CNC ROUTER, HOW TO, spindle tramming using a granite surface plate + DTI and skimming the bed flat

[@samusad]

greetings dear Roger. always rich information, watching the video here with my wife, she congratulates you and asks how you manage not to affect your objects on the shelves with dust, since you machine a lot of mdf too.

Tell her that he has his wife dust his shop every day - that'll get a reaction :)

I would have measure each point of the granit slab with the gage fixed relative to the spindle. To be sure that the slab plane was the same as the xy plane of the machine x and y axis. Shim the granit in consequence , then proceed to traming. You did do it on camera but spoke about it in the beginning.

Peter over at CNC Nutz sets his depth of cut at 0 for his bed flattening program. He then zeroes the cutter on the bed and then adds the depth of cut to his zero in Mach 3. That way you can adjust the depth of cut on the fly to get just what you want without changing the program. I tried it and it worked pretty well.

Hi Roger . How about using a quarts bed as bed ? Bolt that down and have 25mm baltic birch on top with screw inserts ?

I'm new to the CNC world, as expected I have two questions 1, I own a iGage dial indicator but trying to figure out how to mount it. Did you make your mount or is bought? 2, trying to decide on the software ither Carveco Maker or Vcarve Pro, any suggestions. Thanks Jon

Hello Mr Roger. Please let me know as I am new to cnc the speed of when you did the surfacing of the bed please. Would greatly help me a lot. Ikr it's an old video but it's very help full. FYi I use a 1/16 skim bit on my diy cnc 1155x1795 bed

Ok, 50mm per sec and 22mm step over with 1mm cut, but that is with a 2.2kw spindle and a 50mm cutter @ 18,000 RPM

You need a longer "arm" to square/tram the spindle properly.

Its good for me

[@giuliobuccini208]

No, no, no. Mr. Roger. you're making the spindle square to the granite slab. But the granite slab could be not parallel to the plane XY created by the mivement on the X and Y machine rails. Please check my method I posted in your previous video.

I dont think so, Its good!
