Rupes mark ii 15 stalling badly

**ZiggyPopp** · 07-30-2016, 11:15 PM

Forgot to mention that I use the smaller backing plate on my Rupes 21. I switch to the larger plate for hoods.

I'm not having stalling issues on my 21 MKII? I'm not saying it can't stall, it will on certain curves but a slight turn of the wrist to adjust angle coupled to change in pressure and machine speed and its spinning again. Reading the OP's intial post where it stalls for no reason on a flat panel is of some concern as my 15 MKI doesn't do that either. Can the OP take a video?

I thik you just not giving them enough time to work with it. You can find a video of Mike Phillips and rupes on youtube, see how can he work it through the curved without any problem.

I never have any problem of pad stalling from day 1 until now. I believed that sunce you just migrate from Rotary to Rupes, many of incompatible habit are playing with you. Come on practice more bros.

Or... buy a 3401 and have a machine that's built better, corrects faster, and won't ever bog down no matter what the circumstance.

there's a reason (actually a few) that it's been around as long as it has...

My Rupes corrects faster than my 3401 with far less effort.

This is another option.

You may find that the long throw just isn't for you, and you need something with serious muscle, this is the way to go. You can really lay into the 3401, and it will not stop spinning. You can finesse the 3401, and run into a curve or contour and it will not stop spinning.

It's another really well built machine, like the Rupes, and in my experience runs very smooth - the machine itself.

As much as I liked my 3401, my PC was kicking it's behind removing heavy swirls and scratches. I'm talking one set of passes vs two all things being equal. The pad on the PC spun faster.

Maybe I just got good at using the PC?

The 3401 had a nicer "ride" though. Also, the 3401 was awesome at removing heavy oxidation.

It also excelled at working in cleaner waxes, and applying sealants because I could use a lower speed, and the pad kept moving. I'd cut and polish with the 7424xp, and apply sealant with the 3401 on occasion.. Doesn't make sense on paper, but it did on the job.

I appreciate all the response I have gotten. I thought I would get eaten alive but it has been good.
So here is where I am with my black M3.
I used Rupes blue/blue and green/green and yellow/yellow and white/white and Carpro reflect/yellow rupes. Rupes yellow/yellow is really outstanding but Carpro reflect is the best polish I have ever used. No fillers and it feels like a wax when wiped.
So as you can see from all the steps I have taken that I should be up to speed with the Rupes machine.
Yes I prime the pads as Rupes recommends.
I use zero pressure.
I have used every arm speed from super slow to super fast.
I have tried all RPM ranges mainly focused on 3 since that is what is recommended.
As I was applying sealant with machine it rarely rotated which really didnt matter to me since I wasnt doing correction but I would think it would rotate very easy and with zero pressure and keeping pad level.
Someone made a comment about me using a rotary and now using a DA. I also use a PC7424 and moved to the Rupes to cut down on vibration.
I dont think there is an issue with the machine and I think I have pretty good detailing skills but I cant figure this out.
Corey with Carpro has offered to help. There has to be a simple fix. Positive advice is welcome.
