I'm planing to make a desktop cnc machine for myself as a hobbyist. I'm very much interested in learning CAM softwares like fusion / freecad. I tried watching YouTube videos. I'm looking for experts opinion for best resources to do that. I need structure learning. Please share your insights folks.

Hola, buenas tardes. Estoy interesado en conseguir una versión Demo del programa Bsolid (B_Solid) de la empresa Biesse. Es para instalarla en un PC. Es para mi formación, para aprender a utilizar ese software. ¿Tienes una versión demo de BSolid? ¿Podrías proporcionarme una copia? He intentado que me la proporción Biesse pero no me hacen caso. Gracias

I bought a Stuart Model Planer casting kit a few years back and I’m just starting to model everything in CATIA and will eventually make an assembly to make sure everything fits up correctly and make changes if need be. I would like to 3d scan the castings to make a more detailed model and see exactly how much material I have to work with before I program it, because some of the notes on the drawing say “skim cut”. I’ve seen some apps for the iPhone, but don’t know how well they actually work. Any cheap suggestions besides using calipers?

"I am attempting to cut a 15.5mm deep pocket on a 20mm thick Beech wood plank. I've thoroughly verified that the wood plank is perfectly flat, and I've confirmed multiple times that both the tool zero and the actual zero are set correctly. My configuration is as attached. However, the final depth consistently ends up more than 15.5mm. What could be causing this discrepancy?"

Adding more details, according to my Aspire settings, I have configured 3 passes for the cut. The issue occurs in all three passes. From the very first pass, the machine cuts deeper than the specified value, and this continues with each subsequent pass.

I have a coffee machine that I love but unfortunately some of the parts are made of black plastic including the lid for the coffee pot and the holder for the coffee grounds. The pieces are fairly simple shapes and I would love to get them made out of aluminum. Where would I even start to find someone to make these?

Hello everyone. I’m not new to cnc, but I’ve never used a pro version of a software. I’m wondering what is recommended. I don’t really do any 3d carving and I’m not sure I ever really will, so that’s not really an objective of mine. I do a lot of signs and v carving. Lots of lettering with v carving. Currently I’m using carbide create. I honestly love CC and how easy it is to use. My main concern is the absolute travesty that it has in generating tool paths when v carving letters. It’s absolutely horrendous. It goes up and down a dozen different times and takes forever to carve plaque with a decent amount of words on it. Please don’t ask how I’m doing it….i know how to run and set up for v carving. It’s not me. It’s the way carbide create generates and runs tool paths. I would really love to be able to carve letters quickly and efficiently like you see in videos like “Tools Today” posts. Carbide Create cannot do that by any means, and I really don’t think that the pro version is any different. Does anyone have any experience on both; let’s say CC, and V carve pro, or another program…where you can see the difference in v carving?

From europe. I want to get into 9-12axis, and into swiss programming, and I am looking to learn a software that can handle that. (I currently program in Fusion360, and design in Solidworks.) Any opinions what am I better off learning?

I'm not quite sure if I'm writing the question in the right sub, but my project is related to Arduino and automation of the workflow.

Background:

I'm involved in casting silicone into molds for massagers, the massagers are a bit tricky and small (1 set = 20 pieces of different sizes, weighing from 1 to 8 grams). I pour silicone through a 50 ml syringe. In order to make the process less primitive, I decided to automate my production.

The idea is as follows:

Make an extruder that would use a screw gear and a nema 17 motor to squeeze silicone out of a syringe in the volume required for each individual massager.

I started looking on the Internet to see if there are similar projects and here are some examples:

1. https://karpova-lab.github.io/syringe-pump/latest/

2. https://pachterlab.github.io/poseidon/about.html

This is not what I need, but it is acceptable to take it as a basis and rework the code and form factor to adapt it to your needs.

But there is one big nuance.

I did not do anything more complicated than a 2D plotter and a question arose about the stepper motor. The projects, the links to which I sent above, use motors with a torque of 60 Ncm, and syringes there are of the same volume, but according to my calculations, 60 Ncm is too much.

To squeeze out silicone, I create a pressure in the syringe identical to compressing the air volume by 2 times, that is, 2 atmospheres. For a reserve, I will consider 3 atmospheres. So, 3 atmospheres are applied to a plunger with a cross-section of 30 mm (area approximately 7 cm2) with a force of 21 kg (3 kg per cm2).

With a screw thread pitch of 2 mm and a screw transmission efficiency of 30% (from screw to nut), a pressure force of 21 kg will be created by a stepper motor with a torque of 20 Ncm.

I want to take for my project 17HS3401S with a torque of 28 Ncm, or 17HS4401S with a torque of 40 Ncm, but I am very confused by the fact that in the projects that I gave as an example, much more powerful motors were used.

Can anyone give me a hint? Did I make a mistake in the calculations or did those who previously worked on similar projects simply not care about the mass of the final product and took much more stock than necessary?

My boyfriend recently purchased a desktop CNC machine and I’d like to get him a holiday gift/s related as he’s so excited for it to arrive soon. Being a complete newbie any suggestions?

