When I converted my KMB1 I found it much easier to ditch the original relays and use SSR type, they can be switched with the low output directly from my PMDX 126 break out board, this made it very...

I have copies of all 3 masters, have sent you a pm

I have copies of the masters on floppy disk, if your machine has a floppy drive, I can send you copies

The new bearings I got for my kmb1x are fafnir 2MM207WIDUL, these are what was fitted by Hurco, the box says C1 super precision. I have not fitted them yet, but as far as I can tell the preload is...

what post processor are you using ? Maybe martin cnc or accurate machine company may be able to advise on what post processor to use, I have converted my KMB1x to Mach3 so never tried to drip feed it...

Thanks Bob, for the explanation, that is helpful, and thanks Dan for taking the time to post the diagram, I have the machine back together again with the new bearings in the head, I realized that the...

Yikes, that means I have a potential flat out speed of 26,600 rpm at the spindle ! I am going to have to rig up a tach to see what I am actually spinning the spindle at

Yes please Dan, that would be great ! I have also read today that a VFD can drive a motor much faster than the motor is rated if it was running on direct mains power, if that is correct I will have...

No it has the vari-drive head, looks the same as the later hawk machine

The speed dial goes up to 4000rpm, so I guess it must be a little faster, I hopefully will be able to get the bearing sizes from a contact I have tomorrow, the parts book I have is for an SM1, but it...

After having another look at the bearing retainer when I got home from work today, I have realized that it will be a simple enough task to turn a new one up on the lathe. still unable to find the...

Ahh, my machine is a kmb-1x so the head is different, there is a bearing that sits inside the brake shoes held in a cast iron carrier, I have managed to break the carrier whilst trying to extract the...

Bob, did your machine have the mechanical hand wheel speed control with two speed gearbox on the head ? I started to get some noise from the head will doing a job today, sounded like a bearing had...

This makes sense to me, I have the timer like you have Bob, the 15min mechanical one, but everytime it fires off the contactor bangs in and out a few times as the micro-switch comes off and on the...

Do not allow anyone to lift it by the straps around the head ! I know someone who did on a KMB-1, and it did not work out well, the machine was damaged beyond economical repair, I bought the servo...

Thanks for the the info Bob, I had looked at cambam, and i have downloaded a few other demos, Bobcad and Visual cad from mecsoft, the visual cad has a free for life cutdown version built into the...

FannBlade, I am all up and going, been off on leave and have worked all week on my Hurco, got the brake, lube pump, flood and mist coolant all up and running, I have even cut a few test runs
If I...

Great !! Another Hurco build, I can`t believe after re-reading Bob`s hurco thread, and looking at the dates on a couple of my own posts that it has its been 18 months since I have had a chance to get...

Sucess ! I have fitted some 1K "pull up" resistors accross A to 5v and B to 5v as per the instructions on running "heds" encoders on the gecko support page (even though these are standard hurco...

Sucess ! I have fitted some 1K "pull up" resistors accross A to 5v and B to 5v as per the instructions on running "heds" encoders on the gecko support page (even though these are standard hurco...

Thanks for the information and the part numbers on the E6 encoders, that is most helpful, I think I will go ahead and order these,

When using an external +5v for the encoder because it draws more than the gecko`s limit of 50mA, what connections should be made at the gecko drive pins enc gnd and enc+5v , ( if any), have tried it...

First of all, you need to have err/rst hooked up to 5v, the drive will do nothing without this, so a link wire from ENC5V to ERR/RST on the drive itself

next , you will need a seperate +5v to the...

you have just answered my question that I have not asked yet, thats impressive !!!!

found the post regards the AMT-103, and noticed that the largest shaft size was 8mm, yes my motors are 1/2"...

I will crank up the standard machine tomorrow and take a look at what is going on with the timer / lube pump, I hear what you are saying regards the operate button oiling, I have never had the need...

I have two identical KMB-1`s one is still in standard form, both have the elctrical timer (120v ) that ticks away all the time the machine is in operate mode, and gives a signal to the lube pump via...

Steve Stallings at PMDX gave me a great tip on the limits, I had hooked all mine up to seperate inputs on the break out board, but as youy say, mach does not know which limit it has hit, but it does...

Thats not Bob`s control consul, its mine , I am doing a similar conversion to Bob, on the same machine, consul is far from finished, just put up pics to show that PC did fit inside the arm consul

well, I managed to get the whole PC into the consul on the arm, now have good access to the DVD drive, and two USB sockets out the side, will have to put an extra cooling fan on the back

Have...

I test ran my encoder monitoring the amps, it has other connections not used with the gecko`s, A- B- INDEX and INDEX -, so with all these not used, it must draw less, It draws 47mA at rest,
and...
