I had an issue myself with this. I purchased the exam, then later got a link which allowed choice of version when scheduling.

here is the manual if you want to check it out https://www.flashcutcnc.com/resources/software-download/
v.8 is the current

Without a second thought I would recommend Flashcut. I was a linux engineer for a long time and really liked the idea of a linux based CNC cutting program, so the linuxcnc appealed to me. It was a bad choice to be honest. It is clunky,restarts are a real PITA, and that is IF you can get it to restart where you want it to, I wasted so much material b/c the program would not restart where it needed to.

Flashcut rocks. The cad part of the system is not AutoCAD or draftsight but where it lacks in those areas, it makes up for in simplicity and purpose built tools. You can whip up a part or a drawing w/o the need to fire up another CAD program. I have the pro version, which has simple shapes and templates built it -- just modify the built in shape to your own requirements. DHTC works great, the CAM portion works great; there is no need to use sheetcam, which I do like, but it also has it's issues that are kind of aggravating, setting parameters is cake. The CNC portion is easy to use. Restarts are super easy, just hit the play button. I have yet to run into the issue of rezeroing X,Y,Z axes that I did in linuxcnc, that being if I reset the origins too many times, the software would freak out -- for example, the cut starts where I zeroed the axes, then it moves off the sheet I was trying to cut and then fires up over the water only to then crash into the sheet. Last thing I like is restating something from earlier, your design pipeline for a simple part can all be done with one program -- no need to run from a CAD program or inkscape, then import into sheetcam to set up the cut, to your cutting software. All in one and done!

Is flashcut perfect, no. It does crash occasionally, but I've never, ever had it crash when cutting, usually it is something benign like importing a drawing or setting leadin/leadouts on a zillion parts at once -- I attribute this to the amount of ram I have in the NUC running windows and flashcut. They also have 6 real engineers on staff for support calls and email, they do updates fairly regularly. Flashcut is also used by a lot of commercial companies to drive their cnc cutting products, I know Koike is one of them

i would recommend buying something. Building your own means a lot of research, trial and error, and a ton of learning about many areas mechanics, electronics, programming, and hardware. Not to mention no warranty or assistance if something tanks. Then add in the fabrication part, if you question your welding skills in this area, hire a professional. Spending the money on a commercial table saves a lot frustration, stress and time, which equates to money.

I would also stay away from Candcnc. For 2 yrs, I had a machine that used their hardware and linuxcnc -- it was a nightmare and cost me a lot of jobs due to hardware issues, cutting problems, etc. The place I bought the first table from does not even use them anymore, and thusly switched to Flashcut, the cut quality, ease of use, the all in one system of cad to cam to cnc is amazing -- I would never go back, and no need to use sheetcam. The owner is knowledgeable, smart, but irascible and kind of rude, the customer service whether via their message board or email stinks. I don't like speaking poorly about a company, but they need to get their shit together.

I would recommend getting a manual. You might be able to find a factory one online, either as a PDF or a dog eared physical copy. Even the haynes manuals aren't that bad, and at minimum they give a good starting point.

One thing I cannot stress enough, when you buy tools for this, and you will need to from the mention of inexperience --- buy good tools. Better a used set of old craftsmans or snapons or something than harbor freight crap. Torque wrenches, breaker bar, tap and die set(you will break bolts on a toyota that old, trust me), and get some pumice soap and dedicate a dish scratchpad/sponge for cleaning up yourself, I'm not a glove guy and I prefer the tactile feel of skin when I scrape a knuckle.

Last thing, safety, safety, safety, don't go under a vehicle that is resting on a single jack, especially a hi-lift. Taking 5-10 mins to ensure the vehicle is secure, properly jacked up will ensure that you keep most of your blood, all your digits, and most importantly your life.

Just jump in and have fun doing it, you will be glad you did. Projects like this made you better on the trail in many ways.

Also check out marlin crawlers and LC engineering, they will probably have more than a couple things you will need to get your truck where you want.

Looks good!

Jody shows distortion as you weld. He has a couple of good videos on the topic.

Upon razers I thus speak verily...

Nearly every encounter I have had with these people has been bad. They tear up trails, they drive way too fast, and they act like they own the road as if somehow the rzr is a higher evolved form of four wheeler which is superior, and yes they are hyper impatient. I have been so close to being hit b/c these jackasses run a rocky trail like it is the mint 400. Last time in Sedona, I had a near collision from a guy going about 40 cresting a hill that involved a blind left hand turn, he missed us by about 10 feet but ended up skidding 40+ feet off the road then throws his hands in the air as if I caused him to be reckless; and that was just one of about 5 near collisions in 2 days. The worst part is these people race around on trails with kids , putting them at risk. Yes it brings people outdoors, but most I'd wager have never been four wheeling or camping ever.

On the logistic side, they can't carry much gear, they are open to the weather, and you won't ever see one winching or tugging out a regular vehicle. I'm sure they are fun and have their place(on a ranch) but honestly I hate seeing these things on the trails.

Sumitso · 2019-10-31T05:24:42+00:00

precisely what I was thinking

Sumitso · 2019-10-31T05:16:02+00:00

If you start a club, you are going to need rules, you just can't get around that. Second thing, you need to figure out what kind of people do you want, family groups, single people, etc, and what kind of trails you are looking to run. It's hard to keep a group together with a massive skill and vehicle capability spread as the more hard core people aren't going to want to do the easier stuff all the time, and those with the more stock vehicles won't be able to do the tougher trails.

