Has anyone considered using toothed idler pullies with the same pitch as the drive Belts? It may reduce mechanical noise as the belt teeth would fit in better than using smooth pullies which could cause sub or hypersonic vibrations.
The scope pictures are great but the piezo signal is clamped by the 2 input diodes to ca 0.7+ - Vdc by D1 and D2 to the input of the differentiator IC1a.

Cool it's not the money its the space might invest in some sort of PC based scope.

Yes, the shielded cabloes appear to work well, don't have a scope to do anything . This is eating into my beer budget. I've replaced the stock motor /gear train with a Tevo Titan clone with a Nema17 stepper and saved over 500g of weight on the gantry. Need to adjust the driver as motor got very hot in a 1hr run. The B W uses one motor to turn 2 lead screws with a belt. Don't have specs as to what max current istate for the nema17. I'm sorely tempted to get that rigol ds1054 it's 50 Mhz, 4 channel, excellent specs,very Impressed!

Okay so I finally mounted a titan aero direct to my x carriage via the motor bolts. But where am I going to put the piezo sensor?
[attachment 97949 20170909_095046.jpg]
Between the motor and carriage of course!
See it in action here [youtu.be]
The part is on thingiverse, it works but I have not done much testing yet, but please feel free to try it. I suspect it (or a variant) might be useful in variety of other locations also.

Hi kjcjr89,
The only thing I can obviously see in your smoothie config (and I must admit I only played with smoothie for a few months, I am not really an expert)
Is that I have defined
# optional Z probe
zprobe.enable true # set to true to enable a zprobe
zprobe.probe_pin 1.29!^ # pin probe is attached to if NC remove the !
zprobe.slow_feedrate 5 # mm/sec probe feed rate
zprobe.debounce_ms 1 # set if noisy
zprobe.fast_feedrate 50 # move feedrate mm/sec
zprobe.probe_height 5 # how much above bed to start probe
I have ! left in as normally the unit works Normally Open.
That might be all it is. I was using a re-arm so same pins I think as for Azteeg.
I found a low debounce seemed to help.
