@K1111 Please create an issue in GitHub. It looks like Gcode Tool On and Gcode Tool Off didn’t initialize correctly. You should be able to work around it by filling in dummy values then clearing them. They live under Settings -> Gcode.
@Todd_Fleming I didn’t have that spot filled in, as I thought it was optional like LW3. So should it have auto generated the G1/G0 even if those Gcode settings were left blank?
They are optional in LW4. They should have initialized to empty strings, but they initialized to undefined instead.
@Todd_Fleming Gotcha. Thanks. I’ll create an issue on GitHub.
