what is the feed used in the video. im also assuming the video is being speeded up and not real time

also how much do you charge for that

do old fashioned imprint the cast

any mill can do this. you just need to create some fixtures to hold sheet metal.

the method is called single point incremental forming, look it up.

essentially you run your rounded hardened...

You make a contraption that is designed to generate cyclones, essentially a fluid dynamic centrifuge, and then throw some kind of holding forces into the system (often just gravity if you create a...

How long do your (expensive?) tools normally last you when maintained well?

Ive had hits and misses with cheap tools. I also have expensive tools but the cheap tools seem to work fine most of the...

I know the feeling. The plus side is there is always something in the horizon so you are never dry of ideas to do, but it does get frustrating if you are backlogged.

Yeah it is a pain. The other...

Im sure there is always an optimal cost-benefit sweet spot for everyone on their indifference/utility curves for purchases.

Im actually just wondering where are some of the 'go to' places for...

Prior to deciding on recycling, did you also consider even remotely, casting a new block of now unknown purity material from the chips?

I use linux too. Its just that my commercial CAD and FEA software are windows based so it makes it a lot easier to design in CAD and then quickly transition to heeks and get the gcode instead of...

Most people buy locally so your shop has to be in a location with sufficient demand for raw materials. Alternatively offer low cost shipping, but that is often out of your control via couriers and...

Where are the best/cheapest places to buy ball screws, linear bearings/rails, etc?

I wasnt speaking about noise from the steppers while it was moving at low RPMs. I was speaking of the idle noise as well as the intermittent squeak at then end of movement.

Things are not wired...

Do you even throw your pop cans and other household disposable aluminum in the mix or do you let the municipal services take those for recycling the old fashioned way?

Yea its a good idea. Maybe...

Wow 700 bucks is good return! How did you find out about the place? Just drive up to the local scrap yard or recycling plant? Also, out of curiosity, do you run a home shop for hobby or business? How...

I guess you got hookups for recycling locations but do most recycling places take scrap? Theres a scrap yard here but I dont know if they take scrap chips? They probably dont mind taking for free but...

The high pitch 'whine' is a more accurate description. Its a short pulse. High pitch. Right at the end during the stopping/deceleraton. Analogy is squeaking sound of metal fork on metal plate.

Im...

Ive wired them pipolar parallel already. Its quite loud and Im not even being picky. My old steppers you can hear some noise while idle if you put your ear to it. These ones I could hear from across...

I have a gecko g540 with new steppers. They are buzzing while idle quite audibly. Also, when jogging the axis and then stopping, sometimes there is a high pitch noise generated.

Im wondering if...

I was wondering if anyone can tell me what is their G540 settings for running in EMC2?

They sometimes have not up to date timings in the default settings. To be sure Id rather do it manually. For...

I dont think I read anywhere on the manual addressing whether or not it is ok to crank the handwheel when everything is plugged in (but power off to the G540).

Is it ok or do you have to unplug...

Anyone do their part to save the world by recycling metal chips? (I presume it may include having to sort out the chips (i.e. clear the collector between different runs of different materials) and...

LOL. I wish I had a better budget too!

Some of those medical device manufacturers use micromills or other people use in R&D settings like @ universities etc.

What features is it that you are talking about?

I know of a company that...

Yeah tools on the Z axis for turning with a mill is best.

You mean servo for rotating the part instead of standard DC motor? Is it better because its better for say threading or something cause...

Yeah a collet is better, but then you are limited in size of the part.

Has anyone tried making their own ball screws and nut?

Is it possible to make the ball screw using a 4th axis system, and then say rotating the spindle holding an end-mill of the correct diameter...

Look for those insert catalogs, they often explain the nomenclature of the inserts and their geometry and differences. Most common inserts have ISO and ANSI standards for them.

Im looking into...

What is the smallest size feature that has been achieved using a CNCed mill? Yes, of course it depends on machine rigidity, material rigidity, vibrations in general, cutter diameter, spindle runoff...

First you need a CAD program, which is for designing whatever it is that you want.

Then you want to get a CAM program, which transforms your designs into gcode.

Most people tend to find their...

Not that I was speaking from experience or anyting. I never usually tram my mill before every job because I havent done any 'precision machining'. I mean it seems possible for some machine to lose...
