The Danfoss VLT 2800 works very well to spin the excellon QD820 and QD 1010 spindles. You just need to get the parameters and wiring right,


To begin with make sure that the switching frequency...

Thanks for pointing that out Mactec54,


What I meant was DC powersupply not drive.


And Larry, yes that deal sounds amazing, but I use Deskcnc so the breakout board dosent really work for me...

Why dont u try contacting Custom drilling, eti , probe industries

in India try

Drill care, SLN, Kannur

Maybe they can help

Hi there,

After 6 successful cnc builds and retrofits, Ive started to get an urge to go beyond the 150 ipm speeds with steppers and am planning to start a new machine with AC servos. The...

Sorry didnt read the second part to your question.

You can drill and route a stack of upto 4, 1.6mm thickness pcs only if ur spindle is very good and powerful and your machine is tightly built. ...

All PCB manufacturers use entry and backup materials when drilling copperclad laminates.

The drill is never supposed to hit the metal bed and thus it is recommended u place a 2-3mm thickness...

Hi There,

Let me be of some help, the 1010s are for drilling any radial load will kill the bearings. Since u picked them up from an auction im sure u got them real cheap but I would expect the...

Hi Samarbaga,

That layout looks like double sided PTH, For 3"X4" I think I can have these made here in India for about 2 US $ each and sent out by mail or something.

Will be glad to help.

...

Guys, I didnt mean to be rude towards Tony when I asked him to search for older posts, I was helping him get answers to his own questions.

Look at this post, are we sharing experiences here or...

Tony611,

Please do some hard work and go through the cnczone site in detail.

Differences between steppers and servos is like the anthem of this site and everything has been explained very well...

Hi everyone,

I needed some guidance with trying something I haven't done before.

I have been asked to help make some punching dies for PCBs. Most punches will be 0.8mm-1.6mm in dia. These will...

Great work, keep the progress on and all the best.

Most PCB drilling spindles would not be running of a belt simply because even if you could keep the runout withing .0001", which is the pre-requisite for drilling holes that small, the very vibration...

Hey Guys (and Gals if there are any over here),

I ve been using my cnc machines to do work since almost 3 years now and am proud of all 5 of them since they all are working. Now, during this...

Its cool if you can see through it cnczoner, I would have done it if I hadnt stopped writing codes 7 years back, but just in case you do write something like that, put up a compiled executable file...

Thanks Bill,

but the deskengrave dosent create toolpaths for serial numbers,

I did however find something similar to what i need at 2linc.com, only thing is that its $350 or something, let me...

Hey guys, thanks for looking,

I need some help finding a software that will let me engrave serial numbers from say 1 to XXXXX. I got my self into this trouble after I engraved some PCBs for a...

Yeah, I forgot to add that, you can do that only with 6 wires so you connect one phase and a center tap as a winding to the bipolar drive, you cant do that on 5 wire unipolar ones. Thanks pminimo for...

adrobbi,

if all you want to see is the motors spinning, you can wire unipolar motors to bipolar drives but you end up compromising on torque. You do this by using only half of the windings of a...

You could always try some carbide pcb drills, the shank would be 1/8 inch and sizes start from 0.3mm

I too have been using the deskcnc controllers for some time now and have had similar trouble with the software when using the estop terminal. In my machines, instead of going into an e-stop mode, the...

Excellent work done BoB, all this while I thought my enclosure designs were good but your work is simply fantastic. Guess there always is lots to learn.

Your problem has to be related to the high voltage, if I were you I would run these motors at something in the range of 36-48V,
try to check the motors resistannce as well using a multimeter if they...

Hi JerryFlyGuy

The Quietdrill spindles I use certainly deserved to be named so, however they are just 1Hp



Dev

You could also run the motors in a bipolar series configuration at 65-70 V but full current of 4.5A a phase without straining the geckos. Might just be good enough, see the motors torque/speed curve...

Hi,

I have been using Kavo and other HF spindles for a while now.

As for Kavo, they are very expensive I would say. A small 150 watt spindle alone can cost upto 1500 euros and another 5-800 for...

a docking station should be your best alternative as of now

Blue PCB looks cool, waiting to see the specs on this beauty

Hi, I use deskcnc and use a relay trigger using the spindle on function in the softwatre. Spindle speed in my case is better kept adjustable with an external 10K pot, gives me easy control.

U...

Deskcnc works only with the deskcnc controller, and I found it to be very easy to configure and use.
Worth every penny spent.


Cheers
