I've gathered some 1-1/4inch black iron pipe, and built roller bearings ala JK. I picked up some hammerite paint, about $8.00 in hardware, and Some 1/2 - 10 ACME precision threaded rod from MSCdirect.com. Tomorrow I'm going to Lowes to pickup some MDF. I'm still working out the cut sheet for the wood, adapting from my own needs, and JGRO open source plan.
I'll provide pictures as I start working out fit and finish. I've also obtained one stepper motor from an HP LJII, an Astrosyn 23LM-C701-01, 5.2V, 1.4A. It's a beginning.
I haven't decided whether to bravely buy the hobbycnc board or the Xylotex. Budget is tight, however soldering skills are rusty.....
I'd appreciate any suggestions as I go. I'll post intermediate assembly and designs prior to assembly. Thanks for all of the borrowed ideas, inspiration, and can do attitude, I see from everyone!!

I just finished the Hobby cnc 3 axis chopper board and couldnt belive how easily it went together. I'm not the worlds greatest at soldering but it only took me 1-1/2 hours and the motors were spinning. I got the board/motors combo.

Thanks for the info! I was worried about putting my money into something I wouldn't have the skills to complete. Now, I can save the difference between the zylotex board and the HobbyCNC board, and put that into other parts, or tooling!

Where would you rate your electronic and soldering skill level( 1-10).

A 3 right now. It's been several years since I've done any real soldering. Last time was simple component replacement of a PC board mount power plug.

I finally pulled some time from work and elsewhere, and got some more progress on router project.... Pictures soon to follow. I bought the new three axis 4aupc controller board kit from HobbyCNC. Great kit, great service! Can say enough good things about Dave's services. Picked up an old craftsmen router from the local pawn shop for $20. It'll do for a start... I've built the y and z axis, most of the gantry. The y and z both slide easily, though I still have to get a few coupler parts in to mount the acme leadscrews. Next up is the x axis and setting up the wiring and electrical. Does anyone have the pinout/wiring diagram for the HP Laserjet motors? AstroSyn steppers, unipolar, six wire......

I have the hp lj III motors, and i used the wire color chart that came from hobby cnc when i got the board from dave (easy kit to work with), it is in there exactly what color goes where. Use the Japan servo 6 wire.

Thanks, Joe! I've thus far resisted the urge to spin motors, but the time is fast approaching!!....

Lurch,

Great name. Brings the image of some humped back geezer saying 'You rang' ;)

Anyway looking forward to following your thread. It's good to learn from each other. The resist to spin the motor's kicks in quick so I'll count the posts before you announce you went cold turkey and just had to do it !

Good luck.

Here are a few pictures of the y and z axis thus far. MDF, skate bearings, hammerite black, UHMW block, HP laserjet motors.

I got this either on this site or somewhere else....I appologize for not being able to give whomever posted it the credit...

Thanks for the motor specs! They are a big help. Working on the turbocnc computer build, and install....Pics and specs, soon to come.

Lurch,

Machine build looks great so far! I hope you got some useful information from the HP LaserJet II/III Stepper Motor data sheet I put together. Let me know if there are any changes or information you'd like to add based on your building/interfacing experience.

Currently I'm working on my own machine (weather permitting) but haven't made it as far as you. I'm anxious to hear how the HPLJ-II/III stepper motors perform with the HobbyCNC 4AUPC Chopper Driver Board Kit. Personally, I am leaning towards the 4 Axis Unipolar Drive Kit from Xylotex but haven't comitted one way or the other, yet. I like how the Xylotex board gives you access to all of the parallel port pins through its interface (unlike the HobbyCNC board which seems to drop pins 1, 14, 16 & 17).

Keep up the good work and keep everyone posted on your progress.

Following in your footsteps...

The hp laserjet motors work great i use im my machine i just finished and use a 1 1/2hp router that they push trough wood and mdf with no problems, also have the hibby cnc board running them.

I gave up on getting all of the binding out of my axis after several days worth of work to get them corrected. I have dismantled the current router, and salvaged all hardware. I am already cutting pieces for a smaller cabinet-type router, look for yukonho's thread for a picture. I did get the motors to turn on the old router, though only with everything unhooked mechanically.
I hate to start over at this point, but I have learned alot, and the wife will be happier with the cabinet style contained router unit. I can't wait to get up and running....Will start a new thread with all the details. Thanks guys for all of your support and encouragment.
