Howdy!

I've made some progress the last couple of days with the retrofit. Mainly around the control panel design.

I received a secondhand 27" ELO touchscreen in the post, which I got for an absolute steal. Yet to power it up, but it was sold as functioning and the drivers work on linux. The new control panel is based around this screen and the gmoccapy gui, with a handful on hardware controls I've deemed necessary from the Heidenhain. I'd also like the panel to rotate around to aid interaction while standing in front of the bed/doors. I've orientated the screen vertical, as it's bloody huge.

Attached are some screen grabs of the CAD model. It's designed to take the MX Cherry style switches. Looks like a few of you have used them and I'm a sucker for a "clicky" button. One MPG, e-stop, usb jack, all the usual suspects etc. Control enclosure is to be fabricated from 80x25x3mm aluminium channel for the perimeter frame and cnc routed 3mm sheet for the front and rear panels. I'll glue this together with the TIG and send it out with the next client job batch for powder. 

I also received a Delta 11kw VFD. Again, it was removed from a working machine and was considerably better value than a new one. Dug out a Omron encoder that was leftover from another project that never saw life. Planning to use this on the spindle.

Cheers,

J

Yes, the RS-422 is their smart serial connection between the 7i97T FPGA main board and 7i73 and 7i84 daughter boards. Since there is only one RS-422 configured standard on the 7i97T (on TB4), you can only connect one of those two cards, until you reflash the 7i97T to reconfigure some of the pins of the P2 expansion port to provide a second RS-422.

Glad you are enjoying my videos. It is fun to dick around with this stuff

Thanks for the clarification Mark.
Apologies on the slow reply, I've had an internet detox the last week! 

Do you need all new drives?

I thought only one broke.

Sorry Langdons, I've been away the last week and decided to take a breather from the internet.

By the looks of it yes, just one. However, given the likelihood of another dying in the future, I'd rather replace the whole bunch. The quotes to repair them are sky high and secondhand ones are almost as bad.
