Troubleshooting & Community Support — Rules

  1. One issue per post
    Please keep each thread focused on a single issue to make troubleshooting easier and easier to search later.

  2. Include system details
    When posting, include:

  • Machine model

  • Mach4 profile (Inch/Metric)

  • Software version (or update date)

  • Controller type (if applicable)

  1. Explain the problem clearly
    Describe:
  • What you expected to happen

  • What actually happened

  • When the issue started (first day, after update, after wiring change, etc.)

  1. List what you already tried
    This helps avoid repeated suggestions and speeds up the process.

  2. Provide proof whenever possible
    Include at least one of the following:

  • Screenshot of the error message

  • Short video of the issue

  • Alarm/log text

  • Snippet of the G-code around where it fails

  1. Safety first
    If anything moves unexpectedly or seems unsafe:
  • Hit E-Stop

  • Stop testing immediately

  • Do not bypass safety devices to “see what happens”

  1. Be respectful and constructive
    No shaming or hostile replies. Everyone is here to learn and improve.

  2. Mark solved + share the fix
    If your issue is resolved, please reply with what fixed it and mark the solution if available.

  3. Search before posting
    Try searching the forum first. If your issue has already been discussed, add your details to that thread instead of starting a duplicate.
