Did I miss something? Dyes and supplies? 4 colors? Perhaps you're in the wrong thread?
I've been using the anti-backlash nuts from Dumpstercnc with very good results. For motor adapters however, I strongly prefer the flexible...
I saw Sgspencely's questions about my leadscrew retrofit. Yes, I do have lock collars in strategic locations on the leadscrews to prohibit...
No problem, and good question. There are two single-line emitters mounted at approximately 90 degrees separation around the spindle center. The...
I'm not familiar with the bicycle lasers, not really sure what they're for, except to draw someone's attention. I wouldn't look directly into the...
Thanks. It was a pretty easy update, good for basic alignment of the workpiece. Came in handy immediately. Lines are a bit wide but good for...
Very true. My admittedly hobby-strength machine has an operating range of 2x3 feet, for which the 1/2" acmes are ok. This is one reason I love...
Thanks Tweakie! Here's a photo of the "new" z-axis, now with a laser crosshair: [ATTACH] Notice my very high tech Altoids can for the LED...
Didn't think of spring loading, makes perfect sense. More than one way to skin a cat :thumbsup:
VERY nice build progress, I'm interested to see how the long racks and pinions work out in real usage. In my Frog cnc router I undertook to...
Z-Axis now leadscrew, please see YouTube video at: [MEDIA] Enjoy!
Starting the next aspect of this project, converting the z-axis to leadscrew as well. Will post photos soon as the project progresses. I'm also...
Not sure which parts are "wiggly", but I used standard modular RJ45 connectors which are gold plated and have spring loaded contacts. I've found...
Hi Justin and thanks. I used 8-wire ethernet cable (24awg), with four pairs of two wires each doubled for increased current capacity. Never had...
Here's some photos of the leadscrew refit. It also updates various other aspects, such as the dust boot, vacuum table, cable runs and etc. The...
<updated>Thanks Steve, and you're right of course! I've been waffling on this a bit, but have settled on 5-start parts (instead of 2-start) from...
Thanks for the suggestion Paul. While I agree that a double belted drive will be twice as stiff, I want something even better than that. I'm now...
OK, now to get serious. Yes, the side rails are deflecting, but that is swamped by the HUGE amount of belt stretching. As I mentioned in the...
I have found that a LOT of the deflection is due to inadequate support of the long side rails. I'm adding additional angle brackets along the...
The new wheels are available from the OpenBuilds store. I haven't ordered any yet, but plan to. Sorry I don't have a parts list, but I believe...
