%!$ Easy Diy Woodworking Bench Plans For You #!@

cnc-shark-hd-2 I should try this on a smaller, faster job. The bit went cnc shark hd 2 the material, scratched my table, and the Bit broke. What I can see just from the photos, it looks like you may be losing steps at certain places, and also on some letters the bit was bigger than the opening. This can be corrected by first aligning the z-axis carriage to be perpendicular to the dhark of the machine. Cnc shark hd 2 by KeithW » Mon Dec 07, am.

I then set up the touch plate, and used the shark control panel to detect the touch plate. I then ran the code with out a bit to test it. I then put the bit back in and dectected the touch plate again. The code ran fine with out the bit, then on the second attempt with the bit, it worked fine until part way through. The bit went through the material, scratched my table, and the Bit broke. I am not sure why the machine will not hold The depth that I programmed on the z axis for the entire tap file.

It worked properly for the first time that I did a test run with no bit. Does anyone have any ideas? Thank you in advance for all your help. That will make the controller think the router is higher than it actually is, resulting in the bit going lower after the stop occurs. There will be a stuttering sound when the carriage attempts to go beyond the solid stop. Was the carriage Z0 higher with the bit in when the run failed? That could cause the problem I mentioned above. Note to others: Shark CNCs do not have any program or limit switch limits.

They just hit the frame if you attempt to move too far. Good judgement comes from experience. Experience comes from bad judgement. The machine had run through half of the tap file then started a plung downward. There was no stuttering sound, the bit just started dropping down. I had to hit the e-stop button to make the machine stop before it blew a fuse due to being embedded in the machine.

Can you explain what you mean in the second question? Thank you, Jeanette. So it might have hit an the upper limit during the cut. However, from your description it doesn't sound like that was the problem. If you repeat the cut does the problem repeat?

If not, it is not a G-code problem. I would suggest you contact NWA to see if they have any suggestions. I've not had any problem like that with my Shark. The closest was when I failed to tighten my spiral upcut bit in the chuck adequately, and it pulled itself out far enough to hit the table.

Re: Help with z axis Post by martin54 » Sun May 01, am How thick a bit of material are you trying to cut, I can't help thinking you are trying to lift the z axis to high as Mike has already suggested.

But like I said a little more info would get you a pretty good answer.

Wood is tough on a bit. Unless your buying bits from a quality manufacture, your bits aren't going to last long. Could it be that you are experiencing some distorting of the wood panel during machining? This can be caused by tension released from the wood as you rout one side or working with insufficiently dried wood. The exposed side dries and shrinks causing the panel to warp. This would result in steps showing up between your large tool pass and the small tool finishing pass.

Regardless of what might be causing the depth issues, you can clean up the job by running a clean-up cut full depth using only the small diameter bit slightly deeper than the deepest measured cut on the workpiece.

It will soon hang on our new fence. My wife is from Alabama. The pine Cnc Shark Hd4 Canada was screwed securely to a plywood backer board and had about 8 clamps around the outside, it should not have moved. I added an extra pass than originally computed for each cutter. On the out side ring I used a 0. Inside I used 0. The most expensive ones at the Rockler store near me. All the bits used were brand new and I had a sticker shock at my bill. They still look new and sharp after this one use.

I am curious about rerunning the final tool path. I could reset the zero and run again; or try the Duplicate Toolpath button.?? I should try this on a smaller, faster job. Re: Quality Problems Post by ohiococonut » Mon Dec 07, am The Shark is not known for loosing steps but it is notorious for couplings coming loose. Check them all really good. All being equal, you're right, the piece should not have moved. Either way, it sucks.

Hope you find a solution I don't understand why you are using 4 bits.
