Mistake #8: Cutting your hair with a CNC router So, this is actually a great and very informative video! Everyone having fun with my comment should at least vote a thumb up for the video, pls.
I have been running a machine commercially for 2 years now and still feel like I have no idea what to charge, some jobs go so easy and others a very difficult! I have learned that even though the machine is "doing all the work", learning how to use it properly and efficiently is also a huge undertaking. Thanks for the tips, probably a little late for me but hopefully others are smart enough to start here!
Excellent work. I'm retired and ordered a 4x8 CNC kit. I know it's an ambitious decision to build since I have zero CNC experience but, I figured what better way to learn my machine. I'm hoping that it may help diagnose machine issues that may arise later. This video was very informative and well presented . Direct, to the point, and no annoying music. Keep 'em coming.
Im ordering my cnc in the next week. And im glad ive been a cnc machinist for almost 20 years and a lot of what you said translates from machining steel to working with wood. Good advice. Cant wait to start making stuff
After my first year with my CNC I found myself in every mistale you mentioned. And I just had to go through it, like you said. Very helpful Video, thank you!
Hello!! Great Video and you nailed it in regards to accepting mistakes, and learning, then moving forward. I have been in CNC for 25+ years, and as a machinist I understand speeds and feeds, the hardest part for me is getting used to working with wood, (0.005" tolerance doesn't exist in woodworking! and thank God for Wood Filler ) I have built a hobby machine and am making signs. and such for friends and family. My hardest thing is putting a price on the fun side of it, which is the creating. Cutting is fine, but taking an photo and carving it is the fun challenge for me, and also the fun. I look online to get comparisons from others so I have been using that as a price gauge. So far I know have been charging less as I am very gratified to see peoples reaction, but as retirement is getting closer, I would like to figure out what are realistic charges I should be making. Thanks again and I will be watching your channel.
I've been a contractor in the painting industry for 40 years still doing the work only because I can't teach anyone what I've learned and tweeked sometimes I don't know how I even do it if you love what you do it's not work I love to keep learning the mind is a beautiful thing
Nice detailed video. I've watched a lot of CNC videos, as I hope to eventually add one to my shop. This is the first one that covered these types of issues. I'd be interested in seeing your CNC machines and talk about what you like and don't like about each.
Extremely well done without too much unexplained jargon. The cost calculations alone are worth watching this vid. multiple times especially since machine use time vs machine investment, Include dedicated work space, bits, materials for learning, final product material storage for material and possibly sound reduction in the work room. Then how does a retired non machinist price his/her time?
Problem of Running to slow. If you have a hobby machine it is not good to slow down the rpm cause the spindle is probably to weak, Same if you increase the feed rate. For beginners with hobby machines i would recommend to buy single flutes endmills, which allows to run them with high rpm and slow speeds with the right feed rates. This helped me the most
Broke my bit today. What can be great video? About bits. Its life time, different materials? Low end, high end, sime special ones? Thank you for your effort
Considering this. I want to say thanks to people who design, test and list every bolts nuts so beginners can start it out. Learning curve is painful, time and money costly
I must also agree very well done thank you…… I also have no experience, but I’ve always wanted to learn CAD and Cam So much that my kid got an opportunity for an apprenticeship where his license through the state now and has been machining for 15 years so I do have a great support system … but your video was awesome so thank you for the information
Excellent video for beginner in wood CNC milling. I make all 7 mistakes from video when beginning hobby CNC mill woodworking. I learn it personaly at hard way.
Hello, I'm a newbie and at the end of your video strangely I've though exactly the opposite of what you were saying. "Speed up your RPM or slow down your feed rate..." to avoid friction as you said in the case of running the bit too slow
If your bit is spining too fast the cutting edge gets round for the next cut before the machine moved enough to present new material so it rubs on the already cut surface creating friction and heat, when cutting speed is correct the heat is carried away by the swarf and away from the bit, you can see this better when cutting metal. Check out the temperature of your swarf you will find its a lot warmer than the piece your cutting. I think he meant moving too slow for the rpm on the machine.
I was a CNC tech at a university for a while and getting back into it now with a beefy 4x8 machine from Industrial CNC. If you get the chance to cover general feeds and speed with specific materials breakdown, that would be amazing! Also, Love these videos! Is there a way to help support?