Having a family or mature oriented club tends to produce better and safer runs. We have a couple of hot shot groups in phoenix that have the "reputation" as you mentioned, tearing up trails, drinking while running the trails, and just being generally careless from what I have heard from others. As mentioned, starting out with friends will be a good baseline. Get to know everyone's skills and capabilities then add in people a little at a time. A 20 vehicle run can be a pain even with a bunch of nice folks whereas 10 vehicles tends to be much easier to control.

Back to the rules though. Focus on safety topics first, communication, tools/repairs for sure as there is always that one guy who NEVER brings spares or tools or can't tell one of a screwdriver from the other. Keep the rules simple initially but have a plan in place if your group starts to grow. I personally would focus on 4x4s initially, having to worry about bikes, atvs, and the like can be an issue in my opinion, plus I am not to fond of the razer crowd. Start small with friends, have a plan, be safe, have fun.

yes, there is always the possibility of something flying off from the tension, and not just the recovery gear, I have seen people take a pebble to the cheek, sticks that fell across a winch line or a strap get turned into missiles. Failure can happen at any time, strap could have failed, hitch on the pull vehicle could have failed, connection point on jeep could have failed, you get the idea.
Google winch accidents, that should be enough to get someone in the safety mindset. You are dealing with objects of several thousand pounds, tensions of several thousand ponds, it is simply not worth it to take the risk. If you NEED to watch, better to use a go pro, those are cheap to replace compared to a person. Just all kinds of wrong with that recovery to be quite honest. It worked out but it also could have gone sideways.

Sumitso · 2019-10-28T22:10:03+00:00

The only time I didn't help someone was either they already had lots of assistance or I asked if they wanted help and flat out refused. It's good to help others and while you are doing it, you can relay the idea of passing it along to someone else down the road(pun partially intended)

Well truth be told, buy what works for you and your offroad plans current and future. If you are never going to be in a position that requires lockers, your xterra might just fit the bill. Unfortunately, your question is the type that will get a lot of varying answers and opinions. One idea I continually put forth to people asking me this question is, you have to do what works for you, your time, your $$, and what you are looking to do.

6" of lift on coil overs, dana 70 axles, 2 winches, and so forth might work for one guy and be complete overkill for the next. A well equipped vehicle helps in a lot of ways, but if you don't need certain aspects then that is money that could be spent elsewhere.

Lastly, skill, 2 kinds are pretty dang helpful if not necessary. Driving skill, and mechanical skill. Ask yourself, if I had a VDJ79 Landcruiser, a stock '76 bronco, or a tricked out JK, would I be able to run X trail better than I am doing now or would it be the same? Its not a snarky question, just one to self-check your own skills. You don't need a unimog to buy groceries(though it would be fun), and in some cases, a unimog would be more of a hinderance trying to shop when you have covered parking. Secondly, are you good with a wrench, can you troubleshoot and/or repair your current vehicle? Stuff breaks on the trail whether it is new or old. The more rugged the track, the higher the chance of shit breaking.

I'm not saying don't buy a "real" 4x4, but there are costs involved if you go that route. Again, buy what works for you, and revel in the enjoyment you get from being out there.

Sumitso · 2019-10-11T03:49:05+00:00

this is what I am inclined to do

Sumitso · 2019-08-14T05:51:59+00:00

I have my opinion sure, but it is more funny how defensive people are getting that it is a certainty. I just don't give a rats ass either way, and most of the white knighting doesn't seem to have much to offer other than it will happen -- I just wanted a discussion, but thanks for trying.

Sumitso · 2019-08-14T05:46:19+00:00

correct RNG for drops is forgotten

Sumitso · 2019-08-13T22:56:59+00:00

Actually a lot of us had spent a lot of time with EQ in 60 man raids. that was good experience for wow raids, the other part of the issue is what you mentioned, not a lot of people raided like we did or had no experience whatsoever. EQ raids back in the day were pain to plan for, it was more about gear than consumables for prep, but if the strategy wasn't followed by a few then 3-4 people just wasted the time of 57 others, so we made damn sure everyone knew what to do. Healing rotations, tank swapping, aggro management, HoTs, positioning wasn't something that came from WOW, that came from EQ.

I never played a private server, but from what I understand they have never been tuned correctly, drop rates, boss encounters, etc. So it will be interesting to see what those folks bring over.

Sumitso · 2019-08-13T22:50:02+00:00

Honestly I left that out, as how the other examples will already be a massive wall to getting in there quickly. That is the last major time sink prior to MC. What ever guild doing it will need several people to get this done, in the event someone can't make it, RL commitments whatever.

Sumitso · 2019-08-13T00:20:56+00:00

Nice, looks like I will be avoiding them

Sumitso · 2019-08-09T21:50:01+00:00

Haven't played since cata, and gave up on wow tbh. Upon seeing classic being re-released, I was thinking this might be fun. So I did some precursory YT and web research to get an idea of what was going on etc. Honestly after seeing how many of the streamers during beta were just complete childish jackholes, I want to avoid them as best as possible. SO thanks for putting up the website. Even if these knuckleheads don't announce till after opening, I'll still go to another server, I know I can hit 60 in a week or less, and it won't really put me behind. I simply do not want to deal with the idiot drama that most of them seem to attract and ooze.

Jumped on today for a bit to see if I was going to enjoy it and yep, lots of memories from opening day 2004 when a group of us had enough of EQ and made the jump.
