2025.10.0 Release

· 4 min read

Now Available: Resolver 2025.10.0​

The latest release of Resolver is now available! Read on to learn more about Resolver 2025.10.0

Resolver 2025.10.0 is enabled by our latest connectors:

  • Process Simulate Connector 1.10.0
  • Visual Components Connector 1.10.0
  • MELSOFT Gemini Connector 1.10.0

Compatibility information for supported simulation tools and versions can be found on the minimum requirements page of the Resolver documentation site. We recommend always downloading the latest version of the Resolver Connector, regardless of the version of the simulation tool you are using.

FANUC Robot Model Update​

In mid-October, Resolver switched to a new internal FANUC model that catered more to the unique velocity-based smoothing methods used by FANUC. Initially, this model generated paths that were more accurate (collision-free) than the previous radius-based model, but many users reported poor performance in smoothing generation at vias. We are happy to announce our biggest improvement to the model since initial release. Enhancements include:

  • Improved Dynamics Calibration process that handles specific edge cases that were previously skewing general dynamic values.
  • Bug fixes to the internal FANUC smoothing model.
  • Engine enhancements to handle clearance violations better, which significantly affects FANUC robots that require large jumps in CNT values to improve cycle time.

In general, users should see significantly greater use of large CNT values at vias in this release. Internal testing showed generated paths that previously had 90% FINE term types now have 90+% of vias with CNT70 and above. Additional work and specific edge cases that users should be aware of:

  • Higher CNT value does not monotonically improve cycle time on FANUC robots. We have specific cases identified where CNT0 - CNT40 produce slower cycle time than FINE. If you (the user) identify a case where Resolver is producing a FINE term type, but a significantly higher value is possible without violating clearances, please open a support ticket and provide the study.
  • The Resolver engine is biased towards producing few vias with large smoothing in generated paths, which always leads to better cycle time in radius-based smoothing models (non-FANUC). There are edge cases where the engine would need to produce significantly more vias to shape the path with large smoothing. Typically, this occurs in areas where there is a “tunnel” effect of clearance limitations on both sides of the required motion. We are asking for feedback and examples for this edge case:
    • As a user, would you prefer 2 vias and lower smoothing values or 15 vias with higher smoothing values and slightly better cycle time? Please submit feedback via the support portal or directly through other support channels.
    • Please submit examples of these scenarios if you find them. The best way to improve Resolver is through real-world problems.

Resolver Product Updates​

Enhanced Cloud UI for study management and run iteration

  • Improved: Management of folders and studies
    • Users can now drag and move folders containing studies.
    • Active runs will now be ordered by start time.
    • Study names are now displayed on the Active Runs Page.
  • NEW: Start a new run from a previous run
    • There is now a copy icon on each run within a Study to be able to start configuring a new run from a previous one.
    • Users can access this feature from the Study level where all runs for a Study are listed.

Folder Structur

Process Simulate Connector 1.10.0​

Improved experience when using FANUC Robots and FANUC RCS

  • NEW: CNT100 at Spotwelds for FANUC robots
    • When using FANUC robots, term type will be copied from the original location if not blank.
    • If the term type is blank on the original weld location, the import process will automatically set CNT100 for those locations with FANUC-Rj and FANUC-Rj-Japan controllers.
  • Improved: RCS Model Alignment
    • If there is a kinematics mismatch between RCS and Process Simulate during calibration, users will now receive a warning if deviation is greater than 10 mm.
    • If users give a Move command, it will go to the same joint position as a Joint command. If users have mismatching joint values for a target, users will now get an error to check the RCS model.
  • Improved: FANUC RCS dynamics calibration
    • Motions will start near the home position, reading max cartesian speed from the controller instead of the simulation, and the weld gun calibration method is now more refined.

Visual Components and Gemini Connectors 1.10.0​

Bug fixes and user experience improvements

  • Improved: Study Export
    • If an export is aborted, the incomplete study will now be removed from the server.
  • Improved: Log in experience
    • Authentication between the Export and Resolver tabs in the viewer is better synchronized to detect log outs and prevent stale tokens.
