2021/20right now. Been having exact same issues. Roland tech was out last fall and mill checked out with no problems. They went ahead and changed a Y gear or something because we were under warranty. Couple weeks later problem re-appeared getting worse daily. Problem seems to have coincided with getting a new computer and installing window 10 plus at the time version 17. We are now using version 20 sum 3D and problems have not gone away. Did you ever find a cure?
exact same issue hear, ended up complaining enough they replaced the entire mill, and now its back to where it was after a couple months of the brand new unit. Roland doesnt know how to fix it, been going on for two years.

I heard that Roland replaced the unit and that the replacement didn't still have the problem. It took probably 6months before they did that including them having the mill for over 3 months. I am fortunately no longer with that lab so I can't comment further other than, maybe buy something not made by Roland? which I know isn't particularly helpful at this point. It's unfortunate because I used to really love their product

Had a bur snap because it stuck during a wax (veneer) mill. Immediatly started getting parting lines. Callibrated three times, spindle run-in, bur change test, re-tighten collet, re-boot and unplug computer, no change. Ran a mill on the 5 axis modes, and it completely solved the problem. Went back to 3+2 mode, no more lines. Been line-free for the last 20 units. Decided just to stick with 5 axis even though it takes a little longer.

Hello, I'm looking to see if anybody else has any experience with this or if anybody has any thoughts on what might be causing it, so far our support lines haven't been able to help.

When milling with either the Roland 51 or 52 we are getting really noticeable parting line issues and the milling quality on the margin side of the parting line tends to be extremely rough and sometimes also has margin chipping. The results were even worse on the 52 and support had us send it back to Roland to have the Y axis ball screw replaced. The pictured results are from both mills and after the 52 was fixed. We have tried both 2019 and 2020 strategies in Millbox some provided by Zahn and some coming directly from Roland. So far those haven't made a difference. I have used Roland mills for over 10 years and have seen them mill much better than this and the fact that two different mills are getting the same results indicates to me that it is likely a strategy issue. I should also mention that we have tried different burs including what is recommended by Zahn (our reseller)

We have also done various other trouble shooting things such as calibrations and cleaning and greasing the poles that the milling part slides on (sorry for not knowing the technical terms here)

Anyways, any thoughts on what may be going on would be appreciated.

I wa going to say it is a calibration issue but the chipping at the margin combined with this line at one time my puck was not tight and secured enough and was slightly moving. Unscrewing the puck was a loose one and this is how we found out what the problem was . Just keep an eye on that.

Yesterday I posted That after trying all the usual maintenance, I ran a mill with the 5 axis auto inside and out. That has completely solved my problem, even going back to the 3+2 strategy.

I had the same problem, parting lines or transition lines. I saw this comment today and i tried it. It looks better using both 5axis. I can still see lines. I just put in a new spindle and spindle motor its on a 52d and dci and using Millbox.

I attached a picture, see how visible they are. It is more visible on bridges than single.

Do you think this is something related to software or strategies?

Im also contacting my reseller and cimssystem support.

I have had this problem over 2 years and have tried absolutely everything. Changed rails, spindels, tried different strategies, burs etc. These lines appeared also with new 52DCi. I got Imes 350i and the difference is massive so I am selling all my rolands.
