Yes please, with video. Beautiful build!!

I worked in a glass factory for several years that made glass bottles. We had to cut the bottles periodically to gauge the wall thickness. I bought a diamond point glass cutter and used it for a...

Anyone knowing the manufacturer of this machine, please let me know. Sorry for the clutter.
Stepper driven, dual on the Y axis, belt driven X and Y, screw on the Z.

Another option for the machine controller is LinuxCNC which is open source (free) and works quite well. I have used it on 4 different machines over the years...

Yes that should allow you to tap off and isolate 2 pins for step and dir for the 4th axis, as well as tapping into an enable pin if used. Nice looking machine!

That is what I will be doing with some sbr20 rails on some 50x100mm extrusions. I have done a large machine with much larger rails on some 6 inch square aluminum tubing. The tubing was 1/4” wall and...

What motor drivers are you using? And what motors? Can you give us a picture of your machine?

Thanks

Catahola,
I hear you about having a little extra time with the current pandemic situation. Let’s hope we all make it through this safely.

Talking about couplings, motor to ball screw, rigid is...

Not sure if anyone here has seen this, but might be worth a look.

Hello Keith, although I do not have the plans you are looking for (did you locate them?), I did take a look at the men’s shed page. Wow, what a great idea! I live on a small Caribbean island just off...

I am not sure I understand the purpose of the additional assembly along side the spindle.

Where are you located?

Found a sketch.... similar, works for drafting horizontal bars...

Woodlover, one other note about using MDF or plywood or particleboard. If I were going to build a machine with those materials, I would construct long boxes to mount the rails to. Maybe about 6 or 8...

Hey there woodlover. Looked at the alibaba link, seems like a great price for what it is, especially the water cooled spindle.

The lengths of the rails in that kit will limit you to about 40” of...

Junior2016, WOW ! ?????? excellent build for the budget. Now ya just gotta make some stuff for the wife. ?? cutting board with a drippings catch trough, wood serving bowls...
Here are some I made...

Looking good! Drag chain support works great. I’ll probably do something similar with the drag chain, only needs periodic support. Access to heavy aluminum stock around here is pretty scarce. About...

If you want to do a little investigation and you have an iPhone, there is an app called “vibration”

Attach your phone to the lower end of your z axis, run the app, touch sample and then...

There are a lot of really intelligent innovative individuals who are members here and surely some of this group could help save some lives during this time of need.

1. There will be a major...

I had a bit of time so I searched back through my posts and found a pic of what I described.

Like my linear rails on that one? The tube and clamps on the back is what I was explaining.

Hey there machinedude, just reading through your build and love the pics. I am just beginning a build on my 4th machine. Your issue with flex in the bridge is something I ran into on my second...

Engraving is often done with a diamond drag bit. Spring loaded so that you adjust the depth of engraving by adjusting the z height. And spindle NOT running.

Hello, I noticed there have been no replies to your post, so here goes....

You mentioned that it “will not run through a dxf file”

This is understandable as a dxf file is a “drawing” file and...

Is it possible the focus lens in the cutting head is a Plano-Convex lens and it is upside down? IE flat side up. The only other possibility I can think of is that the laser is operating in TEM01 mode...

So I am finally getting around to the new build. I have the parts and hardware with exception of some screws.

Routalot,

Nice work on the Ferrari emblem. What was your total machine time? Some years back I made a small lithophane and showed it to my wife.... she asked “can you make some of those of the...

Try swapping the left and right connections to the y motors. If the problem of not moving on startup moves to the other side, the problem is in your drivers or wiring.

Just my 2 cents....
I worked doing vibration analysis and balancing for many years and found that often times noise came from quite unexpected sources in various machines. One unit I worked on was...

Looks great Eric, you may actually be a bit closer than you think. Acrylic changes dimension a good bit with temp. :cool:

That was meant in reply to your clear acrylic cuts that you measured....

I have one somewhere that I used when working on film developers years ago. It is specifically for controlling or stopping flow in vinyl tubing lines. Can’t easily find it right now so I will...

Great work! I wore a Vietnam era ribbon on my chest for some years. Now for your next challenge.... suppose you were able to 3d print the paint using the cnc. Perhaps with a small vinyl tube metering...
