Hey, I'm a student working on a research paper that involves using 6 stepper motors for 6 axes. So far, the CNC Shield only supports 3 axes, while the RAMPS supports 5 axes. Is it possible to create a schematic for 6 axes and could anyone help me find a good adapter that allows me to use 2 CNC shields with a MEGA 2560?
Do you really need a shield format ?
Otherwise you can procure 6 stepper drivers suitable for your motors (eg Pololu - Stepper Motor Drivers) and hook them up to your arduino.
Yes ibis possible. You will have to size them to be comparable with your motors. This can be put on a circuit board and connected with jumpers to your Arduino. Doing the schematic in KiCad will allow you to take that and make circuit boards without any other CAD (Computer Aided Design) packages.
I don't really need a shield format tbh, mostly for practice for optimize solution for my research projects. but im trying to design 6 axis CNC shield
GRBL has 4 axis where as RAMPS has 5 axis. im thinking of taking cnc v3 shield concept and exaplain it. creating a schematic and model. However i need some help. at the moment I'm basically learning soild works again.
Ok will try that thank you. how good is flux ai compare to ki-cad. its a new schematic program. also i think for this design i need a ardiuno mega instead of ardiuno uno
However i guess for now worst case i can just line up 6 motors on a breadboard.
Don’t use a breadboard. 6 motors will be a lot of current going to a breadboard which is not designed for that.
Use a proto board and appropriately sized wires.
Thank you for the heads, if I need more assist. can i replay back. also i might try still designing 6 axis cnc as my final piece. but right now im testing 2 cnc with 3 axis and see if the code can have both sync.
Sure - the forum is here to help when possible
RAMPS boards have auxilary headers, and you can wire a couple of those pins up to another driver.
Here's a few simulations of 6 axes on a RAMPS:
I mean that you can combine a RAMPS with a (genuine or clone) Protoneer CNC Shield V3 with some jumpers from the RAMPS board to the Protoneer:
You could then drive maybe 9 steppers from the assembly.
Or with a Giga and multiple CNC V3s you could drive 8, 12, 16+ steppers.
