If you’re just interested in cutting the concave slot in the bottom, why not just put it in a vise and run the length with a 1 1/4" ball nose EM 7mm deep?

Make sure you set compensation to "Wear", for contour and that same for the final pass in pockets. That is for MC. This will put in a G41/G42 and corresponding D value for the tool.

Just read this on the Xylotex Yahoo group

The tall vertical button next to the Zero X, Zero Y, Zero Z, and Zero A buttons, on the "Program Run Alt-1" screen will move the Z axis up till it triggers the switch, then the Y will do the same,...

Active low means when there is a logical false, or 0, or an electrical GND, and triggers if this is true. Active high is the opposite, logical true, or 1, or 5+ on the line, and trigger when this is...

Yes, that way if a wire breaks it will trip Mach3 and you'll know before the machine crashes into the end of the axis.



The terminal block with VCC and GND, not the one with VBB and GND.

I've looked at the web site, and haven't seen any prices at all, base or otherwise. Do you have a link that goes directly to this page?

Thanks,

No limit switch for the Z, your tool will be cutting the table long before you've hit the end of the Z travel going down.

Home switches are very useful if your going to be using offsets like G54,...

Yes, here's the diagram from Xylotex on hooking homing switches up in series. You'd hook them up the same way, just use them as limit switches instead.

Mach3 can share switches. So the Home switches can also be the limit switches, if they are positioned at the end of the travel.

The other 3 limit switches are usually hooked in series and closed...

Home switches tell the CNC controller where machine Zero is for the X, Y, and Z. I got the ones from Hightech, and they mount pretty easy. I used this diagram from Xylotex to hook them up. The one...

Need to add "Mid-band resonance damping" to the chart.

Second paragraph in the manual

"The current set resistor may be a 1/4 Watt, 5% part", standard Radio Shack stuff.

Might want to look at this site, it has some good info on Taig motor
upgrades.

True, but the poster said "I want the tool to cut 1/8 inch outward", so .125 would move the tool .125 outward or away from the contour.

That's correct. For instance, if you choose Contour Method "Outside Offset", then a Finish Allowance of .125, Sheetcam will use the tool diameter to offset the toolpath so there will be .125 material...

Yes, using .125 as the finish allowance will leave .125 all the way around the
circle. This is the correct way to do it.

The instructions that come with new Taig pulleys, say not to use any kind of hammer to put them on. You can just put the pulley in a bowl full of boiling water for about 5-10 minutes. It should just...

Nick Carter has a Magnetic Spindle Depth Stop description on his pages. I switched from the High Tech to and ER spindle and the depth stop mod, and love it along with the extra Z clearance.

The...

Using Modify->2D Boolean Operations->2D Subtract, subtract the circles from the object and they will become holes.

Try selecting all the lines in the object and then the Menu item Modify->Join Polyline, click Finish, which can be seen as a checkered flag on the menu bar at the bottom, or by right clicking. Then...

Don't know what kind of edge these would leave, but they cost way less than $15 a pop.

If your not in a huge hurry, and you think you can add steppers onto a CNC ready Taig, you can save a lot by doing it yourself. You can get a CNC ready mill with stepper motor mounts and...
