I have the I2R 8 and want to try using a drag bit which requires the
spindle to be off during file run. What is the method to shut off spindle?
Can it be done outside the G-code or need to be written in?

I have the AR8 and I had read that we can turn the spindle off by turning the knob on the control box to "0." I did a search and didn't find that recommendation but recall it in one of the discussions. You might want to try that and see if it works. Otherwise maybe someone who has the I2R 8 will chime in.

Do you have some objection to turning it off within the software? Consider this...the file is NEVER going to be used with a spinning bit, so why not establish that in the software? That way, nothing that you (accidentally) might do on the controller itself is going to start that diamond drag engraver spinning. Nothing to remember, nothing to forget when running the file.

fleet56 - Here is a posting on the Vectric forum that might help forum.vectric.com/viewtopic.php?f=48&t=34020&p=248192&hilit=spindle+off#p248192. If someone has done this it would help for you to chime in. It has been quite some time that I used a diamond drag bit and it was with a different cnc that used a handheld router and I just turned the router off. As you can tell from postings there is a problem with folks forgetting to turn the spindle or router back on when they want to use the cnc for endmills, ballnose and end mill work. |

I might be missing something (I have AR4 Pro+ and AR8 Pro+) but the only way to control the spindle is via the VFD (ie manually, not with software), so changing it with the software will do nothing, and if you rely on the software to turn off the spindle (and it doesn't) you are going to do some serious damage... maybe not with a diamond drag bit, but certainly with other attachments (drag knife, laser, pen holder, etc). Point me in the right direction if I am off the mark here, please. Allan |

When I tried creating a post processor that did not turn the spindle on, I got runtime errors. I didn't change the spindle speed only remove the 'turn on' pp command. Now I just set the VFD to '0'.

The Axiom G-code does allow the spindle to be turned on and turned off using an M code. However my coffee has not kicked in, and I don't remember what it is.
That said, I think in this circumstance, I would recommend unplugging the spindle motor which is the round 7-pin barrel connector. I don't think there's anything else in that connector (IIRC uses 3 pins for a 3-ph WYE and one for GND or Neutral). I think if you run the M command to turn the spindle off, it essentially stops the machine and it will not continue running code after that. However that could have been one of the CNC sharks which I also have a ton of here at this shop.
From a safety perspective, I would 100% at least disconnect power and turn the VFD to 0 (Another poster stated that the VFD speed on the I2R is not controlled by software, this is correct, it's only on-off) If you don't plan to use the spindle at all, I would suggest removing it and replacing it with an arbor more appropriate to your application.

For those who HAVE a laser, the J-Tech module has a toggle switch that you move between "laser" and "spindle". Moving it to "laser" mode WILL keep the spindle from coming on. Likewise, not moving it back to "spindle" mode will keep it from turning when you have removed the laser and gone back to running cutting files (been there, done that...fortunately, it didn't take me long to "remember"). The same action should keep the spindle off during drag knife or drag engraving operations.

For all i2R and Pro series machines...just turn the RPM dial to 0.00
The spindle will remain in neutral and no rotation occurs. This works very well for drag knife operations.

Change your "M03S0" to M05 and it will run the program without starting the spindle, in fact it will ensure your VFD does not turn on. you can also go to the bottom of your program and remove the M05 there as it is not needed. And yes I tested this on my AR8Pro. Just be sure to remove the "S***" command with the *** being your speed (IE:S100), meaning M03(start spindle in forward rotation), S100(at a RPM of 100).

And guys I would use notepad++ to edit the program as it has a compare where you can compare programs. here is the link: and it's free notepad-plus-plus.org/ |

Thanks for the post. I attempted to do this earlier, but I kept erroring out when using it. I hadn't got around to debugging it. Thurning the spindle to zero is fine, but this is an additional safety factor. ......visions of flying drag knives.
