Centroid Community CNC Support Forum

yes when the oscillator is connected on, the drive acts different example: if you had a push button that apply 24v to the step in terminal, the motor keep rotating all the time you have the button pushed, when you release the button the motor keep going until the sensor reaches the next bolt, if the...

oh ok i got it, well i can try to learn it, have you got an idea how much centroid charge for do it for me?

it only run in one direction,i didn't know that i have to pay for plc modifications, i tough acorn cnc was ready to drive any ATC,

yes i know what pins can drive the carousel, right now it is connected with 4th axis but i can put it back like it was, and leave my 4th axis alone, but im not sure if the machine owner want to pay more for modifyng the plc, maybe i will have to use the 4th axis, to do the tool change, it there any ...

this picture shows the option 1 it is the original factory configuration, wehre there was an external oscillator board that give the pulses to rotate the motor, what i did acording to the drive manual, i removed the oscillator board and connected as showing in option 2, it works ok with the 4th axis...

that picture shows the sensors that are fixed to de frame, on each tool fork there is a bolt atacched to the plate so every time the sensor detects the bolt it stops, and the other sensor only have one bolt, and it is aligned to the tool number 1.

what i did days ago, i unpluged the oscillator board from the rest of the drive, and i connected the step and direction inputs to the 4th axis of acorn, to drive the stepper with the 4th axis, but if there is the option of using like geneva system with the sensors would be much better i think, that ...

yes it does have a sensor to count tool positions, and have an other sensor for counting every full rotation. in the stepper drive there is an ocillator board that drives the stepper motor itself, with just trigger an input the stepper start to rotate and stop at each tool position, this stop is fol...

this is a video i found, it's exactly the same machine, ok i will read that geneva instructions that's what i was missing, thanks

good morning. https://www.youtube.com/watch?v=pO69We1NdcQ basically, this is the ATC that i need on my cnc router, i need a macro that when i load a program and it indicates the first tool to be used, (example T3) the spindle go to the programmed position to put it's actual tool on the fork unclamp ...
