General Mach Discussion / Re: Problems threading on the lathe

Peter:

 My appologies, I think I may have found the problem, I had forgotten your machien was the fast one that overwrote the neg bit in the timer.
I found the correction had to be fixed up for that as well. It may explain the pitch error. Try this version and let us know what happens.

Hi Peter:

  Hmm. Ill check this out. What was the G76 line you used. That pitch seems strange.. cant figure what its related to.

Better yet, can you try 600rpm again, and then p[ost whats in the lasterrors.txt file.. Itll tell us why the pitch was wrong..

Jeff:

Depending on the 3d file you may need to up the lookahead to 50 or so, and perhaps raise the jerk quite a bit.

Peter:

 What happens if you do a S1000, then an M3 on two separate entries?

Hi Peter:

  The new code makes the thread diags bad.. Id delete them. The version is correct..I just didnt update it.

Hi Peter:

     Actually, I was wondering if the rpm was OK on any machien but mine.

This is hard to test here as my RPMis fine and I suspect its computer mothervaord related.

Here is a version of .32 that has a unsigned interger fix.. Can anyone confirm if this helps or not?

Thx

Hi Guys:

 In theory the spindle timing is done in 64 bit, while I only used 32 bits of it. If you have a vcery fast cpu, it may cause a rollover. Im checking it out now. Can anyone confirm, as on my machine, the RPM reads OK?

Rich:

 Problems noted.

  Ill discuss with Brian an easier way to turn on the G76 diags .. must be an easier way than what we use.

Johns machien reports a bit of RPM sensitivity, threads OK, but slightly different at different RPM's.. He suspects its the machine,
Im tempted to agree, but over time more info will come in.

Thx
