Comments sought on new build: A CNC Router for RC Gliders and Planes

what is the point in chopping a perfectly good cable and then putting a join in it. ..Clive

Well to start with the router will be floor mounted until I make the frame for it to live in vertically (at the rate I'm going that'll be months...)....so I was thinking to save having cables longer than I need dangling everywhere until it's finally sited I'd have a JB and when it's in its final position adjust the cables to suit....

Ah I now remember you are going to mount it vertical. But you will still have to have the continuity of the screens in the JB. ..Clive

Just putting the other related in and looking at the wiring....ive underestimated the number of 24v connections I need...having to put some more on the DIN rail now.....



Just put the Z axis front back on to see where the limit points are to be...

[njhussey]

Running out of room!!!!!!!!!!!

Just managed to squeeze in a timer relay for cutting the power to the spindle (after the stop signal has been sent to the VFD!!) in the case if an E-stop.

Hope there's nothing else I need to fit in!!!

[njhussey]

It's alive...............:toot : well the Z axis anyway!!

Jogged it up and down and it moves, need to do the autotuning thingamy bob on the AM882 drivers for the current but it's working.....only took 5 bloody years

[Clive S]

Well done Neal it's always nice when it moves the first time.

[njhussey]

Cheers Clive, got the Y axis moving now and did the flick of Jumper 4 on the AM882 driver thingy to tune the steppers, now they don't whistle....now for the X axis......

[njhussey]

Oh, put an "OH SHITTTTTTT..." button on the router end where the pc is at the moment....want to be able to hit it if it all goes pear shaped, especially as I've no limit switches at the moment!!!

Just wait until it's doing 15m/min down the table towards you

[njhussey]

Well all 3 axis are moving now, I need to check the alarm circuit and all settings on the drivers and in Mach as it trips and Estops after about 5 mins whether running or not....

Vid of all 3 axis running...
