Thanks for your question Lappa. I have amended the original post with the addition of the following information.
two are Eastern Air Devices LA34CKK-P500E 5A/10A 1.8 degree
one is Electrocraft...

Hopefully I am allowed to post this here....
I have posted in the Market Place under Metalwork-Machinery section, three USED NEMA 34 stepper motors, these are large and powerful LA34CKK motors,...

I have three used NEMA 34 stepper motors for sale that I was going to use in a CNC project but never got used. The part number is LA34CKK. Two are Eastern Air Devices LA34CKK-P500E 5A/10A 1.8 degree...

I have some experience with the Big Easy Driver as I used them in a different type of project to drive Nema 17 size motors. Whilst they do the job, adjusting the current to suit the motor is fiddly....

Very nicely done and a good idea! Might try something similar. Is it a battery powered clock movement?
cheers

Hi Rob, is the cutter already defined in the tool data base? If not there is a process you have to do to design the shape or profile of the cutter and then add that to the data base as a round over...

Hi, regarding "water cooled spindles" I would like to comment that I use car radiator coolant from Supercheap Auto or similar, and not water. A fellow I know uses tap water and complains that algie...

I might be able to help if you are local to Albany Creek north Bris. I sent a private message to you.

I just bought this one the other day from McJing Tools On line .. should be here soon in the post . I cut a lot of thin ply so will be interesting to see how it goes.

They are in Yagoona NSW

Hi Broomy, Good to hear you are "still kicking". It has been a while since we last met and I have often thought of you but I have been very slack in not keeping in touch. I could use the excuse that...

Hi Eskimo, I too have been following this impressive build with interest and as a result I have been doing a lot of reading and research into the Napoleon cannon and the American Civil War.

Those...

Goodness !! did I cause this flaming?
Half truths and misinformation.???.. As I said in my post, I have the same motor so was able to give comparative readings directly from my motor, doesn't that...

Hi Boothie, I have the same motor and using a digtal multi meter it reads over 10million ohms or virtually an open circuit between the metal case and the wiring. A special tester called a MeggerOhm...

Hi Tony,
Not sure if this applies to your setup, but I had a problem with stalling and missed steps and no amount of motor tuning would seem to work. I ran the driver test program and the displayed...

I doubt any one knows the answer to your question as it was posted two days ago and no replies. I don't know either but I have the same spindle and it has been running 24000RPM for hours at a time...

I wonder if at this stage you should try temporarily disconnecting from the BOB and use an external potentiometer to adjust the spindle speed and that will prove the vfd is set up properly for...

Nah, never got that far. Silly thing is, if it was for a kids sporting club or similar non commercial use, I would have done it free if the timber was supplied. As a new machine user I just enjoy...

That is one nice machine you have there, fast rapids too.
Do you have the VFD manual? a copy can be found in the CNCZone Forum..

Hi Ray, I made contact with a Cinese spindle manufacturer via the Made In China web site. A quote came back of $525 for the spindle and $195 for the vfd plus $98 delivery. I told him I got a spindle...

I made contact a few times and he agreed to send me the file .. but never heard from him since..

Hi Russel, I pulled my 1.5kw water cooled spindle apart last night, and mine seems different to yours as far as the bearings go. I have a wavy washer preload spring under the top bearing and two...

Hi Ray, yeah it was a long night last night..thanks for the support.. still it is all a learning experience .. keeps the brain working hopefully... You must be a glutton for punishment and if you are...

Dan you did a good thing so relax. You pretty much described the moral dilema I face most days when I get requests for help from our dealers "engineers" in Asia and just by the question I know they...

No offence taken and I totally agree with you, but just to clear the air, I have been repairing electronics and controls systems for over 35 years, including motors and I hold an electrical license...

Kinda had the spindle running.. then smealt hot motor.. looks like it has killed the motor. Put the good Lenze vfd on to it and errors.. the English manual from the American manufacturer says short...

I have the vfd connected to the spindle now. At turn on no erorr ELus, just flashing T0000, pres run, the motor spins brieflly then error EOCA, which at a guess is error over current. I have just...

Hi Ray, Thanks for your time and pics. Well I got some time today to have a poke about..turned it on and the same error ELus as usuall.. started to measure voltages.. mains 239V, across those big...

Hi Ray, I got the bridge out and it tests ok with my multimeter. I got a pinout for the MDS35-16 bridge off the net to make sense of the 5 terminals. Nothing looks burnt or stressed on the boards. I...

Hi, Ray and I have been sending PM's regarding repairing the VFD.
So I have pulled apart the 1.5Kw VFD and the only thing I find suspicious is the arrangement of the two large capacitors that can...

Well i have given up on the Huanyang vfd, I never heard back from love Happy so the 2 year warranty doesn't mean much. I bought a Lenze SMV Vector Inverter from FCR Motion Technology at Brendale QLD,...

Hi Ben, I know you found what you were looking for but not sure if you know of Admax scrap metal near you at Virginia. I was there last Saturday and there was a lot of stainless steel and aluminium...

I hope it is ok to post in this thread about my VFD problem.
It is a 1.5Kw water cooled spindle and VFD unit I bought as a set from Ebay. I have had it running for several months now via Mach3 but...

PM sent to you
cheers

Thanks Bob.. I have learned a lot from this forum and want to give back in some way...yes I am offering to the forum members to make the castings of the mounts as long as the member supplies the...

I have been lurking here a long time and have learned so much from the members of this forum.. thank you.
I have been slowly building .. nearly a year.. my own designed machine with a cutting area...

I have a 24 volt 1.6Amp power supply I salvaged from a printer. You can have it if it you want it. It is about the size of a brick.
I live In Eatons Hill about 15 minutes drive from Jaycar at...

Can I ask about the coolant used in these "water cooled" spindles? I read somewhere on this forum I think that rust had caused the demise of a water cooled spindle. If tap water was used I could...

Hey thanks Peter.. I have gone in and changed a few settings .. It used to work before so I assumed it was the server upgrade and not my settings...thanks again.
cheers

Hi Team.. great job so far.
I have replied to a PM today and also sent a new message to that member but I am not sure the message is going out as when I try to open "Sent" in messaging, it shows...

Just wish to comment based on my experience. I have a similar rubber keyboard that I used for my computer I have built into my 4wd for navigation. I liked the idea of being able to roll it up to tuck...

Hi Bob, yeah I tried WinRar to zip but I still couldn't upload .. maybe due to being a .EXE type file which could be interpreted as a virus.. dunno. Or maybe the file exceeded the size limit. Anyhow,...

I have two drivers of which either seem to work but the server won't let me upload them to this forum so I can email if needed. Here is the manual.

Peter

I got two of those touch screens and the image is good but I couldn't get the touch screen to work on either of them. I tried different drivers, rebooted the pc, suspected I had a faulty com 1 port,...

Michael, your comments reflect my reasoning for buying local, well dealing local anyhow. No doubt they are buying from possibly the same guy in China that others here have bought from direct, but my...

For what it's worth: I bought my supported linear rails and bearings from them. Good service and communication, I would buy from them again.
Peter

Hi Michael, yes that LM3940 should be fine but be aware, and I am sure you are, that the 5mW value in the 5mW laser refers to the power or wattage of the light .. not the current used by the laser....

Sorry guys i didn't mean to cause difficulties or over complicate the issue with my response. I have been involved in electronics a long time and probably take too much for granted. Probably the...

Can i chime in here? That circuit is used to set the current for a LED usually around 20 milliamp, determined by the input voltage.
Laser diodes are different from LED's (although they are similar,...
