Welcome to the SeeMeCNC Community

The G540 is a fantastic unit! I use 2 of them on machines I've converted (an X2 mill and a lathe). I wanted to try the low cost option for the H-1 though "just because"!

They are standard skate bearings that you can get at a sporting goods shop locally. x x 22 x 7. Here's a link to the options at Boca Bearing. The cheap ones, 8 for $7.99 are more than enough for this application. I use Boca a lot for bearings, their shipping is always reasonable.

Dave, what are you using for the heating element?

Well, I'm doing exactly that - or at least a recommendation - with the manuals I'm writing. The electronics manual will have more recommendations since no wire, connectors, etc is included with the kit. But this would be a great topic for input into that. Also for input into the operations manual. C...

Has anyone tried using a single resistor in the hot end? Seems that some of the RepRap type of hot-ends ( J Head for instance) use a single resistor. I wonder if that would help moderate the temperature fluctuations of the head a little since there would not be so much power being pumped in so quick...

Ok, great! I'll have to remember to post JPGs. I don't know why that image was a tif format!

After grappling with the 3 Axis Board/EasyStepper for too long, I decided to try one of the Chinese 4 Axis boards. It came in on Friday and I spent some time doing the conversion. I now have lots of torque on my extruder (A axis). I did have to perform the "opto isolator-ectomy with staple jump...

Thanks guys, I updated the link. The original was a tif image and I changed it to a jpg version. It is possible that some browsers may not show tifs? Let me know if you see it now. Make sure to do a page refresh to force it to reload.

Not sure why Lee, I see it and it is coming from a public server. Sometimes firewalls filter images from posts. What do you see?

Well, let's check that out then. Hello!

Don't be too sure about that Dave! Just kidding, welcome aboard.

Gee, now I feel left out - I have no idea what # my H-1 is. But, it will always be #1 to me!

I keep an album of my machining and other exploits with lots of photos and comments. The album dedicated to my H-1 us located here: SeeMeCHC H-1 3D Printer.

Here is the 1st full print I made back on 3/8/2012: [img]http://mhackney.zenfolio.com/img/s3/v39/p944544228-4.jpg[/img] It was a little ugly because I was experiencing a few problems: 1) I had not made the mods to the 3 Axis Board: removing the 2 diodes and jumping the opto isolators. That introduce...

I get to kick-off with the inaugural "build thread"! I'll use this thread to post my machine and mods I've made.

Hey guys, thanks for creating the forum! Looks great. I am definitely a "forum type" of person! I am going to start a build thread for my machine. EDIT: I forgot to mention: I wrote the H-1 Assembly Manual! And, I am working on the H-1 Electronics Manual and H-1 Operations Manual. cheers, ...
