The most useless warning message ever?

o_lampe

Hi guys,
while I tried to get my CoreXYV running, I frequently ran M98 P"config.g" to see any faults.
One time I got a warning like " improper use of 'P' parameter" without further details. (don't remember the real words)
I opened config.g and highlighted all 'P' characters. There were 50+...
It's like finding a needle in the hay...

@o_lampe Time for the good old binary search. Try with only first half of config.g, if a match, first half of that; otherwise second half of original. Repeat until only one P remains (-:

(I searched the source code for "improper" but nothing comes up. A genuine replica of the error might help pin stuff down).

Which firmware version? Standalone or with SBC?

It's RRF3.3.b2 in standalone mode, Duet2WiFi
The error only appeared once, I had no chance to take a screenshot

Thanks. I too searched the code base for the word "improper", and it doesn't appear anywhere. So I think it must have been a different word.

All RRF error messages that report a problem interpreting a command also report which command (G- or M-code) it was processing at the time.

If you get a useless error message again, please take a screen shot.

Casting a wider net, I found something in Endstops/EndstopsManager.cpp in GCodeResult EndstopsManager::HandleM574. Maybe that helps (i.e., check your M574s).

Thanks. I found "Invalid use of P parameter" there, however if this message was produced then it should have been prefixed by "M574: ".

Might be, I had some endstop-warning, too. But not at the same time. IIRC it claimed some endstop was already in use. But in fact it wasn't.

No there was no hint of anything. No line number or G-code relation.

I just noticed, I had RRF3.3.b2 running, but DWC is still 3.2.
Could this lead to unexpected behaviour, like echos of previous reboots popping up
Will upgrade ASAP.
