Improved Keyboard????
Improved Keyboard????
Is there any ongoing effort to improve the keyboard? There are plenty of complaints on this forum about its problems. I have had my DM42 for about a year and I have resorted to going back to my HP 32S for most calculator use. I really like the DM42, still use it for the custom programs I put in, but the keyboard flakiness has been too much. I would love to get another DM42 if I knew it had a decent keyboard. But I couldn't recommend anyone else get one like I have.
Re: Improved Keyboard????
The problem has been identified. It seems the metal sheets from which the metal domes were stamped weren't cleaned properly.
An oil film prevents reliable contact. The domes and the contact area on the PCB can be cleaned, which significantly improves the reliability.
We encourage anybody having such issues to do so, but of course this is not what customers should need to do.
We're working with a new supplier for new foils with the metal domes. Once available replacement foils can be obtained.

May I suggest an "how-to" video for those who want to try to clean the domes?Michael wrote: ↑Thu Feb 14, 2019 5:54 amThe problem has been identified. It seems the metal sheets from which the metal domes were stamped weren't cleaned properly.

As for myself, only the "on/exit" key have problem, but as akaTB suggests; a howto-vid would be highly appreciated

Re: Improved Keyboard????
Are we talking about keys that don't reliably register, or debouncing issues with unwanted repeats? I suffer from the former, but have never seen the latter.
Will someone tell us when the replacement foils are available and how to request one, please? thank you.

Re: Improved Keyboard????
Unfortunately it'll take at least a month or two for the new foils to be finished.
We'll post the availability and how to get them here in the forum.

An unreliable contact can cause either phenomenon.
There are only 10 kinds of people in the world: those who understand binary and those who do not.

Thank you. Good to know you are working on it.
