Trouble with Cia402 drive configuration

Category: EtherCAT

It also gives the following error when I press the home button:
"emc/task/taskintf.cc 976: Error on joint 0, command number 74"
if that helps at all...

Trouble with Cia402 drive configuration

Category: EtherCAT

I made sure that they agree.

Do you know what
[69236.509163] EtherCAT 0: Slave states on main device: PREOP, OP.
[69240.307732] EtherCAT ERROR 0-3: Failed to set SAFEOP state, slave refused state change (PREOP + ERROR).
[69240.309731] EtherCAT ERROR 0-3: AL status message 0x001E: "Invalid input configuration".
[69240.311730] EtherCAT 0-3: Acknowledged state PREOP.

"(PREOP + ERROR) could be caused by? or "Invalid input configuration"?

Also, did you take a look at the .hal and .ini file? There are a few things in the .hal file that I don't know the purpose of, yet LinuxCNC doesn't run without them, so I'd appreciate an explanation of why they're necessary-if you're willing.

Setting up kinematics for my Ballscrew articulated B-axis

Category: Basic Configuration

Personally I would suggest tp use the .comp format:

linuxcnc.org/docs/2.9/html/man/man9/userkins.9.html

But regardless,
Forward kinematic uses the joint positions to calculate the cartesian coordinate positions 
Inverse kinematic uses the cartesian coordinate positions (ie the position commands of the motion planner) to calculate the joint positions (ie basically the commands that get sent to your motor drives)

One needs to be the mathematical inverse of the other (otherwise the values will run off and you will get limit violation errors)
