I purchased a "Sejin Staco Switch SKR-3620P PS/2 88 Key Washable Industrial Keyboard" on eBay for about $50 a couple of years ago. It doesn't have the best feel for touch typing and the trackpad is a little clumsy. For CNC operation I mostly use a touch screen so the less than ideal mouse is not a huge problem for me. The good news is that it is *COMPLETELY* resistant to swarf. When it gets covered with aluminum chips I just dust them off with 150psi air from the blow gun.
See https://www.stacosystems.com/product/m77760-military-rugged-duty-usb-keyboar d/ for a very similar keyboard. It is not cheap but certainly beats keys jamming from captured swarf. > -----Original Message----- > From: Gene Heskett [mailto:ghesk...@shentel.net] > Sent: Tuesday, July 31, 2018 12:39 PM > To: emc-users@lists.sourceforge.net > Subject: Re: [Emc-users] Possibly useful keyboards > > On Tuesday 31 July 2018 09:40:24 andy pugh wrote: > > > https://www.ebay.co.uk/itm/Denford-CNC-tutor- > panels/323324414862?hash= > >item4b47a30b8e:g:geAAAOSwKb1bN1hG > > Only 1 and not working. > > But a much bigger monitor/touch-screen could be handy around the mill. > Even a square keyed logitech K360 gets hung up with swarf entirely too > easily.