Thanks for this video. I have been machining some UHMW and the bit was screaming...I thought I was pushing it too fast! Quite the opposite. Good to know!
That’s crazy, so they took away the IQ it seems and only have the Pro edition which has the Automatic tools changer, just the IQ should only be like $7,000, I personally would not start with a small desktop CNC like that with an ATC it would not save you enough time on your toolpaths. That IQ Pro is the upgraded version of mine. I don’t know why they took down the cheaper model, makes no sense. I would not of been able to afford that 15K CNC when I was starting out.
#1 Running a bit too slow I think needs clarifying a bit. You should have said feeding a bit too slow into the work, to me running a bit too slow refers to RPM rather than feed rate. Feeds and speeds is a very deep subject & to get things right is matching the rpm to the feed/travel speed so that chip load is correct & constant, morso in metal.
That was my thought too. Seems like advice on final mistake is backwards. If friction and heat are occurring, wouldn't it be because the trave rate is too fast and the RPMs (cutting speed) is too slow?
Thanks for sharing your knowledge im just getting into the cnc world and found this helpful, only complaint is would be nice to of seen a visual example when explaining what all the different drill bits do
what are your thoughts on the avid cnc line? I'm currently debating between the laguna IQ 2x4 and the avid PRO6060 5' x 5? This is my first cnc and I'm looking to grow it into a full time business but would like to spend between 10-20k.
I ran a shift at a cabinet shop that laid off their $10/hr panel saw operator and leased a $250,000 CNC router to cut rectangles out of sheet goods. They took their best cabinet maker off the floor to convert CAD to CAM, one line of code at a time, because they didn't want to pay for the good software. When they went out of business I took a job at a high-end shop on Maui. They cut everything on a panel saw.
Running the bit too slow creating heat is the same thing as a sawmill. Its creating fine dust, not cut sawdust. And as you say essentially rubbing. The bit needs to be producing chunks and clearing them out.
Great video! I just picked up a chinacnczone 6090 from a local auction. And want to incorporate this into my business I already have. But don’t know a single thing about this stuff. So this was a bug help. Still a long way to go.
Oil and grease don't "attract" dust, it sticks to them when they land, just the same as it sticks to your silicone spray. The only difference being that when it sticks to your spray you cant see it because it wets. Needless to say, your being able to see or not see something has no effect on its reality.
Good vid, was a bit disappointed when you didn't add straight flutes in with description of upcut/downcut/compression. Personally I prefer straight for finishing to remove all burrs.
I’m looking to get into CNC and I’m not certain which machine I should get. I sell (mainly) American Flags, cutting boards, and Adirondack chairs I make. I was thinking I could use the CNC to engrave/personalize the cutting boards and use it to cut out parts for the chairs as well as personalize the chairs, and use it to make higher end American flags out of walnut, maple, and Paduak . Which CNC would you recommend I get to accomplish those goals ? Thank you
Good advise here thanks. I am not new to CNC machining but I am new to the small machines. I recently purchased a Sainsmart 4040 pro and I am having trouble with chatter. I am cutting 1/4" Hickory and Walnut with bits from 1/8" up yo 1/4". So far I have had the best luck with a 3/16" single flute up cut tool. I am starting to think that the supplied spindle needs to be replaced with a heavier duty model. Any advise you can provide will be greatly appreciated.
Thank you for the video. Super helpful! Question - Can cnc machines use a 1/8” Bullnose router bit to de-edge and de-corner rectangle 1/8” polycarbonate? Would this bit run into the cnc table? Would the material need to be raised up off the table? Thank you for your time!
You speak with an understanding and enthusiasm, I respect that 👍. But give yourself another five years experience and you’ll blow it out of the water 👍👍👍. I’m retired now from teaching woodworking and Cnc for 21 years. Keep up the good work 😊
Great video and directions, I plan on getting a router over the next month. I am currently working with a co2 laser with LIGHT Burn. Do you work with lasers? I would like to see that video. SUBSCRIBED
CNC beginner here. my problem is that i don't know where to start. i don't want to buy a cheap machine that will not be able to do basic work and i do not want to over spend because i am just doing home, hobby things. the hardest metal i'll cut will be aluminum. and this will not be an everyday use of the cnc machine. question can a 800w, 24kRPM spindle cut Aluminum well? because i am thinking of a CNC 4030.
