  1. Re: starting my C program, any guidance would be apreciated.

    I'm guessing whatever is causing the problem, is then triggering an EStop in the KFlop, which will trigger an M5 (spindle off), so that message is just a symptom, and not the problem.

    Is it the...
  2. Re: starting my C program, any guidance would be apreciated.

    What have you got setup for the M0-M30 functions in Setup?

    That jogging stop message is from the C program to stop the spindle.
  3. Re: starting my C program, any guidance would be apreciated.

    That tells us the G-Code file itself is fine. If you were to open the G Viewer, you should see the simulated motion.


    If you open KMotion (not KMotionCNC), there is an option to display the...

    I've just had a skim through this thread, and it appears you're just randomly changing things to try and get things to work.
    So lets take a bit of step back, and work through things a bit more...

    Re: Check Position M6 Tool Change Code

    I've just checked my toolchanger code, and it has no check as well.

    Tom, if there's no encoder, could the axis destination be used?

    Re: Lagun FTV3

    You need some way to disable the servo drives/amps when they are not being controlled by the KFlop, as it sounds like the drives are still powered up, and are drifting.

    Do the drives/amps have an...

    Re: Lagun FTV3

    Limit switch options are on the Config&Flash screen, which ultimately transfers them to the channel config.
    Remember you need to download/upload the channel for settings to take effect.

    In that case, is there no adjustment on the power supply?

    Most power supplies have some form of adjustment.

    Re: KFLOP & Mach3: Configure STEP PER

    The reason I asked about if they were genuine, is genuine DM drives (and I'd imagine direct copies) need increased pulse widths, so you have to add an extra line of code to the KFlop configuration,...

    Re: KFLOP & Mach3: Configure STEP PER

    I would not run at 128 microstepping.
    Once you go above 8 or 16, there is no noticeable improvement to be had, and you're far more likely to have issues due to the high pulse steps involved.

    Are...

    Re: Hurco BMC20 Dynomotion Retrofit

    Just had a quick search, and this is the kind of valve I'm thinking off - https://www.airlines-pneumatics.co.uk/pneumatics/valves/flow-control-valves/flow-control-valve-in-line-type-push-in/S070132...

    Re: Hurco BMC20 Dynomotion Retrofit

    Would the original valves not have one way restrictor/flow control valves, so the non-pressurised side return/vent flow is restricted, and acts as a buffer against the pressurised side?

  17. Re: Intro questions - Windows/Kflop/Kanalog and a 17k pound milling machine conversio

    The KFlop has serial ability as standard, however the pins used don't meet the full RS232 standard. However if you add a Kanalog board, it adds the needed buffer to get full RS232 voltage compliance....
  18. Re: Intro questions - Windows/Kflop/Kanalog and a 17k pound milling machine conversio

  19. Re: Intro questions - Windows/Kflop/Kanalog and a 17k pound milling machine conversio

    What I like to do with any new retrofit, is make a spreadsheet that lists all the inputs/outputs needed, along with how they work (i.e. switch to gnd/positive) what voltage they run at.

    That is going the correct direction, but obviously still needs work.

    I wouldn't give up just yet, especially since you were making progress. The reason there's not really a guide to follow, is the KFlop has that many options, the guide would never cover all options.

  25. Re: KANALOG TO MACH3: FRO POT, MPG, Z encoder INPUT AND CODING

    The ADCs don't have bit numbers. Bit numbers are only assigned to inputs/outputs that are digital (aka are only ever On/Off).

    To access the ADC's, within a C program, you use either ADC(x) where x...

    I'll clarify this a bit for you.
    Although the motor has a 16bit encoder, it is an absolute position encoder only getting sampled periodically by the DYN4 drive. The DYN4 drive then takes that...
