    Mach3 display settings

    I just moved it to a new computer. The display settings in Windows are correct, but somethings up with Mach3. I can't get it to go full screen, and the aspect ratio is off.

    Thanks!

    Kernal Speed?

    I just upgraded from a maybe 15 year old computer to an Intel Core 2 Quad Q9400, 2.66 GHz, 6 MB L2 Cache, FSB 1333 MHz.
    The Kernal speed is set to 35,000Hz from my old configuration. I'm not sure...

    Tool coatings - AlTiN vs. AlTiNS

    I haven't found the appropriate English translation, but my German supplier sells carbide radius cutters with both labels. The latter refers to sulfur, which they claim is even harder, and costs...

    Re: Breaking Cutters is breaking me

    Right. I meant that I use TICN coated HSS-E ball ends, which seem to cut smoother. I use uncoated carbide straight mills.

    Re: Breaking Cutters is breaking me

    Old thread, but first, how deep are you cutting? Why are you buying stock from HD? You can get better alloys online for cheaper. I would never try to dry-cut 6061 with a high speed spindle. I don't...

    Re: Table Material

    I might try that as time goes on, but I don't think there will be a need. An M6x1 gives me 12 threads. That's a lot. If does degrade, I can just bore out the threaded holes, make some round stock of...

    Re: Table Material

    Finally did it. I decided to go with Corian. I found a slightly scratched piece for about $100, so it was cheap compared to the alternatives I was looking at. It's only 12mm thick, but with the...

    Re: Table Material

    Thanks for the idea, but it sounds like more effort than I need. I am currently just using a plain piece of MDF, and it has worked fine for four years. I just got a sample of a Corian type board...

    All points taken. I think I'm going to go with the Tricoya. I'm guessing it will perform similarly to my current MDF board, but maybe even better, not to mention that I can work wet. MDF has served...

    Re: Table Material

    That sounds good. So far I only find copper clad PC board though. I naturally pre-drill before inserting screws. I'm not that much of a cave man!

    Re: Table Material

    Yes, I suppose I could do it, but it would be slow, and I'd have to tap the holes. I like the quick and dirty method of sinking deck screws in the MDF. Someone suggested Corian?

    Material for CNC router Table

    I have a router with an MDF table, 700x1100x21mm. I mostly dry cut brass, and also wood and machinable aluminum. I would like to have a table which would allow me to cut wet. I could get a slotted...

    Re: Trick I figure out today!

    Yes on both counts. 1. My table is MDF anyway, so no big sad cutting a hole in it. 2. I have so much finishing work in my operation that there isn't normally a queue of jobs waiting to get on the...

    I do plan on grabbing an indexer. A lot of the parts I make would still need the trough approach, though, and it's a gantry router without a terrible amount of Z height.

    Re: Tips for drilling wood?

    I think I just have my rapid feed setting set way too low (27.5ipm) for the Z axis. I'll see how much I can bump it up. I drill sizes from 3 to 6mm, sometimes 25mm deep, using either peck or fast...

    Re: Tips for drilling wood?

    Yes, I don't see a simple solution here. I will see how fast I can run the Z axis - probably faster than I have it set at the moment. Otherwise I don't do that much drilling anyway, so I can simply...

    Ah. I've been using much slower speeds. I don't think my machine will go anywhere that fast, though. Maybe 40 ipm.

    I mostly cut brass, but do some woodworking. Everything is fine except for simple drilling, in which with whatever drill/endmill or settings I try for hardwoods I get burning. MDF isn't as bad. I...

    Re: Setting direction for "Planar"? v.26

    I am choosing a surface for geometry, so I don't see setting a contour as relevant. The toolpath works fine though, even though the start point is reversed for the left and right portions.
