    Re: Yaskawa 626VM3 Repair?

    Not sure if I can help with any of that. My Tree is super simple in it's set up. It has a 0-10v analog freq control, zero speed, freq agree and one other thing, plus a fwd and reverse that go to a...

    Re: Yaskawa 626VM3 Repair?

    I like the TECO drives. They have a good bang for the buck, and I haven't had any issues with mine at all. Only problems are that the drive I settled on was a little bit undersized like I...

    Re: Yaskawa 626VM3 Repair?

    I had a yaskawa drive, I think it was anyway, on my Tree 325J. It died and I wasn't exactly thrilled about putting a used one back in that was in who knows what kind of shape for some serious $$$. ...

    To buy used FSL h-series or not?

    Got the opportunity to grab a 2011 vintage FSL 40w CO2 hobby series engraver for $600. It has low hours but has sat in storage for almost all of it's life. Is it worth it to get this thing? I know...

    Re: Converting a 325 from 3.5k to 6k RPM

    I tap at 500 rpm in just about everything. Biggest I have done is 1/2-28. But mostly I do 10-32 and M5 and M6. So bigger/courser than 1/2-28 I am not sure of. 1/4-20 it bangs out just fine and...
  6. Re: Speeding up spindle from 3500rpm to 6000rpm J325

    Pulley, belt, and then you have to run a jumper wire in the cabinet to get the control to read the 6k input on your programs. But its all relatively simple to do.

    Re: Converting a 325 from 3.5k to 6k RPM

    I love it. The belt speed is a bit high for my taste and it makes some noise because of it, but overall its great. Still has plenty of torque for what I do and I have to run it freaking hard to get...

    Re: Old servos and adjustments?

    I got the thing spinning at around 300-ish rpm or so, and it was pulling 3-5V off of the tach. So at least that seems to be working to some degree. I tried swapping the polarity, no dice. Just...

    Re: Old servos and adjustments?

    OK, So I have tried it many different ways, and can't seem to get it to work. I lack the mean to test the encoder in house. It's an HEDS-9140 #A00. I have tested the tach and it outputs some...

    Re: Old servos and adjustments?

    Thats pretty much it. You make sure the table is aligned to a couple arrows and that the Z is all the way up but not hitting the limit switch. Then you reference each axis so that it picks up the...

    Re: Old servos and adjustments?

    Zero is not an issue with this machine. When it shuts down you lose the zero every time. It was the way it was designed. No home switches, just limit switches. So it's stupid simple. Kind of...

    I took the disc off of the shaft as I had to in order to get to the offending bearing. I am hoping that I didn't mess this up. I found the data sheet for the encoder and it looks like they still...

    Old servos and adjustments?

    So I have a Tree 325J. It has been a solid machine but a bearing in the Z axis servo died a very miserable death. Like an idiot I jumped right in before googling stuff and tore the thing apart...

    Re: Renshaw prob?

    I think the Dynapath control might allow it as I think I remember reading about probing in the programming manual. But not sure how to do it. In the past the techs at Dynapath have been way awesome...

    Re: Tree journeyman 325

    I got the pulley from American Metric. It was a 10 groove, but I only needed an 8 groove or somehting like that. It was a year ago so my memory is a bit off. Also, it used BSW threaded screws...
  17. Re: Tree 425 Master journeymen with delta 20 needing a programing manual

    I do not. I have a 325J so the wiring diagrams are different. You can email ZPS USA and see if they have a diagram for you, but you might have to pay for a copy. Someone on here might have one,...

    Converting a 325 from 3.5k to 6k RPM

    I just got done doing up my mill to go faster and thought I'd just drop a thread to help others. My mill is a 325J. It has the 3500RPM spindle, with the Yaskawa spindle motor and formerly yaskawa...
  19. Re: Tree 425 Master journeymen with delta 20 needing a programing manual

    Here is the EIA/G-code section. It would take me a good long while to scan in the rest though.
  20. Re: Speeding up spindle from 3500rpm to 6000rpm J325

    never mind. Got the pulley situated and my machine is now running at 6k. Going to have a go at some parts with it tonight to see what it can do. Hooray for more SFM!
  21. Re: Speeding up spindle from 3500rpm to 6000rpm J325

    Did you ever get the speed thing sorted out? also what diameter were/are your pulleys? I just did my calculations again and I think I am off a bit and am trying to sort it all out. I have been...

    Not to dig this back up, but I need to switch my 3500 spindle to 6k. I found the pulley that which I need, but from what I have seen, something needs to be switch/tweaked/jumpered/something to get...

    Re: spindle override switch problems j325

    What VFD and such are in your machine? I have a 325J from around 1992 with the Delta 20 with the Yakisawa VFD and motor. Was machining away today, ran a program about 20 times. Went ate some food,...
  28. Re: Speeding up spindle from 3500rpm to 6000rpm J325

    I don't think Dynapath would be able to do that. I would talk to ZPS or whomever is now doing all of the Tree parts. They would probably have the info you seek. Might even have it for cheap. I...
  29. Re: Speeding up spindle from 3500rpm to 6000rpm J325

    That might be cool. I have a buddy that could help me make the sheave as he is going to be making a couple for an RF45 conversion so he can get 5-6k on the spindle. Might just have him kick one out...
