- You put a lot of money into your CNC router, so care and CNC machine maintenance is important. This video tutorial shows you how to take care of and repair the Makita trim router (keep it from burning up) on your CNC machine.
One aspect of CNC router (or any CNC machine, like CNC lasers and plasma cutters) that we sometimes overlook is the trim router (spindle), or the machine that actually turns the CNC router bit. Sawdust or metal dust can get into the machine housing, causing cooling air blockage. This will cause the router to overheat and burn out.
It is good to open the router once in a while to clean it out and check the brushes. This video shows you how to take apart (disassemble) the Makita trim router, check it for problems, replace the brushes and repair it, clean it and then put it back together.

Now this is cool. Others, who demo the CNC, have been dropping the ball here. Look for copycats soon. Sharp thinking.
Hey William, thanks brother! I'd be flattered to see others following suit!
Garrett, Just a note or disclaimer if your Router be it a Makita or Dewalt or other manufacture and it is under the manufacture warranty period usually 1 year do not cut the name plate (sticker) that is used as a security device to show if the internals have been access by other than authorized service representatives. It will void the warranty. Also prior to inspection of the Brushes for the Makita RT0701C Router it is a good ideal to have a new set of brushes on hand. The brushes are just carbon and can break easy if dropped or if they fall from the table to the floor. Part number is here for all on the Makita : CB408 CARBON BRUSH CB-408 (195008-8). Compressed air is your friend to blow dust and debris from the internals be sure to set air pressure to no more than 30 psi. Safety note wear the appropriate PPE (Personal Protect Equipment)
Great Video by the way as there are many People out there that have limited knowledge and know how or do not or have not ever serviced or repaired their tools. Remember rule number one! Garrett stated it unplug / disconnect the power source from power tools, hand held or small / large machine format before servicing it takes only seconds for an injury and can take months to years for the injured body part to heal if the damage to the flesh is not too great. BTW Makita has great support on their website with a full parts break down of their tools in a downloadable PDF.
Jwar, these are all great points brother! You are totally right about the brushes. I am sure that this will help our brother and sister CNC'ers out there to know the inside tricks to servicing their routers!
Thanks for the videos. I have to admit that you brought back some good memories when talking about taking things apart as a kid and especially when you mentionned the cash register. That reminded me of when, over 40 years ago, my dad brought home an electro-mechanical cash register he found in a dump so I could take it apart and I agree with you that it was one of the most complex piece of engineering I had seen at that time.
Andre, you're so welcome! That register sounds like a blast to take apart, especially as a kid! Sounds like a good memory to hold onto brother!
Now I know I can check my router for issues and how to do it! Nice!
Jeff, that is exactly what I wanted you to know out of this video. Good to hear!
LoL so.... Last week I went out and picked up a NEW router because mine was starting to perform poorly and sounded like it was going to break.... I did not know about the brushes... I now have two Mikita routers that work exceptionally well...
Thank you for this video!
RussReid, you are so welcome my friend.
You can get brushes, can you get switches and speed control pots? Looks like you clean it every week. Good job. It's a rare thing to teach at all levels.
Ron, I would recommend reaching out to Makita about replacement parts, I know you can get brushes though!
Glad you're bringing this important topic to our attention, Garrett. Two comments: 1). I don't particularly like the idea of using the router mount as a bench. In lieu, you could set a block of wood or small wooden box atop your table beside the mount to work on. 2). It's relatively a simple task to replace bearings, so rather than recommending tossing the router if they require replacement, why not simply change them out?
Hey Marty, both are great points. You could definitely use block of wood instead of the router mount and you absolutely could change out the bearings on the router too. Both are great suggestions! Thanks for your insight! Keep up the good work my friend!
Great video. I thought my makita was done for, but it just needed new brushes. Thanks!
MagicianNYC, no problem brother glad I could help!
Thank you! Always great seeing your how to videos!
Reida, you are so welcome my friend.
appreciate the superb video on maintenance for the makita router. it's always a pleasure to watch your video's. thanks!
Ron, you're so welcome! Glad it was helpful my friend!
Great advice Bro. Maintenance is very important to keep everything running good. I made a CNC Runtime Log, which I use to keep track of each project's running time, speed, & material. Every 100 runtime hours, I do minor maintenance (clean-out & inspection) & every 500 runtime hours I do major maintenance (clean-out, inspection, worn parts replacement, and lubrication as necessary). I have had my CNC since 2017 and have not had any issues with the routers & spindles by following this routine.
Alp, that's a great maintenance schedule! Wow, since 2017? You're taking great care of that router of yours my friend! Keep up the good work!
Your timelines between minor and major maintenance sound logical to me. Thanks for sharing them with us. I also vacuum the router's upper ventilation ports and conduct a visual inspection of the V-wheels after each project.
