Here are the TB6600 driver and GRBL settings I recommend for the CNC4NEWBIE NEWCARVE and the X-CARVE.
For the X-CARVE, I set X and Y axis at 8x micro stepping (S1 OFF, S2 ON, S3 OFF). Z axis is 2X micro stepping (S1 ON, S2 OFF, S3 ON).
The Demon ControllerTM can be used with the X-carve post processor or any of these. There are 3 post processors that include M7 and M8 activation. They will deactivate at the end using the M9 command.

How Homing Switches Work
The full Demon ControllerTM comes with LarryM's version 1.0c of GRBL. No need to flash GRBL unless you desire a different version.unless 3amp motors are not used).
I stand by my products. If something goes bad on the full controller within 6 months of purchase, I'll replace that component (If within the United States only). After 6 months, component replacement is on customer. Don't worry, failure rate is almost non existent and components are inexpensive!
Loading GRBL on the Arduino Uno
(Vcarve Pro and version folders may vary)
Loading GRBL and Testing
The Demon Controller TM is a GRBL based CNC controller utilizing the Demon Shield TM , Demon Plate TM, Arduino Uno R3, a 24VDC 15 amp power supply, and four TB6600 drivers. It comes with all the components pre wired and ready for your motor cables, limit switches, and accessories to be connected to the easy to access screw terminals.
For the CNC4NEWBIE Newcarve, I set all axis at 8x micro stepping (S1 OFF, S2 ON, S3 OFF).
STEPS PER MM CALCULATOR
(I will ship to anywhere, but you are paying for the actual shipping cost.)
$0=10 (step pulse, usec)
$1=255 (step idle delay, msec)
$2=0 (step port invert mask)
$3=0 (dir port invert mask) <-- WILL VARY BASED ON WIRING
$4=0 (step enable invert, bool)
$5=0 (limit pins invert, bool) <-- WIRES CONNECTED TO THE NORMALLY OPEN LIMIT SWITCH PIN
$6=0 (probe pin invert, bool)
$10=115 (status report mask) <-- GRBL 1.0c
$11=0.020 (junction deviation, mm)
$12=0.002 (arc tolerance, mm)
$13=0 (report inches, bool) <-- USE $13=1 TO SEE MACHINE AND WORK POSITION IN INCHES
$20=0 (soft limits, bool) <-- SETUP YOU PROPER MAX TRAVEL DISTANCE BEFORE TURNING ON
$21=0 (hard limits, bool) <-- DO NOT USE HARD LIMITS
$22=1 (homing cycle, bool) <-- YOU MAY WANT TO TURN THIS OFF AND TEST FOR CORRECT DIRECTION OF JOG FIRST
$23=3 (homing dir invert mask)
$24=25.000 (homing feed, mm/min)
$25=750.000 (homing seek, mm/min)

VFD post processors
The full Demon ControllerTM comes setup to be used with a CNC4NEWBIE NEWCARVE machine out of the box. No need to mess with micro stepping or amprage (unless 3amp motors are not used).
How To Connect a DPDT Switch FOR LASER/SPINDLE Controll
The "test" in the first video is not really a good way to fully test your switches.
See the second video for the best way.
Demon ControllerTM Post Processors
TB6600 Driver Settings
|Current steps per mm|
|Distance sent (mm)|
|Distance traveled (mm)|
|new steps per mm is:|
For 3 amp motors, I set the Current at the 2.8 amp, 2.9a peak setting (S4 OFF, S5 OFF, S6 ON).
You need to change your dir port invert mask ($3 in GRBL settings)
put in your current $3 number, click the button next to the direction the axis DOES travel. it will tell you the number to change it to in order to make the axis travel the correct direction.
Demon ControllerTM and the IOT relay
(Shown here with the screw down adaptors on.)
Use my calculator and the procedure in the video to calibrate your steps per mm. Doing this fine tunes your CNC machine's movements. Jog the spindle a short distance first to make sure you are close before sending it a longer distance. you do want to eventually do it as far as you can safely to get your travel as accurate as possible.

The motors to the drivers
Full Controller lead time is currently around 1 to 2 weeks after payment if I have Demon Shields on hand. Your payment is required for me to hedge the parts to make it. I am currently working on steps to reduce that time down to days, but we're not there yet! Please be patient while this product is in it's infancy.
