I use a USB wifi device that links up to home network. My startup sequence for programs have a command in to disable the wifi, that way it cant' interfere with code running. Works well. Also have a...

Not a probe engineer either. But I do own a Tormach passive probe, and have opened it up. I am pretty sure there was no grease on the contacts.

Tormach sent me Service Bulletin 37 with the probe,...

Clean it off. That is where the contact is made and would explain the problems you are having.

Open it up and clean it. It is a simple device. Then re-calibrate.

Most of the guts was put in the M06 commands. I think it takes around 50 seconds to do a tool change (put away old and get new). You really notice how slow the rapids are when you do tool changes.

This is my interpretation of the wine rack solution. 5 tools. I used acrylic for the plastic parts, but have since changed over to nylon. I use ModIO board to actuate the standard Tormach PDB.

Awesome! Thanks for posting.

Geo

Would you mind posting a snippet of code to show how you do that?

Geo

I agree. The passive probe gives me 0.1 mil repeatability when I do edge finding two or three times in a row. Not sure it makes sense to spend more for the active if the passive is that good already....

Here is a link that shows Renishaw's method:

RENGAGE? technology

Active probes often times have strain gauges mounted on a beam. Electronic circuit excites the gauges and monitor threshold change to indicate touch. This method is used by Renishaw probes (not sure...

Even though I brought up concerns about balance, I suspect you are right. There seems to be plenty of evidence of people running at 10k without any issues.

The same goes for your question about...

I would not recommend reacting through the bearings. The contact stresses could be high enough to cause permanent damage to the race (my hand calcs show it is borderline). Each rolling element is...

I would be happy to give numbers if I thought you were genuinely interested.

I did run the numbers on the 1100 bearings, and they are not challenged at all at 5000 RPM. 10,000 RPM would be more...

Al,

You obviously know a lot more about electrical motors than I do.

I was thinking the 770 uses a 3450 RPM motor with approximately the same pulley ratio as the 1100, but maybe someone with a...

I have been looking at this for a while.

The spindles are not the same, and I am pretty sure neither are the bearings. My personal opinion is that the bearings in the 1100 are capable of 10,000...

A few thoughts:

1. I believe all outputs are already used on the Tormach (Coolant pump, spindle etc).

2. If you are willing to add external board (I use ModIO, which is serial interface), you...

Updated procedure I mentioned before:

Just some numbers to back up what I plotted. I had a spectrum analyzer and an accelerometer hooked up my Tormach to balance the rotor in place.

The FFT showed two distinct peaks when for S5140 :...

Let me know if I screwed this up.

The procedure in the manual is wrong, and will offset the probe by ~0.04". Set the probe in the spindle and rotate the spindle by hand - the runout of the tip will be obvious. There is a post here on...

Adam,

You can create your own set of screens and edit the button functionality to include a F10 into the macro. I use Mach3 Screen Designer for editing Mach3 screens:

Can you do a true milling operation on it - i.e. helical ramp so the bit is only in contact at one location? Or maybe open up the hole by doing circular profile milling?

Not sure if your geometry...

I never thought I would see the word "hater" in this forum.

Steve,

Perhaps a a short note to your customer to explain that it was medical problem would have gone a long ways towards avoiding...

I agree with everything you said.

Inner race fits change due to thermals (alpha mismatch between race and shaft, plus thermal gradient) and hoop stress. Outer race fit changes due to thermals...

Ray,

Three thou on this bearing is not crazy. The races won't distort.

Terry,

I created a special M-code, for example M1000. Inside I call G52 for the X-Y Offset from the regular spindle to the high speed spindle (HSS). So whenever I am doing HSS work I call M1000....

Thanks for sharing. Can you give us a little more info on how the data was acquired - specifically, how did you measure the spindle rpm?

Regards,
