I suggest testing front and back tram BEFORE left to right tram. Because if you need to shim the spindle mount or Z axis mount itself, you're going to have to redo left to right tram anyway since you loosened the Z axis.
One of the easiest and most accurate methods of tramming is to ... 1. Center the spindle on your frame, workpiece or spoilboard 2 Obtain an aluminum rod or thick aluminum wire half the width of your machine bed 3. Bend the rod 90 degrees about an inch from one end so the tip can be chucked in the spindle. It will look like a huge fly cutter. 4. Lower the spindle until the rod almost touches the surface. 5. Rotate 360 degrees, noting the distance the rod is above the surface. 6. Adjust the spindle so the wire is the same distance above the surface in all positions of rotation. Using this method you can easily obtain accuracies way beyond anything you will ever need. For example, if you can dial in the rotational plane within 1/32" that equals less than 0.15 degree error if the radius of the rod is 24". Obviously you can dial it in even closer if you wish. PS: This is the method I use for dialing in the tram for cnc milling machines and am able to obtain less that 3 minutes of error consistantly. The error you receive will have more to do with your referance surface than the technique. Aluminum is used to minimize magnetic effects.
If you ever redo this video, it'd be nice to see some instructions for what to do if your switches are not aligned correctly. As it stands, it's kinda "Hey, this machine is square, if yours isn't, I dunno, fix it it I guess" ;)
Why is it necessary to level the unit to the floor? it seems to me the gantry moves along the metal frame , if the entire unit was set to a 20 deg angle the gantry is still level with the unit itself and it wouldn’t matter cause the gantry doesn’t ride along the floor
i dont mean to be offtopic but does anybody know a tool to get back into an Instagram account?? I was stupid lost my account password. I love any help you can give me.
@Kyson Jamal thanks for your reply. I got to the site through google and im in the hacking process now. Takes quite some time so I will get back to you later with my results.
Great instructional. I do think it would help to show what bad tramming looks like instead of just the already-perfect version, so we know what is good and what's bad. But a great video anyway :)
I'm curious why are you not levelling the basic table structure before adding on the extra heavy weight of the gantry + spindle + control boxes. Surely the use of a jack in jacking up at 1 end of a 600lb structure is just putting on all sorts of unnecessary flexing and strain on various parts of the structure / bolts/screws and joints. Just a thought.
Hi Adrian, I see where you are coming from. You can level the table before adding the gantry, though it would be a bit moot as it's better to level the machine after it is fully assembled, so you'd probably end up leveling it again. The machine table is quite rigid so jacking it up isn't putting significant stress on the extrusion or the anchor fasteners. That was actually part of our failure FEA (Finite Element Analysis). -Nathan
When you say "which side the ridges are formed will indicate if the spindle needs to be adjusted clockwise or counter-clockwise." can you clarify? If they were on one side, adjust which way?
Hi M W, At 7:26 there is an exaggerated animation that shows how the ridges look for different out-of-tram conditions. e.g. If you have ridges on the right side of the passes, then you should adjust the spindle counter-clockwise. -Nathan
cncrouterparts thanks! It may seem intuitive for others or basic enough to not have an explanation, but for beginners, detailed basic info really helps to get ahead. Other than that 1 question, the video is great and very helpful. You guys are great and i really appreciate how much you have already put out there for our understanding.
Thank you for the feedback! Yes, this basic workflow applies to smaller machines as well, though of course, the specific methods of adjusting & tramming the machine will vary. -Nathan
I agree, that was my first thought. This shows up on large milling machines as offset when changing between long and short tooling travel is so small compared to something like a bridgeport that it's not a problem in actual use.
Can I ask why you don't want to level the table to the floor? Why are we levelling to gravity? Surely if one foot is at a funny point, then the frame can twist slightly?
@@AvidCNC Thanks for the reply - just out of curiosity, do you ship your machines to the UK? Also, do these come with the legs? On your website I can't see them - I'm probably blind!
@@michaelkelly3158 Also, in regards to the leg kits those are sold separately because sometimes folks like to build their own table base. Check under "Pro CNC Accessories" tab below the "Pro CNC Machine Kits" link.

Hi. I just subscribed. I found your information very interesting, I planned to do a CNC. Regarding the calibration of the auto-square gantry, what do you think. Would it be better not to do the CNC with the two motors on the sides and instead, place a single motor in the middle, either with a spindle or band? I believe, that would avoid that movement. Thank you.
Yes, There is an option for 2 Z axes on our PRO Series machines. You can see an example of what that looks like on our Adam Savage / Tested.com video > ruclips.net/video/8OTwT0WFBmg/видео.html . Thanks! -Nathan

One of the simplest and most enlightening video about cnc router final calibration available in youtube. The best I've ever seen. Thank you!

Outstanding alignment video!! I picked up so much technique from your video. Thanks!
Thanks John! -Nathan
Why not use an "Indicol with an Indicator "attached to tram the spindle? Extremely accurate and fast.
Thank you for this video.

Is there a video that shows the logic on adjusting the stops when the machine isn't square?

@Pierce Nikolai No problem :)
Why not just jack it to level, then lower the feet so the jack it no longer supporting it?
Great instructional. I do think it would help to show what bad tramming looks like instead of just the already-perfect version, so we know what is good and what's bad. But a great video anyway :)
So is it possible to build a router this small for granite just to cut out sink holes ?
Can this be adapted to cut metal with an everlast plasma cutter?

Why not use a tramming gauge? Less messy and more accurate.

How does that sideways tramming nut work?? The one you tighten with the wrench
The eccentric nut rotates the spindle head, allowing you to pivot it left and right. Adjust it where it's square with the bed, then tighten.
Thanks Nathan. Just The cnc setup info I was looking for. I have a smaller machine but should use a similar process?
Thank you for the feedback! Yes, this basic workflow applies to smaller machines as well, though of course, the specific methods of adjusting & tramming the machine will vary. -Nathan
I might be overthinking this but wouldn’t having the adjustment plate on the portion that moves potentially lead to cuts being skewed to one side?
I agree, that was my first thought. This shows up on large milling machines as offset when changing between long and short tooling travel is so small compared to something like a bridgeport that it's not a problem in actual use.

yes it is.
Is there an option for 2 or 4 heads on your larger machines.

Hola lo pueden traducir en español y cuanto cuesta la cnc
Hello CV thank you for your work and thank you very much for your work. Is what you can do me a favor
OMG this seems like a lot just to get it aligned.
Hi, do you have the script home
Hello. May I ask you, what is it the machine. Company producer name and model name. Thank you in advance.
Great channel.
Who is thes cost
Very informative!
Pode fazer outro vídeo, alinhamento do esquadro. Mais detalhado.
Great tutorial. Thank you.
A tape measure for homing switches lol. Umm no. Dial caliper.
