Hello Guys!
My first thread and question for the group! I thought I would share and document my upgrade with the rest of the community, so we can have a reference and have the ability to ask a couple questions along the way. I know there is a good discussion about this on Lens Digital Blog and I bought Len's tube mounts for this upgrade last year.
I currently have the SH-G350 50W laser cutter engraver from Ebay and until this week has been performing satisfactory. Early this week, my 50W tube (I know not a true 50W tube!) finally kicked the bucket. I had planned on upgrading to the 60W tube once the the old tube failed, so I ordered the new PS and tube from Light Object (LO) and should have everything by the end of the week, so I can get back up and running.
Everything seems pretty straight forward, but my old power supply, I believe it is a Cloudray MYJG-40W, has a different pin setup. I will confirm PS model number at lunch. It has a four, six, four plug configuration. The new LO PS has a three and six pin connector. This would be easy if my old power supply matched the new one, but I am not that fortunate!
I have a Ruida RDC6442G Controller and downloaded the schematic for the Rudia website and uploaded that schematic as well.
I spent yesterday tracing the wires from the old power supply, so I have a good understanding where they go and trying to understand where the wires will go into the new PS. I think I have a good handle on the three pin wiring, but have a question on the new six pin wiring.
I believe my current setup uses the controller for water protect vs the PS, similar to the RDC6442G wiring schematic attached. Want to confirm with the group that I would connect the new PS like the controller schematic? According to the schematic I will use L-on 1 CH5 (Pin 2) to Trigger Low (TL) turning the laser on and off and LPWM1 CH5 (Pin 3) to the Input (IN) on the PS to control the power output of the laser.
I guess my main question comes with the water protect circuit, but looking for advice for all connections. I have attached the first three pictures and would like to get feedback from the group, maybe a little confirmation that I am understanding this correct. I just don't want to mess anything up and I hope my pictures help.
I did search before posting, but did not see anything in depth about this, so I am a newbie and don't beat me up too bad! Thanks and I look forward to sharing the upgrade. Thanks and talk soon.
