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. Steve Stallings > -Original Message-

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. Steve Stallings > -Original Message- > From: Dave Cole [mailto:linuxcncro...

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 cont

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

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. Ther
