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...

Sure. I'll measure them tomorrow when I'm in the shop.

Those holes are used for coupling the two spindle shafts together. if you scroll up to post #39, looking at the 3rd image you'll see the hex screws that hold the two shafts together. Torque is...

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...

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...

Hi Tom,

Thanks for the input. I don't know where to get shielded ribbon cable either but I happen to have some braided copper cable shielding from a cable I took apart when removing the old...

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...

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...

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...

Here's the page that you'll probably be interested if you haven't found anything yet.

Hope this helps.

Mill has been up and running for a few months now but I've been way too busy to post all of the things I've wanted to but I'll post some quick photos of the machine mostly assembled as well as a...

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....

Thanks Eric. I hope this helps you in implementing rigid tapping on your machine.

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...

Every machine spindle has its own set of physical characteristics and no simple, universal equation can define its behavior. In my machine the spindle is controlled via an open loop thus having...

I came across this thread https://groups.yahoo.com/neo/groups/DynoMotion/conversations/topics/10116 on yahoo groups and noticed you guys were trying to get a working C program for rigid tapping in...

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...

Hi Tom -

Thanks for the fast reply. I really appreciate it. I'm glad you brought the "Exec/wait/sync" option up because I did not try it or think to try it until I was writing this post. Also am...

I'm having an issue with KMotionCNC running code past the second tool change. The first tool change is performed and KMotionCNC continues to run the gcode and then the second tool change is performed...

Can you explain the procedure? I have the password but don't know where to enter it.

The sleeve is precision ground on multiple surfaces so it would be tricky to make. This part is the reason I needed to buy another spindle. If you look carefully on the 5th picture you can see a...

Pictured below is the spindle drawbar without the belleville spring washers installed. The belleville washers it requires are 20.4mm x 40mm x 2.5mm, 24 sets (48 total). The washers are doubled up so...

Sorry for being MIA. I'm on the home stretch with finishing the project. I have painted all the panels and the machine and will be reassembling the machine soon. A lot has happened since the last...

Unfortunately the Mazak wiring diagrams did not include the internal connections between the controller and the servo amps. Luckily I found this thread...77549 Mitsubishi TRA41 Servo Drives Interface...

A picture will help. Problem is that on my tacho wiring setup it was 3 pairs of shielded wires. Each pair has a red and white wire so there are 3 red and 3 white wires total (essentially the same way...

I decided to replace the resolvers with high count encoders to make it easier to send position data back to the kflop. Unfortunately the hole where the resolvers mount into were to small so I either...