Not looking to spend more than $100 if possible

My small tools drawer had such a mess that I could no longer find things quick. My friend told me about the gridfinity system and rest assured I could even find fitting grids to my Ikea drawers, so there was zero design effort. Printing some organizers made all the difference!

I got my hands on a couple of 5 axis tool grinders from MCT Samatic. The control on them is quite ancient looking, even though the machines are about 10 years old. I'm curious if there are any CAM options that work with tool grinders. I'm looking to program some more interesting shape and the only way I can see forward is just straight up G code.

My other thought is to retrofit a more capable controller and servos. I'm looking at Masso or Centroid as options. Looks like a cool option, the question is though - is there any 5 axis grinding capable cam for the two controllers? They mention the standard ones - Fusion, MasterCam, etc. Everything talks about milling when it comes to those and not grinding. Am I looking at just exporting the motion from the CAM and modifying the code to be more grinder friendly.

I need help! I've tried it all and keep on getting errors based around library not found and no such file or directory (upload to uno.) please help

Any models out there of similar size to the Titan 25T? Or is this the only one?

I am setting up my Shapeoko 4 and I am at then end of the installations process but when I go to finish getting it up, there is no machine tab on carbide create like in the online and printed instructions I have. I have watched other videos and they don't have any issues and It doesn't appear other have the same issues. What am I doing wrong and what should I do?

My mom has bought an secondhand SWF/ES-T1501 embroidery machine made by SunStar Precision Co., Ltd from 2001.

The machine originally used floppy disks to load design files. The previous owner has replaced the floppy reader with an Gotek emulator to be able to use USB sticks instead.
The issue that we are having is that the machine doesn't want to read and or recognize our USB stick files as floppy disks.

This is what we have done/tried:

• From what I have read is that a small and old USB stick is recommended, we have a new 2GB no brand USB stick
• To prepare this USB we have formatted it to FAT32 with an allocation size of 512 bytes
• With the software HxC Floppy Emulator we have created an 3''5 720KB DSDD FAT12, putt a .DST file on it (With less than 8 characters in its name) and saved it as "D0" in an .IMG format
• When we putt the USB into the machine and made sure that the index counter (Counter that determines what floppy image on the USB is being used) is at 000 we get this error "Er#601 :Diskette Sector Not Found"
• The image files are in the root directory
• We have tried saving the floppy disk as an .HFE file
• We have tried making multiple images with the names D0, D1, D2 and D4 and tried different index selections on the Gotek emulator
• We have tried using a 3''5 1.44MB DSHD FAT12 floppy format
• We have tried turning the machine on and off between attempts
• We have tried using an empty floppy image

Everything we have tried has resulted each time into the same error: "Er#601 :Diskette Sector Not Found"

I've also posted this on an embroidery subreddit, but since this machine is essentially a CNC machine, I'm hoping you guys might have some insights.

I've been doing some research into probes for the purpose of zeroing on the surface of jobs pre and mid-program. My intention is to use Fusion for programming and modify our existing PP to accommodate a probe. I found an OSAI manual online that shows a similar version of our controller which indicates probes are possible to integrate, pg. 46:
https://newcnc.com/wp-content/uploads/Osai-End-user-manual.pdf

I also found this probe online that specifies that its OSAI compatible:
https://amastone.com/shop/touch-probe-3d-measuring-sensor-3d-finder/

My thoughts at the moment are that we want a hard wired probe, fixed directly to the gantry and not in a tool holder in the carousel. Past that however, I am a bit stuck. I would love to be able to buy a probe kit and install it myself but I'm struggling to find good documentation on that process. Has anyone out there done something similar?

Our machine is a Maxicam Exitech M4-1530, OSAI ProcessController V5.1.4

Hi all,

Posted in r/Machinists but was wondering about opinions from the CNC community.

I am in my early 30s now and don’t have much work experience but was given an opportunity to learn CAD/CAM last year by learning first to run the programs on our routers and do some general QC post production.

I currently create jigs in NX that help with mass producing niche products.

Unfortunately, I am strictly prohibited from changing the material or dimensions of the jigs.

I was told there will be no opportunity to program for another machine (e.g. vertical 3-axis) because of company budget restrictions.

My learning opportunities feel really limited as the person I learned everything from will be leaving at the end of the year.

I want to go to another company but feel I don’t have much to offer since I only know how to program the specific types of jigs we make and it feels like a lengthy, almost esoteric process - arguably not valuable to other shops that require more variety in what is produced.

I'm only finally beginning to understand some of the design decisions after making some trivial mistakes but still feel I have a long way to go.

Would the best option be to start working as an entry-level machinist somewhere since my CAM knowledge is so basic?

Or should I go to a trade school for some foundations?

If it helps, I am much more visual in thinking and have thought about industrial design before. Thanks.

Edit1: I did purchase a year to Siemens Xcelerator recently while my license is active but wanted some opinions before I think about going any deeper.
