I'm new to CNC. Wondering if anyone has problems with the touch off puck damaging bits? I'm especially wondering about the engraving bits & 1/32 ad 1/16 tapered ball nose bits. I'm hesitant to attempt a touch off on those bits. What have others experienced with this?
Thank you.

I have had my AR 8 for a few years now with no issues. However, I was concerned about something similar, so I lowered the speed of the touch-off in the settings. Now it touches off VERY slowly. So, in order to not have it take 20 minutes to zero the tool, I manually lower the endmill toward the stock (with the puck out of the way so I don't accidentally overshoot and drive the tool into the puck), then move it back under the puck and run the zero operation.
It works quite well and I'm no longer seeing small divots in the surface of the touch-off puck from the automated routine driving it too quickly downward.
If you check your manual, you should be able to find the settings in question and lower the values to something you're more comfortable with. Or, you can check with Axiom on how to do it and I'm sure they can provide directions.

I have a B18+ controller for a Axiom Pro V5. I have my TOOLSET SPEED set to 150. This slows the descent of the bit onto the puck greatly. Lower the Z at full speed NEXT TO THE PUCK, then move the puck under bit and hit TOOLSET. Measure your puck height with accurate calipers and set CAD THICKNESS appropriately.

I use the bits you mention on several different machines and have never had a problem with damage to the bits.

I use 1/8 shank engraving bits from Precise Bits and if the puck is used it almost always damages the tip even on a slow speed. For those applications i like to use a thin sheet of paper to set Z. I bring it down manually until it just barely touches the paper. you can feel the point snag the paper when you slide it so it gives you a pretty accurate "0". |

As stated..... slow your TOOLSET speed |

Or use a piece of paper....for bits the size of a needle

It is a bit overwhelming to me right now. I am the kind of person that want to run before I can walk. So I want to know all the functions of the controller and how to program it properly. I will look in setting to see if I can figure out how to slow the speed of the touch off Thank you all for the information |

The puck is soft, much softer than the carbide bits I use. I haven't noticed any issues with bit damage, but I have had to resurface the puck.
I don't use a lot of tiny fragile bits in my work, but if I did I might be inclined to try adding a thin neoprene wafer to the bottom of the puck. As Gerry wrote, anytime you do anything with the puck measure it and set an accurate thickness.

If you slow your toolset speed down you will have zero issues. Also one good piece of advise, zero off the bed of your machine whether its your waste spoilboard or the machine MDF spoilboards. It will be the constant, whereas if you use the material to zero off it can and will have variations in thickness.

I tried to go to the auto pro setup and the toolset speed and toolset fall are not on the Menu, Any ideas that I can look at? I am going to email Chad but just wondered if anyone else has this issue? |

Start at Machine setup. Then go to Toolset Setup, then toolset speed. I have mine also set to 150. Once you do the toolset you'll get used to the slow speed. Just bring down the Z close and then do the toolset itself.

First hit menu then the above procedures.
