"MySweety Laser" Compatibility

[PalladinoDaniele]

Hi!
I'm trying to connect laserGRBL with MySweety Laser, mounting a CH340 chipset. The problem is that connection goes to time out!

I'm using v3.8 and driver is 2019 year.

Have someone solved this issue?

Ps: I've contacted producer/seller and no solution given

Thank you in advance

Dan

This is an help request, not a software issue: it is more correct that it is placed in the (new) "discussions" section.

Look like that this machine came with proprietary software, nothing in the amazon page indicates that it can be used with LaserGRBL.

In order to be used with LaserGRBL a marker must be equipped with a control board with GRBL firmware. I have no idea what that machine uses as a control board and firmware.

Do you have any information about it?

In the amazon page is written IT CAN SUPPORT GRBL, check image below is italian, the sentence you have to translate is: "GRBL può supportare"

Any ideas?

This is one funny name for laser engraver! 😃

I've recognized that software and machine. That software came with all JL1 based boards. Wainlux is one of main producers of machines with that board. There are a few more alternatives/no brand manufacturers, or just rebadjed, like this one.
Checking Wainlux site - sure enough, here it is.
That is K6. Click: ...support/software, find K4. Looks pretty identical.

Wainlux is nice enough to provide GRBL based firmware to users of their JL3 machines (using JL1 board), on request. Email their support and they will mail download link for GRBL firmware. That is for JL1 board that is for the same windows software as above.

I can only guess that you may try to request GRBL firmware for K4.

You may also open the case and see the board. If it is anything like JL1 - there is a few GRBL firmware options for JL1 boards: Official JL3 firmware, and couple more free alternatives.

Can you open the case and take detailed pictures of the board?

There is also a tiny bit mote tolerable phone app that support that rare protocol, with very generic name "Laser Engraving". Not a substitute to LaserGRBL but something fun to fiddle with, better than windows app.

Anyway, this is the product to check:
https://www.amazon.it/dp/B0842KWP12/ref=cm_sw_r_cp_apa_fabc_UZk3FbETY5218?_encoding=UTF8&psc=1

But I want to mark that the product is working properly with its own software, i bought it because of GRBL to have more settings....

[arkypita]

I google for mysweet laser and this one is the first result, but now I see that there is a lot of products with this brand (this is only a commercial name of re-branded anonymous product, not a real factory name).

Questo che mi hai linkato sembra più una macchina grbl, anche se la foto del loro software cinese mi fa pensare male.

Comunque, se fai una registrazione della sezione di connessione (menu ? -> activate extended log e quindi dopo aver dato il nome al file premi su connect) e poi me la carichi qui, posso dirti qualcosa di più.

[PalladinoDaniele]

Ok, this moment I'm writing from cellphone, but the extended log has a long list of "3F"....I'll upload the log asap

9600 doesn't look like a standard speed/baudrate for grbl engraver. Did you already try 115200?

[PalladinoDaniele]

i've changed to 115200 to COM port and also in the software, but nothing happens, I've tried now:

3F is a command sent by LaserGRBL to prompt the machine replying with a status report, but the machine does not send nothing and does not reply nothing (no rx lines).

A standard grbl session look like this:

Can you try enable Hard and Soft reset in LaserGRBL settings?

[PalladinoDaniele]

ok, so is not possible to understand the issue.....thanks a lot for your time!!!!!!!!!!!!!!

[arkypita]

I downloaded their .rar file which is linked on the amazon page. There is nothing in the machine manual talking about GRBL, they only give examples of their software. I fear that the "grbl" in the amazon sale is a hoax.

[arkypita]

MySweety Laser seem to be not a GRBL firmware compatible engraver, that is mandatory for using it with LaserGRBL.

I also de-compiled their "Laser Framework2.exe" program and from a quick glance it doesn't look like they are trying to talk to a GRBL machine, so I confirm my guess.

Theoretically you could try a flash of the grbl firmware which would replace their proprietary firmware BUT if the control board does not follow the classic grbl wiring and pins you would end up with the machine unusable and with no possibility of going back (I don't think they provide the firmware for a rollback).

---

La macchina "MySweety Laser" non sembra essere dotata di un firmware compatibile GRBL, requisito necessario per utilizzarla con LaserGRBL.

Ho anche de-compilato il loro programma "Laser Framework2.exe" e da una occhiata veloce non sembra proprio che cerchino di parlare con una macchina GRBL, quindi confermo la mia ipotesi.

Teoricamente potresti tentare un flash del firmware grbl che andrebbe a sostituire il loro firmware proprietario MA se la scheda di controllo non segue i cablaggi e i pin classici di grbl ti ritroveresti con la macchina inutilizzabile e senza possibilità di tornare indietro (non mi pare che loro forniscano il firmware)

[PalladinoDaniele]

Thanks a lot, mate!
