My apologies, I lumped them together for some reason... Must have been the ALUMINUM TABLE!!!
At least it is a STRAIGHT ALUMINUM TABLE unlike the .007" warped on on the X2
Let's see... Bang for the Buck... Taig CNC Mill versus my Retro'd X2.
OK, Lets compare MY Taig CNC...
Taig, 65 lbs manual, 85 lbs CNC'd. X2, 150 lbs manual, ?? CNC'd.
Fill the column with Concrete... Bolt it to a big ol piece of iron... Weighs more than the X2...
Taig CNC Mill, 30 IPM rapids. My converted X2, 240 IPM rapids.
My belt reduction gets me 90ipm. SMOOTHE 90ipm. Most X2's would self destruct at that speed. I had to get the dremel tool out and grind on the way surface to even get the massive 4" of y travel on the X2. Ya quality product there...
Taig step resolution, .000125", my step resolution, .000100".
My step resolution 0.00003125. Big deal.
Taig structure made of steel and aluminum, mine, cast iron.
Taig has "Rigid tubular steel base and column", mine, cast iron.
Taig has "hard anodized ALUMINUM table", mine, cast iron.
I'll give you this. Wish they would make the saddle and table out of cast iron. But make it Quality cast iron that is STRAIGHT and smoothe unlike the X2.
Taig spindle speed, 1100 to 10k RPM, mine, 100 to 4k rpm.
Mine: ~200 rpm to 13,500 rpm
Taig spindle, 1/4 hp. Mine, 4/5 hp (some say they're overrated, so I'd let you call mine 1/2 hp).
1.5hp treadmill motor. Computer controlled spindle speed.
Taig Speed Control, 5 groove pulley, fixed speeds. Mine, two groove pulley, electronic variable speed (I've been leaving it on the higher speed pulleys and turning the knob to the RPM I want).
Ummm... Don't you mean gears? PLASTIC easily stripped gears?
Taig has LEAD SCREWS, my conversion has ballscrews and preloaded ball nuts.
Mine: 7/16" precision leadscrews from Kerk. .0001" over 12" error. Zero backlash, self lubricating.
Taig has 200 oz/in steppers, mine has 640 oz/in steppers.
Stepper Drivers: Taig uses ???, mine uses Geckodrives.
Gecko 320.
Taig uses "light switch" for power behind the head (that's just funky!), mine has "slam" e-stop switch on the side of the head.
Big red E-stop on my controller.
Taig uses proprietary taper spindle, mine uses R-8.
The ER-16 is an added ($$$) option!
You can get the mill with the ER on it, not that much more.
With R-8, I have all KINDS of options. The truth is, an R-8 spindle wouldn't FIT the HEAD on the Taig Mill. ER-16 on an R-8 spindle? Try this:
http://cgi.ebay.com/ws/eBayISAPI.dll...tem=7589817323 - it'll probably go cheaper than the ER-16 upgrade for the Taig.
Whatever.
Even IF you did your own stepper motors and drivers on a Taig, it wouldn't perform as well as my setup. PERIOD!!! To start, you'd have to put in 5 tpi screws!!! MORE $$$! Might as well go with ballscrews to match mine, eh? $$$...
Mine is better than yours Na Na Na Na!
Sure, a Taig might (and I only say that because I haven't seen them!) have better screws than a stock X2, but my retrofit cost included BALLSCREWS for my X2.
Now see here is the problem with your argumnent. You admit to having no experience with a TAIG.
The TAIG is smoother, more rigid (There, I said it! I could deflect the column on the X2 MORE than I can the TAIG by pushing on the spindle, measured it with a last-word indicator.) Cast iron is great if designed properly. The x2 colum to base is WEAK. The TAIG has way more travel (4"y vs. 5.5"y, 8"x vs. 12"x, 7"z vs. 6"z, your gonna need that extra Z to get that massively over size collet system for such a small machine out)
My setup was $2300, $2400-ish, a Taig CNC Mill (I'll call it "the Taig way") will run you $2155 with the ER-16 option.
Oh, mine cost more than that, but it is all in the control, also didn't spend any time with a file on the TAIG to get it to actually travel the advertised distance.
You COULD get a Taig to perform as fast as my X2, but it's going to cost you more money and time. And then, you still have a Taig..... LOL!!!!
Dude, you are really over the top here.
mgamber, you're comparing a CNC'd Taig to a MANUAL X2 you had, at LEAST by virtue of not considering ballscrews as part of an X2 conversion (that is, if you ever even converted your X2)...
Screws are not the issue. Crappy built quality is.
I'm not a Taig fan, not at all... The design seems very "slapped together". They used aluminum for the table because it's cheap and easy, not because it was the best available material. They used a lightswitch for power because it was cheap and easy. Just two things that stand out. And why a proprietary spindle? TO MAKE YOU BUY MORE TOOLING- that, or it was easier, take your pick. The first time I SAW a Taig product (Lathe) was in some hobby catalog. I looked at it and thought, "What the heck is THAT? It's a MESS!". And the price for what you get? "What a joke!". And the price of the accessories? "You've got to be KIDDING!".
Brass tapered gibs vs steel gibs that look like they were cut with a hack saw... Machine ways that look like they were fly-cut with a dull cutter, weak column to base construction... I can name as many bad points of the X2 as you are the TAIG.
Taig may have been a nice product when there weren't so many competitors, but times have changed and the product hasn't.
Ya, not changed at all (Box ways vs the old dovetail, er16 spindle vs old proprietary, 1/4hp vs old 1/8hp... Dude you don't know what you are talking about here.)
IN ALL, ignatz' example is the most economical, I'd consider my setup a little higher priced than most would like, and Taig isn't even on the list.
