5 axis CNC Router/3d printer

Hi Tom, yes the Off button does trigger the M05. For some reason I thought the
the DAC value should also go to zero if the Off button was triggered. Long as the
outputs go to 0 then yes spindle will stop in either direction.
Is there a way to configure a spindle override slider to control spindle speed while
a Gcode program is running?

Hi George,

The one on the Screen isn't working?

[George Butty]

Hi Tom, I must be missing something because all I have on the 5 axis custom screen I am running is
a rapid slider and a feed rate slider no spindle speed slider.

Tom, sorry for being dumb again. I found it.

HI Tom, looking to set up a homing operation for my machine. I would like to have a home button on the
KmotionCNC screen and activate the homing program. I would be using the SimpleHome3 axis.c program sample
and set it up to home my 5axis. Not sure how to connect the home button in KmotionCNC to activate the homing program.
I am assuming the homing program would have to be place in the int.c startup program. Any insight would be appreciated .
Thanks
George

Hi George,

Like this.

Thanks Tom, I think this should do the trick.

Hi Tom, I had my B Axis running in the wrong rotation direction. It was not following the righthand run and the
machine would go the wrong direction based on the cad data I sent to the machine. I reversed the rotation of the B Axis
and now its following the Right Hand rule but now the RTCP is not going in the right direction. The X Axis is going in
the wrong direction to to make the RTCP compensations in the X Axis. Its moving away from center not staying on center.
How can that be reversed without effecting the Right Hand rule.

Thanks
George

Hi George,

I'd guess that you could add a negative sign in the Kinematics. Such as change:

Code: Select all

	Rotate3(0, 0, 0, m_MotionParams.TCP_X, m_MotionParams.TCP_Y, (m_MotionParams.TCP_Z + PivotToChuckLength), 0, b, c, &TCP_Rotated_x, &TCP_Rotated_y, &TCP_Rotated_z);
	

to:

Code: Select all

	Rotate3(0, 0, 0, m_MotionParams.TCP_X, m_MotionParams.TCP_Y, (m_MotionParams.TCP_Z + PivotToChuckLength), 0, -b, c, &TCP_Rotated_x, &TCP_Rotated_y, &TCP_Rotated_z);
	

Are you still using the standard Kinematics5AxisGimbalCB? Strange that that would need to be changed. Are you sure you don't have something else reversed? ie the X axis? A common mistake is to think moving the Table to the right is +X. But that is like moving the tool to the left.

Hi Tom, my machine runs all axis in the upper gantry. I don't have a moving bed so I think that is what
is causing things to go reverse. I am still running Kinematics5AxisGimbalCB but I am assuming that this file
runs a table in the +- X direction. From what I can understand from the change you recommend that will reverse
the RTCP B rotation. Is this correct?
