CNC Build Ep 7: Custom Mach 4 ATC Tool Station Setup! Setting up ATC Tool Pockets / Tool Forks /S30C

Рет қаралды 6,996

Күн бұрын

Hey CNC Woodworkers! This is my custom Mach 4 Screen Set and code to make setting up an Automatic Tool Changer super easy in Mach 4, with no macro editing required. The hard part about setting up an ATC is finding the "tool station positions", also known as "tool pockets" or "tool forks". The User Interface I added makes it a lot easier to do this process. I walk through how to download and install the screen set. Then I go into setting up the Input and Output pin mappings in Mach 4 for my Avid CNC and ATC spindle. I'm using a HITECO QD-1F spindle from CNC Depot, but their popular S30 and S30C ATC spindle will also work fine with this screen set. In fact, any ATC spindle will work with it; the only difference may be what pins are actually controlling the relays. The code is fairly generic, and will probably work with any Mach 4 CNC machine, but I am using an Avid CNC and requires their release of Mach 4 (it has some things I build upon). Once you setup all the pocket positions, you can use any screen set you want, as long as you still use my custom Macros for doing the Tool Change. This screen set is fairly specific to a spindle-based CNC machine; I removed a lot of things related to a torch machine (plasma table CNC) and the laser. The screen set is open source and free. I make no warranty on it working...use at your own risk!
EDIT: for the slide distance, you will also want to ensure your largest diameter bit will clear the tool fork, not just the collet! My largest is 2", which is about the diameter of the collet.

Hi Corbin, this series of videos and the corresponding links and downloadable stuff is so completely and totally outstanding, that I'm at a loss for words. Three cheers for this incredible accomplishment. Thank you for this amazing contribution to fellow CNC-ers around the world! All the best

Thank you so much all of the videos Corbin! I keep forgetting to turn on the air so having that pressure sensing info was fantastic! I clicked on your referral link to order the switch, got it today, and got it all hooked up! Works great! Your screen is well done and way better than mine so I'm using that too! It would be a long list if I were to itemize everything your videos were helpful with so I'll stop with that! I appreciate all the time and effort you put into these vids, sharing your screens, etc, thanks!

This has been incredibly helpful - because of you my ATC system is basically set up (minus the beautiful wiring). I don't own your machine but I own Avids old electronics which I've completely changed at this point. I have a chinese 5.5kw water cooled spindle and this has been relatively easy to set up. Thanks for your help. This is amazing.

Hello Corbin. Many thanks for doing these informative ATC videos. They are a great help. I am in the beginning of adding ATC to my shop-built CNC router. I have a question about the racks and forks for the tool holders. The question is why is it necessary to design the forks to require a side-slide motion to fetch or return a tool? Why can't the forks be designed to allow the ATC spindle to simply come straight down over a fork, grab the tool, and then go straight up? And return a tool by coming straight down over the fork, release the tool, and then leave going straight up. Thanks.

@CorbinDunn Ай бұрын

Hi Richard, My apologies for the slow reply; I was gone for a bit. Some racks do the "drop in" style, and I have seen them. I had read somewhere about some problem with them...but at this point I kind of forget what it was. Most industrial CNC machines seem to use the slide in version, so I figured it was the best way to do it.

Great work on this! Thank you for sharing. I am trying to change the UI of Mach4 just for what the relays say, can you please recommend how to learn this? Is there a channel on KZfaq that helps with this or anything. Also, can you please share how you got the pendent to work with Mach4.

Editing the names is super easy. Just Disable the machine, and then you should see a menu item at the top to edit the screen (I can't check the name at this moment as i'm away from my machine). In Edit mode...click on the label, and there is an inspector on the left that has the Label for it...change it. Super easy! Backup the file first if you are worried you might mess something up. Pendant: VistaCNC has a driver and directions on how to install it.

Corbin, i installed your screen set over the weekend. It's awesome! I went ahead and changed everything over to metric. This was relatively easy to figure out as well. I don't have a pendant, is there an easy way to bring the jog feature back into the new screen set? Thanks again!

@CorbinDunn 11 ай бұрын

Awesome! Do you use a keyboard? Can you jog with that? Or do you preview a touch screen? I've been super curious if people used this feature or not...sounds like I should find somewhere to put it back in the screen. FYI - you can use any other screen set you like once you get it all setup; the M6 tool change macro will still work fine with another screen set.

These videos have been extremely helpful. I recently upgraded my ESS along with Mach 4 at the suggestion of AVID to solve some motion issues. I found the problem with the motion issue, (not the software), and went to set up my ATC again. It had been working previously with the older software. Now, when I go to assign Pin 1:1 to Output #6 I can't get Pin 1:1 to show up in the pull down menu and I can't write it in. Any suggestions would be much appreciated.

@CorbinDunn 7 ай бұрын

I'm not too sure why things won't show up in the menu; I don't do it often enough to be really familiar with all the Mach 4 UI for the setup. I'm guessing the mapping doesn't exist where it expects it. It might be easiest to just start over and follow the pin mapping directions from the start to reset it all correctly.

Hi Corbin! Thank you so much for making a great Mach 3/ 4 screen set. I have just 1 issue. The Z bump isn't reactive enough. Its pressing on the fork bending it. So when a tool is picked up, the drawbar is pushing the fork down. When a tool is released, the spindle isn't going up soon enough when the drawbar releases it. I don't understand the line you put in the lua file for Zbump? MCCntlGcodeExecuteWait("G00 G90 G53 Z%.4f", zPos + ToolForks.GetZBump()) -- rapid here seems scary..but okay There seams to be a pause before the spindle moves up or down with the drawbar action. Then the movement is too fast once it goes. I am using the same Zbump amount as I did with the CNC Depot screen set, that worked just fine, no fork bending. Any insight to correct the fork bending? Thank you.

@ohfatkitty 5 ай бұрын

I got it to stop bending the forks by commenting out 2 lines. Line 259 MCCntlGcodeExecuteWait("G04 P%.4f", 0.3) and Line 310 MCCntlGcodeExecuteWait("G04 P%.4f", 0.2) 😁

@CorbinDunn 5 ай бұрын

Great, I'm glad you got it figured out! My spindle seems to release a lot slower than other peoples, and if I don't have the pauses it will potentially start to rip the forks away on release. Maybe I can make them optional for other people.

Hi Corbin, i've just discovered yours videos ...very cool.................for this one you're with Mach 4...do you know if it'ld be possible with GRBL1.1 protocole ?? thank's a lot Philip

@CorbinDunn 6 ай бұрын

Hi Philip - I hadn't heard of GRBL; I think it is a Gcode interpreter/controller based on some quick googling. It looks pretty cool! So, if I understand it right, it does the same thing that Mach 4 does. Mach 4 is the Gcode interpreter, and it communicates with some hardware that actually does the motion control, which for an Avid CNC that is usually an Ethernet Smooth Stepper (ESS). So....I don't really know the answer to your question. What are you trying to do?

Does this only work with avid ess boards. Or will the open share work with hicon controllers.

@CorbinDunn 8 ай бұрын

I started with Avid's version of Mach 4, so it has some dependencies on it for things like the touch plate. Other than that, the code is fairly generic; I could probably remove all Avid-specific things and make it more generic.

@CorbinDunn 8 ай бұрын

Although, some things, such sending the signal to open the drawbar (and close it), are abstracted via Mach 4's plugin mapping, and I talk about how to hook it up via ESS. So, you could simply map it to whatever mechanism your controller board uses. In theory, it should work, but I'm sure it'll take some fiddling to figure out any problems.
