Arc Maintenance

Justmat · 2019-04-10T14:00:30.142Z

@tehn, a couple of my arc knobs have become a bit loose and wobbly. Is this something that I can tend to myself, or would it require sending my arc in?

first off I apologize for the trouble.

everything can be tuned with a 1/16" hex. remove the bottom enclosure then gently tighten the two screws of the loose knob. overtightening can bind up the action, if so just loosen and reset.

if you run into trouble I’m happy to get it fixed up.

No worries! That seems easy enough, I’ll give it a go later today.

I received a used Arc yesterday (2019 edition apparently) and I’m having a fair amount of wobble on two of the four knobs. I tried tightening the screws as mentioned above but they didn’t seem to go any tighter. The packing wasn’t terrific, so it could’ve been damaged in transit, but is there anything further I can try?

hey hey! sorry to hear about the trouble.

there’s an additional screw which affects stability. using your 1/16" hex:

remove the bottom
remove the two screws below the problem knob
tighten the center knob screw
reattach everything in reverse order

we also can provide grease, which typically helps fortify stability – just email help@monome.org to arrange either that or in-house reconditioning!

I had a loose one a while back and new grease fixed it right up.

Which grease can be used? Looking for something locally.

I’m about to go through the reconditioning process again but I’m wondering if the leftover grease I have has dried out, is that a possibility? It’s been stored in a mostly-airtight ziploc-style bag for a little over a year and starting to look a little like separated yogurt around the edges.

(The wobble has returned on two of four encoders, I think I might not have used enough grease in my first attempt and the problem may have been aggravated by some recent travel, despite my attempts to keep the arc safe.)

From an old email convo I have with @dani_derks it’s TAI / Nye Lubricants Fluorocarbon Gel 868VL and they don’t recommend using anything else. Unfortunately the stuff is $$$ and doesn’t seem available to purchase in small volumes.

correct! though we will absolutely drop some in a baggie through the mail for the cost of shipping (US or int’l). if anybody is in need of this, just email help@monome.org and we’ll get you set up

when this happens in the jar, we just have to mix it to reincorporate.
please let us know if this isn’t possible for your leftover quantity and we can get more sent out!

Thanks for the quick reply, I’m happy I was able to get this done today. Reincorporating the grease seems to have worked.
