Default Generic Marlin Machine start g-code

[HappyMark93]

Is your feature request related to a problem? Please describe. Initial "Default" settings should be safe to run for of shelf and generic printer configurations by setting specific properties of printer.

1. Where is "EXECUTABLE_BLOCK_START" g-code coming from? How to disable?
2. Current default generic marlin machine start g-code overrides M204 from "EXECUTABLE_BLOCK_START'

Which printers will be beneficial to this feature Custom builds, modified configurations, currently not supported of shelf printers.

Describe the solution you'd like

1. Line : G1 X205.0 E19 F1000 should be changed to take in consideration build plate dimensions.
2. option to activate (add to g code output) M201,M203,M204,M205 command should be added to Motion ability tab of printer settings, and default to unchecked box.
3. Current default generic marlin machine start g-code overrides M204 from "EXECUTABLE_BLOCK_START' it should be fixed by using one or another option.

Additional context My G-code output:

Hello, I'm facing the same issue, were you able to find a solution to disabel EXECUTABLE_BLOCK_START?

[HappyMark93]

Unfortunately no :(

crud what is this thing, I have the same issue

[joe2112]

ok I stumbled on it, under the printer edit the defaults, on the motion ability tab uncheck emit limits to G-code, if m200 and other speed limit commands are not supported.

I unchecked that box but I still get the following. It is mainly annoying because I want to heat my bed first.

; EXECUTABLE_BLOCK_START
M73 P0 R249
M104 S210 ; set nozzle temperature

It is working for me... M104 is not a part of printer motion configuration. Try to enter custo gcode on Machine G-code tab -> Machine start G-Code. If I remember correctly, auto-set-up code will be removed as soon as you enter custom code there.
