I have no idea why your axis not running. I have no experience with those servos unfortunately.

Hi OlfCNC, appreciate the hotkey guidance.

When I click on one of the jog buttons on the screen, the page behind it changes color, turning gray.
Don't know if that means something.

To get around this adhesives are now used in joints to improve the connection grip vs friction eg loctite or epoxy.

Hey Peter. I think adhesives is a great idea, thank you. Particularly considering that the finish on my parts is certainly nowhere even close to the level of perfection that you are used to.

I NEED HELP!

All axes individually work fine when connected to
ClearPath software but nothing moves with UCCNC.

Have been combing through the manuals for
CNC4PC's C11G BoB, UCCNC and UC100 all weekend.

UC100 and C11G powered on.:

Check that you are in the right mode in the ClearPath software Position mode

Check that you don't have the override checked in there software, this needs to be unchecked

The motors should be locked when you power up if not they are not getting the signal / power to turn on

You can check the output of the Breakout Board with a meter to see if you are outputting a signal when you make a move or jog an axes

You know it all works because you ran with the Clearpath software. Its just getting the UCCNC controller to output the step and direction commands correctly. Its got to be something simple. In Mach3/4 the configuration of the Ports and Pins is very important to get right, what you need is someone else's set up file to look at, because those should be more or less standard. Getting the steps right is more of calibration process. You just need to see it run.

BTW I purchased a low cost, about $120 or less hand held oscilloscope. I had to relearn how to use it from maybe 40 years ago but it really helped a lot.

Thanks Mactec54, will do.

I am confused. Is the ClearPath software still active when I run UCCNC?

I thought you run the ClearPath software just to create a motor profile?

[davida1234]

Thank you wmgeorge, I hope it is something simple; just a 'duh' thing.

Override in ClearPath software is OFF:
Attachment 416042

The motors are locked up.

Attachment 416042

The motors are locked up.

That's good looking at what you just posted they are off as well so that part should be all good

The Breakout Board has red lights they need to be green for operational

Do you have the 5v board power correctly connected

Do you have the EStop connected

There was one trace wrong on the wing
pcb boards. Made a new board.

The machine is jogging!

Also, the inside adjustment screws for
the nut retainer were difficult to adjust:

I will be cutting new revised mounting
plates and ball nut retainers for the machine.

Should be ready in a few days.

Thanks for posting. I was missing my David A's thread fix.

[davida1234]

You're too kind...

[Outlawtaz]

Thanks for posting. I was missing my David A's thread fix.

Me too. Can't wait to see a final product!!

[davida1234]

[davida1234]

Finally got to start with cutting the new
servo mounts and associated parts.
Should be ready soon for replacement:

As mentioned, the machine is a prototype for trying out
different designs and revising/improving as necessary.

Among the many inputs submitted here, two kept me
thinking in particular.

One was MacTec54's suggestion of a different approach
for the ball nut retainer installation. He was kind enough to
provide me with sample designs for alternate layouts of the
retainer. The new layout is integrating some of his suggestions.

The other comment came from Ger21 about possible whipping
of ball screws even if they are fixed. Although my screws do
not whip, I thought I might try to consider this while redesigning.

The new layout required recutting of 17 new pieces:

I was also finally able to locate sealed
angular contact bearings in my size:

I did not take any notice of the comment of screw whip,The only way you could have screw movement is if the screw was bent and even then it can't whip, the reason the screw can't whip is the linear Rail would also have to whip / move as well which is imposable for that to happen, the linear rail is fixed and you Ball Nut is guided by the linear rail

That's true and logical and my screws don't whip at
all as you can see in the videos.

However, he did mention it in the thread and after
thinking about it, it could be possible that the screw
might exhibit harmonic oscillations at the long side.

This is a 2x3 and I want to be able to expand this to at
least a 4x4 and I wanted to have a solution for that.
