Quick answer
What to do first
Biotech’s first mechanitor needs a mechlink and a pawn who can perform the required research and mech work. Then establish the basic research, gestation, control and charging loop before expanding. Bandwidth, power and waste handling are operating constraints, not optional extras.
Match your symptom
| Symptom | Likely cause | Check | Next action |
|---|---|---|---|
| Pawn has no mech control | No working mechanitor qualification | Check mechlink and pawn restrictions. | Obtain a valid mechlink and choose an eligible pawn; psychic deafness is a blocker. |
| Cannot start the first gestation | Research, worker or facility is missing | Check Basic mechtech, electricity and the gestator requirements. | Complete the prerequisites and use a capable mechanitor. |
| Mech will not join the control plan | Bandwidth or control setup limits it | Inspect mechanitor bandwidth and assigned mech groups. | Stay within capacity and assign the intended work mode. |
| Mechs stop after initial use | Charge or maintenance loop fails | Inspect recharger, power and waste output. | Provide dependable charging and a planned waste-storage solution. |
Meet the mechanitor prerequisites
The mechanitor route starts with Biotech, not with capturing arbitrary hostile mechs. A mechlink makes a suitable pawn a mechanitor. On many new maps, destroying an ancient exostrider midsection starts a route to a ship containing a dead mechanitor and hostile mechs; another route is a mechanitor-complex quest. Recover the mechlink from the corpse and have an eligible pawn self-install it. The Mechanitor scenario starts differently and does not normally spawn that exostrider.
Build the first working mech loop
Choose the pawn before spending on infrastructure. Work incapabilities matter: a pawn unable to handle relevant smithing or intellectual work can block important mech tasks. Check those limits as well as health and psychic eligibility.
Resolve gestation and control blockers
Build the smallest complete loop you can support. Complete Electricity and Basic mechtech, make a basic subcore at a subcore encoder, and supply the materials for a simple mech in a mech gestator. A mechanitor starts the gestation cycles and removes the finished mech. Assign it to a control group, choose Work for labor, and provide a compatible recharger. More gestators do not solve missing qualification or insufficient bandwidth.
Plan charging and waste
Plan charging and waste before increasing the workforce. Check the correct recharger and keep it powered; wastepacks are a continuing responsibility. This opening setup deliberately stops before boss-call progression, advanced mech rankings or claims that every captured mech can be tamed.
