It is more a demonstration on how to program plugins than a useful tool.
Sheetcam laser post processor serial#
HPGL, Gcode, Excellon, DXF, DSTV, SVG are all drawing import filters.ĭNC Tool for transmitting code directly to a machine using serial or an external communication program.Ĭalculator A basic calculator. Knife Generates the tool paths for drag knife cutting. Not many controllers are capable of handling this. Instead of simply cutting around a shape it scans back and forth at a steady speed, firing the laser where needed to build up the shape. In Mach you have to enable the 'SheetCam remote' plugin for this to work. It also automatically reloads you code in Mach when you run the post processor. Mach Integrates with Mach3 and allows you to jog the machine directly from SheetCam. Moreposts Allows you to have buttons for more than one post processor - useful if you run several different machines Depending on what version of SheetCam you have installed you may not have all of these. ↳ QCAD 2.1/2.OK, here is a rundown of the plugins supplied with SheetCam.↳ QCAD 2.1/2.2 Troubleshooting and Problems.↳ QCAD 2.1/2.2 Suggestions and Feedback.

I am a complete beginner at CAD/CAM and have spent the last several months learning QCAD. If I'm going about this wrong, please tell me I have no idea what I'm doing So I guess my question is: Should I be using 'SheetCAM' instead or is it possible to use the CAM feature in QCAD for this purpose? I'm doing some very basic stuff for now as the learning curve is steep. It's never been fired up so this would be the first time. I'm wondering if I've gone down the wrong rabbit hole here as I'm trying to use this for sending output to a plasma table (Langmuir Cross fire Pro). Here in the tool menu, the only available tools are 'mill or drill'. I've moved on to creating the 'Cam profile toolpath'. Ok, so I've gone over the instructions and figured out the 'auto create polyline'. If what I read here is accurate, the kerf of the tool should appear in the arguments for the G41 command-but it doesn't. I don't understand how the create-profile dialog box corresponds to this. I found this (below) web page, which may be a clue about how G41 is used in postprocessing. Seems like it's being used like G92, the position shift command. I doesn't seem to be for tool compensation. Had to move the start of the cut to (0,0) to get G41 under control.
Also, on a simple part, I didn't find G41 in the output.Īlso, why is G41 being used? Tool compensation would have 1/2 the kerf so I would expect to see something like "G41 X0.035" but instead it's "G41 Y12.1304". Now the G41 offset is 0.00ĭoes anyone know how to suppress this G41 output? I want to generate several tool paths but they can't all start on the origin. I move the start point of the polyline to the origin. I moved the part so the corner of the part is on the origin-still have a G41 command. Stupid because it doesn't make sense and a real problem because the FireControl doesn't know what to do with G41. Now, I'm trying to use CAM output from QCAD for a non-test piece. Wrote a bunch of test patterns for the Razorweld Cut45 by hand and post-processed with no problem. It detects the beginning and end of profiles and puts in pierce, retract, and feed settings. It does static, wiggle, ramp, and spiral pierce. So I've hacked together a postprocessor in perl. Here's a simple part with fusion360 + Langmuir post
Is there any documentation/guidance/examples for writing postprocessing code? If you can't provide a postprocessor, perhaps I could build it for you. I think there's an upside for your efforts. If you can get post set up, I'll post about this on the Langmuir forums and make sure people know they can use QCAD seamlessly with the CrossFire Pro. I have an automatic height module so there is a block of code before each cut which basically is torch-height adjustment and the pierce process. Here's the same part with fusion post and QCAD.
