OSAI conrol need help

Pavlo Member

Writing here due to find out that some questions about OSAI CNC have answered and that is great.
Appreceate any help/suggestion or advice as offical support of OSAI said that they limited and can't help.
So my case - I have Uniteam Wind 40 OSAI 10 controled CNC 2004.
Mostly everything is working good, I have tune postprocessor for Powermill(if somebody required could share) however few items is required resolution.
1.(Major case) In this cnc C axis is unlimeted, however in case toolchaning that G79C is just rolling C back :( - that could have unpredicted movements and I should to split program in case C has long path.
And during homming procedure - that is great and doesn't metter how long C was just till sencor and thats all.
My question here - does anybody knows command for OSAI for G code for axis homing (G79 is not options as I mentioned above) or any other solution (exept C axis limits) how to not spin back all path for example for C 25000 :(
Or maybe some configuration in CNC - any ideas wellcome and will be cheked.
2.(minor case) Wind40 has 2 separate tables (Y & V) and I would like to use them as separate however faced with case when Y standalone - fine. if V standalone - Y has tiny movements and sometime faced with Y limits which is stop all program. During invetigation I found out that case in (TCP,1) - without TCP Y is not moving only V moveing however that ruine whole path :(.
In additional if V standalone center tool correction doesn't not apply as well even with TCP.
Please advice if you have any suggstion or ideas.

Don't have my Biesse Arrows with OSAI 10 controls any more but if you google OSAI 10 manual you will find the programming manual online. Should be first suggestion.

I still have a few bits and pieces of posts kicking around maybe even including one that was done for pendulum processing. If you send me a DM I can send you what I have.

While the G79 command might not be suitable due to its behavior, you can look into creating a custom homing command or macro. In many CNC controllers, including OSAI, you can define macros that perform specific tasks. For instance, you might create a macro that checks the current position of the C-axis and then moves it to a safe position before performing a tool change.

You can explore if your OSAI controller allows for user-defined macros. Typically, these are defined in the controller's configuration files or through a setup interface. The macro could use conditional statements to decide the shortest path to move the C-axis to a homing position or directly to the sensor position without a full rollback.

    FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
