Hi,
in Fusion you can draw using splines and then run it through CAM to get Gcode. Not sure how the conversion is done or when, but a spline drawn in a part is faithfully machined.

Hi,
I would agree that 30mm rails/cars is outsize relative to the anticipated load. Having said that there is no penalty with using larger more rigid parts other than cost.

I do think however...

Hi, w
where abouts in NZ are you?

I'm in Christchurch.

Hi,
the MB3 has a sophisticated PWM output that derives its own independent power supply from the internal supply of the MB3. It has linearizing and setting circuits.
You've paid for it why not...

Hi,
I thought you said you had an MB3....then why are you bothering with the C6??? The MB3 has a 0-10VDC analogue output, and is way more sophisticated than the C6.

Hi,
I reckon you are going up the garden path.

I suspect the servos are dithering.

Lets say the commanded position is 123456 but the actual position (encoder) is 123457. The servo will try...

Hi,
last week I was doing a job for a customer where I had to make 14 parts out of acetal. The total machine time was about six hours.

My coolant tank is only 10l, and yet through the course of...

Hi,
flood cooling is just so much the 'night and day' difference that I sought. I use to use air-blast and oil spray, and it worked OK.

With sticky grades of aluminum (3000 series and some of...

Hi,
I agree and think that NFS remove good and stable builds of Mach4 way WAY too early. There are thousands of users running 4809 and will be for some years yet. It does everything that is required...

Hi,
The table I used was actually given to me as it was going to be scrapped. It was the base of a 'pick and place' machine. It is 1300mm x 1100mm and about 600mm high. It has a half inch slab of...

Hi,
if you are using coolant you need a much bigger table top. You need sides to surround the whole machine otherwise coolant will go EVERYWHERE. I had flood coolant on my first
mini-mill but it...

Hi,
Greg has been working on the plugin in Andy's absence and I believe 309 is the best for 5036.

Personally I would use 4809 and its matching ESS plugin version...if you can still get 4809. It...

Hi,
just as a thought experiment imagine the machine sitting on a concrete floor, not bolted to it, but just sitting on it. Would the machine work? Would it vibrate when cutting?

Now imagine...

Hi,
if you have a recent build of Mach4 then it will certainly be of the 5000 series, probably 5036. In which case you will absolutely need a new ESS plugin, I think 309 is the current
and most bug...

Hi,
it seems to me that you are making a large project for yourself for little or no benefit.

It has already been established that the table on which you sit the machine will have little to no...

Hi,
it might, but then again it might not. What you are trying to do is stop the noise from affecting your machine.......but the noise has already got in there.
What you should focus on is...

Hi,
you should separate the signal cables as far as possible form any highly electrically noisy cable like a spindle cable. 150mm of separation will provide a marked improvement.



You cannot...

Hi,

how many of these things do you expect to make? Be realistic here....all very well to make a machine production ready but have any of your designs been repeated?

I would guess a new Jager...

Hi,
what build Mach4 had you been running and what build of Mach4 are you updated to?. What motion controller are you using?

Mach4 came out a while back with the first of the 5000 series builds...

Hi,
to my knowledge this spindle (Jager 5.5kW) was not available at the time I bought mine. Had it been available I might have bought it rather than the new Dake (Chinese) 3.5kW spindle I did buy.
...

Hi,
that secondhand Jager spindle is very close to the current model:

If you have to ask how much....then you can't afford one!

Hi,



BS. The filling material must adhere to the inside of the section, and then any flexure in the tube is transmitted to the filler material which in turn dissapates energy. This is the...

Hi,
I know you're not big on second hand but this looks very good indeed:

Hi,



Vibration damping???....but the table on which the mill sits is not in the load path. The load path is from the tool, to the spindle, to the Z axis, through the column
to the base,...

Hi,
there are plenty of ISO 20 spindles, mainly Chinese made. Jianken is a known brand and have been in the market for twenty years.

ISO 20 refers to the diameter of the taper at the spindle...

Hi,
if I understand correctly is the mx3660 just three stepper drivers in one unit? I presume three of the boards are identical, one for each stepper, and the fourth board
is an IO board?

If...

Hi,
what are the drivers? Are they for steppers or servos or what?

Hi,
have FINALLY got my new spindle through customs, taken three months. Started with NZ Customs seizing the spindle, ie total loss, no compensation, no nothing, as a result of a false declaration...

Hi peteeng,
remember your mothers advice....'look before you leap'.

Hi,
sorry I have miscalculated...I posted:


When it should be:

steps/inch is (25400 / 6.25)=4064 steps/inch. So divide rather than multiply.
