Update 2- I realigned the stiffy and still have the same issue. Again, when jogging it’s quiet. Only when running a program it’s evident. Circle cutting is where you detect the noise the most.
Thoughts on a software update? I’m stumped.

Update 1- The grub screw is tight but, realized when I installed the stiffy bar, I didn’t put in the two screws in the top on the right side of the X axis. The left is secured because it holds the homing switch. The bar has turned so they are no longer able to be be threaded in the hole without cross threading them.
I’m guessing I will need to remove the Z and try and realign this. Not sure this is causing my problem but, it’s clear this is not correct.
I’m wondering if I should replace the wiring while I have this apart?
Thoughts?

First I have searched the forum and looked at the FAQ’s section. I will check for a bad electrical connection and a loose grub screw on the motor coupler.
What is different with my grinding issue than what others have posted is, when the machine is jogged, it doesn’t happen, it’s quiet. Yet, when running a file it’s very evident.
I will check the coupler and electrical connections and report back. Also, the file I ran didn’t lose steps. Unlikely a motor given Onefinity states this is rare. Given the machine jogs fine, I’m guessing it’s electrical.
Perplexed to say the least. I read that someone solved their issue with a software update. Given the machine ran fine for an estimated 6 hours of run time, it’s unlikely.
Any other suggestions would be welcomed.
I should have mentioned I have the Elite CNC which I received last August.
I’d try to adjust the default motor resolution to 2000 on all axes and in Masso and see if it helps. If not, you can always change it back. My Elite was chattering on circular toolpaths too, and this action helped reduce that quite significantly. I believe there is some standard for Elite machines sound on the paths that involve simultaneous X and Y movements, when their motor resolution is 400 (default). But if you’ve never run such a toolpath without a router or spindle working you might not notice it.
So I did some more research and see there are quite a few others who have had this issue. So, I’m puzzled why I have not received more assistance on the forum. So, let me start out by saying thank you!!!
To change the resolution to 2000 I would need to change the dip switches on the motors. It’s my understanding 1-4 effect the resolution. However, I can’t find anything online that indicates what they need to be changed to to reflect 2000. Also, I’m assuming there needs to be a change in the Masso controller too.
Can you tell me the positioning of the switches, 1-4?
My frustration with Onefinity is there lack a response. If I don’t get this sorted out I will try the old fashion method and call.
The switches should be changed to this position:
S1 OFF
S2 ON
S3 ON
S4 OFF
S5-S6 - no change
You can find this chart on Masso website (link above)
As for the controller - yes, you should change the step motor resolution for each axis on F1 screen.
I feel like Onefinity probably don’t like all these talks about motors’ resolution. There was a big post here I used for changing my settings this summer, and now it’s deleted. You can still see it on Google if you look for “Elite machine low motor resolution”.
I just look at the link you sent me. I will make this change tomorrow when I’m at the shop. The video explaining the Masso, is a guy I knew (Peter), from my day’s on the Joe 4X4 forum, we both built our own CNC’s. Small world.
Again, appreciate the help. Will report back to see if this resolved my issue.
Make sure you have contacted support directly, as the forums are helpful but they do not replace the official email support process. Also make sure to now factor in our Canadian Thanksgiving holiday weekend.
We will be issuing an official service bulletin changing the prr from 400 - 2000 from the factory in the next month.
Feel free to change the prr now.
After much internal testing, working with masso, and customer feedback, 2000 prr increases resolutions, removes the “grinding noise”, adds increased smoothness, and leaves no noticeable loss of torque.
To do this, with power off:
Change all motors:
Turn 1 and 4 dip white dip switch to off/down. All the rest leave on/up.
Go to the f1 page. Change all axis settings digitally on the prr lib from 400 to 2000 to match the dip switch change and hit save.
Reboot and enjoy a much smoother machine.
It certainly can be, and definitely has its place in the list of support options. Onefinity staff constantly monitor the forums, and because it is likely many users with questions or experiencing issues will come here first, problems impacting larger numbers of owners may present themselves faster here vs through the email support channel.
I have learned a great deal over the years about my machine, and machining in general, and often go the Masso or Onefinity forums first (after checking all the wonderful online resources of course ).
Often, I ask the forums first to see if a particular issue I have is of my own doing, other times it may be a small question that I do not feel needs me contacting support directly. The other reason is that both the aforementioned forums have knowledgeable and supportive members that are always willing to share experience and advice, any time or day.
I’m will make changes shortly. I assume changes should also occur on the Z-axis too?
I will also reach out to Onefinity directly should I have any future questions. The forum serves a valuable service allowing users to see and work collectively when there are problems while also sharing successes. This being one of them.
Thanks for all the help, the changes in resolution resolved the grinding noise. The forum was a contributing factor in selecting Onefinity. Reminds me of the Factory Five forum where help is appreciated and welcomed.
