Whose Fault Is ThIs?

[AndrewM]

Hi Ray,
Brian is pretty busy these days, but if you send him a reminder email about it every now and then I will also throw reminders his way.

Well....  It no longer affects me.  At the time I was using the knee on my mill as the Z axis.  I've since built a quill drive (and the knee is used only for tool length compensation), so X, Y, and Z now all run with the same velocity and acceleration, so I no longer see this problem.

Regards,
Ray L.

I have a stepper system and I've been dealing with this problem for around 3 years.  Never found a solution.  The only workaround I have found is reducing feedrate to the point where it doesn't lose steps.  In my case, I have all accelerations set equally but the problem is still there.

Would be nice to finally find a solution.  Every other code runs absolutely flawlessly except the cases refered in this topic.

From reading the topic it seems the best work around is Exact Stop.

However, if you email support@machsupport.com so my counter parts and myself see the email I'll see what can be done to get this moving.

[lfleiva]

Thanks, but exact stop mode is not a practical option for the kind of work required; both in work time and finish.  I'll email.

Checking back in to harass ya guys that exact stop is not a solution

In fact helical ramp is critical to speed! I haven't been able to recommend mach to folks because of it.

Basically it kills thread milling, advanced troichiodal milling, cutting out reflectors, etc.

Please fix it as I'm forced to use software that has subpar user interfaces because of it.

Just a note this is fixed in the Dev version..

[yaddatrance]

Wow... Does that mean the one thats currently out?  Mach3 R3.043.058?

If so, you guys are moving to my new happy list.

[Brian Barker]

Yes.. There was some work done to CV.. If the code I worked on didn't fix it please feel free to contact me off list and we will see what we can do to make it right

Odd. I have been using helical cutting and thread milling with CV for ages with the lock-down version. No problems at all.
