CNC Recommendation/Help

[In Utopia]

Trying to get some information or recommendations on a complete CNC setup minus laptop and possibly a torch.
Would my Super Cut 50p work with it?
We are looking to keep the cost below 5K.

I am also looking and so far, find the Torchmate 2x2 system as the best fit for my needs (fabircation of smaller parts). System is expandable in 2x2 modules, so you can upgrade to 2x4, 4x4, and ultimately 4x8, as needs and funds develop.

I think 50amp plasma is too weak for all but sheetmetal use. First, is the duty cycle issue, then is the fact that the torch spacing is a little more than hand held, and you are cutting on water bath. That affects the efficiency of the cut. You definitely need Pilot Arc, and I would go for at least a 60amp or better an 80 amp unit. It may run fine at 50amps, but the duty cycle will be better as the 80 amp unit is running way below top capacity.

the 2x torchmate comes as a set with water table for under 5K, and you can build your own table saving the money needed for the plasma.

Right now I have no problem cutting 1/8"-1/4" HRS using the super cut, and it does have the pilot arc.
Actually I've cut out 2 brackets out of 1/2" plate for a farm implement.
4X4 is definitely what I'd be looking for.

Super Cut 50 is a high frequency cutter, some have been able to work around it, but it will require some work. Duty cycle will also be an issue as well. Go Torch is a 2x2 unit that is made or has something to do with plasma cam. Plasma Cam has a THC that they claim will work with any plasma cutter.

And THC is?

Actually, it's my son who will be buying the unit, and I will be the one using it for him. I think he's going to be getting a Gotorch 2 x 2.
The software is supposed to be a lot more user-friendly than the torch mate.
Right now the price on one is $2995

Well, he pulled the trigger.
Ordered a Gotorch 2x2....it's made by Plasmacam
Got one heck of deal on a new model Powerplasma 70s by Everlast with an upgrade to a Trafimet S75 torch.

Thanks for the input guys.

[In Utopia]

OK, son just ordered his new for me.
He neglected to ask what type interface cabling we'll need, and it's the weekend, so he can't call anyone.
Since I'm in the boondocks and he's not, it would be better for him to buy anything needed to make the hookup from the computer to the torch and computer.
Any info anyone can furnish will be appreciated.

[acourtjester]

I do not have a Gotorch but many of the things you ask about are generic so I will try to help.
To hook the torch to the computer you will need a connection from the plasma unit (CNC output jack common on most). This will be a 2 wire cable to turn on/off the torch using the output of the computer. This will connect to the computer via an output port you will need to find out what the pins are on your controller. This info should be supplied by the Manufacture of both units. I use Mach 3 and the output for the torch is output 1 and that needs to be setup in the software so when a command in the G-code says turn on the torch it know where to sent the signal so it goes to the plasma unit.
Have fun

OK, the controller is a Plasmacam. I understand the USB port on the computer. I think I remember someone mentioning that this cable was the same as a serial printer cable.
The plasma cutter is an Everlast with a USB port on it. Can I assume this is just a USB to USB cable?

[acourtjester]

Hi
Well you can check the manuals for both to find out if that is what you need to hook up the system. Mine used a parallel printer from th ecomputer to the CNC controller and the output from the controller to the plasma was a 2 conductor to the CNC port on the back of the plasma.

[Rambozo]

The plasma cutter is an Everlast with a USB port on it.

Has it been modified? As far as I know, Everlast plasma units come with a CNC port not a USB. Plasmacam has used a 25 pin cable (like old serial printer) but they might very well have switched to USB by now. Unless you bought a complete package, you may have to do some wiring to make all the right connections. It is typically not a plug and play solution unless you get everything from one source, and sometimes not even then.

All I was really trying to do was get some info this weekend since all tech supports are closed.
Don't have either piece of equipment yet, hence no manuals.
Gotorch website has no info or phone number, but since it's made by Plasmacam I looked at the video and my guess was an old style printer/scanner cable, the wire coming out of the controller was hard wired and I'm guessing is USB on the other end..
Long story short (well almost) is I'll wait till Monday, call Everlast, then call Plasmacam to see what all comes with their package. Heck it might be plug and play.
If not it's a 112 mile round trip to the nearest place to get cables (Radio Shack)............the price you pay for country living.

Again, thanks for all the input. I'll put it all on hold until Monday, in the mean time I'll get started on a roll around table for it.

If you bought the Plasma from Everlast, you can get the manual online. In fact you need to as the manual that ships with the unit is not as good as the online version. It will come with a blank CNC plug that you can wire up yourself. If you bought the plasma from Gotorch, they might have done this for you. Typically you will need to connect a few things with screw terminal blocks and wire. This is not advanced to the point of plug and play, for most setups. Gotorch doesn't do phone support anyway. You will have to use community support or figure it out on your own. It's a price point thing, and they are pretty upfront about it. They even direct you to buy direct from PlasmaCAM if you want that kind of service. If you don't mind tinkering around and learning how this works, you should be fine. If you just want to start making parts, you probably bought the wrong unit. The cables from the computer to the controller box should be included, but you might need a different length depending on your setup. The CNC port on the plasma to the controller you will probably have to wire yourself. Everlast includes one plug and Gotorch should include the other or they use screw terminals. CAT-5 wire is usually fine to interconnect shielded is better. Since you are in the sticks, I would guess you have a pretty well stocked workshop, if not, you will when this is over. BTW these days getting specialty parts is as close as your computer and mailbox, way easier than in the past, but you do need a little patience. In fact it has wiped out many local sources. RadioShack will not be of much use to you for this kind of project. Digikey and Mouser to the rescue.

Gotorch says they still use a parallel port for control. So be sure your computer has one as they are getting rare.

Hi
The printer cable you nee is not a standard printer cable from old (DB-25 to centronics).
What you need is DB-25 on both ends one male and one female.

Thanks guy, you've been a lot of help.
Downloaded the manual on the new 70s (as I did for the Super Cut 50 I now have), but can't get a full manual for the Plasma Cam system, just bits and pieces. The only thing I could find from them was a snipit from an archieve file, not the whole manual.
Used to have several of those old printer/scanner cables, don't know if I saved any of them. If I did, they are at my other residence back in Pasadena. Heck, since this is the sticks some of the people up here may still have some of those old cables.
Think I'll take the day off and move some caliche for my carport pad and give what's left of my brain some time off.

Just ordered it.
This is the kind of help I need from this vast pool of knowledge.

Keep the suggestions coming.

[EmptyNester]

I didn't see anyone respond to your comment about not needing a laptop.

If you use Mach software to drive the table, it needs to have a parallel printer port. Laptops don't have parallel printer ports on them. And, you can't use a USB to parallel port because they are too slow.

There are some third party solutions (SmoothStepper, etc) - but they are more invovled and more money. Best case is if you have an old XP system laying around.

[In Utopia]

Good catch.
Just happen to have 2 extra desktops running Pent.4 and XP pro.

Man, I've got to many irons in the fire for an old fart.