Great video. Nice explanations. The only thing I would comment on is the number 1 problem. It wasn't immediately clear what you meant by bit speed. There are 2 speeds, spin speed (RPM) and Feed rate. You just need to explain the difference between and their relationship. Liked and subscribed.
@@cutting-it-close just edit this video with the new section? Or add the new one and link to it from within this video. Do you plan on more detailed videos on actual machines?
@@cutting-it-close definitely some for the smaller hobby type machines. Like 3018 etc.. Some discussing how to do multiple cut designs (when you rough then detail).
great video. I have a Laguna IQ and it's worked pretty much trouble free for 7 yrs now. Unfortunately, I accidentally "Wiped the Cache" on the hand-held controller and lost my Pulse Equivalent settings. Apparently Laguna customer service isn't open on weekends :( Any chance you could tell me what the Pulse Eqiv. settings are in the controller of your IQ?? They should be what mine are supposed to be. Thank you!
Ok first off, I take NOTES, so thank you!!! Got y notes from this video! And now ,the UGH- I cannot tell you how many videos I have watched, how many notes I have taken, and speeds and feeds are always- always- always talked about....except...what they are, and how do you KNOW? Is there a guide that comes with each router that tells you what the slowest and fastest is for that router? Is it table/router marriage? Please...If you have already addressed this- can I have the link? My machine is coming, and I have written a notebook full of notes....watched a lot of mixed up, lost my place in line videos...SHEESH...and don't get me started on setting an origin...sighhhh whatever that may be. Sometimes, I miss books!
I've been working these machines for over 25 years professionally. I have cut wood, many plastics, and even aluminum. If you ever find an accurate link for that all I can say is I wouldn't believe it. There is no definitive speeds. I find the plunge rates, travel speeds, rpms, direction of cut, etc that you finally come up with is more of an art than a science and it is based on quality of cut, bit size, materials, capacity of the machine, and on an on. All I can suggest it to start from the "less aggressive" angle and work up than go from the other direction and probably break bits, have material move as cutting, etc. Take it slow and make a number of test cuts until you're happy with the results before committing to cutting the real piece. I still do that every time I do something new even after all these years. We're always learning!
Nice video. Thanks for the info. I am never sure of my speed and feed. I carve MDF which just makes dust. I carved some Maple with half inch end mill shaping cut. Chips flew and it was obvious that the feed was matching the spindle speed, but I don't see this with smaller bits.
I am thinking about getting a CNC to do things for our craft shows we go to. I do small wood items now but i do not charge for my labor. If i did my items would cost to much for people to buy at craft shows. Everybody is different but i charge enough to make our booth rental and for our supplies plus about $5 more. We do this mostly for fun. Everybody is different.
I fix 3 million dollar cncs for a living so I didn't go in blind on maintenance but the software side is where I struggle because of cost and or experience with it
@@kristopherhilton8065 I have found a few old cnc Bridgeport for sale. I know this is old technology but I’m especially interested in retrofitting to newer electronics without spending as much as a late model vertical mill would cost. I don’t mind doing the work
@@wewe365 I'm sure it wouldnt be too hard to set up. The coupling setup would be the hardest part and I would say use it as is to make the new couplers. The programming itself is real easy because you can just buy a cheap grbl controller online and throw on a few stepper motors of appropriate size then its just calibration.
Silicone based lube is not good if you want to use epoxy or spray finish on your woods. The finish will never stick . Stick to non-silicon based lube . Better yet, rig a pumping system to all your screws and bearings. Mobil Vectra 2 gets my vote for lubrication .
NEVER use MDF EVER! Look at the materials it’s made from. It’s Carcinogenic and it’s made from wood dust, formaldehyde and urea resins. You are breathing the fine dust in when machining, even with a mask. I won’t allow this stuff in my home unless it’s sealed with an oil base finish.
@@darrellsaturnbigfoot Problem is that spoilboards are usually made of just this type of material. There are also other materials that are made in equally toxic ways. OBF, Particle Board, LDF, HDF, Plywood, Melamine boards, etc. You have to stick to solid wood only, to avoid the toxicity and even then the dust remains and will still pose a problem in the long run, by increasing your chances of developing COPD (Chronic Obstructive Pulmonary Disease). You can't avoid carcinogens when you're a maker. You can just look up the most harmful carcinogens and try to avoid those, but at the end of the day, even your own body is a carcinogen, as it only takes a single cell that doesn't split correctly, in order for it to mutate into a cancer cell. Cancer isn't just caused by exterior reasons. It can easily be caused by your own body fucking up.
