I connected arduino + cnc shield.
So i can see only cnc shield.
It gave all pins a name(such as SpnDir coolEn, E-stop)
But i will not use it cnc.
I just used shield for 3 driver (adjusting electric characteristics)
I think there 2 selection.
The pinout diagram here:
Shows where the various Arduino pins appear on the CNC Shield V3 board. For example, to connect to A0, A1, and A2 pins, use the Abort, Hold, and Resume pins.
Thank you !
That is what i want.
Today, I learn a word -schematic and how to control CNC shield for personal use.
But, i have some problem. From data, I found D2 pin, use X -STEP.
Then, I found X-STEP in shield. But it have 2pins......... it make me sad.
why they have more pins? - from usually using jumper, i guess they are boolean types. ( with jumper = closed(1) // not with jumper = open(0))
X-STEP (D2) and X-DIR (D5) signals go to the Step and Direction pins on the X Stepper Driver socket. You can leave the X driver socket empty and use the D2 and D5 pins for whatever your want by connecting to the pins near the edge of the board (D2 and D5).
Sometimes you need a bigger driver than will fit in the driver socket. To do that you leave the socket empty and use the D2 and D5 pins for an external step-and-direction driver.
Thank you.
I understood what you want to talk.
and i will use 6 stepper motor. What i really want to know is how to connect more motor drivers with this v3 shield. But Q1. uno is unsuitable. right?
Q2. How to work X-EndStop pin in V3 shield. and how can i use X-Endstop pin (=D9 in arduino) for other device. it is different with D2 or D5 (these are just arduino pins D2,D5. I just connect other devices)
lastly, I really thank your advice.
Right. The UNO with CNC Shield only has room for four stepper drivers.
The UNO by itself has enough pins to drive Step and Direction on 6 external drivers (12 pins) and one Enable pin shared across all 6 external drivers. that leaves 7 pins (UNO has 20 total) for Serial, I2C and three analog or digital inputs/outputs.
Do you need any inputs or does your design just move the six steppers in some fixed pattern?
