Re: What are the best electronics

Do you want a box of parts from different vendors that might work together and you will be in "discovery" mode. or do you want a integrated package that is from one vendor and one support source? Do you want it with a direct Hypertherm connection for your XP45 or to figure that part out yo...

Re: List of available THCs?

It's a bit like "show me a list of all the cars I can buy with 2 doors" THC's are in one of two categories: 1, Totally Stand Alone (they do everything including fire the torch, touch-off, delays, rapid height , and piercing with little or no control from the motion software. 2. Control sof...

Re: Smallest size bolt hole

That is a loaded question. It all depends on a host of factors. Generally i say that you should not try to cut bolt holes smaller in diameter than 2X your material thickness Plasma cutting is generating an arc, vaporizing the metal and blowing out the material with air. Its not a precision machining...

Re: Using Drawing Pads to Create Graphics?

Drawing pads are great for two things: Digitizing a drawing (hard copy) and those with a problem using a mouse to draw stuff on screen. Its easier to take a large line drawing , tape it to the pad and digitize it there than to scan and do it with a mouse. The larger the pad the more useful it is. Th...

Re: I want to get better quality cuts where do I start?

Don't get fixated on Book Specs. You need to run some straight line tests cuts on flat material with the DTHC in MANUAL and OFF . Make sure your touch off works perfect and you start the cut at -063 . Set your feedrate at book or 90% of book. Then note the Torch volts as it cuts. Also note the quali...

Not sure why you would want to continue to power your controller and move the table when the plasma , lights, stereo , fans and iron lung are all off? Don't you want the motors to stop moving? Maybe it will if you lose arc but then they don't need the controller on anyway. You primary concern is to ...

Re: Cutting corrogated metal

Yes. Climbing a 45 deg slope says your vertical travel is is the same speed as the horz. You need to crank the horz back or the z will hit the edge of the slope. In actuality the Z nees to be a little faster than XY . Never forget that your ACTUAL feedrate is a vector sum of the two axis feedrates. ...

That is definitely one that would not work well with auto trace unless you did some serious bitmap cleanup first, BUT doing it with the tools by hand you can basically just use it as a guide. Its really hard to trace lettering because the human eye reads by shapes and is really quick to catch even m...

Re: Cutting corrogated metal

If this is a stepper based Z and the typical 5Pi you are WAY over the max RPM you can expect. To get 350 ipm you have to spin the motor at 1750 RPM. That is 500 RPM than I have ever seen one do reliably. SO roll it back to about 200 to 250 and slow down the feedrate to about the same. You will need ...

Re: What Z axis is everyone using?

At one point PPLLC had offered a Z with a 12 TPI pitch that results in 23,000 steps per unit. If you use the max RPM of the motor around 600 RPM you end up with about 50 IPM max. Its like being stuck in first gear and you motor will not do more RPM to get you to 100 MPH The lead screw can be replace...

Re: Inkscape Tips???

It's a bit of a nebulous question. The method of tracing is largely dependent on the bitmap to be traced. The level of contrast or the difference between a simple black and white line drawing or a complex continuous tone bitmap all come into play. Then each type of trace has settings. The goal is to...

The Raw Arc Volts on the rear connector on the Everlast are not a direct connection.

Running raw volts across a shop is also a bad idea . They put a ...

A UPS is typically NOT a battery running an inverter that isolates it from the line all ot the time. 90% are standby (like a big transfer switch) that cut in only when the line drops out. They typically do have line filtering so that can help some but bad enough noise and spikes can still get throug...
