Sven,
Too bad, I am ocean hop away in LA. Do you have a BOM for your router build?
Are you building the injection molder from scratch or retrofitting an
existing one?
thanks,
John

Ha ha, we went OT on the OT. :)
The new build is from scratch. Electro driven knee press mechanics, 30-35
ton clamping force but not a very large shot size. Really small floor area
is used, the machine is vertical.
My real machine can be tilted vertical but that is not to make a smaller

HI there
going from memory here but you need two volages to the drvie so need a
power supply thats all, as control does that right now from its power supply
then feed the tachos back into the drive, on the M0 they went into the
control card, then back out that was all, so was a case of moving

Looks like you should get a nice fit with 14 points.

I just looked at the 7i80 and it looks like the holes are symmetrical so
you could mount it any way round I think.

It was noisy and dithered a lot. The Arduino has to measure 2 voltages
The 7I80, and 7I49 are symmetrical, they are both 4 x 4, but the 7I70
and 7I71 are not, and those are the more critical ones to have
orientated this way. 48 number 16 MTW wires routed to each of these
boards would look like crap with the board 90 degrees off.

Yes, a more powerful MCU would be better, and it so happens that Mesa
and Pico sell exactly that all ready to go.
Why will nobody believe me when I say that my experiment was rubbish?
Because Arduinos are so cute.

MTW is really difficult to route. I've been using 18 gauge UL1007 300
volt stranded hook up wire for that. Its a dream to use compared to MTW.
Once you use it, you will never use MTW for that again.I order it

Ah, I was under the impression that they are all the same size.
Yes I agree that would not look very good. I use a multi strand 0.8mm
sqr wire with bootlace on every wire. Then it is not that crowded around
the connectors.
