Hello everyone,
first of all I don't know if I'm in the right place in the frum, but if I need to move my message please let me know.
Like you, I am in the process of retrofitting my 5-axis CNC type XYZBC.
In fact, having important torque reducers on the B&C axes I want to add encoders directly on these two axes. For this, I have started to buy a 7i96s where only one encoder is available but a daughter board can be added like a 7I85.
I've started to connect the system under linuxcnc 2.9.3, and I can't synchronize the scale between the Axis display and the actual position of my encoder.
my encoder is 1000 pulses/hole in quadrature, which gives 4000 pulses per revolution. With variables SCALE_ENCODEUR = 11.11 I manage to synchronize the display & the actual position of my axis; unfortunately my “joint” doesn't follow; I need at least a value of 3000 pulses/hole to no longer have this “joint tracking error”. And even with this value, the motor remains very reactive to the slightest movement of my encoder. Of course, the display no longer corresponds (since there's only the value of 11.11 to synchronize the display and the position of my axis).
I've been struggling for two months just to get this setting right.
Does anyone have an idea for my problem?
Thanks in advance for your help
