QTPLASMAC integrated cad/cam

Category: Plasmac

Here is two screen shots of the current state of the software, I am making it in python and will push it into the qtplasmac when its useable. im trying to keep it simple and easy/straight forward to learn/use. still is very buggy but am making progress. The goal is with the software is to bring the fabricator closer to the machine, its not to replace a real cad software just for drawing parts fast and easy. conversational cad.

Yes, typically this is caused by  a wiring error or worst case,
a damaged 7I77D output chip.

Check the wiring, or post pictures of the wiring here so we can have a look.

7I77D over heat

Category: Driver Boards

I am using a optocoupler (from amazon) between my 7i77D output and a solenoid valve for a spindle break in the sinking configuration, the output is over-temperature faulting for some reason.
using TB8 OUTPUT0. Field voltage is 24Vdc and driving the relay with the same 24 power supply. 
I set up the opto relay on the bench and it only draws 2.2ma on the input in low position.
I'm kind of at a loss, the manual says the outputs can take up to 350ma.

Please advise
John V.

I just had an idea: I don't need A/B/C, so I wired the feeds to these channels. It works way better anyway and I can use the jog wheel.

You can not use this in MDI mode due to when jogging, the WHB automatically changes to manual mode.
In auto mode with linuxcnc 2.9.8 without my patch, you probably will get a lot of error messages due to the whb wants to change from auto to manual. But this is gone with this fix:
github.com/LinuxCNC/linuxcnc/pull/3810/c...f939ee3cfb99275R1344

Thank you so much,  This video is helpful.

And I counld not find ESI upload function in SigmaWin+.
I agree that using SigmaWin would be better if I could use it to do that.

And I think .. sometimes updating new ESI to older software version device is a little bit risky..
I'm considering a little bit about it.

Anyways, thank you so much you guys.

  So I just came across this a few minutes ago. I am so sick of this new police state everyone is being forced into.
and this is just the beginning.

Hmm, mine shows always 0. In Mach3, Mach4 and LinuxCNC.

I'm pretty sure I just have a variant with a different buggy firmware than yours.

However, if you have time to spare, you can comment out the line in my last post, recompile linuxcnc and send me the result. Which version of LinuxCNC are you using?

Short update on that, Hannes. 
While in auto mode and running a program it doesn't show F: nor S:
It does react on Feed+/- and Speed+/- but only on displayed values in the HMI, not the pendant display.
In Man mode it shows F: and S: in the way one expect.

@Hakan:
Strange. Mine doesn't show anything. But it's an LHB04B-6 TX V3 (Wired version)
As much as I read, it should work the same, but might be not.

Starting with -Ha and commenting out github.com/LinuxCNC/linuxcnc/blob/master...whb04b-6/usb.cc#L209 it shows:

out 0x06fefdfe801800bc 060e0800161e0200 06008069006e0000
out size 24B hdr 0xfdfe dom 0xfe status 0x80 coord1 +0024.3772 coord2 +0008.7702 coord3 -0002.0000 feed 0105 spindle feed rate 00110

So it seams the values are sent. Might be my device has a different firmware. With Mach3, I tried already and I didn't see any value. I will try again with Mach4.

CiA 402 Folder Missing

Category: EtherCAT

According to github, that's a part of the feb 15 2025 commit:

-  hal_bit_t *request_cia402_homing;   // output requests homing (connect to cia402.n.home)
-  hal_bit_t *is_cia402_homing;        // input verifies custom homing (connect to cia402.n.stat_homing)
-  hal_bit_t *cia402_homing_finished;  // input from servo drive after homing (connect to cia402.stat_homed)
+ hal_bit_t *request_custom_homing;   // output requests homing (connect to cia402.n.home)
+ hal_bit_t *is_custom_homing;        // input verifies custom homing (connect to cia402.n.stat_homing)
+ hal_bit_t *custom_homing_finished;  // input from servo drive after homing (connect to cia402.n.stat_homed)

So if your example is older than this and that you compiled the comp from source, yes you have to use the current name. And if HAL tells you the pin doesn't exist, then it very likely doesn't exist.

The specs they list for that mini control box makes me think it is a servomotor amplifier. I see ratings of 48VDC 42A max and 48VDC 104A max on several models of the control box shown at your second link.

Interesting possibilities.
