There was continuity between the 0 posts, but I hooked it up with the link disconnected.
Turns out I have 240v instead of 230v.
I measured 103v between 180 and 0 when connecting to 420 and 0....

For comparison the E6 are optical, and can have single ended or differential output. They also have 10000cpr output. Max bore is 25mm
The amt102 are capacitive, have a max cpr of 2048 and max bore...

Incase anyone ever wonders the same, these encoders have differential output.
Went with the AMT102 though, because these were just too expensive with the programming cable and all.

Thanks for the reply!

I will disconnect the link and measure what I get :)

So this retrofit got postponed long enough.

How do I correctly wire the autotransformer?

I noticed that the two 0 points are connected together, is it supposed to be like that?

I have...

Hello,

I need to swap the encoders on my old sem servos.
Will be using DG4S drivers and they require differential signal.

Have looked at AMT102/AMT103 encoders but they send single ended...

Genuine Leadshine? Probably just imported chinese stuff.

So you think they are working good, but have no evidence to show for it.. Allright I will take it as a subjective view..

Hi,
Does anyone have any experience with theese https://www.aliexpress.com/item/EU-Ship-fee-Taxis-to-EU-Nema34-Closed-loop-Servo-motor-12N-m-6A-2HSS86H/32736249259.html ?
Looks like a nice motor....

You should use the thickest steel you can get, and also fill atleast part of the tube. The tubes are just like bells, so they will resonnate a lot.

What is that big thing? :cool:

The surface you used looks like it's been ground. But what you did was make a negative of the surface on the block. It's enitrely possible that the surface of the...

What did you use?
Show me :)

That is a small tap but still doable. What you're trying to do is rotating the tap clockwise to screw it out of the threads. Once you get it going this is not really that difficult..
Maybe try a...

I have broken many taps.. Last time was an m16 tap in aisi 316. Just get a centerpunch or some other hard steel item which can enable you to apply a force to the tap to screw it out. Sort of knocking...

Nope. When I bought the machine the tnc control was already sold off..

That was an informative read. Thanks for link!


I will still use my existing transformer. Should get 154VDC. It's 9V above the baseplate reading on my motors... Should be okay :banana:

The picture shown is a 1 phase transformer. Yeah I have noticed its almost the same for other Bridgeports too.
It's a very versatile transformer. You can connect it to 210,220,230, 240, 380, 400,...

I am doing a retrofit on my Bridgeport. So will be selling the Bosch Z15-1A-240 motor drives.
Drives are in fully working condition.
Can also sell the chokes and encoders on motors if anyone needs...

Thanks. Any ideas on why the DG4S servo driver require using 2000uF per motor amp?
I think I will also use 200vdc caps due to the braking circuit.

Hei,
Jeg har en slik kompressor som tidligere var en vakuum suger, altså hele greia fungerte omvendt. Men den jeg har er en single stage LE80. Som jeg bygget om ved å lage nye rørdeler ny manifold....

Hei,
Den oldham coupleren skal være ganske bra. Du får finne en pdf med spec over koblingen du ønsker å se hvor mye den kan ha av misalignment..
Aluminium er ikke egnet til slike spiral koblinger...

Excellent, thanks for input!

Al, what are the specs on the capacitors on your dc psu for 3 of those motors?

Been thinking on how to correctly size the caps, wondering about the farads and the...

Hi all!
I have a Bridgeport Series II Interact 2 milling machine that I wish to retrofit to a new servo control but still using the old dc motors.
But I need a dc psu for the motors, and was...

Hi,

How have you wired your ESD to your CNC lathes and mills?
I have a cnc mill, and I'm wondering what is the best way to do this in a safe way.
Using smoothstepper, cnc4pc c32 bb, gecko 201,...

Hi,
I'm in the progress of wiring up a cnc project, and after wiring my drives to the dc power supply I started to check for shorts and measure continuity.
With the chassis I'm using there is a...

Looking good!
Is it good to have the VFD in the same enclosure as the PC or cnc electronics?
I'm no expert here, but I thought the vfd would produce noise which disturbs the cnc electronics?

Hei,
Som jeg skrev tidligere så klarer g540 maks 3,5a per motor.. Den siste der vil den klare.

Vil absolutt anbefale at du roer deg litt ned nå og leser noen titalls timer på ting rundt cnc.....

Hei,

G540 tåler maks 50vdc. Du bør holde deg litt under dette med ca 48V..

I understand.
How would you preheat and stress relief the metal?
I've read that structural steel (s355) should be preheated to 200c, and stress relief at 600-650c. They say to heat the metal 1 hr...

Zach,
Nice pictures. Do you have any more videos of it in action with flood cooling? :)

Why would you want to stress relieve the steel?
Can the steel move after a certain amount of time, say a...

Try milling out a circle.
Example: Try milling a 50mm circle, check if the circle really is round by measuring across it in both directions x,y. Is it 50,00mm or is it perhaps 50,1? 49,9?

Mill a...
