I'm newer to machining and have a few older machines like a Hurco and Matsuura. Anytime I've had a question about something on any of these machines the support line at the companies has been awesome and got me right through my problems. I recently worked my way up (I thought) to a 2005 Makino S33 that I bought from a company going out of business and it definitely ran when I purchased it. I've had it for about a month now and I have got everything hooked up correctly and all of the fluids filled, everything powers up and I can jog XYZ by holding the over travel button in but I get a alarm code LS28 for limit switch 28 and it wont allow me to start the spindle. I called Makino just like I have done in the past with the other companies of machines I own and they told me that they know what it is and that LS28 is now referred to as LS905 but if I want them to tell me where the limit switch is I have to pay them $2500 for yearly phone support. This is insane to me!! I've also searched my manuals and can't find LS28 or LS905. I will include pictures of my conversation with Makino and of the alarm code, any help will be greatly appreciated!!! THIS WILL BE THE LAST MAKINO I EVER OWN!! Thanks again everyone for the help and hopefully I can get this machine going with your help.
