Flood, literally, floods. It needs good drainage and electrics all have to be fully sealed. As does the enclosure.

Have you seen zeeboy mod for it because it doesnt look like it has a stand and tray underneath the entire machine.

Re: OmioCNC report
Don't remember if it was ZFB (I think it was) but someone had a setup with a bath sitting on the deck of the machine, inside the movement envelope. Again, can't remember for sure, but I got the impression there was no pump or anything, just fill the bath and cut submerged.
Re: OmioCNC report
Ah yes that was ZFD I remember now. That was a bath on the machine table as you say. For cutting CFRP to keep the dust submerged and his lungs working.

Anyone wanting to part ways with their X8 2200L?
Re: OmioCNC report
I'm having an issue with my X6-2200L-USB that I hope someone can help me with. The spindle will not spin faster than 3000 rpm. I tested the speed using an optical tach. If I set Mach3 to 24000 rpm it is 3000 rpm. If I lower the RPM in Mach3 the spindle slows down. It used to work fine but I moved a couple years ago and its sat in the basement for a while. I finally got around to putting it back together and trying to use it but it now has the spindle issue. I haven't touched anything inside the computer or Mach3. I think everything is set up exactly as I had it before but obviously something is different. Everything else on the machine works.
Re: OmioCNC report
You might have to remove the Control box cover and measure what speed control signal you are sending to the VFD.
Its usually 0 -10VDC for 0 -24000 RPM, but you should not run the Spindle below 6000 RPM.
Measure that , if its low , disconnect fromt the VFD and try again.
If its still low, your Motion board is not outputing the correct voltage.
If it returns to correct level then your VFD is pulling the voltage down.
Re: OmioCNC report
Thanks Sterob, I will try that this weekend.
I forgot to mention that when i got it working a few weeks ago, after the move, it worked fine and I even did a nice test cut with it. I had decided to take it apart to clean and lube everything and it was after reassembly that the spindle had this issue.
I went to check the voltage of the spindle but about 2 seconds after starting the spindle the reset on Mach3 is activated and everything stops. I tried this a couple times to see if I had inadvertently activated it somehow but it does it every time.
Re: OmioCNC report
It sounds like you are trying to measure the spindle supply voltage?
Don't do that!
I was suggesting you measure the spindle speed control voltage. ( 0 - 10 vdc. )
If it WAS working ok before you did some maintenance, then you should check what you did then.
Sorry, its very hard to help like this.

Re: OmioCNC report
Has anyone cut taller z plates to increase their z travel for these OMIO CNC's?
Been thinking of making it taller so I can fit some bigger vises on the bed.
I know it will involve buying new linear rails and ball screws for the Z axis but wanted to know if it was feasible before I start planning
Re: OmioCNC report
I should have been more clear. I didn't get to test anything. When I turned the spindle on, without touching anything with a multimeter, the reset kicked in.
I've went over everything I did again and I can't figure out where I might have messed up in reassembly.
Re: OmioCNC report
Whew, finally made it to the end. You guys have troves of information here, kudos to all!
I'm waiting for my first X4-800L to show up in DHL system. I report on the current quality of the workmanship once I receive it.
In order to make a small contribution, I want to post a video I've made, showing UCCNC running UI on Mac. My main workstation is a hackintosh, I use Fusion 360 for CAD/CAM work but because Mach3 and UCCNC only run on Windows, I've found a way to control either from my Mac, switching between Fusion 360 running on Mac, and UCCNC/Mach3 running on Windows by just a lateral swipe on my touchpad.
If anyone wants to replicate my setup, holler out here or in video comments.
Thanks!
Re: OmioCNC report
Finally i had time to play around with the 4 axis. I modified a wel known Lego brick, I was able to mill it so accurate that the bricks stick
It is a great machine especially combined with Fusion 360 !
Re: OmioCNC report
Well done [mention]janlietaer [/mention]
I want to get mine up and running but have the epl orange box version and need to find or modify an existing post to use the 4th axis under f360 as I don’t want t stuff around swapping axis like brainright did in his Videos
Has anyone with the epl version managed to use the 4th axis under fusion?

