Schematic (Arduino + TB6560)
Schematic (CNCx Pro)
Hookups
Limit switches and buttons
- 10k res between ground and X lim
- 10k res between ground and Z-Lim input
- 10 uF cap between ground and +5V going into the hall effect sensor
- Start button connected between 5V and Y-Lim input (not ground)
- Input from display to activate return is a +5v signal on the Z-Lim input.
- Y axis should be in 8 uStep mode
- All names of the CNC xPro are labeled in the picture above and on the physical board
Fracking motor attached to Y axis
- A1 = Red = A+
- A2 = Green = A-
- B2 = Yellow = B-
- B1 = Blue = B+
Power
- + high 12-24v on + input
- - low of 12-24v on - input
Calibration
Edit the following values to calibrate the system
- Move to 18 inches
- var: double des_dist = -18;
- units: inches
- notes: distance from home (must be negative)
- Movement Speed of 5.11 in/sec
- var: des_speed_in = 5.11
- Notes: Maximum speed is 5.51 in/sec
Requirements
Script Requirements
- (done) Start input: button push
- (done) Motor 1 (drill) travels from home position towards end position
- (done) Travel speed - 5.11 in/sec (can be changed)
- (done) When drill reaches end point it stops
- (done) On "Display" input returns to home
- (done) Motor 1 remains at end position for 15 seconds Motor 2 stops and motor 1 returns to home position System restarts on next “Start input”
Setup Requirements
- (done) Program motor controller (CNC xPro)
- (done) Wiring schematics for motor 1, home switch, start button, "display" input, and power Access to source code (online)
- (done) Tutorial on setup and calibration (online)
Test Requirements
- (done) Ensure power supply and motors meet power requirements
- current power supply will not adjust to the desired 12V
- failed to pull the desired 35lb (tested 25lb and did not move that)
- (done) Test to ensure all parts are working
- see note above
- (calibration on full system needed - explus dependent) Final system calibration
