About flipping: the flip operation accuracy depends on the perfect squareness of the stock to be machined. Never 100% thrust that. Precise flipping is usually made by using fiducial pins along the symmetry axis of the part.

Drilling a hole in the center of the dogs would allow air through the dogs and thus prevent the air suction that is making it hard to remove the dogs from their holes, just a thought. 😊

Great video with very clear explanations. I've been trying to figure out how to do more accurate two sided machining and this gives me some ideas. Thanks for making this!

If you buy inserts with "knife threads" they will drive directly ionto the MDF eliminating the need to tap the hole. Plus the knife threads are wider than traditional threads to grip the MDF or other soft wood better. Not so with hard woods...

The fact that you can flip the piece and perfectly drill all the way through makes me want to see you try and make a 2-sided PCB with that CNC...

@edwardholmes91

That would be great! I think you'd need to make a jig to hold the PCB in as well maybe? As they are usually around 1.6mm thick.

Presumably you can tighten the fit of the holes by applying PVA once the holes have loosened too much.

Brillant.

One of the best things for CNC is importing your CAD model into a CAD model of your clamping bed with your holes, inserted dogs and the like. It is a great way to see if there is a crash when you simulate from there. Also helps to see how you will clamp it up easier in my opinion.

First to view and comment. Your improvements are great time saving improvement to the original equipment. I'm surprised it isn't offered by the manufacture. Thanks for sharing your work.

Some professional CNC machine have air driven pop up pins. I'm sure you could make something similar. Also the best calibration test I've done on my machine is to cut a square frame positioned diagonally from the x and y axes, afterward measure between the diagonal corners with the callipers and comparing the results. I found twisting a square 45 degrees meant the kinematics of the cut were completely different and both x and y axes were being used at the same time for all faces. Be interesting to see your results for that method if you had time.

Hey Marius, I really enjoy your Videos, keep up the good work. I watched your videos on the Hammer tablesaws before i decided to get one, it ties in well with the A3-31 and N4400 i already had. Are you aware if or are able to ask Felder if they are planning on making a larger Hammer CNC, say with a 1200mm x 600mm working area. This current model is a little small for my needs, but tempted to wait if there is something in the works.

I wonder if a dog with a hole through the center, 1/4" or 6mm, slit in the bottom centered going up, then cut an angle on each side in the dogs bottom from the outside to the center to make a wedge fit. 3D print a wedge with a nut insert in the bottom, run a bolt through the center and when the dog is inserted in the hole to the bottom, tighten the bolt with the hold down in place to tighten the wedge and it will hold the dog in place. Adjustment spacers could be used for different wood thicknesses. Just an idea I had while watching. Terrific job on the waste board!

Have you considered the inserts with an hex drive on top? They come in a lot of different lengths and are suited for driving them into wood even better if you ask me, since their outer thread are more coarse (like you would find on a would screw). Besides that, excellent work as always!

Hi Marius What is the feed and speed you run your program on?

6:22 -> depending on your controller adding G64 and a P value of 0.25 or even a bit higher could help. also adjusting the smoothing in CAM might help but I haven´t used vcarve/espire for quite some time and cannot remember if that´s an option. in fusion it would be.

Put a hole in the centre of you dog or a groove down the shaft, it'll let the air through and the won't get stuck in the holes due to the pressure caused py the vacuum created when trying to pull them out 😉

Shortening threaded inserts is much more tricky with a bench grinder. Would that I had a lathe.

I thought that was where he was headed but yeah, seems like it'd be a lot trickier. Maybe with the same setup he showed for how threaded inserts are normally installed (8:45), but with bigger nuts and bolts? That would keep the insert parallel to the grinder table, and thus shorten it while keeping it flat. But then you need a whole separate setup for deburring the threads.

So, I guess you are using the limit/homing switches of the machine. The dog-hole zero positions are then referenced to the machine zero, defined by the homing switches. Because you don't have servo motors, the machine actually won't know where it is when you turn it on and needs the homing switches Is that right?

XY manual alignment = 30 seconds with electronic probe - 100% accuracy. This job looks like 4+hours , so you need some 500 projects to compensate. And the base plate is unmovable which sucks if you need thicker stock or if it gets damaged by water.
