First I want to say Brandon is an asset to the team and have been working with him , so I bought my second cnc which is hdm v3 and it’s horrible and so slow to doing the 3 d program and I have done all I think I can to get it to go the speed needed. My question is why is it not cutting a simple 2 d circle smoothly I have played with the setting and still no good I have the v8 carbide create and motion 651 he tells me that there is nothing wrong but not cutting a simple circle without pulsating I have tried resetting the resolution and every time it does the same . The reason I’m needing help faster due to the team must be super busy and I’m needing to get the machine running asap. I really am wandering if the software is not up to date enough to even cut a smooth circle and if can please let me know . If I set both machines the 4 XXL and the hdm v3 to cut a circle the XXL will beat it and that scares me after paying $5800. Any suggestions . Thank you Danny
Upload a file which you are having difficulty with?
Which feeds and speeds are you using?
Are you using the same computer to control both the XXL and the HDM?
First it’s a basic circle
Using separate new computer so I run both machines
Feed is 80 at 22000 rpm
I noticed on your all’s video cutting the aluminum pumpkin was using fusion 360 is that because of carbide has issues with that on the hdm?
Carbide Create should work as expected on an HDM — folks use Fusion 360 for its 3D modeling capabilities and its toolpath generation.
Things which have been found to cause slow movement on machines:
- having the Log window open
- USB incompatibilities
- EMI
- installing OS updates in the background
If you have a computer which works well with the XXL, and a different computer which has problems with the HDM then the simplest thing to do would be to swap the computers and then to run each file on both machines as an “air cut” with no stock loaded and the spindle off.
Can the configuration and/or grbl settings remain the same if he runs the 4xxl and HDM from the same computer or would they need updated from one machine to the other?
It will be necessary to configure for the different machine on each computer:
We used Fusion because it has more advanced toolpath options that work better in aluminum.
Can you share a gcode or carbide create file? I know “it’s just a circle”, but I’d like to try and see if there’s anything weird going on behind the scenes with the commands being issued to the machine.
It would be interesting to see the same file run on both machines. If the same gcode produces different results, it might be machine related.
It would also be interesting to see the circle files used for testing each machine if they are different.
I think for curves, the number of commands can get too high for the controller. In my experience this can look like more stuttering and much slower average feeds as the controller buffers.
The way it should work is Carbide Motion downloads G-code to Grbl up to the capacity of the buffer and Grbl uses the content of the buffer for its motion planner so as to produce movement which matches the G-code — if folks are not getting behaviour to match this, please let us know all the specifics and send in files which consistently cause this problem and we will try to look into it.
My XXL is running on 649 motion and I was told hdm won’t recognize older versions and what really scares me 90 percent of the time I’m doing 3d programs . If the 3d version of carbide is not suitable for hdm then what’s a guy to do . What version of fusion 360 that will work and don’t cost an arm and a leg ,I’m doing this as a side hustle . I will go through the list that you suggested that might be causing the studdering. If no luck I will upload the "simple circle"again for you guys to look at .
Well been doing several test on my simple circle and all are failures and to make it even worse a screw fell out and no clue where it goes
I’m really having buyers remorse and am hating this machine and I don’t want to be like this. I hope a call will come soon today when they open i did put a request in. Have not tried other computer yet because it’s cc7 and motion is 649 and I was told it won’t recognize these. And I’m not updating it’s working to well.
The screw should be an oil port cover:

Framing it as:
CM build 649 running an XXL is faster/better than CM build 651 running an HDM
seems like something which we can research.
My recommendation would be to check that you have the CM649 installer backed up on the computer running the XXL, then install CM651 and try that — if the XXL then develops the problem, it would then seem to be a version issue — reinstall 649 and see if it then goes away.
If it doesn’t, then try the old computer running 651 which worked well w/ the XXL on the HDM.
Please let us know what you find out.
Looked all over for location of screw do you do you have a image where they screws are located . I had a feeling it was a port screw. Also did what I could on suggestions and still having the issues. So the main question is Is the 3d program and or latest motion sub standard with the hdm
Thanks Will I will do the switch out in a little while.
The folks at support should be able to assist with finding where the screw came from — when one vibrated free from my SO5 Pro I found it necessary to use a bright flashlight and to methodically check all of the linear blocks (still not sure how it got from the left of the gantry to the right of the machine bed…).
Note that the resolution setting in Carbide Create only changes the resolution when viewing on the computer screen.This setting has no impact on how fine or coarse the design will be cut. Seeing no difference in the cut when changing resolution is expected.
Thanks for info I seen that also if the carbide 3d program doesn’t work correctly where do I go without costing a ton . Fusion 360 for hobbyist is 2 d only which I fall in the category so if not carbide or fusion then what being 90 percent I do is 3d on my wood products.thx danny
Carbide Create should work, and since you haven’t uploaded a .c2d file we can’t check and see if it is the problem.
The other notable option is MeshCAM:
(there are various other options including some free/opensource, but I haven’t tried any of them seriously since pyCAM which was a very long while ago)
and there is a list of 3D CAD options:
Or, for an all-in-one option see:
but, I suspect the problem is with the computer which is hooked up to the HDM — my usual recommendations there:
- reboot
- check for updates
- shutdown
- restart
- verify all updates are installed
- make sure nothing which is unnecessary is running
- start Carbide Motion and connect to the machine
Note that I am not affiliated with Carbide 3d, so have no “skin in the game”. I am certain that a gcode file created in V7 or V8 can be cut on both the HDM and the XXL. You are running the Pro version of CC (3d design is only available in the Pro version) and the Pro version allows you to save toolpaths in a separate file than the c2d file. This separate file is the gcode and it is a text file, readable by any grbl machine (even those not running CM). It is not modified by CM, only read. Using the circle design c2d file that has had issues, using the new computer with V8, one could save the toolpath to a separate file and cut that same toolpath file on both machines using the same bit and material. This is with no change in software/configuration on the two machines( HDM with new computer, CM 651, CC V8 and XXL on old computer , CM 649, CC V7). When this is done, if the problems are not seen on the XXL, the file (and CC) are confirmed to not be the source of the problem. Since CM only reads a gcode file it is also unlikely to be the source of the problem. Without seeing the actual files and troubleshooting, I can only speculate but suspect the issue may be a buffering/communication issue between the new computer and the HDM. If so, this is good news because it is probably remedied by a change in settings on the new computer, requiring no change in software vendors or versions.
