Just to follow up, yep the last 2 bits of parameter 3 are the ones that control metric/inch and "ten thousandth" vs "inch" mode. Flipped it to one and the machine is working great. Thanks OkumaWiz!

If you have something at home that would be great! I got a bunch of manuals with the machine but mostly loose pages and very little in terms of parameters and control functions. I've had this...

It's not that - I tried it - if I type G0 X10. Z10. it goes to X 0.0010 and Z 0.0010

Also the programs I've been running forever are crashing into the work :) So something definitely changed.

So in case anyone comes across this later, I figured out what is happening...

if I type G0 X10 Z10

It is going to X 0.001 and Z0.001

The machine is in "ten thousandths" mode instead of...

I have an old LC40 we don't use too much except for a few jobs... hasn't been run in a few weeks. I turn it on, load up material, set my Z offset and hit go. Spindle doesn't start, and the tool...

That worked, thanks!

Do you know if there's a way to capture points only when they are on a plane or within a tolerance value? It would be nice to be able to move around the perimeter of the part...

I have a MicroScribe digitizer. I am trying to model the outer perimeter shape of a part so I can cut a recess in another part to hold it. The errors inherent in the digitizer and my hands produce...

Thanks for the info Matt.

Can you point to any laser power meters? I am not that familiar with them - I've seen very expensive units in the past, but way more than a machine owner would spend to...

Melody,

Can you give an example of the price of the RECI tube and the RF tube for the same wattage?

What is the expected life span of the RF system? And what (if any) is the warranty?

I...

Just curious about something....

It seems that the major difference between the Chinese/US lasers is that the big US companies like Epilog/Universal use RF driven CO2 lasers, whereas the Chinese...

This isn't strictly a CNC application.... but...

I am trying to make a sort of motorized wheeled robot that I can quite precisely control it's speed and acceleration.

I do electronics design so...

Mine's quite a bit different than that - it has the gauges up top and a lot more switches, plus more buttons in the panel to the right. Here's a pic of mine.

Interested to learn about what...

I wonder of Okuma built machines very differently over the years?

As I mentioned in my previous post, I don't have a parameter screen for chuck/center work. I have a switch on the control panel...

I don't have a screen for that - I have a key switch on the control that lets me select between center work and chuck work. I took the back panel off and tested that switch to make sure it was...

I am not sure exactly what switch that is... I have a row of 3 adjustable pressure switches, and a push-button that reads out the pressure for that circuit on a gauge. I adjusted the tailstock...

I am not seeing that.

I press "Parameters" on the control, the first screen has (each of the following has a space for XA ZA and C).

This machine is driving me nuts lately.

I was running parts all weekend and all was fine. Running parts today and I hit cycle start and it alarms with Error 140-2 "Tailstock spindle condition...

The servo drives you mean? When I was doing Google searches, there were tons of places that will repair them... but they want $1000 or so for the job. I can buy LDU-600's on Ebay for $400-500 or...

I have a late 80's LC40 with two turrets and live tooling and a tail stock. When I got it the smaller turret would not move in X, only Z... and the former owner told me the Okuma techs came and said...

Ended up being a relay after all.

There are two that operate the chuck, one is "chuck open (command)" and one is "chuck open". I guess one just sends the signal to the control, the other does the...

Well, when the spindle refuses to start, I can click into manual mode and jog the axes fine. Actually the first thing the program does it move the turret back, then start the spindle... so the...

I have an LC40 and last week I was running parts and after a couple of hours of cranking out parts, I load the next bar and hit start and the coolant turns on but it just sits there.

Hit reset,...

Anyone else got one for sale? I haven't heard back from Larry... wanted to get one ASAP - couple of dealers offering "recertified" ones but I think they just say that and mark it up :) Would rather...

Hi Larry,

I sent you a PM, I hope we can work something out. Thanks for your time.

Mike

Looking for a 3D digitizer in good working condition.

Anyone got one for sale? Doesn't have to be Microscribe, but that's around my budget.

Just about to buy a used model from a dealer but...

That worked!

Thank you, especially for the example - it helped a lot!

Thanks for the help.

The Solidworks file posted above is pretty close, I will give that a shot.

Emonje, if I was to add "ribs" between the perimeter and the "backbone", what tool would I then...

I have a part I measured using a probe (the spline shape in the first image).

So I need to model a "domed" top surface so I can machine this part - it will end up being a cosmetic cap that covers...

You can get a special spindle that goes in your regular spindle and has very high RPM's.

Air spindles are cheaper, but use a lot of air - they come in electric too. I've seen 50,000RPMs.

Hi Al,

Sorry, I wasn't clear in my previous post. When I was talking about a gearbox if I don't use a stepper, I meant a DC motor feeding a gearbox and "something" for feedback (either an encoder...
