Mine did get finished and has worked out well: https://www.cnczone.com/forums/diy-cnc-router-table-machines/258176-cnc.html
I have made a number of wood projects on it including crib for my grand...

The unit was replaced under warranty.
I have no had further failures after adding the capacitors and shunt reg/ clamp.
So far so good. I have not done a lot of routing yet. I am now in the middle...

Dave, this is great. Real analysis and moving beyond opinion. Your previous posts helped me greatly and surprised me in the gantry beam analysis , which was borne out in my machinig. Now I really...

also checkout the 8020 close outs on ebay. Some real deals there if you are flexible with your dimensions or willing to take some slightly used pieces .
The very long gantry will be an issue however...

Interesting. This past weekend I was making some parts and went to move the gantry out of the way. I ran it to the far end (fast) and stopped. Cleared the parts, installed the new blank and returned...

Revised machine.ini file attached. Now I have the probing working for tool xeroing. Running Mach 4 build 2803 and ESS build 130. ESS plug in wont let you select/ create a rpbing input or claim some...

The router is now in productive use. My primary area of interest is woodworking with the router intended to be used largely for joinery. The top is built of 3 layers. 1/2" MDF bolted to the frame, a...

Here are the photos of my dust shoe. It is a 2 piece design with the fixed portion screwed to the bottom of the z axis slide and the lower section held with rare earth magnets and 2 brass locating...

The 2 wire method can get the unit so that the side parallel to the side you leveled is also level but no necessarily in the other axis. If you leveled one side of the Y axis , after the wires just...

Yes you hit on one of the key points I left out. The "back rail" held the high point among the legs. The high point leg really became the reference for the overall leveling process. Everything else...

mine was a bit smaller. 4x5 foot. First I leveled one rail that ran along the Y axis -my "back rail" with a precision machinists level. . This became the reference for the other pieces. , Then I...

running 50 in /s/s for acceleration on x and y, 30 for the z. I am just starting to use this and i don't think it iis fully tuned yet. there are times when there seems to be an extra "shudder" in the...

Hi Daniel and others,
How are you using the laser edge finder?. Is it in the spindle collet or permanently mounted with known offsets?
I am debating whether to use a laser or endoscope camera...

Low end is not for cutting but using an edge finder.
Certainly don't want to cut super slow and at the bottom end you can stall the spindle by pinching the collet in your fingers
I hate running...

Progress has been slow due to interruptions and other projects that had to get done. However today was a rainy day and my wife was busy hosting a baby shower. So I had some free time to fix up some...

Update:
Homing of the axes. I had tried adjusting the home speed in mach4. I it is however ignored by ESS. So you have to go to the ESS plugin to set the home speed. I am currently running 10 units...

When looking for structural tube, don't ignore salvage. My local steel supplier ( Pal Steel , Palmyra WI) has both "new" and "salvage" and will torch cut to length . Salvage is 1/2-2/3 the price of...

I doubt it is the power supply. That would ave most likely hung the computer if it was bad. Rather I would look at the machine components themselves. Particularly spindle control / super PID. It...

In response to some other questions, the drive system is based on linear rails and ball screws.
15mm linear rails (NSK LH15BN) 1680mm each for X and Y
20mm diameter 10 mm pitch rolled ball screws...

Lets back up a step.
The forces being applied are too much for 15 series extrusions. See: http://www.cnczone.com/forums/diy-cnc-router-table-machines/205766-cnc-cad-posts.html thread for Dave...

I had to change my orientation. When initially building I looked down the basement shop at the machine. From this vantage point I envisioned the X asis as the base rails and the gantry motion as Y....

In naming the axis directions my first thought was start at the bottom. However, in some of the replies and other posts that more folks think that the gantry travel is X, the base double axis is Y...

Yesterday I made the first test cuts.
Y axis diagonal leg braces were added. It shook a lot when moving the gantry. Rapids are comfortably 250 IPM, i could probably push higher,
Getting Mach 4...

I just bought one of the water cooled 2.2KW units from automation technologies. I am running it with Teco 7300CV 3KW drive from factorymation. I have Teco units on my mill and lathe and they work...

Interesting thought.
Up until I started the testing, I had always been looking at the machine from the side - facing the white wall which is on my right in the video. Based on that I have thought of...

First motion.

I purchased the motors and controller hardware form Automation Technology. John was helpful and even did a free saturday...

Yaxis / gantry rails mounted on. One high spot on the lower rail (z direction by about a few thousandths). A few more passes, check with straightedge and a little pressure while screwing down and it...

Thanks. I have been toying with doing that, adding diagonals form the legs towards the center under the side rails. I can easily weld up the pieces but now my outside work area is buried in a foot...

I am building a router with a mix of aluminum extrusions and steel. Structure:
x beams, legs and risers for the Y carriage are Bosch-Rexroth 9090H. Legs are bolted on with Bosch 90 mm corner...

You might consider thinning the epoxy ~2% with acetone. This dramatically reduces the viscosity with modest decrease in strength. WEST SYSTEM - Projects - Thinning WEST SYSTEM epoxy
