The spindle: limitations? Precision, quality, matched angular contact bearings cost hundreds by themselves. plus then the taper (ISO30?) machining, heat treating and grinding, plus (presumably)...

Looks fantastic.

You're doing a great job.

Perhaps having an air hose periodically blasting the chips at some interval would suffice.

Great post. Definitely something that should be added to the Wiki.

Thanks for that.

Looks like we've got a similar pendant too - although mine doesn't have a nice terminal block like yours - just a mess of hand-soldered connections inside :confused:

I will be...

Are you able to share how you wired your pendant up?

I'd like to connect mine but I'd like to see how others have done it - I would definitely appreciate you showing me how yours is done.

Never did proceed.

I ended up buying a chinese 6012 machine made to my spec (3.2kw ISO25 spindle, 250mm Z clearance, C5 TBI ballscrews and Yaskawa Sigma 7 servos, MQL system)
Retrofitted with a...

Looks fantastic to me, great job.

One of my main complains with the KMotionCNC screen are those jog buttons - I've made my own GUI that's cut down on that, but it's only really applicable for the...

Hi All,

I've got many (over 5) machines running KMotionCNC, all under the control of one computer (not simultaneously).

I would like to be able to define multiple profiles for each machine,...

Hi all,

I have a project using the KFLOP that requires me to machine flat aluminium bonded to a circular substrate. The machine is a rotary-type router - where there is an A axis as a rotary axis,...

Tom,

I'm running VS2008 Pro and KMotion 4.33k (I had the same problem under 4.30 and 4.32).

I can open the BuildExamples.sln, but I cannot run it as I get asked to specify the executable file...

Hi Tom (or others),

I'm trying to compile Dynomotion_dotnet so I can create my own UI,

However, I have a lot of compile errors present. Please look at the attached image.


I would...

Usually a 10uF capacitor connected from the switch input to ground will also make the problems less apparent. You can increase the capacitor size, but you may experience a slower response to the...

You definitely want to shield it if you are playing with 5V logic. You do NOT want to connect the shield to ground at both ends as this will create a ground loop. Usually shields are connected to the...

The spindle bearings have been replaced with 7005AC bearings (my model is a BF20 - has a MT2 spindle and needs smaller bearings) and the top bearing with a better quality unit.
I've run the thing...

Looks good.

I had the 1800W one (M06030) on my G0704. Had 5000RPM at max speed with a 60:36 tooth HTD5M pulley arrangement.

The spindle ended up disintegrating (it was defective...

I was aware of the features before purchasing.

The reason I asked was to compare your conversion to my factory model. It seems that you've achieved the same performance as mine.

Sorry for my brash description.

Does the stepper run quieter than an open-loop counterpart?
I have a 4.5N.m. closed loop NEMA 34 stepper with the same drive (I believe - a 2HSS86H) and it is...

Interesting.

Do you know what benefit closing the loop on something like that is?

And what is that horrible noise that occurs in the first few seconds of homing it?


Otherwise, pretty cool...

I've got a Hertz 2.2kw spindle.

It is fan cooled, and uses a junction box with a fixed cable on it.
I have since replaced that junction box, and put in an IP67 connector to allow for quick...

Hi Tom,

I will use KMotionCNC. I want absolutely nothing to do with Mach3 - it's caused me far too much grief in the past.

I can make the button array myself, and have each button as a separate...

Hi all,

I'd like to use a Kflop+Konnect for a new router I'm building, as I've had success with the Kflop in the past.

However, something I believe is missing (not from the Kflop, but PC-based...

The only downsides would be the risk of destroying something in the event of a crash, and lower top-end speed - the torque of those big steppers drops off rapidly.Have a look at this graph:...

Nice job.

Your choice of a 1200oz/in stepper is insanity to me though - you'll be getting over 10kN (1 metric tonne) of force through your axes.

IP stands for 'ingress protection' - first digit is protection against objects (fingers, dust etc), second digit is protection against water. IP6x means absolute protection against dust, but an...

For anyone interested, I received a quote for the stress relieving: $180AUD for stress relieving the gantry at 580-620 degrees celsius for 2 hours. Doing the same operation for the table and gantry...

Attached is the manual for the servo drivers - if someone were able to interpret this in a way I could understand it would be very, very much appreciated.

I think that the deadband function is...

The servos were not tuned from the factory. On first use they were extremely laggy - I could rotate the shaft by hand quite significantly before they would decide to respond. So I turned the gain up....

I suppose the main reason I'm avoiding a PC-based controller is that I want IP6x rated physical buttons to play with. I do not want to click on-screen buttons with a mouse.

As for why I'm...

I understand that the resolution might be low, but I am really not interested in a PC-based controller.

These controllers are in use in thousands of existing machines. Comparing awful Chinese...
