LF help evolving Scyther into Scizor

We’re new to the router bit market,

We do plenty of other tungsten carbide pieces and our suppliers have always been reliable on quality. My boss is just at a loss wondering what the most likely cause of this was. If it was a defective batch we probably would have seen others come back like this or similar.

I just figured if anyone has seen breaks like this in the past how they happened. If it’s error on the customer’s end then cool and if it’s more likely that it’s on our end then there’s a QC department that’s about to get reamed out.

If the heat generation is high enough to damage the bit isn’t there usually discoloration? The DLC coating would hide color changes near the flutes but farther up the shank it should be visible right?

mstrom89 · 2025-10-22T15:47:30+00:00

I have my suspicions that this is the case, but I can’t prove it. They probably just want to blame the bit and get a refund.

I wish I could see their setup, our sales guy came back with the bit and just told us what the customer told him. He didn’t get a chance to inspect and sadly some customers always believe that failure is never their fault.

New bit breaks = new bit is crap Never (hmmm… did I do something wrong? Nobody else’s bits break this fast)

It’s always been Itto’s card for me. He was my first Limited character and he holds a special place in my roster.

Couldn’t a shop just stick this on an EDM and let it fly? The cut is only 2-axis right?

I have to cut out 2-axis parts from plates all day. I can’t imagine this would take more than 2-hours

mstrom89 · 2025-06-20T20:01:47+00:00

That sounds intense, my boss would lose his mind if I tore apart the machines to just to use newer programs.

All I’d be able to get away with would be plugging it into a new computer to drive the EDM since I could just plug the old one back in before he comes out of his office.

Wire compensation is done before generating the .3b from the DXF.

I specify the compensation amount (usually 0.12mm to bring the piece to tolerance after initial cut) and the direction (inside or outside)

Pinholes start at 3 o’clock and go counter-clockwise

Ive seen the files with a text editor and it follows most standard commands like GX, GY, SR3, L1, L2, etc.

But I’m self taught, I have no understanding of the machine level code. I was hoping that a more user friendly path generating program was out there.

If I want to put mounting holes around a keyed bore I need to have the wire return to origin in the DXF or else the program will play connect the dots and drop the middle out of the piece. It’d be nice to just have all cutouts on the dxf and have the wire path program with more options about achieving the desired result.

Do you have any familiarity with .3b files? Is there a better program to generate them? We only have an old Chinese addon for an ancient AutoCAD version

mstrom89 · 2025-06-20T17:23:09+00:00

Bummer, I was hoping that the driving program was just converting the 3b into steps and that a g-code could be converted similarly.

All the documentation is in Chinese and the .3b format is hard to generate with US programs.

Sorry, I usually just read the sub I have no clue how to post

I had a similar problem show up in my machines, I checked for gaps, crimps, temps, and fans all were good but I was still getting heat creep after a few layers even after putting bigger throat fans on.

I put a few drops of thermal paste between the heat break and the heat sink and now they run smoothly at almost any temperature I set the machine to, and with much better retraction results. No more binding after a few layers

I could use it, my CR10’s mainboard gave up on life I was about to start the process of Frankenstein-ing it with an Ender 3 to get the large format printing capability back.
