    Default multicam 3000 - running cnc without controller

    We have a Muticam 3000 CNC router that we expertise for research and educational projects. As most Muticam products the machine is always busy. Two days ago we had an unforeseen mishap when one of our trainees dropped the CNC handheld controller. There is no display on the KDM-20 controller (see attached pic- keypad.jpg)multicam 3000 - running cnc without controller-keypad-jpg.


    I opened the controller and the problem seems to be damaged circuitry.
    We contacted our local agents and placed an order for a new controller however there will probably be over two weeks of down time on the machine until we get the new controller.

    I have a basic understanding of electronics and I’m persistent to try to make the CNC operate without the controller as we just cannot afford the downtime.

    Proposed solution: I discovered that Multicam suit 4 has a keypad emulator. If the keypad emulator works then we would have a temporary fix until we get the replacement controller. I opened the program and it had connection issues(see attached pic- keypad emulator.jpg).multicam 3000 - running cnc without controller-keypad_emulator-jpg


    I then opened motion mechanic program, and I realised that if I restarted the CNC, the motion mechanic dialog box displayed what the keypad controller used to display (starting details of CNC, enabling of motor drives, faults, etc). The dialog box passed all the test except it reported a fault (error A1) which I presume is the controller(see attached pic- motion mechanic.jpg). multicam 3000 - running cnc without controller-motion-mechanic-jpg

    I also assume that the CNC during start-up test identified that the keypad controller was not working and populated an A1 error code. This is probably why the keypad emulator was unable to connect as the CNC identified a keypad error.

    I also discovered that I am able to reboot the CNC using motion mechanic/live update(see attached pic- live_update_reboot.jpg).multicam 3000 - running cnc without controller-live_update_reboot-jpg

    This proves that I can control the CNC to a certain extent. If I was able to disable the A1 error then maybe the keypad emulator would work. This probably would involve modifying the CNC start-up test to disable keypad checks. Maybe “ini_selftest” (see attached pic- machine update.jpg).multicam 3000 - running cnc without controller-machine-update-jpg

    Please help, and I hope im moving in the correct direction.

    the motion mechanic screen you posted shows no errors, not sure if the keypad simulator was actually meant to run the machine. The handheld controllers are pretty sturdy, did you order a cable at the same time?

    Pff, I wish.

    Anyone got insight on this? Same situation as @ugan.git as the controller screen wen't dead. I can control the machine out of my memory but would be nice to have visual feedback on things.

    Did you get rid of the A1 error ugan?
