Enable chips in Lua, cheapen the autogen economy in XML, and point open-space farming at them. Upgrade/dismantle coeffs control build cost and refunds, sellCreditsPrice controls vendor trash value, minModuleRank controls when strong affixes unlock. 
-- default_platform_config.lua
-- cvars.sv_autogenModulesEnabled = 1
-- cvars.sv_dbgAutogenDefs = 2
<Autogen upgradeModPerLevel="0.200000" credits_coef="1000" sellCreditsPrice="1">
  <DismantleCreditsPriceCoeffs base="500000.000000" base_coef="150.000000" divide_coef="0.500000" />
</Autogen>
Lab recipe: keep the Lua switches on, halve the Dismantle/Upgrade base_coef values, raise sellCreditsPrice to 10, lower one Affix minModuleRank band. Change one number at a time; chip math multiplies several coeffs together.
Additional Notes: 

Chips stay hidden unless both Lua switches are on.
