Acorn limit switch setup
Hi ,
I finally got around to installing limit switches and ESTOP
All limit switches (6) are connected in series and are all normally closed, I verified with a meter
one side is connected to COM and the other into H4 IN-1
ESTOP switches (2) normally closed are connected in series and connected between COM and H1 IN-8
I have 24V into H1 24V IN, does it also need to be connected to H4 24V? The drawing indicates that 24V is connected between H1 - 24V and H4 -24V
I am probably missing a config setting, but I could not find this info in the FAQ
The limit switches aren't recognized at present
Thanks,
Wil

Re: Acorn limit switch setup
You need to tell CNC12 that you have limit switches connected. Looking at your report file, there aren't any Home and Limit switches configured in your Input section. You must configure those inputs in the CNC12 Wizard.wwolski wrote: ↑Sat Jan 02, 2021 5:55 pm Hi ,

Re: Acorn limit switch setup
First Determine WHICH switches will be your Home switches. You did not post pictures or give any information about your build.wwolski wrote: ↑Sat Jan 02, 2021 5:55 pm Hi ,

So we have to guess. (We can't "SEE" what you "SEE")
As Swissi mentioned, you have to assign the input in this case HOMEALL and LIMIT ALL. You do this in the Wizard.
So 3 switches in series would be your HOMEALL input
The other 3 switches if you choose to use them, which are on the opposite end of the home switches would be wired to LIMITALL.
Be sure to set up your soft limits.
You can watch the inputs trigger by pressing Alt i on your keyboard from the main CNC12 screen. Inputs are the first row on top, far left
Under the middle of the bottom row, is the legend. If you use your arrow keys, you can move a box around the input and the legend will tell you what it is, if it is not assigned, it will say INPUT X where X is the input number.
Second row of LEDs far left, the first 8 are outputs.
Have you searched YouTube for Centroid Acorn? Lots of good info there.
Once you run the 24VDC jumper around to 24V on the Input terminal block the other is connected internally by Acorn

Re: Acorn limit switch setup
Thanks for the info, the alt i command sure helps
it turns out that 3/6 switches are defective, but I'm confident that the Acorn is configured properly now

Re: Acorn limit switch setup
Yes, the diagnosic screen is worth its weight in gold. You can also watch the INPUT LEDs on Acorn to see the state change.

Re: Acorn limit switch setup
Hi, This still doesn't work, home all works but limit all does not, I vend tried moving the limit all to input 3 and it made no difference
I am attaching a sketch of how the switches are wired, and I have verified that the switches are operational and wired correctly.
If I do an ALT i command, the home all on INPUT 1 does not toggle, also I cannot move the rectangle to select another input to see it's label
I am also including a report

Re: Acorn limit switch setup
Are your switches NORMALLY CLOSED or normally open.
Your sketch show they are all normally open.

Re: Acorn limit switch setup
You should have through all your switches from one end of the other. All switches should be CLOSED.
When you home the machine, the control will hit the switch open it, back off of it, close it and move on to the next axis
You don't have your homing wizard page set yet either: You need to change from SIMPLE HOMING to AUTOMATIC HOMING
You ALSO need to set your travel limits
