Do we have to declare jerk somewhere in FW?
-
Hi.
Ender 5 Pro with BL Touch
Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.05.1 (2020-02-09b1)
WiFi Server Version: 1.23
Web Interface Version: 1.22.6I am watching this video as I learned that my printer's jerk & acceleration is not set correctly and therefore suffer from ringing, amongst other things. I was therefore advised to watch the video to test and set my printer's jerk & acceleration.
When I do M503 I do not see the M204 declared and also not that jerk is mentioned. How will I know if jerk is enabled on my printer? (I understand that RepRap and Marlin are not the same and use different G-code, but will love to know the RR code equivalent for Marlin.)
If there is another YouTube video explaining the same for Duet/Reprap, I will really appreciate it if you can point me to it.
Thanks for your help.

@deonholt M204 isn't for jerk. M205 is
M204: Set printing and travel accelerations
M205: Set max instantaneous speed change in mm/sec

duet GcodeThanks very much.
Interesting enough I have neither declared in my Firmware or config.g
I am very new to 3D printing and even newer to Duet/RR.Can I enter it from the web UI console and save it with M500 to the printer (if I remember correctly)? Does it need to be declared in a specific order/place?
Thanks again.

@deonholt actually that's my mistake.
M566: Set allowable instantaneous speed changeM205 is an alternative to M566 for compatibility with Marlin.
Open your config.g file through your web browser. and make the changes there. Don't use M500.I used Marlin for years before switching to Duet. It's a bit of a learning curve but once you get used to it it's easier and more convenient doing it through your browser.
As far as order goes look in the Gcode page i linked previously. If there's conditions as to where the code must be it'll say in the description. Personally I have my configs setup with each gcode relating to each other entered together

You can also specify M204 P T which is acceleration for print and travel moves, so you can have faster travel moves.
M205 etc are the marlin gcode commands for those things. they are also supported in reprap, so it's really up o you what you want to use.
