    Dual motor gantry homing?

    Hello,

    First off, I've been using planet cnc with mk3/4 on two machines for 2+ years and it works really well. Compared it with a few other controllers in real semi-industrial applications and it's significantly faster/smoother.
    Which is why I want to use it on my new builds (a few machines actually), large routers with two motors rack&pinion driving a wide and rather heavy duty gantry. For that I would absolutely need to be able to home both sides of the gantry to maintain squareness, automatically.
    Connecting the two motors via belt is simply not an option, nor is it a real solution in this case.

    I've searched the forums and the manual and seen old posts about that not being possible with Planet cnc, despite repeated requests. I've seen some users that hacked somewhat of a solution, but making my own electronic boards and such is something I really don't have the time to fiddle with.

    Is this something that's possible to implement without making my own electronic circuits? or perhaps already been resolved?

    Cheers

    In TNG it is possible to create homing script that does this. I don't have script here right now but if you are not in a hurry then wait for tutorial on this topic.

    Awesome, glad to hear that.

    Yes a tutorial will be greatly appreciated! Guess it's going to be time to take the plunge and make the move to TNG.

    Cheers!

    Next TNG version will be awesome. I'm working on it right now and I'm very excited. But there is a lot more work to do.

    Can't wait. I'm very pleased with TNG, it's proving to be reliable and smoooooth!

    Made the move to TNG a couple weeks ago on my smaller machine and so far really impressed! runs smoother and quieter, and the ability to customize the ui buttons/tabs is great.
    Now just need to sort out the dual motor homing so I can get on with the larger routers..

    So any chance of that tutorial or some help with a custom homing script?

    Cheers!
