Well I'm not sure how I have proved this my self.? but yes I agree if the system isn't designed to slave motors independently then it can't, but most systems like Mach3 or Linux CNC that use slaved motors independently can which is more what I was meaning. Your system appeared to just be doing what they do, but they don't Auto square the gantry to a set amount, they just move to switches that you set to square the gantry. (actually, I think Linux CNC can now.!).

Anyway good job all the same, I wasn't knocking your efforts just didn't see any auto squaring(offsetting) going on only hitting switches.!

I'm attempting to use the standalone DDCS controller for this machine Jazz rather than a PC. Before making this custom board I read Boyan's thread on these controllers here:
http://www.mycncuk.com/threads/10187...ion-controller

I was just quoting your posts in that thread where you tested one of these controllers and proved that it was not possible to slave motors and this obviously being a problem for machines with >1 motors per axis. Here you go:

Maybe your miss understanding what was meant.? It was me who said doesn't work and I'm talking about Slaved axis. As in two motor/drives on separate outputs working as one axis.
That controller is exactly the same one I have and it DOESNT allow slaved motors. This video is just showing it working as 3 + 1 which the controller will do no problem. The fact they have twin screws means they are using dodgy practise of using one output to control two drives or even worse one drive to control two motors.?

IT DOESNT SLAVE TRUST ME.!!!!

I'm using the 4-axis version with much newer firmware but it still doesn't support slaving, hence the creation of this board to add the capability without the operator or the controller needing to know it is there, it just works passively in the background when required. The 4th axis is obviously then still available to use as a 4th axis as well.

For me the most important function is (re)squaring the gantry before every job, I think you are more concerned with setting up the initial squareness without moving targets. To be clear none of the methods implemented in any of the controllers perform auto squaring they all require some square reference setup on the machine to search for, whether that reference is the actual switch actuation point or some other position offset from it. Just like none of them support auto tramming or auto planaring (new word).
