OmioCNC report

[Mmpie]

For the last few weeks I've been building a new electronics cabinet for my X6-2200L centered around a UC300ETH and UB1 breakout board. Just recently I figured out VFD speed control and decided to make a video on it. I know there's a few guys here looking to make the transition over from Mach3 to UCCNC as well so I'm going to try to do my best to document my progress in video format.
Current issue is that I'm not sending a pure 0-10V analog speed signal to the VFD but something much closer to 0-13V so I'll have to play around with VFD parameters and UCCNC's PWM configuration to resolve that. Next step is to clean up the wiring, make some chips, and start working on preparing for the ATC spindle that I ordered from JGL.

You’re putting an ATC spindle on the X6?

For VFD control, use modbus. You will get perfect RPM’s and data fed back to mach3 which you can have shown up on the mach3 screen to see how things are running.

I thought about doing that, but I bauked at the learning curve to get the Modbus comms working......It may not be hard, I don't know.
I've just had bad experiences in the past...lol

One day I'll look at it......

Somewhere in this thread there are step-by-step instructions on how to do it.

Modbus isn’t that difficult actually. If you have any knowledge of pc coding you’ll find it a breeze. I didn’t but I looked at it and googled it, and looked a bit more, scratched my head a few times then suddenly it all clicked and I managed to do exactly what I wanted to do really quite simply.

Definitely worth doing you can have any info from your vfd from estimated RPM (pretty damn accurate) to voltage to how much current your spindle is pulling read out all in real time right on your screen in Mach3 and your programmed spindle speed will be pretty much dead nuts accurate - tested mine with a cheap digital tacho at 1000 rpm increments all the way to 24000 and every single speed the tacho read to within 10 RPM.

If you get more advanced I’m pretty certain you could have safety macro’s written so if you pull too much current or whatever it could automatically soft estop the machine to prevent any real damage from taking place. Can happen when your cutters start to go dull which is usually when you’re looking the other way.

Made another video going over the progress I've made upgrading the X6 with an ATC spindle and my UCCNC electronics. Whats been very pleasant is that the X6 router required minimal modification so far, just a larger drag chain had to be installed which required a few new holes to be drill and tapped.
Also made a nice little modification on the X axis, by modifying the limit switch I've been able to extend the X axis travel to 365mm (original was 350 I believe) which was just enough for me to be able to fit 8 ISO20 tool holders on the tool rack.
One issue I'm trying to tackle right now is bed leveling and finding the ideal approach between shimming the gantry, tramming the spindle, and surfacing the bed/spoilboard.
The biggest obstacle now is designing, machining, and assembling the pneumatic tool rack and enclosure for the tool holders. Due to the small size of the table it's far too easy to get chips onto the tool holders and the dust blowoff isn't perfect. I expect to have a solution and a 90%+ done machine within the next few weeks.

If anyone feels like this deserves it's own thread please let me know, I don't want to put too much work into documenting my progress however I'm more than happy to share the things that I've learned with anyone looking to undertake a similar endeavor.

[Sterob]

Nice work. You have put a lot of hours in that project already.

Has anyone found where I can buy more of the square M6 nuts that this machine came with? DIN557 appears to be smaller, no luck finding any other standards to go off of.

[dharmic]

Pretty sure someone did a while back, somewhere in this behemoth of a thread.

I ended up using coach bolts upside down in the T slots and screwing the nuts down on top.

[RCaffin]

WHY use square nuts? Why not hex?
Have you tried eBay? They have plenty.

Cheers

Square for T nuts. Less likely to spin when you're loading up the clamping force, bigger surface area means less likely to create indent in the back face of the T track.

[Mmpie]

Wow. Great job sticking that on.

I use drop in t-nuts for the Bosch rexroth profile. Very handy as if you’ve got things set up you can still drop a t-nut in from the top, no need to move stuff to slide it in.

I took a long break from working on the router (burning out and other commitments) but I'm back with another update video. This time I'm happy to report that the machine is now capable of automatic tool changes with the ATC spindle and pneumatically actuated tool rack. I'll be making a separate thread soon where I plan on sharing my macros and finer details about the machine since I've been getting a lot of inquiries about it.

That’s brilliant, great job

Has anyone located documentation on the controller card yoocnc m3 jb4

My X6 came with one of these and I am failing miserably trying to use the output pins on the card.

Tried googling/bing and didn't identify any docs online.

[Sterob]

No manual but some info here:

Greetings everyone - thanks for all the great info in this thread. I received my X4-800L-USB today and seem to be missing the quick start guide and configuration files. Does anyone else have these available? I wrote to Lance but since it's the weekend I figured I'd ask here as well to see if I can get up and running. Thanks!

[Pyronious]

OmioCNC got back to me (in less than 3 hours, on a weekend) and provided links to the instructions and setup files. Here they are in case anyone else needs them:

1). Manual kit and setting files link for X4-800L

Please read the "Mach3-ConfigurationV3.pdf" first, and follow the instructions step by step.

Belarusian:

A very impressive ATC build!

I noticed you are using the Barrowich flowmeter. Is this the FBFT032 flowmeter, and what is the typical flowrate (L/hr) does your cooling loop achieves with the Omio Chinese spindle? Are you impressed with the quality and performance of this meter, and would you purchase it again?

Thanks!

does anyone have plans for adding a flood coolant tray to these machines. I've seen zeeflyboys images which show some sort of DIY tank enclousyre but struggling to understand how it was done.

It would be done by building it a stand and enclosure with tank underneath and slanted drainage, same as any machine. The whole thing would need rewiring properly and I have no idea how waterproof stepper motors are, the ones on the OMIO I would expect not at all.
