    Exclamation Need some help with a new Omni 1325 with DSP A18

    If you've dealt with Omni, you know just how frustrated I am. End of rant. I have many questions. Anyone around the Columbus, Ohio area? I am willing to travel, email, skype, facetime, telegraph or use semaphore flags.

    The free Alphacam DVD is blank. Every install of the Ucancam comes up with a corrupt .dll file. Can"t use it on my new computer because it only has USB-C and the old school dongle is USB-A. It won't recognize it through an adapter. As a result, I have no software and don't know what files this thing reads. Leftover files in the handle are .nc. Omni postprocessors in Vectric show .tap files.

    I'm getting errors when trying to run a file still in the controller memory. When I ask Omni four questions, I get one answered with info that doesn't help. Example: plugged in the water pump and it doesn't work. Their response: send me a video of a pump that actually works. So now I'm going to show that video to my spindle and see if it keeps it's cool. Anyone care to lend a hand? Reply here or message me please.

    Yeah, my Alphacam software was dud. I don;t think they are legit copies at all. I would try Vectric, user friendly and good value. There are post processors elsewhere on the forum, and these will create .TAP files for your machine. Hopefully your machine is up and running, post again if you need help.

    Not sure what sort of issues you are having WRT your description but here's a few comments FWIW.

    The A18 DSP is a standalone control and can not be connected to a PC to control the CNC machine. It operates in one of two modes being CNC control mode or USB memory "stick" mode.

    1a. Power it up while connected to the CNC machine and it controls the CNC machine. It can read/run files in internal memory (called "inner") or from a USB stick (called "outer")

    1b. Hold a panel button (say the "OK" button) and power up the CNC machine and it starts in "USB memory" mode. This mode sets the DSP to appear as a USB stick to a PC and you can transfer files between a PC and the DSP but can not control the CNC machine
    1c. See 2c.


    2a. Leave the CNC machine switched off and then connect the DSP to a PC with the USB cable. It will start as above in CNC controller mode but no machine to control

    2b. Hold the "OK" button and connect to a PC, if there is a USB stick in the DSP, it will connect it to the PC
    2c. Hold the "OK" and the "CANCEL" button together and connect the PC and it starts in "FLASH" mode - this accesses the inner memory to the PC as a USB memory stick

    For 1c and 2c, you can read/write files to/from the DSP just like a USB memory stock.

    When trying to run a CNC file in the DSP as a controller, it parses the file first and for any codes or file types not configured/understood/supported it throws an obscure message.
    Often this is the initial setup codes near the file header. It may also be that it does not understand the file extension. Try using just an ".NC" extension first as per the "leftovers" you mention.

    Go through the DSP internal machine setup settings and verify they are set up properly for your machine. If they are correct, get a backup of the settings and store them safely for future reference.


    Try a simple file such as the following to see if the controls function. The key lines here are N60 and N70 to set the machine state.

    This code will cut a square at 100 x 100 mm and a circle centered inside it at 50 mm diameter.

    It is important to "HOME" the DSP on power up otherwise the DSP won't know where it is but will know where the last G54 work co-ordinates Zero positions were.

    Watch out for your co-ordinates and settings to avoid any crashes. Try an air-cut first!

    The below assumes the X, Y positions are lower left zero and Safe Z is at +50mm from the work-piece top surface.
