We almost almost finished configuring our cnc build at the makerspace I belong to.
Since the G540 has a charge pump, we thought we would take advantage of it. (We we're debating if we even need to since we don't think the bbb has the start issues that a pc parallel port does. My understanding is that the G540 needs a charge pump frequency of 10Khz It seems that config files that we started with was only setup with a 500hz servo-thread I suspect the servo thread is setup within the calls made at this line.. https://github.com/Workshop88/machinekit/blob/OptimizePru/configs/ARM/BeagleBone/RosettaBoneGecko/RosettaBoneGecko.hal#L43 ) Is this correct? We tried setting up a 10Khz thread here: https://github.com/Workshop88/machinekit/blob/OptimizePru/configs/ARM/BeagleBone/RosettaBoneGecko/RosettaBoneGecko.hal#L31 When we put a scope on the charge pump signal it was very erratic and the gecko faulted. (I was fine when it was on the servo thread but too slow) (When we had the charge pump hooked to the 500Hz servo thread we got a very nice signal. Are there any technical issues regarding the BBB that I'm not taking account?
