Mach4 General Discussion / Re: Mach 4 with ess surging issue

« on: April 26, 2018, 06:07:33 AM »

Your image of the G-code on screen starts at line 767, so line 758 is not visible.

It would be much better to post a link to the actual G-code so others could
try running it.

Mach4 General Discussion / Re: Mach4 is it single pulse threading like mach3

« on: April 14, 2018, 02:07:58 PM »

Mach4 threading is dependent on the motion controller used. Support is possible for
single pulse, multi-pulse (tachometer) with index, and full encoder with index. PMDX
SmartBOB motion controllers support all these modes.

Do you have a signal configured to control the relay?

In Mach4 you would use Config > Mach at the top of the main screen and
then select Output Signals. In the chart there you need to scroll down to
find the signal named Spindle On and assign the UCC device and the pin
number for the relay driver in the G540.

One tool that helps with creating GUI objects for wxWidgets is DialogBlocks.

Mach4 General Discussion / Re: G-code or button for setting radius/diameter mode?

« on: March 10, 2018, 09:34:02 AM »

The lathe radius and diameter modes are two different trajectory planner modes
that are selected on the general config setup page. There are many complications
to doing the correct compensation. Currently there is no other way to select these
modes and I doubt that there will be. Maybe it would be possible to modify a
screen set and scripts to hide the conversions needed from the user in just the
case of tool setting while in diameter mode.

You have asked our question in the Mach4 section of the forum, but the answer
for Mach3 is the same as for Mach4. The thread tracking is accomplished by
controlling the Z axis travel rate, not by altering the spindle speed. Feedback
from the spindle speed sensor is used by Mach to calculate the needed travel
rate to make the threads and adapts within reason if the spindle speed changes
while cutting.

The typical Mach3 setup cannot use a true encoder, and instead uses a single
pulse per revolution to measure the spindle speed. Many encoders have an
"index" pulse which can be used for this purpose.

Mach4 General Discussion / Re: PMDX411 Spindle & MaCH4 Speed control

I think we have found Joe's problem.

His PMDX-411's spindle speed signal was configured for Pulse Frequency mode
whereas the G540 requires PWM mode.

Mach4 General Discussion / Re: Windows 10 Closing Mach4

Check to see if Mach4 still recognizes your license as valid. There is a
chance that something happened to change your PCID. The result
would be that Mach4 would run in Demo mode which will shut down
after a few minutes.

Mach4 General Discussion / Re: Home Signal

« on: February 21, 2018, 09:31:17 AM »

If you have enough inputs you could feed the same signal to two inputs,
one for Home and one for Index. The switch would only kill the one for
Home.

Mach4 General Discussion / Re: Home Signal

Everyone seems hell bent on solving this issue in software, while a very
simple hardware solution exists.

Since the operator has to stop to slip a timing belt on or off when changing
modes, it should be easy to have a switch in series with the offending home
signal from the sensor and using that the operator could use that to block the
signal so it would not fill the logs. You could even automate it by using the
RUN signal for the spindle to control a relay that switched the signal.