At about 4:00 you mention use of the half inch bit. I use a half inch bit in my cnc and its a hobby machine made out of HDPE and metal rails. Not sure if my experience is the same as yours because I run a half inch bit with ease. Perhaps its the type of cuts as well
How do up-cut bits tear at the material, if you use a chamfer bit for the paths first? Like leaving a 1mm chamfer after all paths are complete... Is tear out at the top a problem in plywood?
Hi Guy, You confused me near the end of the video regarding speeds. The goat screaming because its running too fast and screaming because it's running too slow. I'm guessing you meant to say the screaming is because the bit is running too slow. I just received the smaller desktop CNC with only a 1/8" collet and a 10,000 rpm spindle. I'll mostly be cutting wood and I've tried several different kinds. I tend to over test things to experiment with speeds, feeds and material. So, to my point, did you mean the bit is too fast or too slow? Thank you for a very well done video. You know your stuff and I will subscribe. Good luck with your other videos.
I want to get into using a CNC machine as a hobby to be able to cut wood signs letters metal wood metal signs and so forth. What would you recommend as an affordable machine and do you know if there is anywhere to get Training? I live in South Carolina.

can a 800w, 24kRPM spindle cut Aluminum well? because i am thinking of a CNC 4030.
Thanks for the great tips
Thanks....for giving valuable information
Awesome video. Is there a way the jig can be made without a drill press?
Great video. Nice explanations.
The only thing I would comment on is the number 1 problem.
It wasn't immediately clear what you meant by bit speed.
There are 2 speeds, spin speed (RPM) and Feed rate.
You just need to explain the difference between and their relationship.
Liked and subscribed.
@@cutting-it-close just edit this video with the new section? Or add the new one and link to it from within this video.
Do you plan on more detailed videos on actual machines?
@@cutting-it-close definitely some for the smaller hobby type machines. Like 3018 etc..
Some discussing how to do multiple cut designs (when you rough then detail).
great video. I have a Laguna IQ and it's worked pretty much trouble free for 7 yrs now. Unfortunately, I accidentally "Wiped the Cache" on the hand-held controller and lost my Pulse Equivalent settings. Apparently Laguna customer service isn't open on weekends :( Any chance you could tell me what the Pulse Eqiv. settings are in the controller of your IQ?? They should be what mine are supposed to be. Thank you!
What's the best CNC you can recommend for a total beginner for under 500?
Same question but with a $1000+/- budget... I’ve heard that not all CNC a can cut radius’s well.
Ok first off, I take NOTES, so thank you!!! Got y notes from this video! And now ,the UGH- I cannot tell you how many videos I have watched, how many notes I have taken, and speeds and feeds are always- always- always talked about....except...what they are, and how do you KNOW? Is there a guide that comes with each router that tells you what the slowest and fastest is for that router? Is it table/router marriage? Please...If you have already addressed this- can I have the link? My machine is coming, and I have written a notebook full of notes....watched a lot of mixed up, lost my place in line videos...SHEESH...and don't get me started on setting an origin...sighhhh whatever that may be. Sometimes, I miss books!
I've been working these machines for over 25 years professionally. I have cut wood, many plastics, and even aluminum. If you ever find an accurate link for that all I can say is I wouldn't believe it. There is no definitive speeds. I find the plunge rates, travel speeds, rpms, direction of cut, etc that you finally come up with is more of an art than a science and it is based on quality of cut, bit size, materials, capacity of the machine, and on an on. All I can suggest it to start from the "less aggressive" angle and work up than go from the other direction and probably break bits, have material move as cutting, etc. Take it slow and make a number of test cuts until you're happy with the results before committing to cutting the real piece. I still do that every time I do something new even after all these years. We're always learning!
Nice video. Thanks for the info. I am never sure of my speed and feed. I carve MDF which just makes dust. I carved some Maple with half inch end mill shaping cut. Chips flew and it was obvious that the feed was matching the spindle speed, but I don't see this with smaller bits.
I am thinking about getting a CNC to do things for our craft shows we go to. I do small wood items now but i do not charge for my labor. If i did my items would cost to much for people to buy at craft shows. Everybody is different but i charge enough to make our booth rental and for our supplies plus about $5 more. We do this mostly for fun. Everybody is different.
