Very good video Sir Can you plz deeply describe the electrnical part of tool changer with mach3 board and mach3 calibration

Sweet build! Very impressive.

mind blown!! Holy crap that is awesome.

You do good work and I understand why your company would allow you to do your own projects; I can tell that you learned a lot about design and construction of a somewhat advanced tool and your company will be getting a better employee in exchange for a little tool time.

+Luka Radakovic Thanks hopefully ill have enough done for one next weekend!

Ratchet is not enough - there must be a Hirth coupling.

Possibly out of place, i'm new to cnc machining and i'm looking at designing a gearbox planning to mill it out of a solid chunk of aluminum it won't be any bigger than the main body you've built here . Do you think i could get any advice on machining something like that? i'm guessing the only way to do it is with a 5 axis am i right? how else would you do it ?

@TabletopMachineShop

5 жыл бұрын

I'd have to see the part to comment on specifics, but for a part like this, and indeed I would say most parts, you can get away quite comfortably with 3 axis. The trick is a good setup and being able to locate well. I did this part in 5 setups on a 3 axis, though a 5 axis could have done it in one!

I hope that you put together a drawing or sketch package on this. someday.

Wonderful video, you have a great step-by-step pragmatic teaching style. Amazing project!

could use an mechanic pin in/out to clamp that keeping on position the tool adding an push button option one to change tool other to clamp

Subscribed. One minor change I humbly suggest for version 2 is the addition of an encoder so your computer can determine which position is currently selected. An optical encoder should work but might have problems with cutting fluids/coolant. A magnet based encoder would be very reliable though

Nice job sir. What you really needed between the stepper and the shaft was an 'Oldham coupling'. They are a really nice way of isolating two shafts that are not completely concentric. I can't readily explain how they work here, but just google 'Oldham coupling', and you will see what I mean.

Could you not just mount the motor on rubber standoffs? That'd allow for a small amount of misalignment without otherwise affecting its operation. For this application it'd likely be all you'd need.

gained another sub :) I have the same digisparks running 12V in, and they run pretty cool... unless you were using it to feed the power to the poululu board...(digisparks only handle up to 500ma on the voltage regulator), so I run it through to a relay instead... mine is used to run a set of 12v lights... let me know if you want more details...

Hi HarreyHHH, As far as I can tell, the digispark is in parallel to the stepper driver so it shouldn't be getting all of the current.. Do I need some kind of current limiting resistor?

Where to get 3d model?

You are driving the stepper with that little chip? If so, that may be why it got hot. You need some kind of motor driver I'd think. Great build!

+Nate P thanks Nate! Ive learned that sometimes you need to just dive into machining to encounter mistakes you wouldn't have caught in CAD. Ive tried using only CAD with no prototyping before and i've found that the idea hits a wall pretty quickly!

Would you consider to share the macro for Mach3 ? I mean I have one, but mine work with a humble pneumatic actuator, that push the tool out to rotate, then it locks back in place.. but I never have been able to figure it out how to make the Visual-basic equation to make it work properly! Don't get me wrong.. If I set my tools in series.. 1, 2, 3. It follows and works, but It make me feel a bit bad about my self that I can not just go back to say if I'm on t3 M06, and need to go back to T1 M06.. I just can't do that... thanks for posting and best of luck...

You don't have to have VB in your script if you don't know VB. You can use the Mach script engine (i think it is provided by Cypress Software) which is already integrated in the software, and standard logical arguments to control position (if / then/ else). If you are knowledgeable in using and manipulating spreadsheets you can use that knowledge to make your macros.

You could have removed the back tool changer bearing leaving only the front motor bearing to help with that problem.

Amazing compact toolchancher ! do you sell these ? This DRV Stepper Drivers always overheat.

This is awesome. I've been following you for a while on IG and I'm really excited to see this complete! If you setup a patreon I will definitely donate for plans.

@TabletopMachineShop

7 жыл бұрын

I appreciate that and I appreciate you following me this long! I'll certainly mention it if I decide to go ahead with it!

Shafts that bearings run on should be as round as the bearing, the bearing tends to deform to fit the shaft. They will bridge over small holes/depressions, but high spots will deform the inner race. Excess shaft thickness will reduce bearing clearance by an equal amount for a solid shaft, a hollow shaft should have less effect, but no experience there. I can see the high spots on your shaft at std resolution.

Greetings,I would be interested in getting a copy of the cad models if you have any?If not I could be interested in generating them (STL or STP) for you in exchange for the design to make a copy for myself of the tool changer for my mini lathe, Really nice design...PLEASE ADVISE....MASTER LEE

Very nice thanks

Nice job on your build

Did you get any chatter when in use? I would think the tool would need to be locked in place bidirectionally.. even though the cutting force is pushing against your ratchet I'd expect the tool to bounce as the chip breaks.. awesome work.. if the place you work at is hiring let me know 😂

Now you just need to buy a cast iron furnace and sell small work envelope super heavy duty lathes. You can even 3d print the patterns these days, some of the filament burns away and leaves almost zero dust. I think they coat the 3d printed plastic parts with some kind of ceramic/silica material.
