M555 does not work in config.g

[JuKu]

This is not really a help request, but FYI. (Is there an issue list for RRF3 somewhere?). Anyway, I have "M555 P6" as the last line in my config.g; it does not work. When I send it from USB, it works as expected.

FIRMWARE_NAME: RepRapFirmware for Duet 3 v0.6 FIRMWARE_VERSION: 3.0beta10 ELECTRONICS: Duet 3 version v0.6 FIRMWARE_DATE: 2019-09-12b1

Could it be a line end thing? Try putting a harmless command after the M555 in config.g??

[JuKu]

Not that.

Hi,

Did you try as the first line?

@JuKu The text may be sent to the bit bucket like the error messages that you can't see unless you run config.g after bootup.

In RRF3 the M555 setting is on a per-input basis. The beta build of RRF3 defaults to Marlin compatibility for the USB input channel. Do you need something different?

@dc42 Thank you for the explanation. As I said, this was not a help request, I brought it up in case there is a problem. For me, it is fine as it is, as I’m controlling the Duet from my own software. I need the nanoDLP compatibility, because in my application, I need to know when the machine has stopped. But since it is my software, there is no problem to send the command at startup.

Perhaps we should add a parameter to M555 to specify which channel it should be applied to, so that it can be used in config.g.
