Spindle Upgrade... You MUST Add A Pause (dwell) Command! [CNC Router]
HTML-код
- Опубликовано: 2 фев 2024
- If you have found the best spindle for your CNC router for a spindle upgrade, one thing that must be done is adding dwell to your post processor. In this video, I upgraded my Longmill MK2 from the Makita trim router to a spindle by a company called Pawn CNC (PwnCNC).
When you upgrade your CNC router to a spindle, you must add a brief pause (dwell) in the G-code program to allow the spindle to reach its RPM. Without this pause, the spindle can start a cut before it is fully up to speed, which can break router bits or damage your project material.
In this tutorial, I explain how to modify your post processor to automatically insert a dwell command when the g-code is written. It will insert the command immediately after the ‘spindle-on’ command (M3). This ensures your CNC router waits for the spindle to speed up before commencing the cut.
Using Vectric design software as our demonstration platform, I'll guide you step-by-step on how to locate and edit your post-processor file to include the G04 dwell command, which is the g-code that initiates the dwell. For those not using Vectric, the principle remains the same: find your post-processor file in your directory and apply these adjustments accordingly.
The dwell command (G04), followed by "P" and a numerical value without a decimal point, specifies the pause length in seconds.
What the dwell command line should look like → G04P5
This command will pause the CNC router for 5 seconds

NOTE: It is recommended to upgrade benchtop CNC routers to the 65mm unit, not the 80mm unit

Even if your not going to upgrade. It will still be a good idea to put the dwell command.
deronthomas7904, thanks brother! I completely agree with you on this one!
Great video, Garrett. I upgraded to Version 12 this week. This is what I found in the file when I opened post-processor commands. "M3[S]"
"M0(MSG, Click 'Continue' when the spindle is up to speed)". Original series: Onefinity Woodworker. I'm in the process of installing the PWNCNC plug-and-play in the spindle system.
fodge69, you are so welcome my friend. It sounds like you are getting up to speed with your new spindle brother! Congrats!
Another great video Garrett! Love your bits my friend.
nwnimbleman3576, thanks again my friend! I'm glad to hear the bits have been treating you well so far over there! Happy cutting!
Great walk through and so easy to follow tks. Garrett
Sam, glad it was helpful brother! Happy cncing!
Great tip. Thank you
FALCON390CNCWorks , you bet brother!
Thanks again for a great upgrade!!!!!
Jeffnunnas, you are so welcome brother.
great just what I was needed and on time thanks
jonzaharescu, you are so welcome my friend.
Great information
Glad it was helpful brother!
Thank you Garrett! I just installed my PWNCNC spindle last week and I am tramming it right now. This video and the information was very helpful to avoid breaking an endmill or damaging a project.
brianwade, you are so welcome my friend! I am excited for you to get your new spindle all set up.
Excellent video, Garrett!! This will be very helpful to those of us that have spindles.
Thanks for taking the time to make this video. ❤️👏👏
Joe, you're so welcome! I'm glad you enjoyed it brother!
Thanks for sharing. 👍
wcgraham3609, you're so welcome! Happy cncing!
With the g code that I have used in the past, "G4 P5" would dwell the machine for one-half of a second. For a dwell of 5 seconds, we would use "G4 P5000". Thanks for the heads up!
jeffteeter501, so glad to hear this one helped you brother!
very helpful, thank you!
stereorich, you are so welcome my friend.
Thank you! I love as you learn things, you are so excited to pass that knowledge down to us.
My Avid CNC is in milli-secs, so I had to Pause/Dwell for P5000. I quick reference showed X5 was for seconds, but that did not work for me, so I will stay with milli-secs. This video also showed me how to automatically start my dust collection by adding an M7 before the spindle start and dwell. This also gives the dust collection time to get up to speed. The other outlet is controlled by M8 so I could connect something else like a light. There was an M9 already at the end of the G-code to turn the outlets off.
