10 Axis stepgen Mcode

Unknown parameter 'num_extrajoints=1'

This parameter is only available when using
the experimental branch dgarr/motion_extrajoints

It is not compatible with hostmot2? or my configs?

I am using 2.8 version. How can I control plus one motor?
No need to interpolated motion, and I have one Stepgen available.

I have deleted the 'num_extrajoints' part.

How can I declare more than 9 joints in the .ini file? needs other versions?

What is the changes in the .ini file to consider one more joint and to be homed?

A little bit confused,

Thanks,
André

Hello,

After many tries I can make a move in my tenth axis motor using M-Codes.

Can you help me to build a homing sequence?

I am using a stepgen with a position control, after homing all the main axis activate a M-Code which leads to a movement in my 10th axis.

I am having trouble to stop the motion. I want to configure a input to be active in rising edge and not in falling

Hello,

After many tries I can make a move in my tenth axis motor using M-Codes.

I am using a stepgen with a position control, after homing all the main axis activate a M-Code which leads to a movement in my 10th axis.

I have connected a homing sensor to an input:
net 9-home => hm2.5i25.0.7i76.0.0.input-06 then associated a halui command net 9-home halui.mdi-command-04 (M110)

After Homing the XYZABCUVW I add an and2 logic to activate a halui.mdi-command-00 (M120) to make a motion in my 10th axis
M120:
halcmd sets 9-enable TRUE #enable on
halcmd setp hm2_5i25.0.stepgen.09.maxvel 0.1 #set vel
halcmd sets 9-pos-cmd 3 #set position

Then when hitting the home sensor active the M110
M110:
halcmd sets 9-enable FALSE #Stop the motion
halcmd setp hm2_5i25.0.stepgen.09-position-fb 0 # I CANT PUT THAT VALUE INTO 0
halcmd unlinkp hm2.5i25.0.7i76.0.0.input-06
halcmd sets 9-enable TRUE #enable on
halcmd setp hm2_5i25.0.stepgen.09.maxvel 0.05 #set vel
halcmd sets 9-pos-cmd -0.1 #set position


The problem is when I hit the sensor i cant put the position in 0. say that pin is not writable. There are any way to do that? Or can I have latch or something working like home?

Also I want to configure a input to be active in rising edge and not in falling

Much thanks in advance

Hello andypugh,

I am using PREEMPT RT debian 4.9 the version of linuxcnc is 2.8

I was able to invert the input, expected what I want to do, and I have managed to control my extra motor via M code
I am using one M code to go up and another one to go down. I've got a limit switch when it turns on stop the motion on my extra motor and connect to a Mcode if needed call to stop motion.
