Hello from Santa Maria, CA

[Scott Miller1]

Looks like I'm not the first Scott Miller in this forum. I'd have used my middle initial, but the system doesn't allow spaces.

I just got my laser last Wednesday - a DSP1060 from ChinaCNCzone, with an RDC6445G controller and reci W2 100 watt tube, 1000 x 600mm bed area.

Delivery took about a week. The machine showed up well-packed in a wooden crate, missing two of six wooden feet but otherwise undamaged and easily unloaded with my forklift. I got it out of the crate and discovered that it was missing the documentation and software. The vendor sent me some links, and while none of the documentation exactly matches my machine, it was close enough. They haven't answered any of my other inquiries since.

For some reason they had it wired so that the main 240V power input, straight off the circuit breaker in the back, ran through the door interlock switch before going through the e-stop switch and on to the filter and distribution block. This means that every time you opened the door, it'd completely shut down (including the air pump and any other accessories) and then restart and go through the axis homing process again. Tedious, annoying, and probably unsafe - the switch is a cheap pushbutton rated at 1.5 amps and it had to handle the entire load of the machine and accessories, and the inrush current of three power supplies.

The reason it's so baffling to me is that the controller has a perfectly good door interlock input. To enable it I had to find the manufacturer's password, which of course the vendor didn't supply. I rewired it and verified the interlock works properly. I may add a second, independent switch wired to the laser power supply since (as a professional programmer) I don't trust software alone.

I ditched the little air pump and added a filter/regulator/dryer to connect the air assist to my shop's compressed air. I also wired up the CW-3000 chiller's alarm output to the controller, which seems like something the vendor should have done. They at least provided the connector.

Yesterday I welded a rolling stand for it, with a shelf for the chiller, and once the paint was dry this morning I got the machine mated to the stand and the regulator mounted. I also removed the 6" exhaust fan - I've got the 6" flexible duct connected to my shop's 20" exhaust duct, which goes to a large 3-phase blower on the roof. Even with the machine powered off, the suction would spin the fan so fast I was afraid it was going to wear out, and the fan was just restricting airflow.

Overall, for $3500 delivered I'm not unhappy with the machine I got, but if I had been expecting vendor support (which honestly I had low expectations for) I might be upset.

I'm still hoping to find a controller manual that matches what I see on my screen, or a firmware update to get mine looking like the manual, but for now it's up and running.

Welcome Scott. You appear to hqave a good handel on making your machine work the way you want it too. Often the folks that make these tmachines have bizzare logic in how theu are wired.
