making CNC is what i did. it works great. i dont have tons of room so tiny machines are all i can have (for now. i want my own cnc shop)

You done anything fun lately?
nice. i have thought about getting a precision mathews mill to convert because my little mill is being quickly out grown. probably smarter to try and find a space and get a REAL mill though

i would recommend running away from mach 3-4 and go for linuxcnc + mesa control card. its WAYYYY better than mach but is much more involved in setup.

look up "linearmotionbearings2008" on EBAY. he's a nice guy from china who will cut a piece of ball screw for you any length and even machine the ends if you want him to. he has several types and diameters. its cheaper than the mcmaster carr stuff and is plenty accurate for hobby milling.

Just curious because despite the cost of new cnc's, used ones can be gotten at auctions or from shop closings for literally pennies on the dollar.
Like a couple grand will get you a cnc that functions totally fine. It will be 20+ years old but will still work great.

The Mathews units look quite nice and have some good reviews.

Yeah, I'm familiar with Mach3 and would happily opt to upgrade to Mach4. I had already decided that I didn't want to delve into the hassle of linux.

There are several guys offering similar services. Always nice to know of another vendor.

However for me, I'm already upgrading to the a Haas as some things have changed on my end. Looking at a VF1 tomorrow morning, and debating between it or a Super Mini Mill.

went to an auction a few weeks back for a VF5.

They also had a '99 VF2 in great condition, one shift/day 5 days/week that went for $3k

linuxcnc is seriously alot better than mach/windows and is worth the effort if you want a robust controller. IMO its as reliable as all the "real" controls i have interacted with (fanuc) and much easier to use (than fanuc) due to a nice visual UI that makes sense. mach# is a joke. be prepared for lots of crashes when windows lets your machine keep going when you tell it to stop.

'06-'10 is the sweet spot for Haas, in my opinion and experience. 4 out of my 5 Haas are in this range.

i'm also fully DONE with Haas. after mine die, that's it. sick of dealing with that ****ty company and their ****ty factory resellers with moron service techs. thankfully, i have a really good independent Haas tech.

their new machines are becoming a trashcan of chinese junk internal parts that don't last.

^hmmmm, I've heard the opposite

No clue from experience as the '99 VF-5 I got there is our first, but it seems great so far after a few months running.

Chinese junk seems to be in everything frankly, shame.
China has been working over time getting ready to supply the US it's Xmas though. Container ships back and forth providing Amazon with the garbage it needs to send to US customers to cycle through their households for 6 months to a year before going to a landfill for the next 10,000 years.

Every machinist I've known has bashed Haas when it comes to precision but recommend for getting started due to support/commonality.

Trust me, a DMG Mori would be on my list of if money wasn't an issue

For now the VF1 or Super Mini Mill will have me covered for the time being...I'll see how the next year goes and if the money is there for an upgrade to a new machine.

interesting how that money thing works out in the long run.

Last auction I was at was a place with two dozen Mazak's all brand new within the last 10 years. Some looked like they were just un crated.
Every bell and whistle on every machine, tool probes, camera/monitor systems, part catchers, dual spindles, live tooling, etc
Best equipment I've ever seen under one roof.

aaaaaaaaaannnnndd. . . . .they were liquidating their assets for dimes on the dollar

TBH i would take any "big" machine right now in reality you don't need extreme accuracy for alot of parts other than a few critical features here and there. HAAS seems aimed toward guys who are new. they even have the lathe that is "manual no need to know g code" they are the megasquirt of cnc machines.

I completely agree. I'm no expert at running CNCs as I've always been on the design side of them professionally. It also makes it great as Haas machines are thus plentiful.

the older ones seem decent; it's the newest ones that are chock full of chinese junk. i would trust an older Haas, if it is well maintained. i just like the newer control that was introduced in '06. and then hated the next control change in 2011. hahaha

honestly, seeing older 90's Haas on the used market is a good sign they're at least lasting that long, but a machine is only as good as the parts availability for it and your service tech. treat the Remote Hand Jog Control as if it is made of gold.

Our Haas are precise enough for what we do, but my biggest gripe about them is their longevity and their abysmal factory support.

i've had horrific problems with the ****ing losers at the Haas Factory Outlet here in CO. pure cry babies. they try to bully me for not using their **** service dept and have shipped me incorrect parts just to try to sabotage my independent service tech.
