Note that Taig laps the screws and nuts together so you might be better off to replace the two at the same time:

I thought I read they were using an ethernet Mesa card with the breakout board in the computer control cabinet. I could be mistaken though.

Did you verify the probe setup after you switched to 2.0? Effective diameter, calibration etc... Depending on how you did the upgrade, those values could have been lost.

Ken,
Check out this thread: https://www.cnczone.com/forums/open-source-controller-boards/176725-arduino-controlled-coolant-nozzles.html

Your wiring does not match the diagram... Black and blue are transposed.

Look for parabolic flute drill bits. They do a better job of clearing chips.

I like the vacuum former in the video. It is a nice simple design.

Are you chamfering the hole before tapping?

Vise keys.

Maybe an enclosure like the ine in this video would do the job.

I suggest browsing through the forum threads and see what people have build that matches up with what you want. Pay close attention to whether or not the build was ever completed...
While it is a...
I was curious and I checked the documentation. (7.4.6 Tapping Cycle – G84 in the Series 3 manual). It says the same thing as Mactec. The Mach canned cycle probably had a shortcut for it..

Your test is too vague to isolate the issue. All your test proves is that there is a problem between the spinny bits of the spindle and the housing. If there is a locking key for the toolholder,...
Peatol Machine Tools - Home of the Peatol Micro Lathe should have the parts you need.

If you want a project, this looks like the motor he is using:

To me there is way too much distance between your X and Y rails. They should be as close together as possible for maximum rigidity.
bob
The slow speed performance is not unexpected. AC motors are essentially constant torque devices up to the rated speed and constant power devices beyond. This means as you slow down, you have less...
As an alternative approach, have you looked into the Pierson pallet systems? https://piersonworkholding.com/ The initial outlay is higher than the vises for sure but it is basically plug and play.

I don't see how you are going to do rigid tapping with a router spindle. Once you get down to rigid tapping speeds, you won't have a whole lot of power left. You might be able to rigid tap small...
It would be nice if the controller kept track of how many times each tool holder position was involved in a tool change. Then when the screws break or you replace a fork you could record the count...
You are neglecting that the whole system contributes to damping, not only the load bearing members. Taking your assertion to an absurd conclusion, an EG filled metal wind chime would make the same...

I am sure you can get a similar removal rate from the Tormach but you aren't going to be able to hog it at 300 rpm with a 1/2" end mill. At that speed in low range, the Tormach is only putting out...
25.4/5 * 45 = 228.6 rpm
The chip trays will be a pretty tight fit in there. If the walls are chip and coolant proof you are about half way to a nice enclosure.

Is the backlash the same across the travel? If not perhaps you re-fixture the parts so that the critical feature is on a good part of the screw.

Get an auto-reversing tapping head for the small taps. Don Clements has been using a Procunier for years with great success.

Read up a bit about Abbe errors...The subject usually comes up in discussions about measuring but they are entirely relevant here. In a nutshell, the further from the tool the nut is, the more...
