The braking time does not need to be excessive. You will be making your own tool change macro. You will be limited in your braking time anyway by motor efficiency, max drive current and resistor heating. I would start at three seconds, then decrease from there if you are not exceeding any ratings. Y...

I just saw "it has an output configuration of 230V at 272HZ, 7.5KW for the spindle motor. spindle" so assumed 230V.

Either way, just choose the resistor that the manual says for the appropriate configuration and it will be all good.

The table in the manual gives suggestions for resistance values for nominal and fast deceleration. The actual deceleration speed that is achievable depends on the rotating mass of your motor, spindle etc. Generally CNC machines have very low spindle inertia compared to say driving a huge fan or flyw...

Can you tell me the error it is generating? It may be over volts on deceleration. If that is the case then a resistor is required. The delya drive can handle a certain amount of load but after that needs a resistor to dump the deceleration energy into. I used a large resistor on mine but probably di...

It's been a long time since I had to choose a PLC program but from memory they are all available inside the CNC12 installer zip.

Ok, your call on that one. But he will require all the inputs wired and a list of the wiring locations.

Something tells me that one of the centroid examples is already set up to do a binary code tool changer.

Thanks for sharing the video. I still don't know much about how that mechanically works and what inputs/outputs are involved. Looks to me that whatever you are doing with those buttons needs to be done by the controller. So a good place to start would be to wire them to the controller and write some...

Attached is a new report. I checked Windows zoom level. It is on 150%. I set it back to 100% and the G code display came right. But everything else in Windows is too small to see or press with my fat fingers! So, I would like to run Windows at 150%. This is a full touchscreen only setup, no mouse or...

Yes in portrait mode. So cnc12 takes up the top part of the screen. I am not using any skinning features that relate to visual stuff. Well, none that I am aware of. No VCP. I will get a report when I can get to the machine in a few days.

Remind me where 1024 comes from?
