Hi Mactec54,

Thanks for the reply! No, it is not a totally original idea, there are quite a few home-brew schematics out there and some commercial options with similar functionality. That said I...

Hi All!
We have a new product up on Kickstarter and thought you may be interested in checking it out: Stepperature: Open Source Quadrature Hand Wheel by ProtoPlant INC. ? Kickstarter
It is also up...

Hi All!

I wanted to let you know about our new line of regulated switching power supplies for servo and stepper motor applications. I have been using Gecko Drives and similar for years for bigger...

Hi,

I have used a home-made tool setter on my 1994 VF3, it was fairly easy really. It needs to break the "skip" signal circuit, I have attached a picture of where it is on the board. There are...

Hi All, thanks so much for all of your input, sorry for the delay. I finished the job and ended up making a small C-shaped jig on the mill that fit nicely over the flange with the hole pattern in...

Also a good idea, although it might require a hole in the wall :-) Ahh for a bigger shop.... Although I might be able to get it done this way one end at a time.

Thanks for your post

Good idea, I think I can implement something like that. There are 4 patterns of 4 holes on both sides of the beam, and they are too far apart to leapfrog. But I can make a fixture that has the hole...

Hi All,

We have a job for some long (122in) aluminum I-beams with holes in them, about 35 holes in each. The tolerance is +/- .030, and our biggest machine is a VF-3, 40X20. Any good suggestions...

Hi There,

I have a 94' VF 3 and just installed a new rigid tap encoder (was missing when I bought it) so have some experience with it now. First, I would go to the diagnostics screen where you...

So I called Haas and they do not have a servo tuning procedure. I have been studying the manual and in the parameter description section parameter 113 "X acc/dec t const" there is a description of...

I really love this thread, beautiful work! As far as loading a program I just bought a 1994 vf3 and it was a bit tricky to get it to talk to the computer. I ended up using a USB to serial (rs232)...

Ok so I found that the wiring for the rigid tap encoder going from the processor stack up to the flex conduit up to the head. Also haas says the machine has rigid tap and it is on in the control but...

Well, I suppose that will have to do! I am sure I will figure out where things can be pushed. Still think I have some troubleshooting to do on this, it is not consistent with how it is cutting on...

Hi cartel, how is your mold cutting going? I have a 1994 vf3 and want to cut at 150-200 ipm as well and was hoping you had some feedback on how your machine is running. Mine is having some issues in...

Thanks txcncman, I looked into the exact stop setting some and it seems to just apply to canned cycles, but I might give it a try anyway. Good tip, thanks.

Hi underthetire, thanks for the post. I was hoping to run accurate tool path at at least 200ipm with this machine, is that in your experience not possible? Would that really be considered high speed...

Hi, I have measured it with an indicator in the spindle in all three axes, seems less than .0005 but it is hard to say how it is under load. Is there a good way to test that? Also, it holds...

Hi all,

I ran a few dozen 6061 parts on a new to me 1994 vf3 last week and I was having trouble with the x or y axes over traveling on higher feed rates. I had a trapezoid shaped pocket with...

Hi edge540. It is a Belkin converter, not sure of the model exactly, I could check on Monday. Also I have not tried DNC, not sure how to do it yet but with 70kb available memory I will probably need...

Hi all! A few weeks back I posted about buying a new to me vmc, thanks for all your input, I went with a 1994 VF 3 with an HRT 210.

I made a nice pile of parts this week and really got to know...

They just put the commet up for sale on craigslist, ultra cheap, $5000. Not sure what is wrong with it if anything, just thought it was interesting. Wish it was a little bigger! Half tempted to...

That is awesome, well done. I had most of this stuff in a garage of a place I rented in Montana while I was going to school. I was nuts, going out there when it was 5 degrees and working on those...

Good idea, I think I am just going to make up most of it, I am hoping the local haas dealer can get me drawings.

Dustin

Thanks for the tips on moving. I went ahead and bought it so I have the manuals now and there is good info in there on how to set it up for trucking it without a pallet/crate. There are holes under...

Thanks for the input, I was seriously thinking about it but I just don't have the space or the resources to up-size. I am in a 1200sf unit with a 200sf office, and have 2 lathes, one knee mill,...

Hi all, looks like this might be the machine I go with, 94 VF3 for $18K. any advise on getting it ready to move? Thanks!

Also thanks for the tip on calling Yamazen, they can get parts for them from Japan, pre-pay and wait, non refundable, non cancel-able, put "probably" possible.

Thank you for your thoughts, I appreciate you taking the time to think about it and reply. It is very helpful to know something besides what the machinery dealer tells you :-)

Hi All! I am looking to buy a used machining center in the next few weeks and am driving myself a bit nuts with all of the options. I am a mechanical engineer who does design work and some...
