I tried using two modes on the lathe spindle.

I want to be able to change the spindle speed mode to c-axis mode which can be changed by entering Mcode

Here is an example of my code:

#######################

net caxis-cc-step <= stepgen.2.up
net caxis-ccw-step <= stepgen.2.down

net mode-caxis => and2.10.in0 => and2.11.in0
net caxis-cc-step => and2.10.in1
net caxis-ccw-step => and2.11.in1
net caxis-cc-out and2.10.out => or2.6.in0
net caxis-ccw-out and2.11.out => or2.7.in0



net spindle-cw-step <= stepgen.4.up
net spindle-ccw-step <= stepgen.4.down

net mode-spindle => and2.12.in0 => and2.13.in0
net spindle-cw-step => and2.12.in1
net spindle-ccw-step => and2.13.in1
net sp-cc-out and2.12.out => or2.6.in1
net sp-ccw-out and2.13.out => or2.7.in1

net servo-cc or2.6.out => parport.0.pin-08-out
net servo-ccw or2.7.out => parport.0.pin-09-out

#######################

M198 code:
#!/bin/bash
halcmd sets mode-caxis True
halcmd sets mode-spindle False
exit 0


M199 code:
#!/bin/bash
halcmd sets mode-caxis False
halcmd sets mode-spindle True
exit 0

#######################

I have tried all the codes above. M-code works well, it can change the spindle mode to c-axis or c-axis to spindle mode. but the resulting signal is not perfect.

I assume that the stepgen signal cannot use and2 or or2 logic, so that the stepping signal is damaged?

Uhi, das ist ja süß... all in one.

Ja viel können muss das nicht... Es handelt sich um eine Drehmaschine...

Ich habe aktuell dieses Interface:

Mir geht es für das erste erst mal darum, mich mit diesem LinuxCNC zu befassen...

Ich hoffe es gibt hier sehr Hilfsbereite und schlaue Menschen in diesem Forum... ich selber kontruiere und baue Maschinen inkl. Elektrik aber bei Software ist es bei mir dann vorbei.

Tried this out but got following errors with large acceleration violations

Running the LinuxCNC logo:

 

How many degrees of backlash at the spindle?
 With this and the thread pitch, you could determine
the Z axis error caused by the backlash to see how serious it is.

I guess you could even make a hal backlash component for the
encoder position if need be. (create a deadzone on reversals)

Thank you for the feedback

If you wanted to use handwheels, consider Mesa over Ethercat.encoder/counter. Required Ethercat modules are expensive.

I have found it is better to use a matched pair motor/drive combo
I have had good luck with Rtelligent ECT drives matched to their closed loop steppers.
I could not get their ECT86 (NEMA34) drives working with NEMA23/24 motors.

hi
in my last test there was no following error on gcode running, the problem was the very low acceleration.
following errors appears on homing procedure

cia402 defines pins to set velocity and acceleration while homing. 0x6099 and 0x609a

Hi,

Can we test the cia-402 and shortcut linuxcnc pos-cmd to pos-feedback so
there is no ferror in linuxcnc that can trigger a motion stop? 
Or test it by hooking the cia-402 to a stepgen or pid without closed loop feedback. 
 

The only time this is necessary is during internal homing (if used). During homing, motion is happening that Linuxcnc does not know about so it generates a following error if this is not done.
In the drive, motion is measured in encoder pulses and in Linuxcnc uses device units
One of the other  things the cia402 component does is scale the encoder pulses to Linuxcnc device units (mm or inch)

It depends on the drive but many of them will have a SDO that tells the drive to use open loop or closed loop. There are some reasonably cost effective open loop Ethercat cia402 drives from Rtelligent and Leadshine. Both offer drives that can control two open loop stepper motors. The Rtelligent ECR60X2A is USD $60 each ex works (for 2 steppers). 

motor is 7.5kw so it has enough power machine is heavy 3tons knee mill
and gears are strong enough..
If something breaks will be the tap.

Looks like the board is at .10 and the PC should be .11

Can these settings pushed to master?
because with default configuration i have also the same problem...

hi there,

share photos of electronic which you have...

I have build profibus machine over ethercat and it works in the 2ms synchro ... I can help you if there will be avaible stuff and time

AX5xxx from beckhoff is SoE and it can be pain to create custom .xml which should be editable out of Sachas own .xml files...

I can recommend you ethercat stuff ... S120 over drivecliq is very powerfull tool with 31.25us bus cycle but prices are out of any small shop budget ..

regards

Yes Cakeslob it's for my mill. Bought a cheap 24" touchscreen from Amazon and got carried away testing it lol Static IP address, is it 10.10.10.10 or 10.10.10.11  for the board ?

murphy, is this a new linuxcnc and remora install?
