Spindle Direction control with the Spinx1

10 Mar 2017 23:29 - 11 Mar 2017 12:44 #89383 by comjon
Would like to add direction control to my Spinx1. If I am correct, I need to wire in Pins 9 and 10 to parallel port pins set to output.

My mill has a Minarik 32001A as part of voltage regulation. The rheostat has been removed from the original LightMachine rig, which had only CW turn. I am guessing I am going to need to do some modification to the Minarik wiring.

Yes, Google is my friend too (on most days) :)

Many of the results returned from Google are my prior LinuxCNC entries.

IANAEE nor even close to an electrical technologies guy. If I smoke either my Minarik 23001 or Spinx1, it's a major bummer to replace, given the age of the Minarik board.

There are a lot of these machines kicking around to be put to good use, and I posted both my hal and ini files for the Spinx1 to Minarik for others to use. The tech center up the road has two of these rigs, sitting idle.

I know this is not a glamorous topic for this forum when compared to a mammoth gantry retro or a exotic topics like path pilot. The technical training center where I live teaches Mastercam and Haas, and my argument with facility Director centers on what students are to do when they finish their certificate or degree, take a job in an area other than CNC to pay their bills or end up in a shop with different technology. LinuxCNC, FreeCAD and a Sherline Spectralight offer an inexpensive, in depth, fundamental CNC learning experience with GCode, HalTcl, (Python anyone?) at pennies on the dollar compared to a Mastercam seat license.

The region in which I live is struggling to find talent, and the pipeline for PLC and manufacturing programmers is constricted by a combination of lack of existing (although slowly improving) education infrastructure and <rant> the banking mentality oozing it's disgusting slimy fingers to the outward semi-rural regions as their gift of consumerism to the unwashed masses</end rant>

I have this crazy idea to make training more accessible to students, helping build local talent.

Any comments and shared knowledge on this topic are welcome.

Sounds like you live in my country! Where are you?
I am in Kosovo, strugle with plenty of problems on daily basis.

The U.S.

My wife was in Kosovo a few years back when the flooding unearthed all those mines. Said she was entranced by the beauty of the country.

I was thrilled to learn this week of the release of the BeagleBone Blue. Another step towards open source independence.

I am breaking apart my mill to fix the y axis. Will get back on this topic later.

Take care.
