Re: Acorn CNC12 Mill, Router, and Lathe v4.64 has been released!

OK....I was hoping that someone had tried it already....guess not. Does Centroid have a position on CNC12 on Win 11?

Re: Acorn CNC12 Mill, Router, and Lathe v4.64 has been released!

Because as I understand it, Win 11 will only be available for free update for a limited time. Besides, why wait if it works?

Re: Acorn CNC12 Mill, Router, and Lathe v4.64 has been released!

Hi, I tried searching, but seems nobody ask....so here's my question, will windows 11 work with latest Acorn CNC12 Mill like windows 10? TIA I'm also interested in this, since my CNC router computer now says Windows 11 is available.......has anyone tried the latest Acorn CNC12 on a Win11 computer? ...

Re: New Build: SYIL X4 CNC Mill, Clearpath SDSK, C86ACCP & Centroid Acorn

Marty Sorry. I missed that when I first starting looking at this thread. I'm in the process of converting my mill over to Teknic ClearPath servo motors. I was motivated by struggling with missed steps on my Z-axis and your recent project on YouTube. Thank you. Britt If you are using Clearpath, you ...

Re: New Centroid Teknic Clearpath officially supported configurations

- the max current rating is for all the chip channels combined, the clearpath to Acorn is not using all of them so no risk at exceeding current ratings. - 1/2 watt 100 ohm at 5 volts runs 'cool', 1/4 watt will run hot (which is ok, just easy to go to 1/2 watt and not have it be hot) - the 5 volt 10...

Re: New Centroid Teknic Clearpath officially supported configurations

It seems to me that a 100 ohm resistor on a 5v system would have the acorn outputs sinking a current 58 mA. This is above the maximum stated in the Acorn user manual. Is this correct? Clearpath Input Current Draw.PNG Acorn Specifications.PNG Thanks, Clay This is what I'm talking about. First, per T...

Re: New Centroid Teknic Clearpath officially supported configurations

I'm still with Dave C's original concern about this. Many of us were wired with 1K resistors going to 24v, per both Centroid schematics and Teknic recommendations. Then, in recent posts, Teknic said that 1K was intended for 5v pullup, and that 10K should be used for 24v, mostly because of current dr...

Re: Lost steps newly upgraded machine <clearpath, resistors>

It's always best to ask. The manual that I have from Teknic also shows a 1K resistor, so I thought that someone just had a typo when I saw 10K. I assume that the manual was written for all users of ClearPath servos, so in actuality, it becomes the responsibility of the user to run some tests such t...

Re: New Build: SYIL X4 CNC Mill, Clearpath SDSK, C86ACCP & Centroid Acorn

Tom K, It comes down to the current rating of the resisitors. The 1k ohm resistor used with 24VDC at a high duty cycle could get warm to hot. If you have run your system for a substantial period of time and do not see any heat related issues with the resistors, you could be fine. That said, it woul...

Re: Lost steps newly upgraded machine <clearpath, resistors>

Mike, I understand the need for the resistor. My concern is that we were told 1K was the correct value for some time now, without any stipulation as to the voltage or heating. I just wanted to make sure that the 1K I''ve been using for over a year has not caused any damage to either the Acorn board ...
