That is good news. Which Drewtronic's probe do you have, the TTS shank or the 3/8" shank?

I bought the one with the 3/8" shank. I then put it into an TTS holder that I had here. I don't see the benefit in getting one already in a TTS holder its cheaper to go the route I did. Possibly the known gauge length you get when you buy the one already in the tts holder is an advantage? The repeatability is great but the final numbers it gave me for bore size was way off. I have to calibrate the Y axis. I though I had done it a while back but the probe pointed out the error and it was correct. Verified by measurements. I should be able to get that done tomorrow and then I will give another report.
That's good news! We use similar power supplies at work. When they get over taxed, they "crowbar". Removing power for a minute will reset them. It's pretty rare that we actually kill one of them, but it does happen.
I like the spec on the drewtronics probe. Just might have to consider one of those too. :)
I'd like to have the same controller on my little lathe and my mill.....so the Siemens doesn't really appeal to me too much......but the price would be the real reason. lol
I think John is aiming his new mill at the Tormach MX market with the Siemens control, all servo motors, rigid tapping and a 6,000 to 9,000 RPM Spindle. I am sure the price will be higher as well. He will need a PDB and maybe an ATC for it as well. I don't see guys investing in a more expensive mill which does not have a PDB included or at the very least as an option. I bet this new mill is many months away from actual shipping.

I got the Y axis calibrated and also the probe tip. Numbers are better but not perfect. I think its a problem with my measuring system I need to set up something better for testing. Worst case was out by .010" I'm sure this was because of my setup for measuring I need to find something with a good calibrated bore for final measurements. On some of my randomly chosen bores from the shop it was within .001". If that is the case its good enough for anything I have planned.
Like you mklotz70 I also want to stick with the same control for my machines. I have a second cnc mill and a small cnc lathe as well. I would like to have them all on the same system. If the new control from Novakon comes out soon I will have a look at it and then decide.
I'm interested in seeing the new mill from Novakon. To be honest though Steve I don't see another Novakon in my future. The one I have now was bought new but since then the company has moved to the USA. Bringing the machines across the border is expensive. From time to time older little used machines pop up and are good candidates for a new control install.
Did you get your PDB setup yet? I just did this a few weeks ago while installing UCCNC / uc300eth-ub1 in my new Torus build.
*Take note* There are 2 white wires, one is spindle direction (pin6) and one is ground (pin3)
6pin---Novacon BOB
W --> Direction Fwd/Rev from Acorn
R --> Vc Spindle speed control from Acorn
Blk -->Ground/Common for I/O from Acorn
W --> Ground
Blu ---> VFD Enable signal from Acorn (may have to configure from Acorn relay)
Grn ---> Estop from Acorn
4pin----Novakon BOB
R ---> 5VDC
Blk ---> Ground
Brn ---> Probe input to Acorn
I assume you have the automation direct VFD, which is already wired. (that would be the easiest) There is one end of the harness that only attaches to VFD. My VFD is a Hitachi Wj200, and I currently do not have jog control from the PDB. I am sure it can be configured but I had to get some parts made before I get back to it. (currently I have to line up spindle break disc manually to change tools)
I have been following your post as I considered the Acorn. I went with UCCNC because I previously installed it on my router and thought it best to keep the same controls. I like it better than mach3. However, the dedicated motion chip in Acorn should give you superior results. The cost is comparable, I should have gone this direction. (perhaps a future upgrade)
There is no dedicated motion chip on the Acorn, it is a beagleboard: BeagleBoard.org - community supported open hardware computers for making
The UC300ETH has a dedicated motion chip.
Thank you for the information, I went out and did a little reading. I used to use a Galil controller on my router. I assumed the acorn was similar but see that it is not. It appears the Oak controller may be similar to the Galil as it is closed loop in the controller. As well as addressing the issue I had with Gaili, integrating a software front end.
I think you have a problem understanding English, it is very clear on there web site that they are using a motion control CPU on there Board and it is 1Ghz :) the UC300ETH is only 400Hz, which is a huge difference in performance
Acorn utilizes an integrated 1Ghz ARM Cortex A8 Motion Control CPU, the BeagleBoard uses the same CPU and that is the only part of the BeagleBoard that is the same, this has been a Motion Control CPU used by many different manufactures because of it's ability to do a great job and is cost affected Motion Control CPU
And with my testing of the Acorn it performs better than the UCCNC software and hardware which I have also, so can do side by side comparison, Eding CNC is also ahead of UCCNC so there are lots of choices and there are other feature rich software and hardware that I will test and compare in the future
Having a closed loop system does not mean you have a better system, todays AC Servo Drives can close the loop just as well with less complication
That is a problem when using Gaili Great hardware but very little software support for machine control like CNC machines, Mach4 has just come on line for use with Gaili, one of the software engineer that works for Newfangled Solutions ( Home of Mach4 ) used to work for Gaili so may have perfected the needed plugin for the Gaili hardware, the mach3 plug had problems that was never solved
Yup Mactec54 I see you still have bad feelings about UCCNC because you have never described and likely connot describe what is better in those controls, it is just your little feelings again. :)
Arm Cortex A8 is not a motion control CPU, it is a general Arm microcontroller. The beagleboard populates that microcontroller. So you are again wrong.
Acorn did not even put in the effort to design their own motion controller, they just used a beagleboard.
At least all those other controllers having their own motion controller board designs.
