Hi,
you can cause or force Fusion to post Gcode to your liking. For instance by putting a G55 at the top of your code.

This is done with the Manual NC option of the Setup tab (pictured).

By...

Hi,
a second consideration with rigid tapping is thread engagement. This applies to both conventional rigid tapping and Gcode synchronous rigid tapping, but any failure is catastrophically worse...

Hi,



Hand scraping is a useful technique to go from 0.01mm to 0.001mm, but any suggestion that you can remove as much as 0.1mm is a joke....you'll be there forever. Milling or grinding to...

Hi,
the real question here is do you need to cut steel or not? Steel is that damned tough that a machine for aluminum and brass is one thing but a steel capable machine is another.

If you want to...

Hi,
I bought a pair of wire strippers while I was at University in 1980. I was working with the electricians at one of the countries largest freezing works over the summer break.

Such tools were...

Hi,
one of those failure modes is if the tap twists even slightly in the collet.

I have an ER25 collet chuck on my high torque/low speed spindle (pictured above) that I use for rigid tapping. You...

Hi,
ah, yes, that would make sense if they are to be bonded into the UPHC.

Hi,



Why? I've used black (oxide) bolts, screws, nuts etc for my entire life, never had an issue???

Craig

Hi,
to be honest I agree with pippin.

I have a servo driven spindle, and being a servo it is position capable....so I 'tricked it' into doing rigid tapping. If it is used as a C axis, ie an angle...

Hi,



Ethercat does not do that, rigid tapping is more about the software solution. For example Mach4 does not (natively) support rigid tapping, with or without Ethercat. LinuxCNC is a realtime...

Hi,
I have no doubt about samcos veracity, I too always read and consider his posts very carefully, but in this case he has not built or operated a hobby level Ethercat machine.

Craig

Hi,
samco has stated quite plainly that he has not built an Ethercat machine.
Shine is 'working' on a NC/Ethercat design......and I take that to mean he has not yet built a working Ethercat...

Hi,
Its not so much that PG/NG PP and NP have voltage on them but rather they will have a voltage tolerance. If they are differential, as I suspect, then they will be 5V tolerant, and therfore if...

Hi shine,


I have a five axis machine with Mach4/ESS and Delta B2 servos. I homed the fourth and fifth axis three weeks ago, and never had to do it since. I never bother turning my machine off...

Hi Callum,
I looked very closely at a Mach4 Ethercat solution 3.5 years ago when I was building my mill. At that time the Kingstar package (PC+Kingstar Ethercat license+RTX64 runtime...

Hi,
the connection from my breakout board to each servo drive is a nine core flex cable (6mm diameter) less than 600mm long....Ethercat is saving me very little. For a modest three four or five...

Hi,
if a Gcode program is running and you hit <FeedHold> the machine will stop, and depending on how you set up the defaults the spindle will stop. If you hit <CylcleStart> the machine will resume...

Hi pipppin,
you are 100% correct. I am very familiar with the B2 manual which definitely does not have general purpose inputs. The A2 and the A3 have four transition sensitive Event pins, and also...

Hi pippin,
I certainly will read the manual.

You still have not answered the question.......what is it that Ethercat brings to the party that a regular motion board does not?

Craig

Hi,



As has been explained, this button is an EMERGENCY STOP.......it is not in anyway concerned with what might happen if you restart the machine incorrectly.



There is a procedure...

Hi,
looking at the pinout I would guess the pulse Ste/Dir inputs are differential. You need to confirm voltage level. Single ended digital inputs tend to be 12V or 24V but differential inputs tend...

Hi,
the only thing I am aware that Ethercat can do that my Ethernet Smooth Stepper (ESS) cannot; is the number of motors.

As you know Mach4 can have up to 12 motors, 6 coordinated and another 6...

Hi arturod,



Why...what does it do that makes it better?

Craig

Hi,
fine your limits and home switch, if you need one, go direct to the drive....but what about non-servo specific IO, say a probe input or inputs, or various pump outputs?



Those inputs...

Hi pippin,
yes Ehtercat for free.......but what do you get with Ethercat? You still have to pay a premium for Ethercat servos but the what about non-servo IO? For that you need Ethercat IO...

Hi,
Mach4 can be run as Ethercat.

There are two solutions:
1) Mach4 communicates with a motion control board that has Ethercat realtime comms, Vital Systems offer a board of this description....

Hi,
if you are using Mach4 then you need a Mach4 compatible motion controller, of which there a a half dozen manufacturers with probably 20 models all up. As I stated earlier I use an Ethernet...

Hi,
just as a by-the-way; you can now see why I recommend looking very closely at the availability of ALL the components of a servo system. I have personal experience of buying what I thought was a...

Hi,
the real question is what CNC software do you want?

I use Mach4 and an Ethernet SmoothStepper and have done for nine years. I would avoid Mach3, all development ceased on it nine years ago,...

Hi,
some years ago I bought a remanufactured 3kW Vickers AC servo from cicra 95. Its in perfect condition. Once I got it I realised that I could not find an affordable drive for it. It is equipped...
