I designed, and built a 4 axis Router table. Unfortunately, it (along with EVERYTHING else I owned) was lost in a fire. I have since rebuilt my shop, and replaced a few tools. Still need to replace a...
I know that we are in the middle of a pandemic, and things have definitely changed. However, it seems that with all of the "shelter in place" mandates and such, if anything, folks should be spending...
I realize that this post is a couple of years old, however, I worked extensively with MeshCAM Art to create the Rattler in these photos. I also worked with Corel DRAW to create the artwork used. I...
I have been a member of CNCZone for years. I designed, and built a 4 axis cnc router table. I used it to carve many thousands of wood carvings for friends and family over the years. However, in 2019...
Yes, the driver does work. And the round rails are fully supported in an aluminum base which has been machined to cradle them.
I bought this CNC router table from a man named Kwang Kim, who had owned it for several years. The only info he had from the previous owner, was "they used it to cut aluminum". There are no labels,...
If you are talking engravings into WOOD, I can tell you from experience, that this will be the ultimate "test" of the acuracy (and consistency) of your machine.
IF it is acurate, and consistent...
Gravity is a powerful force to be reckoned with. When you start mounting things like the linear rails, and the trucks for your gantry, it's best to have things oriented as near to perfectly level as...
Judging from your picture, it looks like a pretty good design. One suggestion: Begin NOW writing your "Owner's Manual", include as much information as possible for your own future reference. Things...
I originally wired limit switches at each end of travel for each axis on my machine. But after some use, realized that the only switches which were really needed were the home switches. (Which I had...
It depends on your design. If you have designed your machine for adjustability, it is a fairly straightforward process. If I am correctly comprehending the ads for the Edge Technology dial...
I suppose to answer the question of "Why shorter?" Because the taller it is, the more reinforcements you will need to stabilize the machine from rocking during use. However, it all depends on what...
What I did on my table is to construct a frame out of 1/4" thick 2"x2" angle steel, with 1" square tube steel cross supports with 1/4" thick flat stock shims/support under the 1" square tubes. For...
As the old saying goes: "There's more than one way to skin a cat" Like you, I started out building my own machine not really knowing what I was doing yet. That was in October, 2008. A LOT has changed...
This can be done, by editing the Post Processor you are using in whatever software you are using to generate your tool paths. Or it could also be done manually, by editing the g code to move to your...
I don't use ArtCAM, but the picture you posted looks like it could be easily handled by CNCWrapper. While the CNCWrapper software is great for converting 3D gcode into 4th axis gcode, it also has...
Whether it is a belt drive, screw drive, rack and pinion drive, etc. there will always be issues with wear. I have never built a system using a belt drive before, but have experience with other...
I frequently use the following method:
Cut the profile to within maybe 0.010" of the bottom of the stock. Unclamp the stock from the table, flip it over, and for added support (to prevent splitting...
Looking at your photos, it looks very similar to the earliest iteration I tried on mine for a dust shoe. The final version ended up just having a plexiglass top, mounted to a plywood frame, which was...
I too, experienced this problem when I first started trying to set things up. I ended up going into Motor Tuning, and reducing the Velocity for each axis slightly. This seems to have eliminated the...
Thanks, Gerry! Solved the Z Zero problems.
Gerry,
I've been working with the 2010 screen set, the last couple of days. Finally got things wired up and working correctly. There is one item, that would be a very nice improvement: an audible...
I was not sure how to wire things up on my G540, and read thru the manual several times. The 4 inputs available are listed as "general purpose" inputs. I was already using all 4 on mine (since...
Thanks, Gerry. I am aware of the need to re-zero the new tool during a tool change, and have been doing that for years. I really want to try out the 2010 screen set (and autozero macros) but quite...
Ger, I too am trying to set up Mach3 to go to a fixed location (Machine Coordinates) for tool changes. Is it necessary to add the DoStopSpin() after the tool=GetSelectedTool() SetCurrentTool(tool)?...
My first test was a hand written G code file. But the same "Test Pattern" used for testing a computer printer for aspect ratio accuracy, would be a good test for your machine as well: Draw a perfect...
I don't think he was referring to engraving, but carving in 3D (RAISED lettering). There is a BIG difference between to two operations.
I think this is the actual video which served as my inspiration for my cyclone design.... I basically built the same thing, with the only difference being, that I mounted the blower & motor (of my...
With MDF, it's already saw dust before you even begin cutting. (cause that's what it's MADE of). For any sort of precision carvings, I have learned that hardwoods are the ONLY way to go. You might...
