Re: Break Point

LinuxCNC also has the ability to "Run from here". As the code scrolls in the G-code window the current line is highlighted. Right click on that line and that option shows up. Just a warning though as depending on when the job was stopped you might need to start on a previous line to make sure the bi...

Re: CUTTING AN ARC IN X-Z AXIS

In my experience, the fluting toolpath cuts more of an elliptical arc than a true circular arc. The moulding toolpath can cut a true circular arc.

Re: Horizontal lines from flattening a work piece

It will help to set the direction of a pocket to raster parallel to the grain. You may still end up with a slight scallop if your bit isn't true to the cutting plane, but sanding the board will be simpler.

Re: Altering a batch size of circles

You don't need a gadget. The offset tool will do the job. Select all the circles you want to increase. Click on the offset tool. Pick outwards. Put in half the amount you want to increase the circles by. If it is .3mm then use .15mm for example. Choose Delete Original. Click on Offset. That should t...

Re: Help with how create tool path and machine this part

The VCarve toolpath looks like it could do the job. You'll need to try it with your vectors, but I've attached a sample I did using Aspire 9.519. I used a 60 degree V-bit. Imported your bitmap image to try and get it close too the right proportions.

Re: zig zag profile tool path

That is pretty darn good 4D! In the code generated only one "extra move" that I could see: N130G1X0.4651Z0.0000 'Retract to Z0 at feedrate Yep. Where it lifts up is the start point of the vectors, and that is where the ramp starts even though the ramp length is effectively zero. Give me a little wh...

I want to lay out and cut 6 .25 wide dados 8 inches long and .25 inches deep in a piece of material that is .75 thick. using a .25 end mil. I would like the tool to make 1 pass at .125 goto the end of the vector then plunge down to .25 and come back to the start point and then move up to the next v...

Re: zig zag profile tool path

No, and yes. The yes version just requires adding more vectors to tell the bit specifically what to do. The fluting toolpath can be set to go back and forth, stepping down as you wish. It requires a centerline to follow though. Make an offset line by 1/2 the diameter of the endmill you want to use, ...

Re: Moulding toolpath question - rosettes

It seems strange to have to add a feature to the rosette that isn't there just to get the toolpath to cut completely. When they first added the moulding toolpath I also was puzzled why the bit wouldn't pass over steep sloped ends and such. It took me a few days of playing around with it to realize ...

Re: Moulding toolpath question - rosettes

I added a hook at the bottom of your vector so the bit would travel down to the end of the slope. I also set material above the cut to approximately .3" so it would start at the level your pocket cut to. The moulding toolpath keeps the bit tangent to the vector, but won't move the center of the bit ...

You might look at the DJI OSMO Pocket camera. It is capable of tracking the spindle as it moves around, and capable of 4K video. I've used it to make a few videos to show my students what the CNC is capable of. There is also a wifi/bluetooth adapter for it so you can control it wirelessly with the p...

Re: G93 for Rotary LinuxCNC Post Processor

I run a machine using linuxCNC that had a rotary axis. The slow spin once a toolpath starts is because it general is converting X (inches/min) to A (degrees/minute) in the post processor. If the bit you have selected has a feed speed of 200ipm for example, that will equal 200 degree per minute on th...

Re: Any 5' x 5' CNC machines out there?

I know that probotix.com frequently makes custom sized CNC for customers. You might have your friend email support@probotix.com. I own one CNC made by them, and work with three others made by them and have always been happy with support provided over the years.
