Check and make sure you have installed the ameba 1 board to Arduino IDE via adding this link into “additional boards manager URLs” under “Preference”, and install it in “board manager” under “Tools”,...
- 3d Print the Motor bracket, Linear stage brackets, Carriage top and Bottom, and Line-holding/guide pieces. NOTE: Use opaque, dark material for this (i.e. black PLA, and NOT the semi-clear material I have here). The flags for the limit switch...
Using a soldering iron, press the M3 heated inserts into the top of the carriage, and into the Linear Stage Bracket (where the optical sensor will be mounted)
- Slide 2 LM8UU linear bearings onto the 8mmx150mm rods. - Partially thread the brass nut onto the lead screw - Press all three into the carriage bottom (this was a tight fit for me w/ my printer - you may need to tweak the design a bit) - Attach the...
-Attach Optical Sensor/Limit Switch to linear rail bracket - Press the 8mm rods into the linear stage brackets - Attach shaft coupling to the motor, and mount motor onto the bracket - Attach potentiometer and solder wires to its three contacts
- The CNC Shield axes used for this project are X and Y. - Set all of the microstepping mode jumpers (microstepping = 1/16) for both X and Y drivers- Attach the shield onto the Arduino- Attach the stepper drivers the correct axes locations on the...
- Connect the optical sensor anode pin to a 105-220Ω resistor. The goal here is to set the current for the IR LED to somewhere in the 15-30mA range. - Then connect the Collector pin to a 10k-100kΩ Resistor. The optical flag should...
Upload the sketch in this project onto the Arduino. Depending on what your pickup height and attachment situation is, you'll need to adjust these two definitions:#define MAX_XPOS 64000 #define MIN_XPOS 15000 Note: this firmware also assumes...
- First, get a feel for the spindle. Because it's a stepper motor, there will be some unhelpful mechanical resonances (the microstepping helps with this a bit), but overall it needs to be gradually accelerated to its maximum speed. Get a...
