    Re: Mazak VQC 15/40 Retrofit

    Hey Razvan,

    Seems like you have a lot going on. Overall the kflop is pretty good with only a few issues. I do on occasion have the konnects fault out and need to be reinitialized but that is due...

    Re: Mazak VQC 15/40 Retrofit

    Yea. The bearings can definitely take it. When I rebuilt the spindle I replaced the bearings with two pair of NSK 7014CTRDULP4Y. According to the catalog the 7014C bearings have a permissable axial...

    Re: Mazak VQC 15/40 Retrofit

    Hi Dumitru,

    Sorry for the slow response. Haven't been on in a while.

    The hydraulic cylinder pushes down on the fork end of the draw bar. This pushes down on the top of the spring stack. The...

    The wire to the shield is connected to the ground connections on the power terminals to the left of the board. Thank you for the suggestion. I will try to rig something up and connect the wire to the...

    Re: Issues with KmotionCNC

    Hi Tom,

    I'm glad you brought up the removable terminals. I forgot they slid onto header pins. Made swapping the two Konnects really easy. After swapping the two Konnects the machine ran fine for...

    Re: Issues with KmotionCNC

    I played around with the system today some more. I reverted back to 4.32 and am having the same issues with the gcode hanging on the M5 user programs. It seems to be a hardware issue as this is...

    Hi Tom,

    I've been having some issues with the new versions of KmotionCNC (4.33k and 4.33l) and was hoping you could shed some light.

    The problem I've been having with both 4.33k and 4.33l is...

    Re: Mazak VQC 15/40 Retrofit

    A member asked for instructions on how to tear down the spindle and get to the drawbar so I figured I'd make a post here that way if anyone else needs to know how it's done they can benefit from it...

    Thanks Chevy! Glad you like the machine.



    Thanks Feist. It is an unusual layout for a mill. It has a rigid design but the big downside is you can't have anything overhanging the table because...

    Re: Rigid Tapping in KMotionCNC

    Hi Tom,

    I never tried running the spindle as a true servo. I only tried running it in a closed loop setup to get better control of the speed but it was tricky to tune with the kmotion tools....

    I guess this thread wouldn't be complete without a video demonstration. Below you'll find a quick video of my machine rigid tapping 6 holes in a .250 inch piece of aluminum. The first 3 holes are...

    Re: KMotionCNC M6 Tool Change Issue

    Tom -

    Turns out that simply changing the M6 code to Exec/wait/Sync did the trick. Gcode runs perfectly now. Thanks again for your help!

    I did stumble across a minor bug however. I currently...

    From what I remember when setting up my system is that the console DAC command has no effect while the servo loop is enabled. Disable the axis then you should be able to manually control the axis via...
