Small test



Calibration :

Thanks for the clarification. I'll provide feedback once I implemented the changes.

Hello,

thanks for the help... But nothing is working at the moment. :-D 

The best thing to do with worked... except that the card always restarted. But with the configuration the process data exchange worked anyway.

Maybe I don't quite understand this.
The operating mode of the EL6731 “DP (Equidistant / no GC)” is correct, isn't it?
That also changes to
I have now deactivated the FoE and AoE. I really don't need that now.

The slaves seem to remain offline and no data exchange.

How can I understand this?

Your config is missing of the DC configuration adn SDO datas cofig too

What have I forgotten?

Hello,
it looks like halui.spindle.0.override.direct-value is broken
I've tested feed override, max velocity an rapid override and it works correctly; it is only broken on SSO

method :
set override.direct-value to 1
set scale to 0.1
set counts to 5

works nicely except for spindle override

I'm using 2.9.4


 

According to my handbook the t3d 20a has encoder output on the db connection. 

I can upload the handbook, too large

TBH I used Deepseek on this one (and didn't filter out the 2-7 error), but I'm glad it helped you. The idle=mwait instead of poll seems to lower the temperature without much impact on the performance. Now the latency is good you could also try to only isolate the last core (so replace each 2-5 with 5), if the latency will be the same you'll have a much better responsive system.

Written well, Thank you for your effort David
So much valuable information about The Maho 700c
I need to read this carefully
Thanks again

You might want to start by looking at the documentation:

Seems it's max power output is 2.2kW and apparently does not provide a command interface that is compatible with Mach3:

No double posting.

Hi All,

This is the file mesact generated. I change the "channel 4" to channel "1" manually, and it loads to linuxcnc. I'll be wiring the 7i77 to the servo drives to test if the servo drives will respond to the jog commands. Wish me luck.

Regards,
Kelvin

I have a Kuka kr200 robot and its motors are brake motors between 1.5~kw and 4.5kw. My robot does not have its own board. I want to make it with STMBL. I need a guide. Probably via Mach3.

sounds like a synch or queuebuster command to stop the interpreter read ahead. As an example M66 will do this

There is a sim config that uses a python remap to create a custom Gcode:
github.com/LinuxCNC/linuxcnc/tree/master...remap/stop-lookahead

I have exactly the same right now. Mesa7i96s driving a Leadshine EM780S which drives an Omron Nema34 Stepper. At speeds above 200mm/min everything is smooth but below this speed the turning is very rough, particular when I edge it slowly with the handwheel. The Leadshine driver is currently set to x256 but I tried every setting from x16 up to x256.
Step length and -space is set to 3000, the Leadshine driver specifies >2µs.
Why would this only occur at low speeds, Steps missing or to high accelleration etc only occurs at higher speeds.

Hi Chris,
Nice to know there is another like mine in NZ. You've probably gathered I'm from NZ, but I live in Sydney NSW.
The controller on your machine is probably an old Philips one. It's probably not worth wasting time on. Better to go with  Mark's effort using LinuxCNC.
Mechanically, and some electrical I can help with.
If it is like mine then the hydraulic pump runs completely by itself. No controller involved. As soon as you power up the machine you should hear it growl.
I've attached a photo of mine and a cobbled up .doc of a Hawe brochure with the data values for mine added. On mine it's running on 415 VAC. NZ and Australia use exactly the same standards.
Since it's 3 phase it needs a contactor. In my case 3K1. A very big Siemens contactor for such a small device. I think I've put my power schematic up a way back in this thread. The wiring comes directly from the Maho's main isolator switch, then through a motor starter breaker 3Q1 and then 3K1. That is the complete power wiring.
If you look at the photo I've attached you will see the hydraulic unit on mine. It's in the rear cabinet bottom door. In the photo it is half out of the cabinet so I could work on it. The 3 things on top are hydraulic solenoids. The left unclamps my rotary table. The center one isn't used and the right one with the 5Y1 tag unclamps both Z and Y spindles simultaneously. Unfortunately the pressure switch, 5K1, that operates the pump I'd removed so I could get it where it is. The pressure switch screws onto the fitting sticking up at the rear. The fitting also has a stopper plug tee'd on for  a pressure gauge if you want. The pump simply runs when the pressure switch closes. The pressure switch connects to the 6V2 24VDC power supply on mine. That comes on a little later during the start sequence. Since there is no accumulator the pump will pulse on now and again very briefly, but it runs with a loud growl when you turn the switch on for tool change. Remember that the pump runs to release the tool by retracting the Belleville springs. When you release the pressure the springs pull the clamp claws back to retain the tool holder. The black hose on 5Y1 runs directly to the rotary joint on top of the Z axis. It also must get into the Y slide somehow, but I haven't looked at that.
I haven't bothered to bleed those hoses after I've had the spindle apart. My guess is they act rather like an accumulator so the pump doesn't chatter on and off. Hawe does supply the hydraulic unit with an accumulator if it's needed. Maho hasn't seen the need.
Good Luck,
David

 

Hi everyone.
I wanted to ask if a stop function for reading gcode blocks has been provided, via an ISO command.
Several CNCs have a stop for reading prediction.
Siemens uses a command called stopre
Rexroth uses a command called wait
etc..
This is important when performing mathematical calculations in the part program and associating values ​​to variables.
In these cases, the prediction must be stopped, the next gcode must be executed line by line, in order to perform the calculations correctly, and then resume the prediction.
If the prediction is not stopped, the calculations could be wrong, because they are performed before updating other previous calculations.
