DLC32 WIFI hangs when engraving : using Lightburn via VSP

[3Dangel]

Dear all reporting with my issue here: SW: Lightburn HW: K40 Co2 Laser Ctrl Board: MKS DLC32 V2.0

issue: engraving a job using Lightburn , via Virtual Serial port to connect via WIFI to DLC32.

The DLC32 after starting the job about 10 sec. will stop and will restart. Job cannot be completed. All basic function of movements via WIFI without issue. Only when sending a job to engrave will stop the operation. please any help? thanks!

I confirmed that too. DLC32 v2.1 using LightBurn via Virtual Serial port to connect via WIFI to DLC32 its starts working and freezes after a while.

I confirmed that too.

I'm also having this issue.

I've tried various gcodes, both engraving and cutting, generated by Lightburn, Laserweg, and Lasergrbl.

Operation freezes at some point, and not always at the same place.

Same issue With V2.1 board via USB cable, laser firmware is V2.10_H35_2022_0621_N_ZX_001, wifi connection is not working at all, wifi connection is ok (i can see it's getting ip from my modem) but can't connect via lightburn or via web browser and i trying with mkslaser mobile app with no luck.

with USB cable i cut and engrave couple of pieces but is not working now, after couple of seconds it stops, when i click the "show all" button on lightburn i can see Gcodes sended via USB but it stops.

i change the computer, usb cables even operating system, reflashing firmware

Edit: also i suspect becouse of cable management maybe cables create magnetic field which create problem and seperate all of them but no luck.

Also i notice one thing, when power off if i move laser axis, leds are on for a while. is there any protection for this? maybe it couse of this and burn some parts on board?

Couple of times i catch rebooting with abort() func, here is a backtrace

Edit: fixed problems; Wifi works: problem was my modem, i try with phone as hot spot and connection is successfull via web browser and telnet, also i can connect with lb too. if you can not connect via browser, use the TFT screen to see whats inside the sd card, then it works, i dont understant why. for information: you dont need to use VSP to connect, LB can connect via TCP/Ethernet, but you need to change $Telnet/Port to 23 in firmware config or you can change the LB's configuration file.

When steppers in connect, still stops some random time, it can close the wifi and open again, or closes the USB port and open again.

I'll try with different cables for stepper when it arrives. if it still hangs then i'll try with new board.
