Common CNC Router Project and How To Avoid Them
Вставка
- Опубліковано 27 чер 2024
- In tis video, I show several mistakes I made on a CNC router project. Mistakes on CNC routers and various CNC machines is largely the cause of a forgotten setup step. Here, I explain some of these common mistakes as I made them and how to avoid them.
Because there are many things we can miss during a setup, you want to use a checklist to confirm everything.

@IDCWoodcraft thanks for all you do. have tried to sign up for the checklist but never received the link. it acts like I need to purchase your design bundle in order to receive the link.
I've used the BEAST BIT on red/white oak, walnut, hickory, and cherry and the BEAST eats through it like butter!! Best bit ever made!!!
vabearhunter401, right on brother! Happy to hear you like the BEAST.
Thank you for the checklist. I plan on using it to help train my grandsons as WE have made mistakes, so they are a little CNC shy.
techturtle1964, no problem brother! I'm glad you got the checklist and I'm looking forward to seeing what you and your grandsons create! Happy cncing!

Nice save Garrett, but I am not ready for the vacuum system. Blue tape and super glue for me.
jimpalmer1944, that is a great method too brother!
Mistakes are things you can’t fix!
All I saw were brain farts!
Nice machinE!!!!!!
Lol, that's about what I did!
All least I can laugh at it
Sometimes it stinks to be human. When mistakes are made sometimes the real creativity happens.
kevinrich4637, true that brother! I couldn't agree more.
By the way, I got my bits and thanks for the candy and the great light. Still working on my infinity 32\32 pro. Installing my vacuum ,got a win . Did some carving with it ,God it put x carve to shame. Not bithin😢the xcarve has been a great machine, hate them belts. Again thanks
paulrcreech7731, you are so welcome brother! Glad to hear you are getting your new machine set up. Happy CNCing!
Hey Garrett I think your pretty awesome and I have purchased from you ! Do you sell a 1/4 "muscle chuck for the dewalt router?
velcrodreams178, Not yet! I have been working with muscle chuck to provide more options for machines like yours so thanks for your feedback on that one. Ill keep you in the loop!
@@IDCWoodcraft thanks Garrett your the man!
You can easily determine which side the bit will cut by looking at your green start point and the path direction arrow. Imagine you are standing on your start point looking in the direction of the path arrow, right is right, left is left.
butchmiller2451, very good point brother! I couldn't agree more.
That was a lot of mistakes! One mistake was not recognized as a mistake but it took 3 attempts to get it almost right.
That did convince me that vacuum tables are not for hobbyist's! Way underpowered and way too many reasons it will loose vacuum. I did mess with one for a year or so until I found it it cost less than a new anchor for my boat. Too many failures hours into a project where the vacuum let go due to porosity/cracks/knots in material after machining into it. They do consume up to 4 times the power of the entire cnc machine also. I found simple plastic pipe pegs and wedges or cams made from scraps were a quick couple of taps and material is secure. The video also showed only 1/2 the table was on so if all 4 zones were open it would be 1/2 the hold down pressure and 4 times the problems.
One item that wasn't called a mistake is actually a common mistake. I think people visualize from the top down creating the challenge.
Have a look at commercial machines. You will find their tool setters are in fixed locations. They reference the only known reference the bed. All other references are floating in space somewhere. Using a table saw cutting a 2' square from a 2.5' x 2.75' scrap with 2 jagged edges do you set the fence to 2' or set the fence to 0.5' and guess the jagged part?
To explain lets take a point in space above the bed, you pick it don't tell me. Your machine now referenced depth from that point. It doesn't know 3/4" down is the bed it only knows the point in space and you assume its about 3/4" above the bed. Its like closing your eyes and holding your finger out, that's the point. It references nothing. That is the accuracy of a point in space! Or in this case the reference to the surface of the material that is not perfectly flat and not perfectly parallel to the bed. The bed however is a known point, 3/4" above it is exactly 3/4" above the bed 100% of the time. This is a know reference vs a point in space like the fence on the table saw its known the tool is 2' from the fence.
