Still you can’t really 50mm deep on a flat wall.The collet will hit after about 30mm. But I don’t know anyone that has done more than about 10mm in aluminum, that is tough.
The lowrider can be as tall as you need it to be, same rules apply to both, a drop table is a good solution as well on either machine. Either one you make you want to have…[Read more]

No freaking way, that is a bummer, I have no idea how you caught that I would have chased that for a long time I am sure.
Dude, if I would have spotted that I would have felt like a super hero, “Detail Man”. I went back and looked, Jan please tell me it was on the one motor we couldn’t see in the pics closest to the wall?
I can not think of a way it could do that other than CAM. If you cut the outside of one then the inside, then moved to the next it doesn’t make sense to be a machine issue. The outsides seem to be aligned correctly.
How fast and deep were you cutting with what diameter, and how long is your Z axis?
I could always use an easier material but with that comes loss of structural integrity and/or increased size.
On the casting idea, there were two possibilities. First, if I can make a casting good enough that it would only require a bit of cleaning up to remove the leftovers from the gating system and taper, then I would only need to mill 50mm…[Read more]
I put 3 jumpers and 32 steps..
I executed the command
G1 E1.0 F30
G1 E2.0 F30
It executes commands slowly but do not match

I can only guess, that the fact of 2 different pullies on one axis produced this effect.
Or I fixed something by mistake without paying attention …
Either way, working like a charm now and I am currently starting to get a grip on Estlcam and am reading lots and lots about the basics of cutting/milling.
Since the only possible spindle is a…[Read more]
I don’t know specifically about the camera stuff. But w.r.t unattended pi, I think making the SD card RO is really good. Use a thumb drive or a ram disk if you need temporary storage.
I also have used the watchdog before, to reset the pi if it couldn’t connect to the internet. It was just because the wifi wouldn’t reconnect automatically if it…[Read more]
I doubt it. But that’s odd. Try it at 30mm. If it’s down to 0.5mm error from 1mm then it’s linear, and wouldn’t have that big of an effect on the washers.
But the machine should move 60mm with less than 0.1mm error. See if you can measure the movements without cutting anything. If it’s not right on by the tape measure, then something is wrong…[Read more]
I am considering using a raspberry pi for weather underground webcam. Does anyone have some suggestions for the best way to do this? WU only uses single images, so I do not need video although it might be nice to have live video. I am thinking of pointing it at the bird feeder also, so my brother a state away can see what kind of birds we ha…[Read more]

Now that I’m thinking about it. That alone would just make the end with the 20T skewed wider. I don’t think that was the only problem. Specifically, in the first pic, the cross at the top is straight, but each side is offset. Maybe it was binding. I think it should look like a perspective drawing, with everything closer to the 20T just bigger.…[Read more]
While trying to cut some washers the centre hole seems to be shifted to the right and maybe a bit up. Hope the picture explains what I mean.
I drilled some marker holes in my bed at 60cm from zero and measured with a measuring tape. The Y axis seemed ok, but the X was 1mm less than 60cm. Would this cause this misalignment of ho…[Read more]

Oh wow. Good catch. Wow.
Ryan, why didn’t you see that in the machine pics?
Now I’m wondering if it would make some kind of neat art if you were to install a 20t on purpose. I bet a line art portrait would look kind of cool…
