RAMPS support needed.. January 31, 2014 05:10PM |

Hey guys...
Me and the kids are wanting to build our first 3D printer, however i was originally going to build a DIY CNC so I have some stuff left over from that.
I already have quite a bit of stuff that accumulated towards a DIY CNC Mill so might as well put it to use!
I have 4x Applied Motion STM23Q-3AE
Yes I know... Its complete overkill, but I have it sitting here collecting dust so why not actually put it to use!
As you can see the motor already has a driver built in but it can run on either step by step or SCL
SCL would be nice as it would reduce the amount of wiring required and since the units are programable its and easy to implement with a use of their 4 or 8 port router/switch boards...
Input please !!

All Reprap boards, RAMPS included, are designed for STEP/DIR operation, so that should work out of the box. SCL on the hand, will require significant development work, both hardware and software.
I would go with the Step/Dir interface.

I think for the control signals you have step,dir,enable and common, so 4 there. You could wire enable permanently on. Separately you need power for the motors, so maybe another two wires there. You'll need to make sure your power supplies can share a common ground, or derive 12V from the PSU for the motors.
Looking closer at the SCL interface, it appears to be RS232 at 9600 baud on the model you have. I don't think that would be anywhere fast enough to provide real time control. In a CNC device you could probably program a series of moves via the Hub program with a small pause between, but with a printer any pauses lead to blobby prints. I am not sure how to coordinate multiple axes, I guess that must be possible in the Hub program.
