Ok, yes, upgrading to new hatch fill extension, have loaded the the eggbot_hatch.inx, eggbot_hatch.py files. started Inkscape and the look under EggBot extensions menu and no Hatch Fill. Just downloaded the 3 files from plotink. Installed them. started Inkscape and hatch fill still does not show up in the eggbot drop down. the old version is still in eggbot contributed menu.
The hatch files were copied from github, and had a date of march on them.
And only one copy of Inkscape on the machine.