@ madeinoz67
Mine is a usb version (x8 2200L, i used a post processor file i found on this forum, and modified it a little bit so that the a xis is // to the Y asis.
Re: OmioCNC report
Do you all guys subcribe F360 or not ? I got a notice from autodesk that free F360 manufacture is only for limited time ... if you know how to extend free F360 manufacture life, let me know ... thanks.
Re: OmioCNC report
@asuratman
I could be totally wrong about this, but that might be referring to the 'manufacturing extensions' (I think that's the term they use), which include things like the rotary toolpath, steep and shallow toolpath, and hold recognition for drilling.
I know that once the rotary toolpath was out of beta it was going to be something that you needed to pay for (not sure if that was going to be with their token system, or if it was just that only paying customers were going to be able to use it), but I think they opened up some of these features for a limited time, perhaps because of the whole quarantine situation. So as far as I know, Fusion 360 CAM isn't going to go away, just some of the features.
Losing the rotary toolpath is going to be super annoying, and might make me look elsewhere for a CAM solution, at least for 4-axis stuff. Although tbf the 4-axis gcode that Fusion 360 outputs is problematic anyway.
If I'm misunderstanding, I hope someone else steps in to correct me, but I think the situation is as I described.
Re: OmioCNC report
^^ That's my understanding, that a lot of the useful stuff is going to be extra cost options. They all (ie Creo, Dassaulte, Autodesk et al) do this, it just stings when something you already had suddenly gets charged extra.
Hopefully they'll let us do by the month - if you only need the rotary toolpath for one job, paying $50 for it instead of $600 for the year would be nice.
I understand the need to generate extra income to support ongoing development for these more specialised, difficult to make and maintain areas of the code. But I think Autodesk have perhaps jumped the gun a bit with this: Fusion360 is pretty reasonable for a young program but by the time I add a couple of these costed options we're now up to a similar price to the annual upgrade fee of Solidworks or Creo which, IMO, are still a hell of a lot better at a lot of things.
4th axis problem
1st post to this forum.
've really been helped with all the posts with my x8-2200. I've added a 0.5" aluminum stiffener plate to the bed, used zeeflyboy's example for self contained water cooling on the gantry and added some lexan shields on the side for safety and to help contain the dust. I've used the machine for about 2 years except for the 4th axis.
Now to my problems:
The 4th axis is at the stepper end of the bed running down the Y axis. I'm using an aspire rounding tool path at 75ipm. Intermittently the Y axis loses it's home and goes off one end or the other of the work during the cut. I started at 150ipm and the problem is a more regular, but still random so I cut the feed rate in half and that helped a lot, but occasionally it still has the issue. When the problem starts, it sounds like the stepper frequency goes way up for a moment and it loses position on the Y axis. This has led to a few broken bits.
The problem appears whether the 4th axis is connected or not, and I can hear the freq change when air cutting with the spindle powered off. The g-code looks ok and many times it works for a while, and shows the problem at different line numbers. Only thing I've checked so far is the PS voltage. With the controller disconnected it sits at 42 volts, and doesn't seem adjustable. Don't know what it should be. I haven't connected a scope to it and don't know if I can capture any meaningful data since it is so intermittent.
2nd weird issue is with the Z touch off plate. It works fine until I try to use it with any g-code loaded into mach3 (latest version). Touch off then goes to the plate as normal, and Z moves up to the home switch instead of stopping at the normal few mm above the plate. This happens every time, and I have to stop and restart mach3 with no g-code loaded to be able to use the touch plate again.
It may be that the omio xml configuration file that was included with the machine is affecting this, but I'm both g-code and xml challenged, so would really like any suggestions the group can give.
Thanks
JD
