General Mach Discussion / Re: 5 axis

I haven't used it myself (I have a multi-axis seat of Mastercam), but this guy has successfully done so.

First i will try to edit this file and see if it works.
what cam software if suitable for 5 axis?
 

Fusion 360 will generate 5 axis code.

General Mach Discussion / 5 axis control

« on: October 03, 2020, 10:58:52 AM »

If I purchase a license of Mach 3, will it control 5 axis? I've built a small 5 axis machine (just for fun, to see if I could do it), so of course I need a controller.

I presume it is only when doing a move with at least 2 axis that you are seeing that? That is blended speed which is the speed the actual cutter is doing. As an example you are at X0Y0 and you tell the machine to move to X10Y10 the axis will move diagonally and that means the path the cutter takes is longer than the 10 units each axis is moving. As each axis is doing 12IPM then the blended speed will show more.

Ah, that makes sense. Thanks

Motor tuning, your Velocity you have set is your rapid for that axis.
Hood

I've set that to 12 ipm in both the X & Y axes, but (with FRO at 100%) it still moves at a rate over 14 ipm.

Where can I set my maximum Rapid feedrate?

Thanks Hood, I've ordered some ferrite collars & we are going to add some grounding straps. But setting the Debounce to 2000, from 0, seems to have fixed it for us.

General Mach Discussion / Interference issue

    We have an old electric eye tracking, ox-acetylene flame cutting table that we've converted to CNC using Mach3. The machine works fine except when one of the welders strikes an arc & starts welding. It causes Mach3 to display an E-stop or limit switch alarm. As you might imagine this has caused some scrap.
    Does anyone have suggestions on how I might be able to fix this issue?

    Thank you very much Hood, you've been a tremendous help. I had to set the kernel to 75K to get 25 IPM, this should be sufficient for this application, it's an oxy-acetylene cutting machine so fast feeds are not really needed.
    Now I get to play with it a little more

    My reply earlier got lost somehow. Yes the 156386.2959 steps per unit is necessary for this application. The machine I am retrofitting has the steppers attached with 3:1 pulleys to gearboxes driving pinions on racks, for both the X & Y axes.
    How can I increase the kernel?