@@ApexWoodworks Your welcome Marty. Being a Recreational Aircraft Pilot, I patterned my CNC Maintenance Schedule after FAA Aircraft Maintenance Schedules. Thanks for pointing out the additional things yo do. I vacuum or blow out the router's upper ventilation ports once a week, as well as the track slots. I also run the x, y, & z axis's slowly across their length once a week, while gently holding a cleaning cloth against the wheels to remove any caked-up sawdust. I also check the tightness of all nuts, bolts, & screws during the 100 hr maintenance. While my all this may seem like a pain, I am a firm believer in the old adage 'an ounce of prevention is worth a pound of cure'.
Good information... I put a used sock on top of my router as a extra filter keep it up brother
Hey Dan, thanks and great tip!
Garret, I have a Nest security cam above my 2 Shark 100 machines.
I just dealt with a router that burnt out and I have it on camera if you cared to utilize the snippet I can send it over.
Thanks for everything you bring to the table to teach us.
Chris, wow caught on camera! Sure thing, send it over to my email, I'd love to see it. And you're so welcome brother, glad to help!
I just sent it.
Thanks so much for showing us how to do this!!! 👍🙂
Joe, you're so welcome brother!
I want to point out something I see here on your armature where the brushes ride. The dis coloration there. At some point if that is not cleaned off the brushes will start to arc and your router will not run correctly. You need to get apiece of fine emery paper and sand that are until it looks like all of the black is gone.
Jeff Peters
Thanks Jeff. Yes I'm aware of that. And I forgot to say something about that in the video. Thanks for reminding me
Good catch!
Before reaching for any abrasives to clean the armature, I'd recommend first using denatured alcohol. If that doesn't work, then a cloth dampened with lacquer thinner. Be very careful not to get any solvents anywhere other than the contact points, for fear of degrading the coating on the wires in that area.
Those thinners very flammable I my self would not use any if those
Ju
I have 2 Bosch 1617's. One I had for a while. The other I bought new for the CNC Router. Haven't had to service either one yet. Like having the backup though. Taking things part is fine, as long as they work when you put them back together. That's when I wish I didn't fix something that wasn't broken.
CNC Programmer, right on! It's nice having a backup just in case. I totally agree though, every now and then that saying "if it ain't broke don't fix it" does have some truth to it! lol
Awesome info, great tips on maintenance, it's something we all overlook in every aspect of our lives.
Once agan, thanks for the reminder. Off to do the same 😁😁😁
Roy, thanks brother it's my pleasure!
Thanks for the information my friend.
Jess, you bet! Happy to help!
It's funny that you mentioned about taking things apart. I used to (and still do) just to see what makes it work. Re-assembly can sometimes be a real challenge. :-)====
Ozguzzi, you know it! Taking it apart is easy, but that reassembly and not losing anything can be a real pain!
@@IDCWoodcraft Most every body has a cell phone The best thing to do is to take pictures of what you take out before and after the item is out .that way you can look at the picture to help put everything back where it belongs.
Great video. I'm cheap. For about 10 years I been using a harborfreight DRILL MASTER 2 HP 1/4 in., 3/8 in.,1/2in., Fixed Base Router. I clean the dust out of it too. They have some cheap trim routers to. I have have a 1/8" collet so I can use 1/8" rotary file bits.
Karen, thanks! Harbor Freight has some good stuff my friend, I find many great gems there!
Great Videos, very instructive, Are you able to use 1/8 bits in your Makita? I see you talk about a set of Collets for this but I could not find the link
Manolo, you sure can brother. Here is the part you need: www.idcwoodcraft.com/product/collet-1-4-to-1-8-adapter/
This is an excellent video - thanks as always! For reference purposes, how many hours do you figure you might have on that router? That way I'll be able to figure out when I might need to do this and also estimate how much run time we might get out of our brushes. Thanks!
Hey Michael, I think a good rule of thumb is to check up on it every 100 hours of run time. You may be able to get more than 500 hours of run time out of your brushes if you take good care of them brother!
Easy !! Get a spindle!!!
Tidesrollin, also an option brother!
Thank you sir. Do you have to get your router level again after putting it back in?
Shirm, yes you'll want to tram it when you put it back in!
Garrett could you explain what you mean when you say this is a line on your .125 drill bit ( No PecK to .85") Thanks Jeff
It means you do not have to use the pecking cycle up to .085 in deep. You can just plunge. Pecking takes more time because the router pulls in and out
Great video thanks.....I have one question though? How long can you run these makita routers continuously?
Jonathan, this is a great question brother. I don't have a great answer for you since I haven't fully pushed it to it's limits. But, they can run for hours without any issues. I'd recommend reaching out to Makita directly if you're looking for more precise numbers my friend!
