That's good news.
Thanks, Dave

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.

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 co
Are you aware that the original motors are 6 wire unipolar
motors with the center taps connected together at the 5 pin
DIN plug? While these motors can be used with a bipolar
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

I am testing a wizard that Robert Adams is doing for threading with
Linuxcnc. There are problems with the Gcode but I am not clued up enough
to help. Below is the code that is generated but it does not execute. It
runs to G76 and then it just waits there.
I think the I and K values are swapped a

Which VFD? The ones I use have many settings, and adjusting the speed
range and acceleration up to speed are all part of them.

Look to see if the VFD has a minimum speed command setting.

I am controlling a spindle motor with a VFD commanded by modbus. My current
speed range is 0-3500 rpm. If I run the spindle below 275 rpm the current
spikes and triggers the VFD’s protection shutoff. How do I set the minimum
spindle speed so that the user can’t command a speed below 275rpm?

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.

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 testin
