Hi folks. I’ve been following the zynthian project for a few years and I’m excited to have finally purchased and built the v5 kit.
All seems to be working as expected except that my buttons seem quite unresponsive. Sometimes they take many presses to register or need to be pushed at a specific angle or I need to push and then wiggle them around, etc.
I watched a youtube video of a zynth v5 and it looked quite snappy and responsive – not at all like what I’m experiencing. My encoders and touch screen work smoothly and the UI responds fast to those input methods.
I just took apart the enclosure, took another look at the buttons and pcb and nothing looks off to my untrained eye. I made sure to reseat the securing/orientation nubs in the 8 holes on the pcb and put it all back together. It seems a touch better now, but it’s still annoying and difficult to use the buttons.
Any tips or ideas to improve their performance?
Thanks and thanks for all the amazing and hard work that has gone into this project.
hi @aaron.oz - This post might give you some info-ideas:
You really shouldn’t need it yet - maybe you got a marginal silicone pad or your control board has gotten oxidized. The traces under the pad buttons should be nice and shiny. You could check if the pad buttons are conductive as they should be with an ohm-meter AKA DMM - Digital MultiMeter. I don’t know what’s normal - I’d guess under 5 ohms.
The new control board and buttons arrived today. Took 15min to swap them in and the zynthian is snappy and responsive now. Thanks again for the prompt replacement parts.
It looks like a faulty control board too. Now we are out-of-stock, so i can’t send you a replacement for the control board, but as soon as we receive the new batch, i will ship one to you. Please, don’t hesitate to ask me for it once we start selling V5.1 again.
Just FYI for new users just as myself:
This type of switch assembly can be a bit stiff in the beginning. After a few days of use it’s already much better. At least in my experience. It’s common - I have seen this on other gear as well.
