Hi laird,
Right now, we’ve disabled certain systems while in Open Mode in an effort to make sure we don’t damage your printer with an unknown resin. We don’t know the properties of 3rd party resins that may be used with the printer, and that could easily lead to cartridge dispensing over-filling the tank. The wiper is disabled for a similar reason - if the tank is over-filled or the resin has a different viscosity than we expect, it would be possible for the wiper to push resin over the edge of the tank. Heating is also disabled, as we don’t want to risk damaging a resin you purchased.
We’re listening to customer feedback about this first implementation of Open Mode, and will consider improving the functionality with future updates. Our goal with the initial release of Open Mode was to make sure 3rd party resins can be used, while limiting potential damage to the printer as much as possible.
