General Mach Discussion / 555 Timer index pulse widening

« on: August 25, 2009, 07:04:06 PM »

Hi, Jim

On My Compact 5 Lathe the index disk is about 4.5" in Dia. with about a 5/8 " slot to allow Mach to have time to see the opto Puls.

You may be able to use your Index pulse output as it is and add a IC555 Timer to reset with a adjustable time delay, R1 Var. resistor.

Edit: the resistor value is 1K and cap is 0.1 uf. This seemed to be the best values.

LazyCam (Beta) / Re: Problem generating g-code

Hi, Barry

Setup Mach as in the pic below, That should lose the crop cir's.

LazyCam Turn, Load dxf then Clean, Optomize and drag the Bull's eye back to the right end of cut, Set the Tool as pic 2 and set to all layers button, Then post Code, That should get you a single pass.

Pic 3 shows the Load Tolerance I used for your dxf and a G code file from LazyCam.

If you need more final passes, You'll need to insure the direction arrow's are set properly and play with it some more.

Hope this helps, Chip

Hi, Alex

Been a little tied up hear, I haven't used the posting code much in bobcad 23, I think it's just leaving off the return for X in the Post.

Look at this G code and post an example of your G code & dxf.

Hi, Cartierusm

Changing it on your own is fine, Sherline 1/2 Step Mode just set's pulse width's to 40 ms, I did notice that your step & dir Pulses were set low, dir being  set at "0" in motor tuning.

I'm  PM messaging you my phone #, If you'd like to talk about this problem.

Hi, Cartierusm

Try setting Sherline 1/2 Step Mode in ports & pins, or this xml below and see if it helps, It's one you posted on your 4 th axis topic eariller, Let us know, It should give your cont board's have a little more time to see Mach3's pulses.

What axis controls are your using.
