Gmoccapy Toollength sensor routine stops sometimes

Category: General LinuxCNC Questions

Oh, apologies I was looking at the wrong move.

Maybe try this:
G53 X#1700 Y#1701        (Wechsel XY Position)
M6 T#<_selected_tool>
M66 E0 L0 (Stop read-ahead and wait for code execution to catch up)
(DEBUG, 1801: #1801 1802: #1802 )
G53 X#1801 Y#1802       (Taster Position)
G53 Z#1800                (Sichere Z Position)
M66 E0 L0 (Stop read-ahead and wait for code execution to catch up)

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

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?

Its more Hbot than corexy, but its more of a T bot, or t_t bot which forms an H shape

Sorry, I didn't understand the translation well, I don't speak English, in this case the remora doesn't support high pulse frequencies due to the limited hardware, does the ec 500 and ec300 have an input for high pulse frequency encoders? Or does it only allow you to make an extension module for the encoder? If so, what would this expansion module be like? Is there anything ready? and how would you add it? Sorry for the number of questions, I'm very interested in this project



It is supported, but refer to Murphys post, the limitation is in the board hardware.

My problem is now that if I jog with my keyboard and after i dont press anything sometimes the motors still do 1 or 2 steps. And i cant figure out why. Maybe someone has the same motion controller with linuxcnc or could help me?Thank you


It is related to the motor tuning setting in Remora/Linuxcnc
