Hello CNC zone people,

I want to use the Taig 2019(CNC ready) mill.http://www.taigtools.com/mmill.html

I want to use the 3-axis servo kit from IMService. http://www.cadcamcadcam.com/index.asp?PageAction=VIEWPROD&ProdID=67

I want to use the Unipower es-101 as my power source. I found this for $40.00 online. I know it's not a linear supply with a large capacitor as recomended by IMS for the best acceleration on rapids, but it can put out a full 25 amps,600 watts from 21 to 28 volts.http://www.servosystems.com/power_supplies_surplus.htm

I am new to cnc, so I have a lot to learn. I will email someone at IMService before I buy, but thought I would post the question here first. I have seen the (customer only?) forums at IMService and found them informative and somewhat helpful.

I would like to add 4th axis rotary table at some point. Would this (es-101) still have enough power?

Any thoughts on the Taig+IMService products are also appreciated, thanks.

I would stick with a Linear supply for your power. Since the servo drives are switching devices you should not use a switching supply. They more than likely interact and cause you grief. I have lots of good things to say about IMService. There stuff seems pretty good. I have a 4 Axis Sherline mill from them. Their after sales support is quite good.
Good Luck

Have you considered building your own controller? The Xylotex I am using on my Taig is really very good for the money, can be had with a 4th axis and the power supplies is simple enough @28.7 vdc 8A. 8 amps is really over kill, proably 5 is plenty. Motors can be purchase in the 270 oz/in range for around $50-$75 each. So worst case the whole nine yards Could be well under $500 with a sharp pencil and a bit of E-BAYing.

Thanks Dave,I will use the linear power supply.Probably a dumb question to begin with. I keep reading more and more reasons why not to use the switching power supplies. I have not read the reason you mentioned yet(at least not that I comprehended) thanks for explaining.

I have this thing (es-101) to power a pump http://www.iwakiwalchem.com/iwaki/products/rd.htm for a w/c PC project. so I had to ask anyway.

I might already have to much on my plate here as it is. Being unfamiliar with all but very basic electronics. I might just buy the $1150. 3 axis, pre-wired, bolt on from IMService.

I ordered the 2019 cnc ready from Nick Carter after seeing one under power at his shop. So at least that much is taken care of..

I have thought about putting together kind of a mixed system, but I was thinking about something a little heavier. The reason being is that if I wanted to retrofit a slightly larger bench mill or small knee mill (probably asian made) I would be able to use some of these components from the Taig project.

Things I would like to migrate would be the gecko servo drivers? and the controll board -Deskcnc? Use the taig to retro fit the bigger mill, migrate acceptable components to bigger mill, and replace migrated taig components with something like you mentioned, as I could find good deals on ebay with some patience.

That is just a thought though and those number$ you posted are a tempting possibility as well for this first system.

People say the geckos are pretty good and I hear good things about deskcnc and Xylotex is an excellent value it seems.

I think I would like to use the gecko servo drives with the deskcnc controller or some other software/controller combo. I think the power source and the drive motors will have to stay with the taig though, if I go to a bigger mill down the road.

Any good controller boards that could 'feed' those hungry geckos if they are using more power to drive bigger servos on a bigger mill?

I am somewhat confused about the controller board after seeing this http://www.cadcamcadcam.com/index.asp?PageAction=VIEWPROD&ProdID=37

then seeing this http://imsrv.com/deskcnc/OtherConnections.png

They both are controller boards? Am I seeing 1st and 2nd generation boards? with the first generation board as pictured here http://www.cadcamcadcam.com/index.asp?PageAction=VIEWPROD&ProdID=67 or is that the 2nd gen board? I dono what I'm looking at here but the bigger board looks like it has more options for secondary operations like coolant, spindle and/or maybe even toolchange? type things.

I plan on using a koolmist system on a timer (Nick Carter has built one of these and it seems to work quite well) I don't need that on the controller card, but it would be nice. Especially if I start trying to add more features to the Taig or migrate to a larger machiene with flood coolant.

Something that would have support for a power draw bar/ATC setup maybe. I was looking at these http://www.littlemachineshop.com/products/product_view.php?ProductID=1944 http://www.littlemachineshop.com/products/product_view.php?ProductID=1663 and started thinking about customizing them by making an easily removeable tapping head and making a seperate R8 taper spindle housing use a power draw bar with the ultimate goal being a small pick and place type ATC. All in due time, heh.

Thanks again for the help guys. I think I am making some progress here.

I have found the answers to the controller board questions I had. Right in front of me, again. I see the newer controller board is the smaller, more efficient board with probably more functionality, Imagine that. There is a nice diagram here http://www.deskcnc.com/controller2nd.html I guess the kit photos (IMserivce) show the older controller boards here. I understand the new 2nd generation controller comes with the kit though. http://www.cadcamcadcam.com/index.asp?PageAction=VIEWCATS&Category=5
