Hi Azalin, any progress on this project?
I'm working in a custom cycloidal gear for my project,
I'm studying a lot, the concepts, reading a lot of articles and drawing and drawing for days......
I’m from Brazil,
unfortunately concrete UHPC is something very recent here, extremely expensive and difficult to find, it is not something that I can consider using.
I was talking with a friend...
First, thank you for your participation here, it is very gratifying to be able to learn and discuss these things with more people! :)
about the stiffness tests, I bought some tools...
Nobody?
It seems that the forum was much more active a few years ago
If it weren't for the empty spaces (bubbles) on the surface of test 1, I believe it looks a lot like the result achieved by stef110 on the other topic:...
And now the result of each test, already dry (more than 24 hours later):
TEST 1 - 12% epoxy

Hi all,
It is the first time that I'm working with epoxy granite. Epoxy in my country is something very recent, about 5 years ago it was impossible to find an epoxy with affordable price for a...
Maybe...
I've looked at these images about 100 times lol
sometimes it looks like he machined the tip of the long nuts, maybe to make it less apparent on the granite epoxy surface
look where I...
Thanks maxspongebob! I saw and opened the 3D project , but the insert/plug is just one body, and I didn't understood very well.
Maybe you can help me with that.
He used this nut (example link...
steff110 can you share more details about the thread inserts?
Which parts did you used? I realized that besides the nut, washer and screw there are other parts
really?
I'm no expert in this on the subject, but reading this documentation...
Makes sense,
And about the the torque x rpm,
to reach 6000rpm with a 4pole motor I need to increase the frequency To 100hz (+70% rpm) and use a 2:1 pulley ratio, so my the torque will be 36%...
after your answer i started to research more on the subject, the vast majority of people alert to double the frequency to double the rpm, that there are several risks of damaging the engine, so I was...
I knew it was possible to do this but I wasn't sure if it was a practice used in CNCs
Good to know !
I can buy one WEG AC Induction W22 with 5hp (3.7kw) with 4 poles and 1760 rpm. I intend...
Hi!
I've looked and read several posts here on the forum and elsewhere, but I'm still in doubt about what I should use in my project.
I've had some CNC Routers, all with the famous 2.2kw...
Datron's M8Cube CNC looks very interesting to study. Unfortunately it is difficult to find photos and videos to better understand your design.
I would like to understand what gantry Y looks...
Thanks Al!
I was looking for the latest, I hadn't found this 2007 document! I will start reading
I thought about cutting off the power supply to the drivers / motors, leaving the VFD and the grbl...
I redid my diagram, in your opinion is it correct? I added an e-stop system, the idea is to use the 24v to also power my Inductive Proximity Sensors
Thanks for your reply,
I reviewed my schematic and added fuses in some places, I would like to know what you think, does it make sense? or somewhere has no need?
I will take a look on this...
It is my first time assembling a CNC electronic enclosure, I have some notion of electronic concepts, but I confess that even after reading many threads and sites I still have some questions.
I...
I don't talked yet with the kitchen top supplier or a stonemason, but that is a good idea.
I researched about the granite kitchen, the surface with 15mm and one square meter has 47kg, so my cnc...
Hi,
I am creating a medium sized CNC router, the table will have 1320mm x 1000mm (around 52" x 40"). My machining will be on aluminum and steel parts. I want to use coolant system with great flow....
Thanks Peter!
I will study more about that
I am trying to calculate the nema23 motor needed for my Z axis.
My Z axis with spindle has 22lbs and chinese ball screw SFU1610 (diameter 16mm / pitch (lead) 10mm)
After much searching for...
I don't understand how the othermill power supply have only 4A to power 3 nema 17 and 1 brushless outrunner. Anybody know?
Hi!
I read several topics on how to mount a spindle using brushless outrunner. I know what I need to assemble, but I'd like to know the best options about the brushless motor, ESC and power...
