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

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!!!

It moves!!!!!!!!!!!!!!!!!!!!!!!!
It's alive...............:yahoo::victorious::beer::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 :whistle:

Re: It moves!!!!!!!!!!!!!!!!!!!!!!!!
Well done Neal it's always nice when it moves the first time.:thumsup:
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
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......

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

Tomorrow is wiring up the limit switches....and home switches...

Sounds very sweet too! Given that you are also running at around 70V it must be down to the digital AM882 stepper drivers ? - mine are DQ860MA on 1600 microsteps but still have a hint of roughness when running.
Bit worried about your 5 minute e-stop trip problem - something getting warm?

Cheers!! I'm not too sure what it is, could be I have the Nema34 drive configured wrong, could be an earth problem, could be my E-stop circuit....I'll try isolating one thing at a time tomorrow and see :)
