Jsheerin, thanks for the info. I didn't know that is what they were called.

Fortunately, the new power supply I bought from keling has a built in bleeder resistor in it. After about 10 seconds...

Significant progress:

1) Used additional bridge rectifier, and used two of the high rated diodes to drop the voltage. Due to supply variability, or reconfiguration of the wires, the voltage...

Yes, I'm impressed that you surmised that, I have been getting that feeling @ work. When I started this project I was in school I was a niave engineering student and had very little money to dedicate...

Harryn, I'm glad to hear it, i'll make sure to keep it interesting :D

Thanks for the transformer idea, that would indeed be the best way. I'll take a hard look at it to see if I can do that.

To...

Paul, that is very helpful!

I've only been working on the PS by itself, haven't started rewiring the motors to DB9 yet. (reconfiguring the transformer for 50VDC instead of the previous 24VDC)
...

Thanks for the feedback Paul!

I checked in with a buddy of mine who is better at this sort of thing, he recommended I use a bridge rectifier diode in order to drop the voltage. I found the...

Things to do this weekend:

- Rewire my homemade powersupply from 24VDC to 50 VDC.
- Resolder motors to a DB9 connector so I can use the gecko G540 I just received.

It's been awhile since I've worked on this machine, AND documented it. I have made some progress on it since I last posted. I came up with a temporary dust containment box for the table, and actually...

Here is a status update.

I'm still contemplating the way cover/bellows to protect the ballscrews and rails from chips. I've started folding that plastic, but it...

damir_cro, thank you for looking into this. Part of my issue is my point cloud data has dirty info. (ie: 0 length line segments.)

I ended up writing a macro to do weldments in a series of 12...

I was unable to add any additional groups, it simply would not let me select any beyond the first 11-13 segments. Hard corner segments would be preferable, but if nothing else a fluid line would...

I am trying to model a length of pipe from a 3Dsketch with many line segments. The whole 3D Sketch is very long (upwards of 3000 ft.) It has a series of bends and minor changes in angle periodically....

Indeed there is!

What is the course title of a "Solidworks Approved Course for FEA?"

I have taken a term long finite element analysis course for my undergrad where we did hand calcs for with...

I just got my BS in mechanical engineering and absolutely love working with solidworks. I'm working an internship with solidworks and have had the priveladge of using some of the add-on packages....

So I've finished attaching the table to the saddle plate. I've countersunk, all the bolts with .25" of clearance to the top of the table. I measured with the spindle, and I need to level the table by...

This is just an educated guess, but I'd say that switching the PS to 230 causes the transformer to function at a different ratio. 230v : 48 vdc compared to 120 : vdc. This might have changed the...

I'd recommend looking into arduino control boards. They are open source, low cost, and can be used with relays, steppers/servos. You could probably incorporate a pedal for the welder too.

I'm exploring the free, and trial versions of some software first as time permits. (work a standard 40.) I feel really good about ArtCAM for my signmaking, and artsy type plaques.

As for 3D part...

First, let me say I am not an expert. But I do have some ideas how you can speed up your machine.

- raise the dv voltage (so long as it is allowable for your control board. ) I believe the...

About linearmotionbearing ballscrews
So while browsing 5bears website again, i stumbled on this page: 5 Bears - Y axis ballscrew

This cleared up quite a bit about the ballscrew assembly. I took...

I am looking for a quality 3D CAM software package for under $300 USD. I am using mach3, and solidworks. I am proficient in solidworks.

I was spoiled because my school taught me FeatureCAM, and...

Well after fumbling around I returned the 3-way switch and bought a single pole switch and wired up my spindle motor to work with the switch. Next time i'll buy the housing that allows for a screw to...

Couplers
The lovejoy couplers arrived. (Picture attached) The 0.3125 couplers don't fit on the ballscrew shaft. Measured with the calipers I believe something is "egg-shaped" or close to within a...

Purchased the following via amazon:

Lovejoy Size L050 Solid Type Rubber Jaw Coupling Elastomer
Lovejoy Size L050 Jaw Coupling Hub With 5/16" Bore
Lovejoy Size L050 Jaw Coupling Hub With 1/4"...

You were spot on with this. I loosened the motor mount and the noise disappeared. I disconnected a motor and turned both shafts, noise was gone in both. It's not a carriage/nut alignment issue, Yay!...

The video goes in great detail of what was done. @ 5:00 minutes is where I show my most recent issue. Any ideas?

Don't have a lot of time, start work early. Quick post.

I labeled the pictures with descriptions, so hopefully that should be enough. This was work I did over the weekend. Most importantly was...

I am thrilled! It was something simple.... I can't crimp wires to save my life :D



Here are the results after i fixed it!

Progress update
I've found a pair of pliers with the 90' in the end. That did the trick for such small snap rings. I finished the Y-axis saddle plate. And now have configured all three...
