General Mach Discussion / home x homes all axis'

« on: July 07, 2017, 12:45:01 PM »

Hi,

I had my machine working just fine.

I created a button that said "home x" and it would home x

Now when I press the same button, it homes all axis' as if I hit "ref home"

Any ideas?

Thanks
Ben

General Mach Discussion / lost when it comes to nesting

« on: April 28, 2009, 12:30:20 PM »

So I am trying to figure out how to nest. I just want to replicate circles in my y axis, lets say 5 times. I have broken out a text book and read some posts here, but I can't get anything to work. I tried adding L5 in the M98 line to repeat the subprogram but I don't know how to have the subprogram jump a few inches each time it is run. I guess I am supposed to add a Y 5. to add 5 inches each time, but I don't really have a clue.
Thanks
Ben

General Mach Discussion / should all of my axis have the same accel. and velocities?

« on: April 02, 2009, 05:06:43 PM »

I built my machine and it is working great, but I am just always trying to improve it.
Should all of my motors/axis use the same accel. and vel. or will Mach3 compensate for the differences?

It seems when I increase the percent function on the mach screen, my corners start to round...

Thanks

Forum suggestions and report forum problems. / skipped steps with anything better than 1/2 step

« on: June 09, 2008, 11:55:29 AM »

I have built my own machine for woodworking purposes. I have 2 motors which drives my y-axis, which develops missed steps. I was using 1/8 steps, but after 120 seconds, it would start to miss steps every 10 seconds. I dropped the steps down to 1/2 steps and all is well. I suppose I can get by with this, but at slow speeds, it just doesn't sound nice and is slightly jerky, which may not be noticeable for woodworking...
I am running these motors in parallel, 640 oz-in., direct drive rack and pinion. The breakout board is a 4-axis board, which the co. that built it no longer exists (Awesome!).
My other 2 axis are flawless.
I would like to incorporate a gear reduction system for the y-axis, but it seems quite pricey.

Any ideas?