So lets say your material thickness varies by 1/4" for the example of a 1/2 material (variation of 3/8 to 5/8"). If you reference the surface at a thin point your cut through will dig into the bed 1/8" or lets say you got a high point and it doesn't cut through at all. This is a point in space reference. If now you reference the bed and instruct the machine to cut down to -0.1mm (0.1mm below the bed) it don't matter if the material is 8" thick (well with the model that may be a crash) or 1/4" thick the tool will cut through 100% of the time and barely touch the spoil board. Its also know if you cut a pocket into the material leaving 1/4" below it that it is exactly 1/4".
In most machines there is a known reference, table saws its the fence. Thickness planers its the bed, drum sanders is the bed. Its never the material.
The cut through mistake exposed another issue. It exposed how much the bed reference (and surface location) can change with vacuum pressure changes. This changes the bed reference from a known to an unknown. Due to the 3rd cut through attempt partial failure it could show the foam doesn't evenly compress or the bed is not surfaced.
One other consideration! Your making a picture frame 1/2" thick, you machine the pocket out of the back then flip it and machine the fancy frame design. So if you use 3/4" material for frame 1 and 7/8" material for frame 2. What is your final part thicknesses if you use surface reference or bed reference? Both bed references are exactly the same finished part. The 2 surface referenced are 1/8" variation in final thickness. Surface reference to be sort of close you will have to redesign the model for each stock piece if the stock thickness changes. Bed reference 1 model fits all as long as the model considers the stock could be thicker.
Two sided machining is a bit different but referencing the bed is still best but a few things to consider, it may be easiest to reference the surface on side 1 and bed on side 2.
Calipers are an invaluable tool but you won't find any in my shop! I found they induce many errors by forgetting to zero them constantly. My guys carry standard inexpensive tape measures. There is rarely a need to know to 1000th of an inch the thickness of wood, if you use the bed as the reference you only need to know the stock material is slightly thicker than the final machined thickness. 1/8" accuracy is the most ever needed. Calipers are used in the design stage mostly.
Calipers are also tricky with wood as their thin fingers are like scissor edges and do not accurately measure slots or holes. The flats work for thickness if you don't squeeze them tight.
3dtwerking324, glad to hear this video helped you brother. Thanks for sharing your perspective on so many different issues you have come across. As for your questions, these are 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!
Garrett,
I watched as the "Beast" roughing bit was cutting out your design and was thinking about how expensive it would be to replace the vacuum table if you accidentally cut too deep. I know the tool setter helps, but are you scared about damaging the vacuum table surface? Also, would it be better to select 'Machine Bed' for the Z Zero Position setting in the Vectric software? That way your bit is limited in the negative Z-Axis direction.
Thanks for all the videos you create.
rogersecura5181, good question brother! Using a roughing bit like "The Beast" certainly calls for caution, especially around a vacuum table. It's good to have a respect for the potential costs of a slip-up. Even with tool setters and precision equipment, the risk is always there. Many CNC operators do prefer setting Z Zero to the machine bed for operations where they fear they might cut too deeply; it can act as a safeguard against plunging too far and damaging valuable equipment. It's all about finding that balance between confidence in your setup and healthy caution. Remember, no question is too small when you're making sure you've got everything dialed in just right. Keep up the curiosity, and stay sharp with your projects brother!

I would highlight that you have not cut full depth like previously when it moved. Most likely would’ve not moved if you would’ve cut as originally planned😅
ziggim1262, good point brother! I couldn't agree more.
Garrett, what happened with that monport laser?
Rob, I still have and use it here in the shop brother!
Are those the correct zones, and turn on before zeroing?
A good catch but yes, they were the correct zones
Now that machine is fast
paulrcreech7731, I couldn't agree more brother! This machine is a BEAST!
valves were off?
marshallharrington4727, good catch brother! I couldn't agree more.
Shouldn't you have turned on your vacuum before probing your Z ?
AcrylicMemories, you bring up a very good point with that one brother! And excellent catch!
