AXBB-E 6 axis wiring
Posted: Sat May 08, 2021 10:21 amHi All,
I'm having some troubles getting additional axes running on the AXBB-E board.
I have a 5-axis router that I have allowed a 6th axis for future expansion.
controller box consists of an AXBB-E with 6x TB6600 drivers - Ethernet connection to an i5 8gb ram NUC running WIN10 pro.
24v PSU, 12v PSU, 5v PSU (all independent)
PC link to controller is flawless and all limit, estop and z-probe working fine.
I have all X,Y,Z,A axes running perfectly, however these are all running of the non-isolated outputs (port 1 / pins 09-16)
The B and C axes signal outputs are connected to pins 05-08 on the isolated side of port 1.
It is my understanding that these are isolated from the 5v0 on the non-isolated side, so I have bypassed the 5v0 on the AXBB-E board for these two axes and run them directly from the 5v0 side of the PSU.
I have also tried these wired back to the 5v- on the non-isolated side.
Currently, I cannot get any movement from any axes connected to the isolated side.
The kicker here is that I'm using mach3. I have other machines in my workshop running mach3 and for consistency, would like stick with it.
The port / pin allocation in mach3 settings are pretty straight forward and I believe I have them allocated properly.
At this stage, I feel this is a hardware wiring issue, rather than a software issue. Does anybody have a wiring diagram for connecting 5/6 axes to an AXBB-E?
That being said, any advice from anybody who has successful used MACH3 with an AXBB-E with more than 4 axes would be greatly appreciated!
Thanks,
Giffster
