Hi Tom,

Thank you very much. Please see the attached profile xml file.
Any advice will be really appreciated.

Best Regards,
Eric.

hello Eric,
in the XML you sent B-Axis is not enabled?
if enabled do not forget the Motor Tuning

i would set 10 steps/per 10000 velocity and 10000 accel, to make sure
b-axis will not slow down the other axis.

Hi Tom,

It is strange... I enabled the B-axis.
There are a few options for B-axis. I'm not sure which option was turned off.
I went to Plugin Control > CSMIOS (Config), and then tick the box for B-axis.
Is there anything else I should do?

Strangely, the Step Pin# and Dir Pin# for all axes were set to zero. Is it normal?

Best Regards,
Eric.

hello Eric,

Config -> Ports&Pins -> Motor Outputs -> enable B-axis

Pins will not matter because this is handled by the plugin.

Regards Tom

Hi Tom,

Yes, that was exactly how I activated the B-axis. Sorry for my confusion.
But, even when the B-axis was ticked in the Motor Outputs setting, in the xlm file the value for Motor 4 was still zero in the xlm file.
<Motor4Active>0</Motor4Active>
Interestingly, I could get the analog output well. However, the all motion stopped.

I'm trying to change the motor speed and acceleration values in the Motor Tuning menu.
I will let you know how it works.

Best Regards,
Eric.

Hi Tom,

B-axis still rotates very low. Here are the motor settings and G-code used.

X axis: steps per 101.823, velocity 4000.2, acceleration 200
Y axis: steps per 101.795, velocity 4000.2, acceleration 750
B axis: steps per 100, velocity 10002, acceleration 10000

hi,
if i run your test here with all axis in Zero it takes about 21s.

That is a really slow speed.
The linear speed (F300) should be 5 mm/sec.
Since the linear distance along X is only 4 mm, it should take only 1 sec?

I've removed the B... command and ran the code again.
The movement is much faster.
I don't quite understand what B-axis setting is wrong.

in G1 move all axis start and stop together

B-Axis has 97mm to go, so it is about 20s.

and the x-move is 30mm, you start from X0

Hi Tom,

Finally, I managed to solve the problem.
The critical thing was to use G93 command, which let the machine finish all axes movement in a specific time.
All working now... Thanks a lot for your help so far!!

Best Regards,
Eric.
