Just standard linuxcnc settings. You have Velocity and Accelerations settings for every axis in the ini file. Adjust them to your liking.

I'm still working on it. At the moment it is only partially useable. At the moment I am working on ensuring that the contour is implemented correctly. Especially with regard to circular arches. Thread already looks good. The goal is that 100% can be done on the machine. After I have implemented this with the contour, the goal is that a correction is included, depending on which tool is chosen. Means that the cutting geometry is included in the movement depending on which tool is chosen. If possible, the information should come from the Tool.db. In addition, a warning if the chipping with the tool is not possible. I can't say how quickly I can do it, but I'll try until I have a working solution. Anyone who has ever worked on Siemens controllers should certainly get along with the panel, because my experience with the machines certainly shows similarities.

Hi,
thanks for the answer!
To get the 7i92T working I need at least a "standard" lpt breakoutboard, right? That would be for the steppers. What would I need for a 0-10V signal for the spindle? Can I plug in glass "sensor" into it? (I would not really need it, never had any step losses with my other machine).
Well yes you always have to double check what the KI says, but for programming it helps alot
regards Han

Good point Rod, I will do so.

Hi all,I'm experiencing an issue with my EtherCAT drive. When I try to move any axis through LinuxCNC, the motion is noticeably slower compared to using the drive's own software.I've attached two videos for comparison:

• LinuxCNC control
• AutomationSuite control
  
  The motors also seem quite loud in LinuxCNC.Any suggestions or insights would be greatly appreciated.
  
  Many thanks,
  Lorenzo

I was able to find the manual and some info´about the alarm. Even if there were very few clues in the post
 
Then you can tryor if you have an old lcec version and syncToRefClock isn't recognized: refClockSyncCycles="-1000"

Check the lcec.0.pll-reset-count variable that it stays on single digit. Read at least one full page here github.com/linuxcnc-ethercat/linuxcnc-et...istributed-clocks.md

Good. Has happened before. A total reset after eeprom update is usually a good idea.
I normally upload firmware on the fly, even when connected to linuxcnc. Much less sensitive.

And what does the last lines in "sudo dmesg" say?
It is the drive that is unhappy, but hopefully the ethercat master tells why it won't download data to an SDO.
Or give another clue.

Yes, 67108864 is Encoder count per round.
The problem is "Alarm A12 (EtherCAT Output Syncronization Error) "

A support person said,
"As long as A12 occurs, servo amp can't anser properly."

strange, i unplug everything and replug and itw works in linuxcnc too
very happy about this
i will continue to see what can I achieve
thanks again !!!

I uploaded the github

Stick with Mesa, loads of info, it works without issues, they've been around for ages. Support is fantastic. A 7i92T gives you 2 lpt like interfaces. So 34 io pins, can be expanded via SmartSerial cards to get even more io. Mesa drivers are part of the Linuxcnc source code, so you know they will always be supported.

Oh BTW chatgpt has given so much useless info regarding Linuxcnc it's gone past be a joke to a complete waste of time.

According to the manual section 6, it shows that I need to supply 5-24v DC to that circuit. Can I just use my 24v field power for this?

No, the output can switch 5V to 24V signals but should not be directly connected to a power source for sinking (NPN) operation

The ALM output would wire directly to a 7I96S input as shown in my table.

The drives 5V/24V switch only affects inputs (PUL,DIR,ENA)

Note that the ENA input is actually a  DISABLE input so not really of much use unless you change it's polarity.
(because the drive would be enabled if there is no controller power which is a bit crazy)
This likely requires the use of the (windows) software setup utility for the drive. Similarly, the ALM outputs cannot be
paralled unless re-programmed to be ON for alarm rather than the default OFF for alarm, They could possible be connected
in series instead using the default (OFF for alarm) setting

To use a step/dir pin for ENA, you set the number of stepgens to < 5, freeing up the GPIO pins that connect to say stepgen3 or 4
you then use the GPIO pins in hal to control the output state of these pins.

 

I note you use the qtpy abstraction layer. This is not pulled in for our linuxcnc package, so could trip some people up. I would suggest adding a descriptive warning to the terminal if the module is not found.

7i92t_benezanx2d.bin firmware will at least have the first 4 stepgen pinouts correct
so that will get you a bit further.

To get the stepcraft configuration fully working may require a  new firmware configuration,
at least to get the PWMgen on the correct pin. Do you have a list of all DB25 pin functions?

John,

Yes it is the UPWM board. It is driving your pwm servo drives. The CMOS battery did die at one point but the parallel port is set up in epp mode. I am not sure why it is doing this. If you have any troubleshooting tips I would be glad to hear them. Could the eeprom be bad?
