I have, though by the time I leave it's probably down to 2 or 3 hours of run time, since I don't have an ATC and can't leave till it's on the last tool. I'm totally confident in the controller and...

You'll have a rough time trying to machine those jaws. I have no idea exactly what steel or hardness they are, but its 'hard'. I suspect you'd want to grind that step, if you had your heart set on...

The ways to accomplish this in one setup are pretty unattractive. As you've noticed, you need a very long tool with a relatively small diameter, and achieving a smooth finish will require very small...

Is it possible that the stock is pinching the blade? Also, what speed range are you in? It's surprisingly easy to stall the spindle at low RPM if you're using the high range pulleys.

Normal shutdown procedure is to E-stop the mill with the big red button, then close mach3, then shutdown the PC, then power off with the disconnect switch on the side of the cabinet. This ensures...

There could be a lot of things going on.

The fact that you're having issues on all three axis suggests it's not an issue with the gibs/nuts/motor drivers, but something either with the power...

I suspect that if you're new to machining the grade of ballscrew is not going to be the primary issue with machine accuracy. There are many other things working against a small machine like the 440...

PP has a couple really big one ups over mach 3, in my mind.


Soft limits; this saves me so much time during setup of large parts. No more bumping into the limit switches and having to reref!

I've found ABS to be an unpleasant material to work with. It just gets really stinky. It's easy enough to machine, and cheap, but ugh, that smell!

My experience with Gwizard and its...

Just an update- I haven't included the changes for the comment or original feed format, but did get a chance to test out the code generated by the modified tapping operation arrayed using HSM's...

Now we're getting somewhere- thanks for posting this!

Unfortunately I can't get it to work as is and my understanding of javascript is pretty limited. I've made some edits that seem to make things...

Alright, so here's something I can't find a straight answer to;

I make a tiny little plastic part that has a 0-80 tapped hole in it. Normally I tap these by hand but now I need to ramp up and make...

It's funny what 'cold' means to different people. My shop was below zero much of this past winter. Besides wiping the ways down as best I could with light oil every day I didn't do anything different...

It's the middle of the night. The mill makes an awful racket, and the rest of the household seems to like sleeping when it's dark out. Go figure.




Sure. There are also a lot of people who...

I can't speak to the providence of the table you've gotten, however, I can offer an anecdote from my own work experience.

I worked for a company that produced injection molded parts in China. Our...

This sounds like a reasonable plan. As has already been suggested, check your travel extents very carefully. Even if you're comfortably within the axis limits the beam may translate right into...

Yes and no. The design is such that it's largely sealed. I suppose you'd call it splash proof, not water proof. I have noticed since my work switched to primarily delrin that some small chips are...

The DC bus board has a fuse for each 'output' and one 15 amp main fuse, F6. If the board isn't producing any DC voltage, that'd be the first thing to check.

It does sound like the meter still set...

My understanding (and I'm no EE by any means) is that the part in question is a simple linear transformer with no regulation. So output will vary with input voltage but I somewhat doubt it will sag...

I'm assuming your working with a 1100; I'm not familiar with the 770 and I wouldn't assume they use identical control electronics (though there may be similarities).

Which transformer are you...

It it makes you feel any better, the username is actually Moggot. Expectations are a funny thing, everyone makes that mistake.



I haven't looked at that sort of thing in a long time. My...

I'll also chime in that Mach three has never been an issue for me, either. There are enough complaints from smart people to make me think that issues aren't always entirely a user error sort of...

Hi Metalshavings,

Mach3, at least the build that runs my series 3 1100 which, I believe, is the same or similar as that for the 770, does record a variety of usage data. Select 'Operator' from the...

In my case the building I work in doesn't have adequate compressed air for a PDB, and my neighbors disapprove of an air compressor generating even more noise (acoustic and electrical) then the mill....

This thread reminded me of a tormach blog post I saw a while back:

[url=http://www.tormach.com/blog/soapstone-machining/]Soapstone Machining

Out of curiosity, what speed range are you in?

The 1100 has two ranges selected with a belt. The high range allows between 250-5140 RPM, and the low range 100-2000 RPM. The overlap is convenient...

For FRC purposes I've always used a normal circle interp roughing/finishing process. With good tooling you shouldn't have much trouble getting a reasonable fit. Retaining the bearing in a slightly...

I'd suggest you read the Tormach design paper on the Series three upgrade. It's well written and really goes through the thought process and rationale for the change. From the introduction:


...

Outstanding! Nothing quite as satisfying as getting a job dialed in and hearing your mill hum along making chips like it designed to.

Couple points:



You're correct that stickout is defined...

There's probably a dozen ways to do this, and which is 'better' probably depends on a lot of variables. The real answer is whatever option gets you the part you want, and since there's more than one...