Note this does not replace the initial spindle warmup cycle, which I personally need to be more vigilant about doing.
techturtle, that is some great points brother! Sounds like you have your AVID fine tuned sharp.
as usual great video thanks for your input into this subject
Barry, you're so welcome! I'm glad you enjoyed it brother! Happy cncing!
barryjefferies, you are so welcome my friend.
Nice Shirt!! And thanks for the dwell instructions!
jeffjaekel2558, Thank you for the compliment! I'm glad you found the instructions helpful.
Another advantage to having a spindle, if you have the PWM setup, is you can control the speed through the gcode. So if you have the database, it will set the speed automatically and not have to worry about turning it down on the router. Now I have my trim router connected with a solid state relay to turn on with the M3 command.
tomswoodwork, very true my friend. Having direct control like that is definitely a game changer.
Nice video and very useful. It should also be noted that all VFD will have a command that defines how quickly the spindle accelerates (spins up). You could use that command to shorten the dwell time.
cliffordcosta, so glad to hear this one helped you brother! Great point regarding the VFD and spinup times. I couldnt agree more!
Excellent bro, excellent I’m looking forward to mess around with My post processor. There are a few things I want to change in any way I will open up some different ones. See what can I come up with for my machine very excited, looking forward, writing my own post processor. cheers, Ziggi from Australia
ziggim, so glad to hear this one helped you brother! Happy CNCing my friend.
Excellent Video Garrett. If you're using Gsender 1.41 there is a switch to add a delay if you're using a spindle.
waldronnewell, good point brother! Glad to hear gSender has this feature as well.
This is a very nice video and good information. One thing to note is that I am using Mach4 with the Ethernet Smoothstepper. For this setup the G04P command needs to be in milliseconds rather than in seconds. For me the "P5" would have to be input as "P5000".
me-qg2mt, good point brother! Glad to hear you sorted it out with your ethernet smoothstepper too.
I like to Plaque that you made about 3 years ago of the JEEP but it only showed you cutting it out and not how you designed it. Could you do a video about how you designed it because my son has an old WILLY that he drives and I would like to make him one. I have a number of your bits and they are, WOW, at cutting. Thanks for all the help I got from your videos.
Karlriley, that is a great video idea brother. First thing I have to do is find the file after so long! Thanks for the video suggestion brother.
I've gotta say....Your videos are spot on great topics for CNC'rs. I've got a new Legacy 3x5 Gen 3 Pro......I absolutely hate it when the bit hits the wood before the spindle is up to speed.
I've been adding the G-code manually to the file.....and sometime I forget. I had no idea I could make this happen within Vectric. Just for your spot on video....next time I need a bit....I'm gonna pay you back with an IBC purchase!
Navigator, glad to hear this one helped you brother! Im so glad to hear that the vectric settings helped remove this manual process for you. Happy CNCing my friend.

I watch and read everything I can get my hands on involving CNC routing.
Your videos really scratch all the missing information. Sometimes I'm way ahead of the content in your videos, then other times, I've no idea what you are talking about. So thanks for keeping us on our toes.
When I bought my router, it came with Vectric V Carve Pro. When I started the program it moved instantly. Then when I upgraded to Vectric Aspire, when I started the program, I noticed there was a pause of several seconds.before the axes moved. Didn't know why, didn't care. it worked fine. Giving the spindle time to get up to speed seems like the most sensible reason.
CNCProgrammer, good point brother! Glad to hear this helped clear some things up for you.
Glad you finally installed your spindle. Now are you going to do Badger, Beast and Hog video?
KevinRich, it is in the works brother! I will keep you in the loop.
As usual super video and that I you so much for this… do you plan to do some additional video on how you replace your Makita router showing us the different connection to the LongMill electric board and how you installed the new spindle ? Many thanks in advance
Jean, thanks my friend! I will absolutely add this to my video to do list!
