New Build - Tree VMC 1000

Hello everyone,

I finally got the Tree VMC in the shop (sort of), its on the floor and under the roof at least. The machine is A LOT bigger than I expected to I am going to have to rethink where I was gonna put it.

This machine has 40"X, 23.6"Y and 24"Z travels and a 42"x24" table. The spindle is 20HP by 8000RPM and I think it has coolant through spind as at first glance there is what I think is a coolant hose piped into the spindle.

The machine is working and fires up, it has a Dynapath Delta 20 control, MSI Servo drives (and servos?) a Yasakawa Spindle motor and what I think is a Yasakawa Spindle drive (no marking I can see yet.)

I haven't recieved the documentation yet, but I should have it this evening so I should have better information after that.

So far I am happy with the machine, upon first inspection it looks like it was well taken care of. One of the enclosure panels was dinged during shipping, but its just cosmetic and I can fix it here on the press.

Some pictures for your viewing pleasures:

Can't seem to insert more than one image per comment...

Again...

I'm debatting what to do as far as the electronics. Right off the bat, the Dynapath Delta 20 is going right out the window, but I am not really sure if I want to replace the rest of the electronics. I guess it'll depend on how well I can make them play with linux cnc and Mesa. I'll have to wait until I have the manuals for that. Any ideas?

The control cabinet looks alot like my journeyman 325 that works just fine on the dynapath

but it lacks memory, I can only run 1600 lines of g-code so I will watch this retro to see how things go

and just maybe i will retrofit mine as well

This thing has a Chain driven 40 ATC with a swing arm. It looks like it uses a regular 3 phase induction motor with an incorporated brake. The chain mechanism has two position sensors as far as I can tell, probably one for index and one for steps . I haven't thought about how to interface to it, but I was thinking it might have a separate PLC or controller that drives it. If it didn't, I was thinking I have some small PLC's laying around that I thought I might be able to program and then just send the tool selection signal from linuxcnc... or maybe set something up directly with classic ladder.

I found a Siemens manual for a drive with the same model number and it was a velocity drive, tonight when I get the manuals I'll dive through them and see. The spindle is a 2 speed unit and I'd guess that one is indeed a velocity+encoder setup, we'll see. So can I assume correctly that a velocity setup is pretty straight forward with linuxcnc? I ask because my experience with motion control in general is with pulse+dir setups.

John,

The tool changer might be fun depending on how it works you might want to use some of the features in master for tool remapping.

What is "master"?
