It might be that the X and Y axis are not perpendicular to each other. Circles (or gears) would become ovals.
Other possibilities include loose belts or pulleys creating backlash. One common...

Involute gear cutters need slightly different cutters as the number of teeth changes. The tooth profile might be similar, but you are cutting the space between the teeth, instead of actually cutting...
I see what you mean about limited options. I looked further and see mostly 800W 120V ER11 spindles or 1500W 240V ER16 spindles. Maybe you have to decide if ER16 is that important to you, then you...
So if all you need is 750W at 120V with ER16 collets, then why not just buy an 800W 120V ER16 spindle. Do a search and several choices should be available. Most inverters appear to be 240V, but a...
The importance of being square is dependent on what you are making. Signs and cutting boards can be a long way out of square before it matters. Clock gears are a lot more important to be square,...
There should be minimal risk as long as you are cutting chips and not burning it with a laser.

I was at 60ipm rapids and 40ipm cutting with my original 10tpi acme machine and HobbyCNC controller. It would sometimes stall cutting and I would back off to 30ipm.
I switched to 5mm ballscrews...
I don't see any problems. What are you trying to do exactly? Cut your name into them so you can identify yours? They are cheap enough to just try it and see how it goes. The worst case is that...
Maybe a 500W spindle would be closer in weight to the 5A 600W Ridgid router. They appear to typically be 52mm diameter, compared to 65mm or 80mm for the 800W spindles.

One other option for a sheet like you are cutting is to treat it like a piece of plywood and add tabs to each shape. Secure the perimeter with screws. It might also help to add 1 or 2 screws in the...
TurboCAD
I started with it about 10-15 years ago and it seems fairly easy to learn for a low cost program.
Hi OmriBig,
I know this post is old, but I just stumbled on it and hope you can answer a few questions. The drawings are extremely cool.
What software did you use?
Did you have any feedback...
Or if you really feel like trying different materials, how about using a hot glue gun. It hardens much quicker than silicone. There are many types of hot glue. Some are more flexible than the...
There are many websites that sell plans for wooden gear clocks. Most recommend Baltic birch plywood, although some people use solid or segmented wood. Here is a closeup of some segmented gears cut...
As Al mentions, the primary concern is the quality of the output signal.
This is a somewhat standard AC to DC power supply, although the currents are quite large. The bridge rectifier converts AC...
I like this idea the best. The fan is needed when temperatures rise, not simply because of RPM. I haven't looked for a solution, but it seems like it might be simpler. There might be a ready made...
Looks good. The Makita router seems to get good reviews. And it should be easy to replace if you wear it out. It might be a good idea to keep a spare set of brushes if you use it a lot.

Searching for a loose component would also be my first plan of attack.
If it turns out that the ballnut is actually worn, then it may be possible to re-pack the ballnut with slightly larger...
We need a lot more information about your machine to debug a problem. All we know is that you have a Gecko controller, Mach3, and ball screw on the Z axis. All these are expected to operate quite...
As mentioned previously, TurboCAD (and possibly many other CAD programs) can import STL files. The scale may be off it it was drawn in mm and loaded in with inches. That is easy to fix. If the...
Can you use air cooling?

Interesting idea. What is the cure time of silicone caulk with a water mist? A typical 3D printer can print another layer after a very short cure time, something like 1 second. It would take...
Welcome to the forum.
You may already know this, but mechanical clocks are conceptually very simple. They have a power source that turns a gear train, and an escapement that slows the gear train...
The video looks like normal operation of Photo Vcarve. It carves deeper in the dark spots of the image.
Maybe try adjusting the start and stop depth so the lightest portion is just below the...
If the Z axis is not losing steps, it could be a bed leveling issue. Try clamping down a sheet of MDF or cheap plywood and run a flat router bit across the entire surface. Then see if an object...
That is very nice looking.
Did you drill the holes with a router bit? Or would it be better to use a brad point drill bit with lower RPMs? Your holes appear very clean straight off the machine. ...
Do a search for "auto leveling" and see if the same tricks used for cutting PCB boards would help in your case. It starts with a surface map generated by a touch probe.
Here is an example...
If there is a Rockler woodworking store in your area, they may have several models for you to look at. The store near me always has 3-4 models in stock.
They may even have live demos. Some of...
I usually do a multi-pass rough cut at high speed that is offset about 0.005" outside the line. Follow this with a full depth final pass on the line at a slightly lower speed. This seems to reduce...
I agree. The OP mentions a desire for super straight rails. I doubt that this would have much impact, especially for a wood product that will be subject to expansion due to humidity.
Low...
