NCF with Use Assemblers option checked and Assembler with Nanite Factory Queuing checked

For this setup i'm just Placing the frame for a light armor block and letting the NCF build the rest (24 Steal Plates)

Setup - Working as expected no extra items in inventory after build
1 NCF Use Assemblers checked
1 Assembler Factory Queuing Checked

Setup - Working as expected no extra items in inventory after build
1 NCF Use Assemblers checked
2 Assembler Factory Queuing Checked [cooperative mode unchecked]

setup - Working as expected no extra items in inventory after build (seems NCF does better job of speading out the workload)
1 NCF Use Assemblers checked
1 Assembler Factory Queuing Checked [cooperative mode UnChecked]
3 Assembler Factory Queuing UnChecked [cooperative mode Checked]


setup - Breaks Use of Assemblers nothing is built (or partly built)
2 NCF Use Assemblers checked
1 Assembler Factory Queuing Checked [cooperative mode unchecked]

setup - Breaks Use of Assemblers
1 NCF Use Assemblers checked
1 NCD Use Assemblers Unchecked
1 Assembler Factory Queuing Checked [cooperative mode unchecked]

setup - Extra Parts (looks like both NCF's orders 24 steel plates)
2 NCF Use Assemblers checked
2 Assembler Factory Queuing Checked [cooperative mode unchecked]




Other negative effects
While Grinding something NCF Queue's Assembler to build parts

building larger items assembler is FILO(first in last out)... not FIFO(first in First out) NCF is inactive while assembler pretty much builds everything then finishes building
(jump drive build order is Steel plate 20 Large Steel Tube 40 Metal Grid 50 gravity generator components 20 Detector Components 20 Power Cell 120 Superconductor components 1000 computer 300 construction components and the NCD feeds this is to the assembler in that order[needs to be reverse order])

i created a small test world if you want/need.
