Need help for CO2 50W laser (Artsign JSM3060U) #370

Open floods57 opened 1 year ago

floods57 commented 1 year ago

Hello,

I have a CO2 50W laser (Artsign JSM3060U) that use the old NewlyDraw software, it is now a very old soft with bugs.... so i looking to upgrade it with a DLC32 board, but i can't find anything about how to wire it, i see some K40 laser installation, it is similar, but not the same.

Here some pictures of my actual board/install : IMG_20230417_171024 IMG_20230417_171042 IMG_20230417_171101 IMG_20230417_171127 IMG_20230417_171143 IMG_20230417_170900 IMG_20230417_171522

My 1st question is, did i need anything else ? new stepper, or are this one compatible ? i think i need end stop (there are not actually).

I have a Microstep Driver (M542-05) if i understand right, this one is just used for the table height control, that is fully manual with a up and a down button, so the little green board just over the microstep driver and the driver itself is just for this use ?

The board of the 1st picture is the one to replace with the DLC32, but i have to find out how to wire the laser power supply to it and keep all the function, that look to be the most complicated part if i am right.

Thanks for help

These are just theoretical considerations, you do everything at your own risk.

If you do not want to control the laser power by software no additional circuits will be needed. Connect "TTL Output" from DLC32 to TH input on laser power supply and GND of DLC32 to G on laser power supply, TL input leave unconnected. In software use always 100% power.

If you want to control the laser power via software, you have two options.

  1. Switch on laser manually by button. The laser will by work continuously on Pmin and by software you can regulate the power between Pmin and Pmax. TL connected to button, TH unconnected, IN connected to "TTL Output" from DLC32.
  2. Build an additional simply circuit (555 base like Z control board) that will be generate long pulse (500ms e.g.) on each pulse from "TTL Output" and connect if to TH or TL, "Laser Switch" to WP and "TTL Output" to IN.

Remember, this device is mains powered and produces very high voltages and is deadly dangerous.

Thanks for help. Ok, so i prefer the second option to keep the power controlled by the soft, the option with the 555 look good, is there any schematic to build it ? A other solution i was looking, is remove the CO2 lader and buy a new 80W (10W optical power) laser head, but i never use one of this, is that better or similar to the CO2 laser ? maybe it is more easy to use with the new board.

Thanks

A cheap Chinese laser a fake laser, an expensive Chinese laser a fake laser usually too.

Ok, so better to stay with my CO2 laser. Now i have to figure out the right diagram to connect all together.

I have this 60watts power supply can you help me wire this up?
