TOADBOT: ROS Mapping Amazon's AWS Warehouse (Beta)
TOADBOT MAPPING SIMULATION - (Beta)
Running the still under development, ToadBot in RViz and Gazebo with Amazon's AWS Warehouse. Point Cloud and RTAB Mapping was used to map the warehouse. Had some communication issues with rosserial in this beta test. Additionally had some syncing issues with the video.

Testing the Homemade 4th Axis CNC Milling Machine
Просмотров 3,3 тыс.2 года назад
TOADMILL: 4 AXIS CNC HOME BUILT MILLING MACHINE Test cutting 1" 6061 aluminum round stock with the 4th Axis Homemade Milling Machine. Not sure why on Darth Vader's front portion of the helmet had a rougher finish compared to other portions. Didn't hear any chatter. I wonder if it is because of the rotary change of direction. If anyone knows why, shoot off a comment below. Components Used: - 4 A...
TOADMILL: 4 AXIS ROTARY CNC MILL (DIY)
Просмотров 2,3 тыс.2 года назад
TOADMILL CNC This is my first attempt in building a CNC milling machine with a 4th axis rotary attachment. Seems to have good tolerances and am pleased how it is able to cut aluminum metal without issue. Having said that, the feeds and speeds were set pretty slow and shallow for testing.

Can u do more videos about ur mill please?
They Bulldog Acts Like A Piggy
Can you upload a tutorial on how to do this? I am attempting to do something like this on the 4th axis with bigger stock but my bits plunge too deep because the last operation did not remove those areas and so it overloads the bit and breaks it. Idk how to fix that.
Nice work. The finish on right side of the mouth area appears to be worse than the left. This was probably from the roughing pass, due to the roughing pass being too close to the finish size. Try leaving .020"-.030" stock during roughing, .005"-.010" for semi-roughing, and .002"-.005" for finishing. Could also be backlash in your machine or 4th axis. Easy to check with an indicator. Not sure of your exact setup, just my 2 cents.
Didn't consider that. Thank you!
Hi do you have blueprints of this lathe ? Can you send it to email ?
One of the reasons why it's chattering is because your workpiece is sticking out too much. As a general rule, you should ALWAYS have your workpiece as close to the chuck as possible.
just a suggestion. Your workpiece and cutting tool is sticking out too much bring them in and it should reduce chatter considerably.
Great point!
Great work man:) I know I am late to the game, but to anyone else, don't ever buy these shiny, aluminium quick release tool posts for anything else that turning plastic. They are horrible. I bought one, and it just isn't stiff enough or hold the the tool well enough. Bought a proper steel one right as soon as I realized and they are worth the money. The x3 cheaper alu one is not!
Cool, thanks
what software did you use
I used VCarve Pro, made by Vectric (www.vectric.com/products/vcarve-pro) to import 3D models (STP, OBJ, STEP, etc) and generate the gcode necessary for the 4th axis. VCarve makes it super easy and is one of the few programs I found that supports the 4th rotary axis.
hello ，where is the article？how it can be use ？thanks！
Solvent used?
Mineral Oil was used 😀
I'm Confused ., Is this a prototype, Looks Cool, I'd sure like to see more info . . .
Yeah, it's just a prototype. Was just playing around with some junk parts to warm up my garage. Search youtube for diy waste oil burner. There are quite a bit of videos, better than mine that will show you how to make one.
In addition to the waste oil burner, I've added two peltier coolers with heatsinks to power the fan/blower from the heat generated from the exhaust stack. It takes about 5 minutes for the burner to heat-up and generate enough power to start the motors. The temperature variance between the exhaust and the heatsinks is what enables the peltier coolers to generate electricity.
Nice build but that tool looks and sounds dull AF. Put a razor sharp HSS tool or a proper ground carbide tool (the shiny inserts) and I bet it will cut great
Thanks for the tips!
@@ToadLabs Yeah, the inserts that are titled as meant for cutting alu are really sharp - and they are indeed shiny.
Great. Can it do threading
Thanks! Yes, it can do threading. The Centroid Acorn CNC board and the application it comes with makes it easy to do threading.
Here is a link to the control board I used. www.centroidcnc.com/centroid_diy/acorn_cnc_controller.html
Looks pretty sweet, how much did it cost you overall?
Thanks! My goal was to spend under a $1K, but probably turned out costing more around $1,300. Many of the parts i've collected over the years and/or purchased them when they came up on sale (Pre-2020), so it's just a guesstimate.
@@ToadLabs Damn that seems pretty low. Id definitely like to see more of what youve made and maybe how you put it together. I'm not the most tech savy but putting this all together would be something m interested in
Sounds like lots of vibrations on the tool.
Can you tell me in a future video how to make the tool auto change of lathe machine?
Doesn't sound too good.
👍 But the vibrations sounds bad...
Uff......sounds terrible. Loads of chatter
why not testing in CUZK or aluminium? I hear this poor thing screaming
Any chance you could document the build?
Your tool is sticking out way too far Move it closer to the toolpost. That is why it is chattering
You are going to have to get rid of the round linear rods and go with truck and rails to get it anywhere near rigid enough to get rid of the chatter. This is the rails deflecting causing that. Round linear rod, especially unsupported should not be used for load bearing tools. Fine for 3D printers, camera slides, and simple light load motion systems, but not any load bearing tool. You could have spent less on a 7x14 and converted it to CNC and had a much more rigid machine.
Listen brother, you're probably right about the deflection in the linear rails. But to say "you could have spent less on a 7x14" is just plain stupid. This is a DIY project, can't you appreciate that most projects don't go perfect the first time round? You know what that is called? Learning from experience. Not to mention its far more gratifying to build something from the ground up than it is to retrofit an already capable machine. So go and take you're infinite wisdom somewhere else, maybe to your perfect projects.
What sort of linear rails are you using?
Show us how please.
sounds like heavy chatter
Great work
Beautiful work 👍🏻
Thanks a lot 😊
