I would start with a basic questionis your 4th axis from Tormach or a 3rd party/DYI one?Do you know the details for the Driver (ie, model) and the stepper (usually 1.8 deg per step, but 0.9 are also out there)The first thing is how to add control signals for the 4th axis. Since it uses a Leadshine MX3660 as it's main controller and this is a 3 axis controllerIf I read the MX3660 and the 440 hal file correctly is it outputing Step/Dir on pins 8/9 of the DB25.
That in turn is going to the Outputs 3(step) and 4(dir)So if you wired those to the Step/Dir of your stepper driver along with gnd (depending on your driver)?You also need to connect 48V power to the driverYou'll likely need to tweak the hal file and set the SCALE to your steps per rev for your motor/driver comboThis is high level of course but from what i see in the INI/HAL files and the MX3660 manual it should be a start.anyway, that is a startPlease or to join the conversation. Hello and thank you for the reply!
Mounting of the 4th axis on the left works fine, until you decide you want an Automatic Tool Changer (ATC). The stock configuration of the rotary table allows it to be mounted only on the left side of the table of the mill.
It is a DIY 4th axis with a standard 200 step/rev motor and 21:1 reduction. I think I can figure out how to wire up the driver using your info and my limited experience.
But, the INI/HAL files and such are above my head. Is there a tutorial somewhere that explains how to access the inner working of Pathpilot? I have seen a video or two were someone modifies settings but I’d be concerned about creating a mess and ending up with a non-functioning machine.Please or to join the conversation.
