:cheers: Thanks....I like their aluminum tables too...

I have a quick question on the parts list in the plans, it calls for using:

2 200XL 10 tooth timing pulleys with the bore to match stepper motors shaft and my steppers have .25 inch shafts and I...

I just bought the plans a few days ago and in process of aquiring parts. I will post a build thread when ready to actually start assembling..

Happy Father's Day to all...

Thanks for the QUICK response and sorry I didn't do a better search. (nuts)

Would anyone have a vector graphic of a horse head(s) side profile? It could be of 1 or 2 horses... I just need the heads with mane's. I appreciate it alot!

Thanks for the help, :drowning:

Looking forward to it...let us know when available.

Bob

Looks nice! Good job.

You also have alot of room around it to manuver. I wish I had that space.

Bob

To give you a little more encouragement I used the 5 start screw on my Joe 2006 unit for the X axis and I love it... It moves so smooth and FAST! You won't be disappointed.. I am using the Kelings...

Where can I get it?

Thanks,
Bob

Thanks!

Yes this is a BIG improvement from before. I finally got a house with a garage so I have the room for the larger machine.

Working on the electronics today..will post pictures of that...

Here are pictures of the completed machine. I added 2 pieces of birch plywood on top of the top deck sides to prevent dust from getting on the rails of the X axis. The reason I choose the plywood was...

Nice design Joe!

Can I ask how you managed to connect the pipe/rails for the Y and X to the support pcs? It looks like you have some sort of plastic spacers between the two but how did you...

Thanks Joe!

I got the X axis working last night... what a BIG DIFFERENCE the new leadscrew makes. I am getting 250+ IPM rapids and its so smooth and quiet! There is absolutely no whipping in the...

Same place I got the other one. MSC. It was something like $70 for a 6 foot rod. I am using dumpsterCNC's anti-backlash nuts on it too. I should be able to get it installed tonight when I get home...

Thanks Joe for the tip. I did read that thread and keep up with it. The only problem I have now is that I only filed down the ends of the Y axis rod to fit the bearings and not the whole rod so...

I got the X axis rod on Friday so I was able to work on the machine over the long weekend. I am almost finished and the only things left to do is to sand the X axis pipes (that is the worst part of...

More progress pictures...

Here are some more pics...

I just finished cutting the 1/2"x8 rod to size and filed the ends down so that the bearings would fit. I ordered shaft collars from MSC instead of using DumpsterCNC's threaded ones to hold the...

I was able to get my first machine to cut out the parts accurately by going 20ipm max speed. It took a LONG time to cut out the parts but at least they are done now.

As for the 5 start rod, I...

Here are the pictures of my X axis construction and the Z & Y axis put together. I just got the 1/2"x8 rod today but still waiting on the dumpster nuts to arrive so I can mount the motors.

The...

I decided to order 1/2"x10 (5 start) for the x axis and 1/2"x8 (2 start) for the y. The z I am going to leave the 1/2"x10 (1 start) as is since the speed is adequate already. I am anxious to see what...

I finally got all the parts cut out using my existing machine and began assembling last weekend. The longest part of this build is waiting for paint to dry! :rolleyes:

These are some of the parts...

I used 5 per board.

Thank Kruetz... although I understand most electronic theories and equations you lost me with that one. Let's say I have a servo motor that is rated at 15amps max... what would the setting be if you...

On the circuit board there is a 5k trimmer resistor, what is its purpose and what should it be set to? I looked through this whole thread trying to find information on it and can't seem to find any....

I have a question on the 1/2" x 8 rods. If it is 2 start then how many turns per inch is it when calculating steps for Mach setup? Is it 4 per inch since there are 2 starts or does that not matter?
...

I bought 3 bare boards from Kin at embeddedtronics.com a while back and finally got around to building them. They work great! Nice and smooth opertation from my test servos and can't wait to get them...

I am in the process of designing one myself and plan to make it 30" to 36" wide also. I built the one from Shopnotes magazine but it was only 24" or so wide and that wasn't good enough for glue up...

For those upgrading to 1/2"-8 rods what is the main purpose for this? speed? What is your expected ipm that you wish to cut at? What type of material are you usually cutting?

Thanks,
Bob
