Describe your issue:
Hey guys, Just wondering if someone could help me interpret the shaper calibrate graphs i have done on my SV06+? I have read through the klipper guides etc, but I’m not the brightest spark 
What i’m wondering is whether i should set my ‘max_accel’ to the lowest recommended setting? Which would be on the Y-Axis looking at the graphs.
i.e max recommended acceleration without too much smoothing for X-Axis is 7200mmSec^2, but the Y-Axis is only 2800mmSec^2.
So, Should i be setting my max_accel to 2800 in my printer.cfg?
It just seems a bit low tbh, I have been printing with max_accel at 7000 and have been getting pretty good quality prints.
Anyhow, any tips/pointers would be much appreciated.
Cheers.

Thinking about this further, i guess i should leave my max_accel in the printer config and just change Y-Axis accel in the slicer motion ability, correct?
Do the graphs look ok though? I’ve heard there should ideally be only one spike/peek…. Is this just a general rule?
Klipper does not allow per-axis acceleration limits, so even if you configure them in slicer, that won’t do anything. You should set your maximum acceleration limit (max_accel) to the lowest of the two axis, maybe with some safety margin (i.e. max_accel = 2800 or perhaps max_accel = 2500).

Oh right, that’s exactly the kind of answer i was looking for, thanks. I’ve been using 7000 max accel for about 2 years now lol. I gave up printing for about a year but decided to get back into it. I’d forgotten so much. I have minimal ringing tbh and have great quality prints.
So the machine ability acceleration settings in the slicer does nothing when using Klipper? Interesting.
Thanks for the info mate, much appreciated.
Acceleration settings from slicer that specify acceleration for different features (not different axes) will work for Klipper:
But for example a command M201 X7200 Y2700 from Marlin is not supported and will not do anything in Klipper.

Thanks, I know Marlin code will not work for Klipper, i was talking about the machine limits/Motion ability section under the printer settings within the slicer. I have lowered mine now, they were much higher before….. My thinking was that if i set the X-Axis to say 7000 and Y-Axis to the limit (2800) via these settings, the X-Axis would still be able to accelerate of those speeds wherever possible… But if as you say, Klipper disregards these settings, then it doesn’t really matter anyway.
Cheers.
