Check Printer setting on Chitubox startup!

[MarkE]

Running V1.5.0 and under settings for machine type there is no option for selection. mine is simply set to (default) This applies to the name as well. Any ideas?

Left hand side of the Settings page, above where it says Default, there's a button to add a new printer. Click this and pick Elegoo Mars from the list to create a new machine, which will now appear underneath the Default printer.
