[XL777]

What is the problem?

There is this W that appears in the gcode in terminal
T:102.95 /0.00 B:74.43 /80.00 @:0 B@:127 W:?

I recently upgraded from marlin 2.0 to 2.1, both bugfix versions
I just want to know what W stands for, as it never appeared when running marlin 2.0

What did you already try to solve it?

WRITE HERE
I researched on google for an explanation for W, but was unsuccessful

Have you tried running in safe mode?

WRITE HERE
No

Did running in safe mode solve the problem?

Hello @XL777 !

@XL777

OK, downloaded and unzipped, now what?

No, Download from OctoPrint and upload here (The complete zip-file).

Could be helpful to know what printer you use.

BTW:
The W is not in the Gcode, it's a report from the printer firmware.
As you already noted, it came with Marlin 2.1. Maybe the guys at Marlin know more.

My Printer is a TRONXY X5S CoreXY from 2018. The board has been replaced with a BTT SKR Pro V1.2

Thanks for the info. I will give marlin groups a go.

The W part of the temperature line becomes a countdown. When you tell the printer to heat up on a blocking command (eg. M109 or M190), as normal at the start of the print, it waits for the temperature to stabilise. This W number becomes a countdown when it is close to finishing as an estimate for how many seconds it is going to wait before confirming the temperature.

[PrintedWeezl]

Iirc that stands for wait.
This is the time the printer waits for the temperature to settle.

For example if you set the bed temperature with M190 it shows you a countdown once the temperature reached the target temperature - just to make sure it doesn't start to fluctuate again.
