Hi,



Not really. Mach4 does have quite a few videos so that part is reasonably well covered. Its the practical wiring of the controller to the servos that will give you the most...

Hi,
sounds like the battery that maintains the real CMOS clock has gone flat. Its common with machines of this age. Unfortunately its not as simple as just replacing the
battery......critical data...

Hi,
I have been experimenting with different arrangements.

The coil needs to be about 40mm in diameter, big enough to easily fit over the tool holder nose, but small enough that there be good...

Hi,



You are already there.....get the kids to show you.

There is some stuff that many find tricky, like interfacing the Step/Dir outputs of the breakout board to the servo drive. The servo...

Hi,
I don't use plasma so I cant be 100%.

Firstly I'd recommend Mach4 over Mach3 any day. Secondly Warp9 sell a 'WarpRunner' board which is a combination breakout board and high dynamic THC...

Hi,
well as far as I can tell the drivers ARE Step/Dir type and thus any Step/Dir type controller could be used, which includes Mach3/Mach4 and an Ethernet Smoothstepper or newer Flashcut...

Hi,



That does not sound right to me.

I use Delta servos, which I assume are similar to your Panasonic servos, ie they are Step/Dir. In fact as far as a controller goes they might as well be...

Hi,
sorry, the supplier is Andrews but the manufacturer is 'Command'.

Craig

Hi pippin,
yes that's what it looks like....have you actually tried it? Real world experience is what I want.

For instance the current from the power supply was X when I put a 1/2 inch bar in...

Hi,



Poor bugger!

Anyway, good that you have it sorted. Those KBIC controllers are a 'phase controlled bridge' and to be honest are not great. They were considered good back in the...

Hi,
I have yet to look at the video but it does not say how much induction power is required. Looking at the size of the coil I would guess around 1kW.

The HSK 32 tool holders have a threaded...

Hi,
I have recently bought a new spindle which has an HSK32 tool interface. I would like to move to shrink fit tooling, but cannot afford a machine to do so.

Electronics is my thing, so I could...

Hi,
that technique of sensing a surface is not uncommon. It relies on the motor driving until it is stalled, ie up against a surface and then the motor current will go up dramatically.
The...

Hi,
second impression....the tool change is silky smooth.

The Vietnamese supplier threw in a 2 position 5 way pneumatic solenoid so I have set it up and it works perfectly.

Could very easily...

Hi,
I have often dreamed about making a small CNC mill suitable for hobbyists. Indeed my own mill is my own take on an 1100/1500 style and size mill.

There are certain things which I regard as...

Hi,



Sad fact of life. You're not the only person to have come to the conclusion that you need blocks (poor choice for rigidity) OR a gutter milled into the axis bed.

I my case I had the...

Hi,
in my machine (pictured above) I used new (old stock) THK 20mm rails and cars, because that is what I could get from DY-Global at the time. I would have preferred 25mm, but I got what I could....

Hi,
that ballscrew is 5mm pitch and therefore very little torque is required to offset the weight of the Z axis/spindle.

For a 5mm pitch screw the mechanical advantage is 125kg (weight or 1250N)...

Hi,
got my new spindle today....after a long battle with NZ Customs (my fault). Really nice.....and worth the wait.

First impression is that the HSK32 toolholders are small, you can fit one in...

Hi,
yes, I think the Hass mini-mill is the next step up from hobby level machines....but then where does that put the new Tormach?

Given that's its epoxy granite it must have linear rails/cars...

Hi,



Yep....thats sort of what I mean, lowest cost with 'pretentions' at least to industrial grade. They have been around a long time and are useful for comparison to manufacturers trying
to...

Hi,
the Hass mini-mill has been the standard by which others have been compared, and it must be said the Hass mini-mill is a damn good machine for the money.
This new Tormach is serious and direct...

Hi,
aside from cost, the big penalty about oversize ballscrews is rotary momentum.

I bought some second hand 32mm diameter, 700mm long BNFN double nut C5 THK ballscrews for my project, without...

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.

Craig

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.

Craig

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.

Craig

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...
