Got it, it works. It shuts the machine down 10 seconds after I leave either Mach3 or KMotionCNC.

So, I am trying to get Mach3 configured. All the axis are moving, estop works, coolant works. But...

I like option 2. Thanks

Ok, I tried it again and it does work now. I must not have reinitialized when I edited it before.

While I have you here... So I use bit 63 to turn on the main contactors for all the servos and...

I did try that and it did not make a difference.

So I tried manually doing a SetBit and ClearBit on 15 where the dir line to the servo connects and it does not change state, is this because it is tied to the step generator? Do I have to use an...

OK, it spins. but in the same direction for M3 and M4. What do i need to change to activate the dir bit?

Thanks, I will give that a try.

The spindle is on Channel 3 and I set up Velocity and Acceleration and tested it through the KMotion app and it does respond. I am just not sure where to go from here. I am initially setting up with...

So, after 2 years of having a kflop and konnect setting on the shelf I finally installed the thing this week. Got XYZ working but I am not sure what to do on the spindle. I am using a 3.5kw...

Wednesday night I decided to dig in. My goal was to finish it by sunday as I need it for work this week. I put it on rollers and slid it away from the wall.

Thursday I gutted the machine. Pulled...

Its been about 5 years now and its been a good mill. A few little quirks. If you powered up the servos with the drives enabled it would jump and sometimes fault out or trip one of the breakers inside...

The belt is not the issue with the surface finish, Monarch lathes use very long belts to drive the spindle specifically to isolate gear noise from the spindle. I have tried those power twist belts...

During the thanksgiving break i actually made parts with the lathe that are functional. Woo!

Here is a little video:

Hi, we have a Flashcut 8300 that isn't being used and we are looking to get rid of it. Has the servo option and the software is a few revs behind. Basic router spindle too. Has visualmill with it.

Just replace the bearings with what were in there. Unless you want to get into trying to figure out preload and all that fun stuff. Then I would go with angular contact bearings since they will be...

We are adding a second gantry to our DynaCNC table. Anyone know what truck model they used on the linear rails? All I can see is HG25 on the plastic wiper.

Almost done! The front panel is finished. The pokeys works really good. The keyboard matrix function works great. I pretty much used up every IO on that board. The MPG does not work great. They are...

Yep, had one of those drill presses. Did the same thing. Another thing to watch out for is the depth stop flexes and is not repeatable.

They are good for plastic and wood, otherwise you really...

Yep. Support seems to have died for the smoothstepper and there is still no backlash comp available. Until that happens I am using the parallel port. Everything is done with a single parallel port,...

Made quite a bit of progress since the last post. Got spindle indexing working. I am currently using the index pulse out of the 2500 line encoder through a 555 one shot timer to get a pulse length...

Have you ever made patterns before? Its not as easy as you think. We offer patternmaking classes where I work and it takes a lot of time, skill, and knowledge to make a pattern that will actually...

You have .001" Runout in your spindle?

Yikes!

You dont know if your spindle is even holding the er-20 holder straight at this point.

The collet is garbage. Send it back or throw it out.

Pacific Science also made these motors: http://www.pacsci.com/

Also Magnatek made some.

I am running the MR-J2. I have a J2S and have popped it open and the input circuit is virtually identical, just slightly more modern version of the components. The pins on the 3M connector feed...

Got the tool changer going. Used a ModIO from http://www.hommandesigns.com and Peter made custom firmware to drive it.

Here it is cutting 6061 and making a 1/2"-13 thread. Sorry about the focus...

If you put a 24v signal directly in to the step and direction pins you WILL fry the input of the drive. I know. I found out the hard way. You can send 5v right into the step and direction pins. My...

Heres the one mactec54 is referring to, the YAPSC 10V:

Open source so you can build them yourself. That will prevent what happened with the...

I would say the microswitch that senses locked position is bad.

Thanks guys. This thing is taking me way longer than I thought it would. And this is not the first machine I have done! I think it has a lot to do with me trying to keep everything as original as...

70A drive is a 700 watt (~1HP) drive, not 70 Amps. That would be a monster!

You know, that sounds like tuning issues. Excessive friction causing stick-slip. By sending a pulse train to the servo...
