Ideally the computer will set and read the RPMs. For now I can just do the timer thing to get it running and calculate the RPM by hand. Later, I...
Yeah the main thing is the weight of the z-axis assembly+spindle. My assembly is extremely heavy when you add up all the screws, gantry plates,...
OIC now. I am looking at the parts for a PWM controller and it looks like I need the 555, 2 capacitors, 2 resistors, and a potentiometer. Another...
That site always gives me an error going to a url if I'm not logged in to phlatforum.
So let me get this straight... Someone in Hong Kong is willing to sell you something for cheaper than you can make it yourself. They are also...
I don't know if the board can send more power than the motor will use. I guess it depends on the board. Anyway, yeah you need a bunch of different...
So the v-slot in the first parts list is not the same as in the photos of the build of routy. Also, if you do the math you can see the cuts don't...
I've heard of people frying their controller board by rotating the motor really fast. You're probably in that category. I hooked up a 3A motor to...
Hey you could mount the de-mag to your hard drive and hook it up to a mercury switch so when the NSA tries to take your computer it erases the...
I second that. [ATTACH] Now, if we could use our OX builds to machine toothed v-slot wheel and racks, we could all upgrade to rack+pinion for the...
I'm working on building the Pulse Width Modulator (PWM) generator which is required to control an Electronic Speed Controller (ESC) which controls...
I'm planning on doing this with my routy and eventually OX. Instead of ordering extra v-slot for the frame to support an mdf table, I'm making a...
The wheel kits have precision shims. For the spacers used outside the wheel any washer will work but I think the shims and washers are the same...
Good question. Here's why: Since the outer race of the bearing contacts the wheel spacer and the inner race of the bearing contacts the axle...
You could assemble the carriage and then use it to press the belt down while gluing. Just roll it back and forth a few times every couple minutes...
sand some of the delrin off or use a vice to compress the delrin contacting the outer races until the inner races contact the spacer. You may be...
If you don't use a shim your bearings will wear faster. You have a bolt pressing the inner races towards each other and with no spacer/shim they...
My understanding is the precision shims are normally used between the bearings, inside the wheel. The shims on the parts list are the same as the...
How about this?[ATTACH]
Try this for vertical vslot.. [ATTACH]
