Support for 5 Stepper Motors

I am a newbie so I apologize if this is a stupid question.

I recently purchased a tinyG for my project and now realize that I have to drive 5 stepper motors. I have a standard XYZ configuration with dual Y motors driving the gantry. That makes 4 stepper motors.

My end effector will also have a stepper motor on it and that makes 5.

What is the best way to make this happen? I see that there is a possibility of networking tinyGs using RS485 (looks complicated). Alternatively, it looks like another version of the tinyG will be coming out with 5 motor support. Any sense when the new version is coming out? Does it make sense to try and network two tinyG's together?

Thanks for any help.

Regards,
James

Probably best to wait comments directly from Alden and Riley, but some additional info might be helpful to them.

Steppers - NEMA 17 or ?? Driving the Dual Y motors with the same output and proper phase wiring might be a possibility.

"end effector" - term does not mean anything to me, but I'm sort of new here as well. Would it be properly driven by the rotational axis parameters that are available? Otherwise, tinyG might not know how to interpret commands for it.

My motors are 3 Nema23's and one Nema17.
The fifth motor would be a Nema17 or lower.

An "end effector" is something placed where the router would typically go.
In the normal CNC application, the router is the "end effector."

Thanks,
James

Thanks, now I know what an "end effector" is :) !

NEMA23's are typically higher current than NEMA 17s, I'd suggest waiting for input from Alden or Riley.
