I have a 10/2018 built DT-2 with a 10K spindle. So far I have not seen any problems like you are having. I did have a TSC union that was squealing so bad my wife (in the house) asked me to shut it...
In case someone is interested this mill is now up for sale. Currently listed on Craigslist in the Minneapolis area. I have upgraded to a Haas to get simultaneous 4th axis without having to build it,...
The project has been side lined, its available for purchase if anyone is interested. A paying job expedited the need for a 4th axis, so I bought a used one this last spring and have not looked back. ...
Have you considered the MASSO controller? Eliminate the computer cost, the Mach3 license fee.

Tom,
I have a Kanalog and I am running 3 AC servo drives and a VFD off the standard -10 to 10 vdc output. But I am now looking to add a 4th axis that already has a brushed DC motor with encoder on...
Mike,
When I mentioned closing the loop in my motion controller it was not for solving the instability issue, it was just to keep stable RPM's at all other times.
I will have to come back to...
Mike I was stepping though the RPM range of my motor and hit a spot at 800 RPM (700-900) that acts really weird. The RPM jumps around, it sounds terrible (much like a helicopter coming in to land)...
Well I got the operator panel put together and operational at the end of last week during the Thanksgiving holiday weekend and just in time for a few runs of parts I needed to make. So here are the...
Look for an end mill with a corner radius, they will hold an edge much longer. If you need to end the cut with a square corner then switch to a square corner end mill to finish the cut. I didn't see...
You are right that Tom wanted me to test the code out using an M code and passing some variables like a sub-routine. Part of the problem is laziness on my part and part is I don't wish to hand write...
Mike,
I will be tapping and possibly drilling with 1/2" and larger drills in steel or other hard materials. But all of those operations should be done in excess of 50 RPM, so maybe 50 RPM is a...
The honest true about the rigid tapping is I have too many irons in the fire to really have time to work on it and when Tom suggested running it as a G-Code sub-routine type program I became...
Yeah I have a KFLOP and KANALOG boards running my mill. I have also added a Automation Direct PLC for added IO and some basic functions that the KFLOP does not do, like ethernet and Modbus 485. I am...
Mike,
What do you think it is a big disadvantage to use the free voltage/frequency setting instead of the Sensorless vector? My biggest concern is establishing the voltage for low speed, too low and...
Progress is slow but steady.
I got everything mounted to the front panel and the initial wiring done so I could test it all out this last weekend.

Then I got the bug and dove into...
I just looked in the Hitachi manual over my lunch break (didn't have time before).
The A045 setting will not help, I was thinking it would go from the A045 setting*the AVR voltage at the base...
Mike,
I hope you got your internet connection fixed.
I may have muddled something up in posting the info I did. Here is a better breakdown of how I have configured things. I ended up pulling the...
Mike,
I am quite intrigued, and look forward to the information you have. I spent a fair deal of time trying to find engineering level information on these high speed motors and always came up empty...
mactec54, Did you even bother to read my full post before hitting reply? I appreciate helpful feedback, and even constructive criticism. But I am beginning to feel like your goal is to refute...
I have had many inquires about how to do this, and a few people telling me it can't be done. In the past I promised to do a full write up on how to run a high speed induction motor like a Fanuc on a...
I made a little more progress at the end of last week. I got the monitor mounting bars machined. But when I went to mount the monitor I got a surprise, it did not fit. The factory spec for the...
No major updates on this project right now. Right now I am focused on finishing the operator control panel on CNC mill, until that is finished I can't use my mill.
These pictures are basically...
A little more forward progress.
When I machined the front panel I was not able to get to the very edges of the panel due to the enclosure on the mill. So the additional screws I wanted to add...
Getting even closer.

A little more progress, the 24" X 24" steel panel has proven to be the most difficult part to machine so far. The problem being its size and the enclosures on the my mill and the mill at work....
I made a big step forward this weekend. I finished out the mounting bracket, short of painting it, and got the enclosure hung on the mill for the first time.

Next up is...
As of right now the only switches I know I am going to have are
Cycle Start
Feed Hold
E-Stop
CPU Power
CNC Power
Program Stop
Program Rewind (go to the beginning).
Switches I would like
Whoa simmer down fella, crazy thoughts of new fangled backlash free 4th axis setups imported from overseas, could get you thrown in the loony bin.
From what I have read the name "Super Spacer"...
Another step closer, both of the pivots/hinges are done.

Now I just need to get the "spine" that holds both pivots to the machine made and I can hang the enclosure.

The motor does clear. Below is a picture from the back. The motor is hanging just a hair over the edge of the hole but the motor mount is at 90* to the back in this configuration. It will actually be...
