You will not be able to build one with that kind of accuracy. Commercial routers in the 6 figure range do not achieve that accuracy. May get repeatability in the .005 range if you know what you are...

For free or cheap CAD and CAM check out Fusion 360.
USB-> parallel adapters do not work for CNC. There are USB -> Parallel Motion Controllers like the UC100 that do work. Are you using a Genuine UC100?
A 65 foot by 32 foot machine may be a bit too ambitious for a first timer...
Assuming you mean millimeters, you probably will need much bigger than 8mm acme screws. You may want to spend a little...
Both er11 and er16 are families of collet sizes. Er11 it’s 1mm - 7mm shanked bit, ER16 is 1-10mm, and er20 handles 1-13mm.
Approximately the same range available in SAE sizes (1/16 - 1/4, 3/8, or...
Gary Campbell has built a very nice example of what you are thinking of

That will represent the no load best case, but not the loads due to cutting, bit deflection, etc. If the structure is not stiff enough may even get gyroscopic loads fron spindle running.
If you calculated mechanically it should take 2000 steps/inch then changed it to 2022/2030, parts should have come oversized. (Would have commanded more steps than necessary to move any set distance)...
You probably should have different steps/inch on Z than for X and Y. This is a number that is calculated based on the hardware, not something you “adjust”. If you need to adjust this, you have...
I have not bought from them, will be interested in what quotes are provided. On my own machine I decided to embed a grid of t-track and have been happy with how it’s working out.
I would think the...
Here is one source.
Super Wide and Flat Extrusions
On my machine I designed the gantry to be adjustable in height. The Z travel remains the same, but the entire gantry can move. The gantry attaches via a piece of angle to an 8020 extrusion vertical...
The control computer does not need to be very powerful. Use the i7 for your CAD/CAM computer, the control computer should be dedicated to only running your control software, and does not need i7...
Since Fusion 360 is capable of doing the CAM (creating the g-code), why are you exporting to DXF and importing into Aspire? The g-code you posted does not have any g2 (arc) commands - the code is...
On my machine the touch probe input pin is normally high, pulled low by the bit grounding the plate attached to the input pin. Is that how yours operates?
My touch probe is a piece of brass...
Another few months of reading will help, 2 hours means you haven’t read enough to find the advice to build your frame first and determine what your requirements are before buying drive parts. The...
Certainly not the “fastest diy cnc” I’ve seen by a long shot. A regular router bolted to a sheet metal support does not inspire confidence in the sufficiency of the rest of your design. Unless...
In that second photo is there another bearing outboard of the large belt sprocket? The one bearing visible is certainly not sufficient. The belt should also be the full width, as large as possible....
There are lots of interrelated aspects that can affect accuracy and precision of cuts. Please do not take these questions as criticisms, I am providing them as a checklist of things for everyone to...
Since I never got any feedback to my original post, I did end up tying -V on the 48V supply to ny star ground point. Works great. Note that all of my electronics are gantry mounted. See my build...
You are correct, I never realized the G540 "output" pins are simply a switched connection to ground. Could of saved the $5.99 the relay board cost me!
You WILL need a relay, or could wire a simple switch. Continuity between the VFD FWD and GND acts as an enable signal to enable operation of the spindle. No power or current flows (only logic level...
Are you moving gantry or table? How much will it weigh? What kinds of speed do you need to machine the materials you want to cut? Rotating shaft or rotating nut for the ballscrew? Direct drive or...
I bought similarly sized CNC router parts version, 420 oz-in, they have a little lower inductance (3.0 vs. 3.8mH), came already prewired with the same DB9 connector that the Gecko 540 uses (you will...
I'm pretty budget constrained- I caught the $99 special. I belong to a group of cnc users here in Colorado and almost all of them use Aspire or Vcarve Pro. So far I have been able to replicate...
Since Autodesk purchased the ArtCAM titles from Delcam last summer, the offerings have changed somewhat ArtCAM Standard 2017 is the current offering that would do what you want, and it is $360 per...
Sizing steppers is something you will need to do. We don't know anything about your machine, how big, how heavy, what kind of drive you have planned, what linear motion components, etc. The best...
You might want to look at Cenon. They have a vision system integrated with CNC. Cenon CAM - Manufacturing with Style
The Gecko G540 is only rated for 50v, and a max of 3.5A per axis. Do you have the current limiting resistors in your stepper cabling per the Gecko documentation? Exceeding its ratings is what would...
I am coming into this discussion late, but I want to ask a question. Is your goal to build a CNC robotic arm router, or is it to carve designs that cannot be made with a conventional 3 or 4 axis...
