3.
17:26:30 
echo: Print Started
17:26:47 
// Move exceeds maximum extrusion (8.700mm^2 vs 5.000mm^2)
// See the 'max_extrude_cross_section' config option for details

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

You know, it would be a lot easier to help if you included your klippy.log.

It’s the file that is “nothing but Stats lines every 1 second.” but there’s other information there that’s required to understand what’s happening.

Please post you klippy.log.

You have over 500 lines of macros - where did you get them?

More importantly: how did you validate them?

The first thing you should do is delete all the Macros (with maybe the exception of CANCEL_PRINT, RESUME & PAUSE) and try to run your print job again.

From there, we can work through any problems that arise.

Hey there! I could use your help with my 3D printer issue. You seem quite knowledgeable. I don’t know how to DM you yet

Post it here on the Klipper Discourse Group.

I’m sure somebody can help you.

I have discovered the problem. It was painfully not obvious, but the START_PRINT macro was putting the printer in relative mode and the slicer was expecting absolute mode. Once I added another M82 at the bottom end of the START_PRINT macro, it started working…smh