This video was very helpful with the longboard but now with the super longboard it seems to be ignoring the pause and is instead going straight to the cut as it ramps up,come back to this vid to double check I didn’t have something in wrong but can’t seem to figure this out now.
You will want to call longmill on this
Ok so i am a newbie idiot,I figured it out,I had simply forgot to switch back to normal mode in g sender after having a ran a laser project a few days ago lol,guess i should be using the machine more so i that I build on all the needed habits to be a good operator.
@@IDCWoodcraftThanks for the reply,I already figured it out,was my own fault,I forgot I had use the laser a few days ago and forgot to switch the settings back in g sender. Thanks for all you do for CNC world
Am ,awaiting delivery of my spindle.
Gary, thanks for checking in brother! I'm looking forward to you getting it in hand and seeing what you think!
I have been starting my file. Pausing . Letting my spindle cut on then resuming 😂
ballistictorpedo, that works too brother! Hopefully the gcode in this video gives you some better tips on spindle startups.
Very informative. I don't have a spindle yet, but the info will be useful in the future. I noticed in gSender that you can add program start/stop instructions. Would this be an option without modifying the pre-processor? Just curious.
cablsurfin, great question! Adding program start/stop instructions would work great as well brother!
Did u get the 2.2 k 110 v water cooled?
25cobrabyte, I tried out both the 1.5 and the 2.2 V and they are both great options brother!
Thanks, Garrett I have a spindle and I need to do this. I thought I saw in the Vectric setup that there was a place to set a dwell without modifying the g code. Also how did you get the software to start the spindle? Did you wire the old spindle wires into the VFD?
jimbembinster, getting everything set up in the controller and the software is a bit tricky brother! Your best bet is to reach out to your machine manufacturer for your specific machine and controller.
Cool. I have to ask about 2 specific longmill (actually scienci) features in gsender. They have a delay after spindle on setting in setup and they allow inserting gcode before every job. I get that doing it in vectric probably touches more followers, but wouldn’t doing it in gsender make my past jobs adopt the delay also?
Any idea what the pause value is in the gsender pause feature? I read documentation and can’t find it, I know I can copy your gcode settings for the run before method.
shughes599, This one is a little tricky to walk you through over comments my friend. I recommend joining Kate and I for our live sessions we host every Wednesday evening at 8PM EST. We should be able to help walk you through it then brother!
Hi. At 07:27 just below where you inserted the Dwell command there is already a Dwell command !!!! Could you please explain ?
Hi ice. Probably because I inserted it when I was practicing for the video and forgot to remove it. Duh... Why didn't I see that?
@@IDCWoodcraft Thanks a lot for the clarification 🙂
What if you're using a diamond drag bit which doesn't need the spindle to start turning? Does setting the speed on that bit in the database to 0 prevent the spindle from turning? And will that dwell command still be in there, actually being useless in such a case?
PowerPc, This one is a little tricky to walk you through over comments my friend. I recommend joining Kate and I for our live sessions we host every Wednesday evening at 8PM EST. We should be able to help walk you through it then brother!
So is the post processor is in each file that is used on the longmill? In other words, all of the files generated from Aspire and used with the Makita will need to be updated?
Hi Dan great question. Yes, All old programs that ran with the Makita will have to be re written with the dwell command
The spindle order page asks which controller kit will it be hooked up to. Not sure what the answer is.
kevinpage2730, it all depends on your machine brother! Your best bet is to reach out to your machine manufacturer to determine what controller you have.
We are in the process of setting up the MK 2. We have on order the new super long board. Is this pawn spindle compatible with the new super long board?
PaulSchuster, that is a great question brother. I recommend reaching out to longmill directly on this one my friend. They should be able to give you a little better guidance than I can on this one. Here's the link to their contact page →sienci.com/contact-us/?ref=IDCWOODCRAFT
I found their video on the super long board They were demonstrating it with a mk2 equipped with a spindle. So I suppose the answer to my question is it has those capabilities and is compatible.
