This is awesome, Josh! Thanks for sharing so others can give this a try. I did want to drop a line and mention that dismounting the B axis circuit board (like shown around 1:29) will invalidate the factory B axis calibration, requiring the machine to come back to our facility for a recalibration if the user wants the machine to be as accurate as it was when it left the factory. So, it is much better if the probe can be plugged in without dismounting the B axis circuit board, which should be possible from what I could see in the video.
Thanks for the heads up! I disassembled it to poke around and figure out how to integrate, but you are correct that no one using the probe would need to dismantle the B axis.
Hi Josh, I have your probe and its excellent. Did you ever figure a way of using it with the Probe functionality in Fusion 360? It looks like the functionality would need to be added to the Pocket NC post processor to work.
For me it was worth it, since it has a much higher MRR in aluminum. However, it only has decent torque at very high RPM, so the V2-10 might be better if you need high torque at RPMs closer to 10k, or if you are more cost sensitive.
Is that probe using a three-legged interruptor/spider on the inside? My experience is that the lobes from those mechanics end up being the limiting factor, rather than the manual adjustment. Then again, turning the screws to 2 um (less than one "tenth") is boss, no matter where you do it :-) Also, much nicer and generally more repeatable than doing it manually! I wouldn't want to lose the probe I have on my 440. Very worthwhile upgrade.
Yes, it has three rods radiating from a central column, each touching a pair of contactors. The manual adjustment is definitely not the limiting factor. In practice the actual probing is only repeatable to maybe 5-10um or so. The spec for the probe is 3um repeatability, but the PocketNC steppers are in that range as well and contribute some.
@@awesjosh also, for lower cost items, specs are generally "best achievable" not necessary "guaranteed under adverse conditions" :-) Anyway, looks to be working great. Nice add!