In My early days My machine started to stop by itself in the middle of runs . i thought i had computer problems. it was suggested that the brushes needed replacing and were starting to arc and that was upsetting the computer. Sure enough they were very low , replaced (for the first time) them and all was fine . cheers
Peter, I'm glad replacing them did the trick brother! Cheers!
Question about the drill bits 1/8" 1/4" dia drill bits what happens If the pegs you buy are just a little bit larger dia than the1/8" 1/4" and won't fit in the holes. Do you use 1/8' holes for the tool path Could you show us what the set up is for the toolpath?
Resorter66, you'll use spiral drilling to get the hole size you want. You can't do spiral drilling with a drill bit though, you'll have to use an endmill. I recommend you check out this video on drilling holes, I think you'll find it super helpful. Here's the link → czcams.com/video/e7xMpL-0F_A/video.html
Thanks for this. Do you recommend putting any oil on the bearings and if so, what type of oil?
The bearings are sealed bearings, no lube required. Oil will just make the sawdust stick, and make a mess.
@@ozguzzi thanks for letting me know.
MakerDan, ozguzzi is totally right! No oil needed my friend.
Is there an estimated time in hours the Makita trim router will run before replacing the whole unit? Thanks for the video! Very informative.
BrickMaster, that is a tricky one to answer brother. It all depends on how hard you run it the environment it is in.
hello..could your Makita RT0701C make a long run on more than one hour? Thank you!
Kudennnnnnn, you sure can brother! Plenty of CNCers do it.
@@IDCWoodcraft thank you very much
Pretty sure this will not apply to my 8.7 HP spindle head. The video is perfectly timed though. I'm starting the process of tearing down my machine to transport it across the country. This reminded me to take the time to do preventative maintenance I have been putting off in favor of production
Hey Eric, definitely make sure to do the preventative maintenance on that 8.7 HP spindle! Gotta keep that bad boy up and running right! Good luck on the move my friend!
My problem with the rotor is the speed wheel keeps turning by itself. Any ideas how to stop it changing speed
Paul, that shouldn't be happening brother. Consider reaching out to Makita or your router brand company for a replacement part.
So my router is doing a strange thing since yesterday, maybe you got an idea. It wants to ramp up in speed, then slow down, then speed up then slow down, pulsating. I changed out the carbon brushes thinking that might be the reason, but that didnt solve it. I took it apart and it was actually really clean yet, so dust wasnt the culptrit. Now to mention, I did use a 1" surface bit and did a large chunk of oak yesterday and wonder if maybe the router overheated/got too hot. You dont think I fried it do ya? needing to buy a new one?
JCraftvfx, I'm not too sure on this one brother. It sounds like it very well may have overheated. I'd recommend reaching out to longmill directly and seeing if they have any tips/tricks for you troubleshooting. Here's a link to their contact page: www.vectric.com/support
One note, in all cases everything was good so never got to see what not good looked like and how to clear the saw dust out if found.
David, you're so right you may not need this for a while! Just an extra little tool in your toolbox if you ever need it!
Hey Garrett! I'm new to your channel, and am slowly making my way through your excellent videos.
Me being a total beginner, would you mind explaining why this thing 7:04 is named "brush" (English is not my first language, and a brush to me is something with lots of bristles...).
Thank you so much!
I think they call it that because the armature rides across it. It's a term that has been used ever since I was learning mechanics years ago
@@IDCWoodcraft Thanks!
Brush can also mean to touch something lightly and gently as when someone brushes past you. These are brushes because they make light and gentle contact with the armature.
How often do you do this maintenance?
Brian, if you use your machine daily, I would say every 6 months or so. If you don't use a dust collection system, you will need to do it more frequently.
or the Harbor Freight Bauer like I run...... LOL. FOr $74.00 you can grab an extra one to keep on hand. I always take my shop vac to the top of the router. I have seen a video of someone that put a sock over his. I don't know how much heat that would introduce into the system. I have not done that.
Jack, great point! Harbor Freight has some good stuff brother! I'm not too sure if I'd be willing to put a sock over mine, I'd worry about that heat over time like you said my friend!
Where did you bought makita replacement brushes. Amazon brushes are easily burnout.
Skyone CNC
I'm on my second Makita palm router. Both have overheating problems. My old one stays cool but somehow these new 701's get hot fast . Makita tech support is of no help. I would not recommend Makita now .
JoeyGonzo, you really work out your makita brother! Consider upgrading to a spindle in the future.
Moi j'ai acheté une AMB elektrik ! en panne au bout de 18 mois de marche normale, l'électronique n'est pas réparable à cause de la résine couler dans le bloc électrique. La pièce coute 120 € et il faut envoyer la machine à amb = 250 € de facture. Kress a été acheté par AMB...FUYEZ.
Salut, thanks!
