Re: [Emc-users] fun with logging - mach4 edition

2015-06-22 Thread Dave Cole
You certainly got Brian's attention!

Hmmm... no mention of the motion pauses...  only accel violations.

He is aware that LinuxCNC is open source software right?  ;-)
He would be way, way ahead to reuse some of the LinuxCNC code which can 
be done in a legal way and make that plug into Mach4.
There has been discussions of a pluggable trajectory planner for a 
long time.   I think that is also on the Machinekit TODO list.

Siemens is using loads of GPLed software in their proprietary 
software/hardware products now.Every time I buy a Siemens 
software/hardware package I get a little CD that has the
source code on it for the included GPLed software.

 I don't try and stay on top of what is going on in the Mach3/4 world.

 Sam did a bunch of testing of Mach3's trajectory planner testing
 previously, so I think his results of the Mach4 testing is very interesting.

 It's very cool that LinuxCNC has the ability to observe the performance
 of Mach3/4 by interconnecting the two systems.

 That should be a real eye opener for the Mach4 gang.

There's not a way to limit what values are accepted by G-code S-word 
commands.

You could make a small HAL circuit that prevents commands from being 
sent to the VFD is the commanded speed is too low.  Something like this 
logic maybe:

vfd.enable = motion.spindle-on  (motion.spindle-speed-out  275)

Which VFD? The ones I use have many settings, and adjusting the speed

have all of the coil end connections in the 5 pin DIN plug  and I can

Unless they glued those DIN connectors together or they are molded on,  
that should not be a difficult modification.I don't have the machine 
as this is for my nephew.   The machine is about 10 years old.   Any

Yes, you can cut the center taps free of each other
and drive it full coil. You might also consider using
half coil depending on how the motor responds.

All the ones that I have seen are standard connectors
that were hand soldered. Easily modified.

 and drive it full coil. You might also consider using
 half coil depending on how the motor responds.

 All the ones that I have seen are standard connectors
 that were hand soldered. Easily modified.

 Hi Steve,

 I did not know that.   Thanks for the info.So if I cut the center
 taps loose from pin 5 and insulate the individual center taps
 I should
 have all of the coil end connections in the 5 pin DIN plug  and I can
 drive with with a standard bipolar driver?

 Unless they glued those DIN connectors together or they are
 molded on,
 that should not be a difficult modification.I don't have
 the machine
 as this is for my nephew.   The machine is about 10 years old.   Any
 idea if they were molding on the DIN connectors back then?

 Thanks,

 Dave

 Are you aware that the original motors are 6 wire unipolar
 motors with the center taps connected together at the 5 pin

 driver, rewiring will be necessary.

 Is anyone on the list using some of the TB6600 stepper
 motor drivers
 that are listed on Ebay?

 There are some 5A, 50 volt units that are selling for less
 than $15 each
 with free shipping from China or Hong Kong.

 I need to put together an inexpensive control box for a
 Sherline. The
 original control box was lost.

Re: [Emc-users] fun with logging - mach4 edition

2015-06-22 Thread Dave Cole
I was referring to Peter Homann, who first made the comment.He is 
well connected to the Mach3/4 world.
I don't try and stay on top of what is going on in the Mach3/4 world.

Sam did a bunch of testing of Mach3's trajectory planner testing 
previously, so I think his results of the Mach4 testing is very interesting.

It's very cool that LinuxCNC has the ability to observe the performance 
of Mach3/4 by interconnecting the two systems.

That should be a real eye opener for the Mach4 gang.
