Swash gen 8 cutback issues

[Jesse Phillips]

So I have a brand new gen 8 cutback that is doing erratic things and I beleive I have narrowed it down the the needle bar tensioner. The machine ran great for about 5 hours of tattooing when I first got it but then started to erratically slow and speed up and spit a little. I replaced the o rings on the tension wheel and it still seems to do random things. I tried using rubber bands on it and it runs much faster, smoother and quieter this way but the consistency of the hit still seems to vary a little bit. I am using folded paper towel grommits, brand new rca cord and trouble shot with 3 different power supplies. Any insight would be greatly appreciated.
I should also note that this machine is a replacement of one that was doing all of the above but even worse... and when I returned that one to swash they said nothing was wrong with it but sent me a new one after some protest on my behalf. Im shaking my head here thinking maybe this is just how they run?

hey bro…not sure if it helps……but there is thread already somewhere on the forum about this issue…
and i have the same issues with a compact….i fucking love the machine but i still can't figure out why at the most random times, it runs sporadic….like fluctuates in speed…really weird

i would say its the motor ...i have bought the first gen8 and compact as its come first in the sale ,all very nice -so i would say any have change and the parts all the same so i would say any have change in the motor -or have you try a different rca ? what powersupply to you use

I have to say that these machines are really picky about RCA cords. A bad connection makes it run like this.

my tensioner broke - they sent me a replacement i never put it on. and i have never had any issue with mine

[Jesse Phillips]

Brand new Bishop rca. Powered with cx2-g2, cx1-g2, eikon ems-200.

I would still check another cable.

If the cable is the issue its easier than sending it in for a new motor

Ive used about 5 different rca's with it.
Today I took the stay up spring out and just used rubber bands instead of the tensioner and it ran flawlessly.
I think that the added resistance of the spring and the friction of the tensioner causes the irregularities.

maybe its possible the bearing is not right -so you get some tension on the motor - with the rubberbands its the tension maybe less . Try to adding oel to the bearing or replace it

Yeah man, the bearing is oiled. Im going to order a pack of bearings from oust really soon here though.
