Calibrate over the longest length (1000 mm if possible) you can using a very "pointy" endmill so you can more accurately see the distance or...
Do you have a short/loose wire in one of your Y axis motors? Shorts will cause the motor to not keep up and shorts it the wiring can also damage...
How did you find and set your XY zero point? Did you use a probe? Did you remember to put the right diameter of endmill in for your probing...
When you say "it cuts off an inch in the top and side and does not cut the way it should" which side is it cutting off? How are you setting your...
From the LEAD 1515 "Build" Page" OpenBuilds LEAD CNC Machine 1515 (60" x 60") : When using an OpenBuilds BlackBox all in one plug and play...
Are you using the OpenBuilds grbl postprocessor in Fusion360? docs:software:fusion360 [OpenBuilds Documentation]
But isn't that essentially re-probing the z height? I was going to add one to my machine, but realized it would take longer to have the machine...
Do you really need 4 axis? Or do you want a CNC router that has the 4th axis (rotary) capability. If you just need just rotary, I built this one...
If any one wants the .dxf or an svg let me know. I was going to add it, but there in no "files" section.
I had saved the top from a cheap old table from a big box store a few years ago because I figured I could do something with it. I finally came up...
Start with this and flash the Arduino, docs:blackbox-4x:connect-rc-servo [OpenBuilds Documentation]
A CO2 laser is not something you can mount on your next wave. CO2 lasers use large glass tubes filled with gas and excited by very high voltage....
Do you mean the soft limits let you hit the other switches? Not the ones used for homing. In other words, you are using limit switches at each...
There has actually been a couple of builds taken down by the submitters in the last year or two. As mentioned above, most likely for the...
Oh. I guess you would loose torque with the belts and pulleys. I do not know the max rpm and I expect it would depend on the voltage of the power...
I am curious what you are trying to move. I just rebuilt my old CNC Router and my Y gantry weighed 37 pounds before I added the router. It is...
You should read the grbl Wiki, or at least the "Configuration" part. It explains how it all works. You can set the max speed of your motors in...
DC ground is NOT the same as earth. Do not connect it to DC ground. You could damage the electronics. The ground on the limit switch goes to the...
I do not think you need to go 400mm. If your acceleration is too high, you will know it very quickly. If you have an e-stop, you could always use...
If your homing sequence is working properly you can enable "soft limits" in your grbl settings. It is very easy to do in Openbuilds Control. Grbl...
