Material inventory and budget

Plan the batch before buying another spool.

Carry the material route and density forward, enter compatible filament already on hand, then separate physical consumption from the whole-spool cash purchase still required.

Connected print budget

Carry the selected material into a batch plan, separate filament consumed from on-hand stock, and calculate only the whole-spool cash purchase the job still requires.

Material consumed

Slicer mass, quantity, and the visible process allowance define what leaves inventory.

Inventory before cash

Compatible on-hand filament is applied first; only the remaining demand is rounded to whole new spools.
