If your machine is complete with a pc running Mach3, and is currently working, you may be best off staying with Mach3. Mach3 is very well supported on the internet and from the author, and should be supported by NWA as they once sold it. Mach3 has more features and a more complete (and complex) inte...

If you have machines that have the 1/4 " dia stepper motor shaft extending out of the back of the motor, you can mount lightweight knobs on the shaft ends to allow you to easily turn the steppers by hand when the power is off. This lets you fine position the axis, and also check to see how difficult...

You may want to repeat the cutting of the circle using a flat sided bit if you are have any trouble measuring to the bottom of the V cut for the circles dimension. You can't go off of the top surface measurement as that will change if you have any Z fluctuation over the surface of the table, and you...

These enclosures just keep getting better. New ideas in almost every one. Great work.

If you cut a plain circle, as you have, it should not be out of round. It may be a backlash issue, so double check that your lead screws on x and Y are tight and gripping the shafts tightly. also, check your router mount again to be sure it is holding the router body very tightly. Then cut a test pr...

Hi Bob I downloaded the new circle 2 file, opened it in Vcarve 6.5, generated the tool path for the main carving, ran it on my pro generation machine (in air) with Mach3, and there was no shaking or pounding at all. However, though the cut speed is set at 100 ipm, in the short sections, my typical s...

Just wondering out loud if it might be an issue with acceleration rates being set too high. I don't use the NCpod , so I do not know if that is user adjustable or factory set. In Mach3 it is user adjustable. Basically, if the ramp up time is too short, at high speeds the changes in speed become too ...

I have see that video and I think he is addressing the bow in the table, which is an issue in itself. Johnnypingpong has most likely overcome that with a slab of 2" material which he milled down. It should be stiff, but ends up not "flat" after milling.. The second problem is flex, which the video d...

You are probably seeing the sag that is in the machine due to weight of the components acting on the unsupported bearings. I can't recall if my results were exactly the same as yours, but they were quite similar. That piece of 2" material was not cheap, and I think what has happened is that you have...

I ran the cut files individually, in order. Did not have any issues with the ones that start below zero in the z axis. all ran as I imagine you intended them to. I did slow the cuts down to 30 ipm in the tool profile in Vectric, and ran them up to 60 ipm in Mach 3 as the first one was cutting. I had...
