I posted this in another area but thought I might more info here:
I have an opportunity to purchase a DoAll CNC mill that appears to be in great shape but I wanted to get info on the DoAll line. Are they hard to get parts for? Are they junk? Etc? Here is the excerpt on it:
DoAll CNC 2000 mill, 3 axis, Dynapath System 10 control, conversational programming, CRT, many 3D shapes as canned cycles, Graphics option, LIKE NEW condition, 9" x 49" table, variable speed head, NMTB 30 taper, power drawbar, handles on X and Y axes for manual operation, tooling included $ 7,000
Here is the link for the pic:

Thanks in advance for any help.

You photo is missing critical clues but from what I can see it appears to be the same old Tawainese iron that a gazillion other distributors used to use, such as SuperMax, Kent, Acer, etc.

I could be wrong but I don't think the Dynapath Delta 10 is still supported. Much more desirable would be the Delta 20 series. Still, if truly "like new", $7K is reasonable for 3 axis CNC of that ilk. Better however would be to pay just a little more for one with newer 20 series control.

You sure it's no. 30 spindle ? Most of those of that design were no. 40 spindle.

I think $7000 may be a little on the high side.

With the System 10 control this machine must be from the early eighties. Dynapath no longer supports this control, one of their employees left the company and bought the rights to the control so support is still available. It is a fairly old control though, although I think you'll find it has features equivalent to what some of the new controls offer. Even at it's age, it'll run circles around any of the "hobby" PC based controls that seem to be so popular.

In that era Doall tended to use pretty good iron so there shouldn't be problems there. I doubt parts would be available, it's unlikely you would ever need any that you couldn't make yourself.

Again, as I said, the price is a little high for such an old machine. But even with the high price, if it's close by and you can see it run it may be better to bite the bullet than buying a machine at a better price that's half way across the country.

I am not sure on the spindle. Thanks for your reply. Are you saying that the control part may be unusable in a way?

Here are so more pics:

It does appear to be no. 30 spindle from the photo. Now I can tell it's not quite the "heavy duty" iron I thought, but more the standard Bridgeport size machine. So, I would now agree with DR that it's just a little high. $5,500 to $6,500 probably more appropriate.

Unless of course one thinks in "eBay" price terms for CNC, in which case $1,500 about right http://bbs.homeshopmachinist.net//wink.gif

"Are you saying that the control part may be unusable in a way?"

As long as the control is currrently functioning you'll probably be okay. They're reliable.

Note this is a System 10 not a Delta 10. The Delta series came after this series.

It does have conversational programming which is very nice. I believe the System 10 controls can not use standard Gcode programming though. Not a big problem if using a CAM program with an editable post processor. It's just a matter of translating the Gcode to a conversational event, no big deal. For parts without irregular contours you can program this machine right on the floor faster than the average CAM user can boot up his software.

Outfit in Pa?

I think that is the outfit my bridgeport came from.

I paid too much for my machine.

Other than that, he was friendly and honest. Met me after I drove all night, loaded and helped tie down my machine.

I came home with my machine not really knowing what I had bought. With my background I knew I could make it work, just the cnc motors/ball screws and a tight machine was all I really wanted. I got that.

He was upset when I cut the machine into parts and ebayed the extras. I emailed him and let him know what I was doing. He was not supportive, I guess he had saw too many disastors. OR: not that versed in robotics. He did want the spare parts but didn't pay what other ebayers did. He did have a whole rack of kwik switch tooling, and other nice machines.

I think he, Like I have been doing lately is/was buying and selling machines.

We have a index cnc at the shop. Not really even looked at it other than to take pictures thou. I got the scotchman ironworker at the same auction and have played with it a lot.

I built that dolly to move machinery in less than half the time of sawing it with my $200 saw. Since I have been down (sick).

The Northeast USA is a rich spot for used machinery. Look in the classifieds online. You will find bargains unseen in the rest of the USA. The people I.you are looking at are online, they bought thier machinery somewhere. If you want a real deal, go to the source.

sorry lets try it again

I have a 1984 Lagun 310 in my garage that has the system 10 control. I have had it for about 10 years now and had only two problems with it.The problem was with the speedchanger (which you dont have), and now I have a ploblem with down loading to the machine.This problem accured after I up graded to a new pc. I have not figure out this one yet. I can only down load one page of info them stop. I believe it may be a hand shaking problem? I have used Bobcad cam to program it, then run it through a filtering program to change to a conversatioal format. It work great.I have used this machine to do make many one off parts.If I were to buy again I would probably spend more money and get a 3 axis bed mill. The ones that have a z axis head that rides on ways, with a BP head attached to it. This kind of mill allows both manual, and cnc operations. These machine cost about 15-20 thou new but if you are serious about making some money with your machine, then the extra money spend know will made your jobs easier and faster to make. thus paying it off will be faster. anddsn

I've run across a local "Tree Journeyman 325, 3 axis CNC Mill with Dynapath Delta 20 5 axis control. Variable Frequency Drive with 6,000 RPM CAT 40 spindle. 10"x44" table. - $6200". From the serial number it looks to be a 1985 build.

A photo I was sent of it is at:

http://www.eurospares.com/graphics/metalwork/fullview.jpg

Since I had pretty much nothing to go on but eBay prices and what a friend paid for a Shizouka (about $3K) I was figuring that $4k or so for the Tree was probably the going rate. Maybe $6200 is fair for a nice condition machine.

But if I consider a used machine it is as a candidate for a modern control retrofit, and so $2-3K is my idea of what I'd be looking for, depending on if the OEM servos and the iron were in good condition. The Dynapath has no value to me, though I guess if someone wanted to retain the control then the higher price that is being asked could be justified.

Maybe that info can be of some use to you on pricing the DoAll machine.

I wouldn't mind some comments on if I'd be way out of line by telling the guy that unless he could drop the price by 50% it isn't really what I'm looking for (a nice machine with dead control would be fine). I don't want to insult the fellow, but $12K for a control only (or $14K with servo motors) retrofit plus a machine without a manufacturer still in business starts to make a nice new import with the same control look appealing.

If I can save $8-9K I'd consider the Tree, but if the savings starts to get down into the $3K or so range a new machine instead of a 20 year old orphan looks a bit more attractive.

cheers,
Michael
