Acorn CNC12 v4.14 has been released.

I hope the next version doesn’t take away the ability to use the db25 step/direction with the screw terminal enable signal.

No plans to do that

Awesome! Thanks Keith!

I have updated to the 4.14. I need to add two inputs that are not listed in the pick list,(Pause and Resume). I have them tied to input 4 and 6 on the Acorn board. From the Alt i screen they are working as they should. How do I get Centroid to get them to pause and resume the machine?

So you want to have a button to use feed hold (keyboard shortcut: space bar) and cycle start (keyboard short cut Alt s)

Thanks for your help

I used that tutorial to add an external Cycle Start. Worked great!

Just remember once you create a custom PLC program to save both the acorn PLC. Source (.src) and the .PLC program in the CNCm directory to another location because if you use the wizard after you have created a custom PLC program, The Wizard will overwrite your customizations which will be no big deal if you have a copy of it which you can simply paste back into the Cncm directory

Out of curiosity, can you restore your old settings by using a "Report" from the older version or is it mandatory to do the Wizard setup?

I'm just curious about all my tool-offsets etc.

NO, do not use restore report from an older version of Acorn CNC12.
Keith does go over retrieving your tool offsets and tool library in a video.

For the benefit of the Beginners and Newbies I have to insist that my method to setup a Metric systems is definitely the much better way to do it and here is exactly why. So if you are a Beginner/Newbie, read this and make up your own opinion:

As a Newbie, you don't know what a good value is for some of the parameters in the Wizard and you might not even know what some of the parameters are used for. So in that case, you just accept the default value that's being presented by the Wizard. Now let's have a look at these parameters. When you launch the Wizard right after installing CNC12, you will get the following screens:

All of the default parameter values are for an Imperial system. Now when you switch from Imperial to Metric in the Wizard, all these default values stay the same and they do not make sense for Metric systems as you can see from this screen shot:

Some of these parameters are 25 times to small for a Metric system. As an example, your x1 Jog Increment is now set to 0.000787mm. Also the recovery distance for your probe is now 0.05mm and the slow probing rate is 3mm/min which is way to small. So if you are going to accept default values for some of the parameters, you might end up with parameter values that are not suitable for a Metric system.

If you are going to switch CNC12 to Metric before launching the Wizard, you will get default parameter values in the Wizard that make sense for a Metric system as you can see from these screen shots:

Capture4.JPG
Capture5.JPG

As you can see, these default parameter values now make sense for Metric systems.

This is Centroid's product and they have the right to suggest what they think is the best way to install their product. I gave you all the facts above and that should be enough for you to make your own decision what's the better way for you.

I can concur with these findings, I am struggling to get my Metric system to accept anything but the default Imperial values. I am going to de-install CNC12 and start afresh to cure the issues. When you say "If you are going to switch CNC12 to Metric before launching the Wizard", how does one do this as the Wizard is now started from within CNC12. I was going to request an install for 4.12 and set that up first but can't find the download anywhere...

Bruce,
Set the wizard to metric and type in metric values, its that simple. what's the issue?
