Ive read all the posts on this forum. I bought the 8g 2.0 and formatted them still got the "cant read message". Bought the axiom drives (2) and still get the message. Use the safety to remove them from computer. same stick will work one time and not the next time. Can make them work sometimes by cycling the pendant to internal and open something on it and then closing that and then go back to USb and its there. Guess I can shut off the machine and restart but then you have to zero out everything again. I think the USB port on the pennant is the issue. Any suggestions?

Petercoe, I have only had a file not found error, and it was when I either swapped the usb drive or thought the file was on a different drive. I found that I was either confused or I confused the black box. The rich controller I think was looking for info or locked. Possibly (human talking to black box and box not listening or black box not telling human what it wants) either way I stopped load and canceled it then removed usb drive (waited very briefly ) reinserted drive and continued to reload. It worked ! My problem or remedy one step back (reset) then continue forward for more cnc carving. One question does the drive show files on it if inserted into your computer if so and reinsert after cancel load does not help --- then time for Axiom Support Help (but try only one drive at a time and reset remove reinsert and load file) good luck Happy Easter!

Are your file names over 6 characters in length?

I think I have a related question. If I start a project and once the CNC stops I pull the USB drive, update it and reinsert it in the controller, it doesn't seem to update unless I power cycle the machine. Is there a way to force the controller to read the stick again upon plug in without having to power cycle?
Thank you

I never remove the USB stick without turning the machine off, nor do I "pull" it from the computer without going through the "eject" process first. By "update" do you mean it doesn't see new files that you've added? If you modify an existing file and save it with the same name, then that file won't "update" to the controller if you've transferred the file to the controller from the USB...you'll need to delete it from the controller and transfer it again. I always load files from the USB to the controller before cutting. I know some people don't, but I see it as less of a chance for communicaton errors.

I do the proper eject process from the computer, but I have yanked it out of the controller. I agree with your comm suggestion, although I was following the printed guidance that suggested anything over an hour be copied to the controller: everything else I have run directly from the stick. And what i meant was: I run a tool path while still finalizing the next path. When done, I pull the USB from the controller (without turning it off), plug into the laptop, write the additional tool path (different name), eject and then plug into the controller. It will not show the new toolpath unless I power cycle the controller. It's a minor hassle. Love my new machine Tim

It may be that removing and replacing the thumb drive in the same session is not doing anything to trigger a "read", so the machine controller "thinks" that the last information it retrieved is still valid. You might try this: After replacing the thumb drive in the machine, select one of the files on the USB that the machine "knows" is there and copy it to the controller. You don't need to run it, and it's easy to delete. Then go back to the USB and see if it updated the file list that you see there.

I use the same method as you dustypilot. Unless it's a larger file, I just run from my flash drive. I use an old USB 2.0 2GB Flash Drive. I run a file then pull it out with the machine still on, update the file making sure to select yes when windows wants to overwrite the file that has the same name, then plug it into the machine.
The controller generally reads the USB stick fairly fast once you insert it and hit the green button to bring up the run menu. Never had it not read or mess up during a run (unless it was a large file and I was running directly from the USB vs. internal memory).
Just to note, I've never used the eject method when removing from my computer either.
I'd say when saving the file, it isn't overwriting your previous tool path. When you transfer a file with the same name from USB to the controller internal memory, it will overwrite it as long as you click the ok button.
I wouldn't constantly turn the machine on and off throughout the day when you need to remove the USB stick, power cycling constantly doesn't seem like it would be a good thing to do. Just my opinion.

In 4+ years, I've never transferred a file to the internal memory of the controller and I've run up to 17 hour toolpaths. I've also never used the eject method on my computer. I also routinely swap USB drives in a session. Now this is occasionally a issue, but I always eventually get the controller to read the new drive. Usually this involves removing the USB drive and reinserting it.
All that said, I did have to replace the controller early this year.

Hey guys. I’ve had the same issue come up also. I’ve found that my controller likes Sandisk drives for some reason. I can take them out update a file and insert and run updated file no problem. I also use Kingston drives also but controller only likes them from power up. If I try updating a file and inserting it I have to power down and restart machine. My other CNC machine likes the Kingston sticks and doesn’t like the Sandisk at all. I’ve found this out by trial and error. Just my 2 cents worth.

Bit of a mystery going on as my AR8Pro likes Kingston drives just fine and I can swap files in and out no problem and no restarting required, it may just say reading flash for a minute
