LinuxCNC gcode hangs on M63 "main loop took x seconds"

Category: General LinuxCNC Questions

Not sure. You have another subroutine call 'retract_pocket' after the G91 move in question. Maybe try stopping the read ahead before it ingests that and enter a debug line to make sure the Z and F word are what you expect them to be:
; Deactivate tool release to grab tool
 M63 P17
(DEBUG, Z-#<z_jump>  F#<z_jump_speed>)
 G91 G1 Z[-#<z_jump>] F[#<z_jump_speed>]
 M66 E0 L0 (queuebuster to stop read ahead here)
 ; Retract pocket and move to X offset
 o<retract_pocket> call [#<selected_tool>]

This are terminal connections on VFD: 

 
 

So proper solution would be to take +10V Reference output on VFD, connect it to SPINDLE+ on 7i78 and Local voltage speed reference input (A1) on VFD and connect it with SPINDLE- on 7i78?
Any need to connect also 0V COMMON from VFD?

Ohmic sensing has been working reliably for the past few days. I would not want to be without it. Makes probing so much faster and more reliable.

So my fifth stepper motor driver arrived and I will soon take the plunge to add a rotational axis.

So I read linuxcnc can only handle 3 axis trajectory planning.

But I need a fourth axis to place the torch above the center of the pipe.
I guess this can be done during homing.

Should I make a new configuration with the rotation axis being the X axis. Change the current X axis to the A axis in order to move the torch to the center of the rotation table?
