Troubles to get started with SD240 Retrofit

Category: Turning

If you set x-index-enable high manually, does it get cleared if you jog the axis? 
(enough for one full turn of the encoder)

Beware, this may trigger a following error

Speed in jog use

Works for me. I use the same potentiometer for jog and feed rate (changes are immediate during jogging and running commands):

#*******************************************************************
# --- FEED/SPEED OVERRIDES BY PANEL POTENTIOMETERS ---
#*******************************************************************
# --- POTENTIOMETER FEED OVERRIDE ---
setp gmoccapy.jog.jog-velocity.analog-enable 1
setp gmoccapy.feed.feed-override.analog-enable 1
net rapid-override-enable => gmoccapy.rapid.rapid-override.analog-enable
net poti-feed-scaled => gmoccapy.jog.jog-velocity.direct-value
net poti-feed-scaled => gmoccapy.feed.feed-override.direct-value

I can set it high in HAL-show by pressing the SET button on the right side, but not by homing/tripping the switch.
Also with 1ms division I can not see the index rush by...

Jogging in Probe Basic

I was previously continually jogging by holding down the + or - buttons in Probe Basic. However now it only moves one step at a time. I’ve obviously made a change somewhere but don’t know where to look. 

Any ideas?

Thank you for your answer
I can change the speed with a potentiometer, but if I change it while the axes are moving, it doesn't take effect. I have to stop the axes, change the speed, and then move the axes again. What I want is to be able to change the speed while the axes are moving.

I'm going to run some tests this weekend.
To be honest, I'm having trouble understanding the purpose of the FF0, FF1, and FF2 terms. Are these offsets of the PID terms?

Are you saying you cannot set x-index-enable true in halshow?

hm2_7i80.0.encoder.00.input-index pin staying true may be OK as this just reflects its
polarity, and you are unlikely to catch the actual index with halscope because of its narrow width
(especially at 500 ms/division where halscope throws away most samples)

Unless you can set x-index-enable it will be difficult to diagnose

No, something is wrong.
the  hm2_7i80.0.encoder.00.input-index pin permanently stays true and
the  x-index-enable signal permanently stays false. The pictures show the state they are in and also when moving the axis by G1 F10 X 0 to 10 and back nothing changes
And the index-enable does not go high when the home switch trips (when homing)

There are pins to change jog speed using counts (eg for encoder) and for using analog value (eg for potentiometer):

I'm trying to execute an M100 from this toolchange subroutine, whithout M100 works. Here is the M100 and it works in MDI, what can cause the hang? 

#!/bin/bash
# M100 Orient Spindle (Homing function)
halcmd sets s-index-zero-for-ATC true
exit 0

Thank you Andy, but I can not gain access to the X-Motor or spindle- probably to the Z spindle and move the Z-axis, I will try. So jogging the X-axis slowly must do the job.

Alex, try
$ ethercat -p 2 download 0x6068 0 nnn
nn being the number you want to set. There is also an upload. Sometimes it is better to do it outside of linuxcnc.
Check for SDO index:subindex using $ "ethercat -p 2 sdos"

Max, did you try to claim it with "AliExpress Seller Protection"?

Philip, the manual says it can be done see snippet here
 
You should be able to add PDO 0x60ff to the SyncManager listing in the config, I think.
0x60ff is also in rxpdo 1703,1704,1705 so one of them should work. I guess.

isolcpus idiot's guide?

Category: General LinuxCNC Questions

To change isolcpus you edit /etc/default/grub as root

Something like:

xed admin:///etc/default/grub

 or

sudo xed /etc/default/grub

and then in the grub file change this line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To something like:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash isolcpus=3 idle=poll"

(3 assuming you have a 4 core CPU)

When you have saved your changes, you run:

sudo update-grub

and then reboot

Also with RealTek MACs it's likely that you will need to replace the normal RealTek
Ethernet driver with the DKMS version (search the forum for DKMS)

One additional step to improve Ethernet latency is to pin the Ethernet interrupt
to the last (real-time) CPU

To get an idea of Ethernet latency, you can run this command:

sudo chrt 99 ping -i .001 -q -c 60000 (card_ip_address)

This will run for 1 minute and then print statistics
 (card_ip_address) is the motions control cards IP address
