The short version

  • Only Formlabs PreForm has a free tier, so it costs nothing to try first.
  • Each has a real cost: Formlabs PreForm preForm only drives Formlabs printers, so the free software is really an entry cost to a closed hardware and resin ecosystem rather than a tool you can keep if you change machines.; Guidewheel current draw shows that a machine is consuming power, not that it is producing good parts, so scrap, rework and quality still require operator entry or additional sensors and the OEE quality factor is not measured automatically.
  • They diverge on capability: Formlabs PreForm covers Automatic orientation, Guidewheel covers Clamp on current sensing.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Formlabs PreForm

  • PreForm only drives Formlabs printers, so the free software is really an entry cost to a closed hardware and resin ecosystem rather than a tool you can keep if you change machines.
  • Formlabs resin is sold in proprietary cartridges, and the ongoing consumable cost over a printer's life dwarfs anything a paid slicer would have charged.
  • Third-party resins can be used only through open material settings that step outside validated profiles, which affects print reliability and the comfort of warranty support.
  • Parameter-level control is deliberately limited compared with open slicers, so advanced users cannot tune exposure and layer behaviour the way they can on an open platform.
  • It is Windows and macOS only with no Linux build, which is awkward for research groups and labs standardised on Linux workstations.

Guidewheel

  • Current draw shows that a machine is consuming power, not that it is producing good parts, so scrap, rework and quality still require operator entry or additional sensors and the OEE quality factor is not measured automatically.
  • Cycle counting depends on a distinct load signature for each cycle, so machines with flat continuous draw such as ovens, some extruders and continuous mixers give poor or unusable part counts.
  • Installation involves fitting a clamp around a live power conductor inside or near an electrical panel, which in many plants requires a qualified electrician and a scheduled shutdown rather than a plug in setup.
  • It is monitoring, not execution, so there is no routing, scheduling, work order or traceability capability and it must sit alongside an ERP or MES rather than replacing either.
  • Pricing is per monitored machine, so a plant with two hundred small machines faces a bill proportional to machine count rather than to plant size, and the economics work better on fewer larger assets.

Answered from the vendors’ own pages

Formlabs PreForm: Is PreForm free?

Yes, with no licence fee, subscription or installation limit. It is free because it only prepares jobs for Formlabs printers.

Guidewheel: Does it work on machines with no controller or network port?

Yes. That is the reason it exists. It measures the power cable, so machine age and protocol are irrelevant.

Formlabs PreForm: Can PreForm drive a non-Formlabs printer?

No, and it never will. It is the front end for Formlabs hardware, which is where the revenue is.

Guidewheel: Will it count parts?

Sometimes. It works where each cycle produces a distinct electrical signature and does not work on continuous draw equipment.

Formlabs PreForm: Can I use third-party resin?

Only via open material settings, which take you outside validated profiles and the reliability those profiles are tuned for.

Guidewheel: Do I need IT involvement?

Less than with controller based monitoring, but you do need electrical work to fit the sensors and a path for the gateway to reach the internet.

Formlabs PreForm: Does it run on Linux?

No. Builds are provided for Windows and macOS only.

Guidewheel: Is it an MES?

No. It monitors equipment. Work orders, routings and traceability need a separate system.