Thanks for advice
Very well explained! Thank you!
keep your videos coming!
Thanks Buddy You Explained it very well
very very helpful
I fix 3 million dollar cncs for a living so I didn't go in blind on maintenance but the software side is where I struggle because of cost and or experience with it
Do you work on older cnc Bridgeport mills ?
@@wewe365 no I work with newer ones. Grobs, fanucs, comaus, gehrings, ect
@@wewe365 if you have a question about anything I can ask the older guys I work with a lot of them started with those
@@kristopherhilton8065 I have found a few old cnc Bridgeport for sale. I know this is old technology but I’m especially interested in retrofitting to newer electronics without spending as much as a late model vertical mill would cost. I don’t mind doing the work
@@wewe365 I'm sure it wouldnt be too hard to set up. The coupling setup would be the hardest part and I would say use it as is to make the new couplers. The programming itself is real easy because you can just buy a cheap grbl controller online and throw on a few stepper motors of appropriate size then its just calibration.
Silicone based lube is not good if you want to use epoxy or spray finish on your woods. The finish will never stick . Stick to non-silicon based lube . Better yet, rig a pumping system to all your screws and bearings. Mobil Vectra 2 gets my vote for lubrication .
Thank you very much
Superb video, very informative - well done! Keep them coming!
MDF stands for Medium-density fibreboard, not "micro", right?
Right
NEVER use MDF EVER! Look at the materials it’s made from. It’s Carcinogenic and it’s made from wood dust, formaldehyde and urea resins. You are breathing the fine dust in when machining, even with a mask. I won’t allow this stuff in my home unless it’s sealed with an oil base finish.
@@darrellsaturnbigfoot so basically its like a cigarette.
Harder to light...
@@darrellsaturnbigfoot Problem is that spoilboards are usually made of just this type of material. There are also other materials that are made in equally toxic ways. OBF, Particle Board, LDF, HDF, Plywood, Melamine boards, etc. You have to stick to solid wood only, to avoid the toxicity and even then the dust remains and will still pose a problem in the long run, by increasing your chances of developing COPD (Chronic Obstructive Pulmonary Disease).
You can't avoid carcinogens when you're a maker. You can just look up the most harmful carcinogens and try to avoid those, but at the end of the day, even your own body is a carcinogen, as it only takes a single cell that doesn't split correctly, in order for it to mutate into a cancer cell. Cancer isn't just caused by exterior reasons. It can easily be caused by your own body fucking up.
At about 4:00 you mention use of the half inch bit. I use a half inch bit in my cnc and its a hobby machine made out of HDPE and metal rails. Not sure if my experience is the same as yours because I run a half inch bit with ease. Perhaps its the type of cuts as well
How fast are you running it?
Great video.. 👍
Like for "screaming"! Made my day )))
How do up-cut bits tear at the material, if you use a chamfer bit for the paths first? Like leaving a 1mm chamfer after all paths are complete... Is tear out at the top a problem in plywood?
love the details, i am currently printing my CNC, thanks for the heads up.
Howdy from Indiana! BQ ‘85. Whoop!
Hey Glenn can I introduce you to Tom from the comment above.
Whoop!
Love your videos! Keep it up👍
7. How to charge? Well the market decides that, if you don't have enough, work go cheaper, if you have more than you can handle, raise the price.
Hi Guy, You confused me near the end of the video regarding speeds. The goat screaming because its running too fast and screaming because it's running too slow. I'm guessing you meant to say the screaming is because the bit is running too slow. I just received the smaller desktop CNC with only a 1/8" collet and a 10,000 rpm spindle. I'll mostly be cutting wood and I've tried several different kinds. I tend to over test things to experiment with speeds, feeds and material. So, to my point, did you mean the bit is too fast or too slow? Thank you for a very well done video. You know your stuff and I will subscribe. Good luck with your other videos.
Awesome video!
A nice video, but are you using for lubricating garage door lubricant only? Don't you need to use grease for ball screws and oil for linear guides?
Hi, It's great, I'm a biggener what cnc machine you recommend for me
Great Job!
I want to get into using a CNC machine as a hobby to be able to cut wood signs letters metal wood metal signs and so forth. What would you recommend as an affordable machine and do you know if there is anywhere to get Training? I live in South Carolina.
