Wow nice plans. I think I'm going to try to duplicate it myself.

Hey! Very well done plans! It's weird.. While wracking my brain trying to figure out how to make cheap, effective slides, I stumbled (by accident) on attaching roller skate bearings to pieces of angle irons, and running them along steel shafting, or better yet, 1/2" metal conduit tucked inside 3/4" PVC pipe, all being supported on bottom by that steel "T" bar,(looks like steel fence posts) on the bed of the mill, or router.

After downloading your plans, lo and behold! There's "my" idea - I swear I had never seen it before yesterday!! Isn't that weird? But man, It works!! Very cool.. Thank you for your hard work and dedication for making the plans!!

(here, I'll put in a cheers smiley for ya! :cheers: )

Hello,

Went to Adobe's web site and downloaded and installed every update I could. Still won't open for me. Any possibility you could e-mail these plans to me? Would really appreciate it.

Question about the use of gas pipe as bearing rails.

Should a person have then turned on a lathe to smooth them out or will plain sanding do the trick?

[cncadmin]

I would think that just sanding it with emory paper would be enough.

Have a question, I am a cabinet maker making this machine and am looking for all new electronics for a good price. Now the thing is I have enlarged this to a cutting area of about 36"x60" and will not be using this for cabinets but to cut foam and 1/4 ply wood. So around what 0z. steppers motors ,ECT. do I need. Any help would be greatly appreciated! thanks in advance. Jason

I have an enlarged version also at 16X36 mostly cutting 1/2" MDF and I am running 116 in/oz motors and they seem to work fine using 3/8-16 threaded rod. I had 80oz/in motors and they worked ok too but never went back to them. Watch the whipping of the lead screw mine at 36" gets kinda scary at anything above 70 ipm when joging.

16x36" ?? Is that not the close to the size in the plans? Where is a good place to buy these steppers and electronics? Thanks

[CNC Darren]

Pretty much the same size but just extended 12".
I'm using the HobbyCNC 3axis chopper driver board.
The 80 oz motors came from HobbyCNC
the 116 oz/in motors came out of a Sharp Copier, the older copiers used them to feed pages on the document feeder on top of the copier there are 2 in each copier. So far i have managed to get 8 of them. My brother works for a Office machine supply company so he lets me know when they get some junckers in off of lease and we go in and strip them. I have several 38v 15amp that came from copiers that work great for cnc also.

Hey Guys,

Thanks for the Plans!!

First post, I'm a friend of Ashers helping him out trying to get this thing together. I,ve been looking at a bunch of different programs and motors to use, and i want some opinions.

Im looking at the 640 oz steppers from homeshopcnc, and was wondering what controller i would need to use on them.

Also any thoughts about deskcnc and deskam?

Were planning on using 1/2 inch acme leadscrews(they will fit in the chuck of my lathe) should we go bigger for the long 60" run? or use dual nuts spread out on the gantry to smooth and quiet things down. Any idea of thread pitch to use with the 640 oz steppers? were looking for 120 or so IPM jog rate.

Ive also been pondering on using timing belts and pulleys between the steppers and screws, is a coarse thread acrew with a geared down stepper better for faster jog and cutting rates, at the expense of a bit of prescision? this way i could also play with gear ratios...

The machine will mostly be used to cut stacks of 1/4 inch foam....

Sorry for so many questions, Ive been reading into the late nights on cnczone for a few weeks now, Some of it is starting to make sense.
Thanks for ANY input..

Not too much activity here...

Turns out Enco only has 1/2" acme in a 10 TPI, would this work?

Im pretty sure the Gecko drives will work with the 640oz motors, any thoughts?

Dylan

[wtxrcdog]

I was also thinking about useing 1/2 -10 acme all thread rods and building a teflon nut for the mooving parts. what do you think about this idea?

[Ferenczyg]

Dylwad, geckos are OK for any stepper below 80V and 7A. Just remember to heatsink them for currents over 3A.
