How does your mill table look now?

It seems Tormach is making it's way into the large companies. I have seen multiple images of the PCNC on Ge Garages, Check out the background.

Has Tormach make you exchange the transformers in there? If not, measure the voltage if you go full power, so under a condition that causes the "thump". You might loose voltage when they are under...

I had the same issue in the past. It was a loose connection between the printer cable coming out of the PC. Alternatively check the connection cable to control case. The control board needs a live...

Check

1. Whether all ball screws are lubricated. If you wipe across them with a finger you should have a light oil film on your finger. Might sound ridiculous, but is a maybe. What lubrication...

Check whether all your boards are grounded and d-check the ground wiring. Also make sure you use the short, shielded printer cable. I would guess that you have some noise in the secondary circuit.

Well,

I would be the happiest person on this forum if making a machine like the PCNC_III for 6.5k in the US was a realistic option. A precision machined casting of that size (base, table plus...

well, I am not so sure about that... If you live in the Dollar zone, the face value...

Well, you have to adjust prices every once in a while. With the Dollar taking a dive into the abyss, the margins are being squeezed for imports. I can fully understand that move and it makes sense to...

I could not agree more. But you have to accept one basic law of the shop floor:

There are only two types of machinists:

1. those who have run into the mill table
2. those who will

There are a multitude of opinions about milling vs. Drilling holes. Here are my two cents:

1. If you mill out a hole you will always have a slight taper in the hole because of the mill bending. It...

Our experience with tool tables is that they are painful to set up and align. We had to remove the table at least once a week to clean up underneath the table. After a week or so the chips clog the...

Sorry if I am chasing things that might be obvious, but go on the settings page in Mach and check whether the j,K (radius) values are interpreted as relative to the most recent position or whether...

are the i,k or r values set torelative movement or absolute on the settings screen?

Check the LEDs and tell us what's still on.

Anything on the front panel?
Anything on the PCB?
there are two types of fuses in there, some are sacrificial fuses and might have burned through....

that's pretty much how it is done.

the vacuum plate itself is actually is held to the table with the "regular" bolts. there is no vacuum holding the vac plate to the mill table ( I know you...

the new thing about the video was the announcement that they will launch the product in the short term.

... now we're cooking with gas ...

they cleaned up the machine really nicely for that video. 'wish my machine would look like that every once in a while :)

Cutting perimeters is not a problem. we sacrifice some of the nice table surface and go 5 thou deeper than the piece. has not influenced the flatness quality so far.

Flatness of the...

We have the vacuum set.

1. the table works great and is a real help. Holds on to plastic and other soft materials like a charm. We use it to cut structures into PVC. It will not hold on for...

is there a newer version than V7?

Bei Tormach gibt es eine umfangreiche Beschreibung, wie man einen PC auf den (erfolgreichen) Betrieb von Mach 3 umruested. Das Thema laptop steht dort auch, es ist aber nicht das einzige Thema. So...

How long is the cable between mill and PC?

How deep do you go with the first pass?

IMHO it is not the spindle but feed and depth. Looks to me that the 1-flute engraver is vibrating because it is being pushed. I would increase the number of...

depends on the temperature in the shop for us. In the winter morning when the shop is still cold, it takes a little longer. But 15-20 seconds sounds about right. We also use Vactra-2. If it goes...

there is really no point in shipping aluminum across the Atlantic unless you desperately wanth the SAE dimensions.

We have the spring loaded engraver. Depth of engraving is controlled by feedrate, rpm and the spring. The piece works well if you want to engrave on surfaces that are not totally flat, it keeps the...

You probably have to extrude-cut twice and see later on whether the pieces still fit in an assembly.

I would make the piece out of 15mm OD stock (that's probably how they came up with this). If you are lucky you can even buy the stock as tube with the required wall thickness and just have to take...
