- This is my third video on the RapidChange ATC I have installed on my AVID CNC. In this video I cover the internal parts that grip the collet nut, and how they are replaced, as well as their durability.
Great video. Also so far I have bought every product you have made a video on and shown a demo on. You do a great job explaining things! Keep the videos coming!
To include the Avid CNC machine!
@@jonathansholar4437 Thanks, I'm glad you find them helpful :-)
Lol... I'm in the same boat.
This has been an expensive channel to be subscribed to.
Fantastic video, as always.
@@pokiejackson3364 LOL. My wife says most of my viewer's wives probably hate me because of the tool expenses, but I just say, "well, now we can make you something nice for the house". 🙂
@@pokiejackson3364 yes!!!!
We print them with ABS, I have tested a lot of materials. I settled with ABS because they can absorb the shock without crumbling which is what happend with PC/CF. Under normal use they hold up well. Yes the caps and Bodys are HPDE.
They are really tough. I have seem some printed parts that seem to split apart easily, but I really abused these and none of them split. You must have a good printer :-)
@@JNWoodworks We use the Bambu Labs X1 Carbon with high temps.
@@RapidChangeATC Dang, that prints so nice, now I'm tempted to get into 3D printing too. This could turn out to be an expensive little experiment :-)
@@RapidChangeATC your prints look great. And the engineering on this changer is AMAZING. Pure genius!
@@iagmr Hey thank you for that I really appreciate it
I had problems initially with it not always being properly centered in the pocket. Turned out to be the cheap roller style limit switches on my machine just werent up to the task. I replaced with some omron switches and better mounting/positioning so they actuate squarely and its been rock solid ever since.
Ya, homing accuracy is very important for this. My machine has proximity sensors and it has always been good, but with regular mechanical switches you would want to have good ones.
i had not seen this before. There is a sort of similar solution from Frank (a diy'er from germany but forgot his name) but this is an elegant solution ...
How soon do you think Avid will bless this as their "official" ATC and co-market it they way they did with the laser?
I have no idea. There are a lot of AVID customers who really need a full blown high end ATC, so if they do an ATC, I think it may be more likely they go that way first. I don't know they they have the resources to support both. Will be interesting to see what they eventually do.
Another question is why do you show a different spring and nut with balls than what you actually installed in your rapid change? looks like a bigger spring that would not fit and the part with the ball bearings has a large hole and the ones you installed back in had a smaller through hole??
You were paying good attention :-). I was saving that for the next video, but Rapid Change has improved the design. I have one of the last old ones that had about a 5/8" hole in the center. The new design has a 31mm hole. When they sent me replacements they sent 3 old ones and 3 new ones in case I wanted to try the new ones. Of course I did, so I machined out 3 of the pockets to support the new spring and holder so now I have 3 of the new and 3 old. The new size now covers a very high percentage of the bits one would run.
What kind of software is there?
I run a printnc with iosender. I was looking at getting a kit but worried about needing to do the leg work in the post processor myself..
For a diy hobbiest I’m kinda lazy…
The only thing the post processor needs to do is insert the m6 macro call in the right spot in the Gcode and call out the correct tool. That is typically already there (it is in Vectric products I know).
Then you have a macro for m6 installed in Mach4. They are working on the mach4 screenset yet, but the ones they did for other controllers look nice, so I'm anticipating this one will too.
In case you damage those parts again, Is there an available stl file or they only offer it for sale?
I would assume that they are selling them, not giving the files away since they are trying to make a business out of it. You can find contact info for them on their website: rapidchangeatc.com/
One of my goals is to test the wear of these to make sure they last a reasonably long time. So far I haven't seen any issues with these parts unless you do someting dumb like I did.
Ok. Im really close to getting this atc system for my er20 spindle. Thanks!
what do you do about your dust shoe?
I have been working on a new dust shoe design in my head for a while now. Once I get done testing the ATC if I feel it is something I am going to keep using in the future (I'm not sure that I really need an ATC, I don't do that many bit changes) I will design a shoe that works with it.
