Chris' Grizzly G0704 Acorn Update

[ChrisAttebery]

I programmed a little demo part and made a video of the machine running it. I’m running 180IPM rapids right now. I was using 240IPM with the Mach3/SmoothStepper setup but I’m still getting used to the Acorn.

Thanks Marty. When I have some time to put something a little more polished together I’ll post it there.

Yesterday I received the Renishaw MI8 interface unit and a few goodies from Amazon. I mounted the MI8 in an aluminum amplifier enclosure. On the control side I mounted a GX4 connector to provide 24V, GND, probe detected and probe triggered. On the probe side I mounted a DIN5 connector to provide probe +/-, probe detect and GND. I also mounted a super bright LED on the probe side. I mounted this interface unit under the keyboard tray next to the enclosure door for easy access.

I also finished up the probe to R8 adapter. I pressed the tapered SS insert out of the Renishaw inductive adapter. I bored a pocket for it in my adapter. I used a slip fit and Locktite 609 sleeve retainer to attach it. I wired up a DIN5 connector with probe detect, trigger +/-, and GND. The probe detect signal is tied directly to GND.

The LED on the interface lights up when the probe is plugged in. When the probe is tripped the LED turns off.

I’d like to see a status message and/or a pop up message when the probe is plugged in and the spindle is disabled. I’ll have to look into how to do that.

I do see a status message in CNC12 when the probe is tripped.

Now I just have to wait for the NIB MP3 probe I purchased to show up.

Hey Chris was hoping you could tell me how you went about wiring the mi8 interface board to the acorn. I’m looking at your board wiring and it appears you wired it different from the schematic from Renishaw. I see you have common jumped and running out towards the acorn. Is this for the probe detect? Hoping you could steer me in the right direction as I purchased and mp3 and mi8 as well.
