Re: Newbie needs to know how to load dcf file into candcam

If its a CommandCNC (Linux) computer you have SheetCAM , Q CAD, Inkscape and Libra Draw on that computer. ArclightCNC.com has training videos on how to import a DXF into SheetCAM. Inkscape will also import DXF and export SVG that SheetCAM understands as well.

Re: insert text into a shape

There may be a way in BobCAD but typically most CAD programs won't let you do fancy stuff. Both Corel and Inkscape are true DRAWING programs versus a CAD .

Re: CAD HELP

Have you tried EXPORT? Autocad only SAVES in native file formats. You should be able to pitch the version of DXF you want to export in. Use older version. Depending on whaich CAM you are using you might consider drawing the parts separately and exporting them separately then nesting them in your CAM...

Re: Losing steps and my sanity Rtech plasma table

Its a MACH3 based unit with THC from (I think) Vietnam . i recognize the custom buttons I did years ago for our MACH3 screens for plasma. No idea what they are using for motor drivers and that is probably where the trouble is.

Re: Torch diving only on the holes in 1/2" thick steel (CommandCNC)

no not really. Its built into the software and you just set the soft pierce % in the Operations . I would try 70%.. It slows down the plunge by the same % which might not be enough so you might need to alter the plunge rate . The idea is to start the pierce and pool the metal so it does not blow str...

Re: Torch diving only on the holes in 1/2" thick steel (CommandCNC)

All you have to do is set the MIn Cut Length for DTHC in the SheetCAM Operation to a value GREATER than the hole circumference + lead-in. It's better than a cut rule because it never turns the DTHC ON if it violates the setting. The software knows in advance how long a cut is and it turns the DTHC O...

Re: Belt reduction suggestions

The SD is as close to not having a THC as you can get . YOu have NO control over it before or during a cut. My option, but gathered from other posts on other forums from SD users. One look around the finished table vendors and the builders here, you won't find very many trying to use MACH4 or the SD...

Re: Belt reduction suggestions

At slower speeds the wave and divets aren't as pronounced. Thicker parts seem to cut cleaner but they arent very intricate. Yep, Wobbly mechanics. Possibly oscillating Z from THC. The faster you cut the more inertia you have and that can cause vibration on any thing that is even slightly loose. You...

Re: Smallest size bolt hole

You do offsets in the CAM. You simply make the kerf width wider and it widens the toolpath out . You would make it .005 nor kerf width to add .01 to a circle. Since kerf width is a tool parameter you may need to create a new tool with different parameters to make it cut specific hols (or grups of ho...

Re: Smallest size bolt hole

There you have it D.O.T! all you have to do is spend another 100K+ on waterjet and CNC punch press machines and you are good to go! I saw several combo CNC punch press/ plasma machines at the last Fabtech show. One had an auto material loader to boot. Cost about as much as a moderate new house.

Duh! I should have noticed which sub forum this is in.....LDR. Dan can help you address the square tube cutting issue. LDR has more experience than most with building and using rotary plasma cutting. Bendtech may or may not be the answer for non-round cutting.

Re: Belt reduction suggestions

I don't think wavy cuts are from the wrong belt ratio. Belt ratios are only part of the equation. YOu have to take into account the drive gear DIAMETER (DP) . It steps UP speed at a ratio of PI times the diameter. Rotary torqe decreases with the same ratio in reverse and linear force is rotary torqu...
