CAMCUTCNC FAQ's
We Have Been in business since 1993, Primerea.com We moved into CNC
manufacturing in 1999 and our Camcutcnc line of products went into production in 2001. We have setup
to be in the CNC business for the long run by manufacturing as much as possible in house and passing
the savings along to you the customer.
Do we just sell kits?
We sell several different size machines, most people having fabrication skills opt for the kit form
to save money. We also offer any kit in finished form as well as our new bolt together and Profab units.
What else do I need to purchase to get up and running?
All of our products come as a complete package. IE. We include all of the hardware and software necessary
to design/draw a part then convert the drawing to G-code which controls the machine. If you purchase a kit,
you will need to supply the steel to build the table and a computer to operate the table. If you purchase a
bolt together machine you will only need to supply a computer. The ProFab H20 machine comes complete including
a computer.We do offer options for advanced users as not everyone will need the advanced options.
Why are your kits so inexpensive compared to others?
In house manufacturing. We CNC machine the parts for our kits and build the CNC controls in house,
rather than purchasing these items as most of our competitors do. This also allows us to
provide better service should that be necessary. You will never be directed to a third
party vendor for support. We want every Camcutcnc installation to be successful.
Do your systems use stepper
motors or servo motors?
We use stepper motors on our kits and bolt together units, for their accuracy,
fewer components and ease of setup by the customer. Our ProFab H20 units have a heavier
gantry which can support multiple torches for serious cutting. We use servo motors for their
speed, smoothness and power. Our ProFab H20 units are factory built and calibrated.
Both types of motors are accurate when properly sized for the application.
Can I use my hand held plasma torch?
Yes you can, with our optional hand torch adapter. Our hand torch adapter overcomes the
drawbacks inherant in most hand torch holder designs. Most designs obscure the plasma tip
and are very difficult to get the torch aligned perpindicular to the work. Most of those designs
require you to re-align the torch every time you change consumables. Our design allows
you to see the torch tip and the torch holder quickly pivots 90 degrees for ease of changing consumables.
It also allows the torch to be used manualy and then be easily reinstalled on the machine without
realighnig the torch.
Machine torches don't provide any difference in cut quality, so It really comes down to
personal preference as to which type of torch you select. For multiple torch units
machine torches are prefered.
What is the waranty period on
electronics?
The electronics have a 1 year manufacturer's warranty. The rest of the
mechanical parts are designed for greater loads than are encountered in this application
and are not prone to failure. Almost all of the machine's mechanical components are
available from an industrial supply house.
Do I need automatic torch height control?
There are a number of factors that contribute to the decision as to wether it's necessary.
For smaller machines 2' x 3' and 4' x 4' it is usually not necessary. On larger machines
a torch height control of some kind is desireable, depending on the material thickness and
the number of pieces being cut from a sheet. If you usually cut 1/8" or thicker material,
the motorized Z axis will probably due the job for you. If you are looking at a multiple
torch system or primarily cut 1/8" and thinner material or a large number of parts from a
sheet of material then the ARC VOLTAGE THC is the better solution.
Our automatic torch height controller constantly monitors the arc voltage at the torch tip.
This voltage changes as the distance between the torch tip and the work changes.
The torch height controller has it's own built in computer that monitors a reference voltage.
This reference voltage is set by the operator. During the cut process the built in computer
adjusts the torch up or down to maintain the reference voltage and corresponding tip to work distance
set by the operator.
Our Z axis is is the same torch holder but with a manual remote control. The operator has a
hand held pendant with up/dn buttons which can be activated if the tip to work distance
needs to be adjusted.
Both our Z axis and our Arc Voltage Torch Height Control include an automated Z axis feature
which allows your PC to control a router, roto zip or plotter pen/pencil that requires coordinated
x, y, and z motion.
What kind of computer do I need?
It is best to use two computers, one in your home or office to develop your shapes, and
another computer in your shop that is dedicated to your machine.
The computers should be at least a 200 mhz Pentium.
Used Pentiums can usually be purchased for less than $100. Your plasma cutter should have a pilot arc
as a touch start is not supported. If you do not already have a plasma cutter we recommend
Hypertherm products as they do not create a high frequency interference problem.
Can I use your CNC system with oxy-fuel?
Yes you can. An Oxy/Fuel oxygen kit will be required to activate the cutting oxygen.
Plasma is great for cutting thin material at high speed. Oxy/Fuel will usually do a better
job on material 3/4" and thicker plate. At that thickness the speed of the Plasma cut
process is nearly the same as the Oxy/Fuel process, but the Oxy/Fuel won't leave a beveled
edge that may happen with the Plasma process. Our DXF to Gcode converter has built in support
for Oxy/Fuel.
