  1. Re: Looking for a 5-axis cnc controller with RTCP

    This is another choice: https://rosettacnc.com/en/index.html#

    RosettaCNC is an industrial CE certified CNC for multiaxis RTCP or TCP movements made totally in Italy with Fanuc G43/G43.4/G43.7...

    Re: Best CNC controller

    Let's have some clarity.

    With the NC program, you define the path for the tool to run.

    The CNC control, once it has transduced the NC commands into movements of the joints (physical axes) will...

    Keeping it simply, the Jerk in a movement system is the derivate of acceleration. In case of a constant accelerated system the jerk is infinite at first change of speed. The strenght of jerk effects...

    Re: Mach4 5 Axis Saw profile

    To mill with a Saw you need of a CNC board with 5-axis multi-machining RTCP with G43.7 and a CAM to create right G-Code to keep TCP on saw cut border element.

    Good test !

    Multi-axis speed depends by many factors.

    Re: Help!! Is Masso a 5 axis option

    If you want to get into 5-axis continuous machining you need an RTCP capable CNC as well as the Rosetta CNC has.
    RTCP is very important with 5 axis for a lot of questions but overall to get a fluid...
  16. Re: Can you recommend 5 axis controller board?

    When you work with 5 axis RTCP feature is a must, so search a CNC board which support RTCP.
  17. Re: Can you recommend 5 axis controller board?

    Depends by 5 axis kinematics.
    If the kinematics is a classic Head/Head or Table/Table the post-processor is simple to do. In a lot of CAM's the math is already made and you need only to configure...

  23. Re: 5 axis head/head homemade CNC - gcode generator

  25. Re: 5 axis head/head homemade CNC - gcode generator

    To manage Head/Head CNC the RTCP feature is a MUST !
    Table/Table configurations can, in same way, generate 5 axis toolpath without RTCP but with a lot of limits:

    - precision
