I would be awesome to be able to change feed rates after the g code has been uploaded
This is a highly demanded feature, and it was already requested here in #894, #1014, #6972, and #15007.
Sometimes it’s better to add to an existing request. Anyway Onefinity stated they look into the Feature Requests category regularly.
The new Onefinity Elite Series with Masso G3 Touch Controller have this feature.
