3D Printed Project – CNC Alignment Collar for Spindle!

Please visit ift.tt/1PJb2UK for more information on this and many other projects! As in this episode, we will be taking a look at the 3D printable alignment collar we created the 800 watt water cooled spindle on the 3040 CNC. We created this in open Open SCAD and have also created a Custmizer version of this on Thingiverse (here: ift.tt/2vMPnZc ) so you can match it to your needs!

We also recommend this dial indicator and USB cable below to feed the measurements directly into your computer! In addition we will be publishing a video soon on how to use this to set your GRBL numbers as well how to upgrade to GRBL 1.1 so stay tuned!

2 Watt Laser Cutter and Engraver Project Part 8 – First Test Cuts of Machine!

So we connected the laser and sorted the PWM pin for TYL (the -Z pin) and got the whole thing to work!  It was exciting to see the whole thing work the first go around as we built it all the way up from a 2 watt laser diode to the maker rail motions running GRBL!

2 Watt Laser Cutter and Engraver Project Part 6 – Setting up the CNC Proto-Sheild

In this episode we will look at configuring the CNC Proto-Shield for the Ardunio and GRBL for the laser cutter.  For more information on the CNC Proto-Shield click this link, also for the configuration page click here.  This has turned out to be a great little board for the money and highly recommend it for any type of CNC project which your working on!

Vectric Cut2D Post Processor for Laser Cutter

 

In this episode, we will look how to a create a post processor file for Vectric Cut 2D to drive the laser cutter on our Probotix Fireball v90.  This should also work for all GRBL based machines like the Shapeoko or the XCrave too.  Below is the code for the millimeter based post processor file:

Spindle and Laser Control for CNC Router using Gcode

In this episode we will look at using a dual relay board (amzn.to/1MeJCmN) connected to the GRBL controller to on and off either a spindle or small laser attached to the mill (we will be adding a 2 watt laser in another episode).  This is is current using pin 13 which is set control spindle direction as in stand PWM mode pin 12 for spindle enable does not respond to gcode commands and requires a change in the configuration.f and a recompile with upload.  I got the below table from (www.shapeoko.com/forum/viewtopic.php?f=3&t=5803) and it is a good reference if you want to make changes.

 

Disabling VARIABLE_SPINDLE will revert Grbl to the old pin layout, where spindle enable is on D12 and direction on D13. With it enabled, spindle enable/PWM is on D11 and direction on D13.

EDIT: Here’s a chart to make it a bit clearer.

VARIABLE_SPINDLE enabled:
D11 = Spindle enable/PWM speed
D12 = Z-limit
D13 = Spindle direction

VARIABLE_SPINDLE disabled:
D11 = Z-limit
D12 = Spindle enable (on/off only)
D13 = Spindle direction

VARIABLE_SPINDLE and USE_SPINDLE_DIR_AS_ENABLE_PIN both enabled:
D11 = Spindle PWM speed only
D12 = Z-limit
D13 = Spindle enable (on/off only)
