Re: Multiple lasers on one water reservoir and chiller?

You may get a better idea of what I was talking about with the drawing.

Re: Multiple lasers on one water reservoir and chiller?

The idea was to run a pump for each machine and a separate pump for the chiller just to circulate the water from the tank.

Multiple lasers on one water reservoir and chiller?

I have 4 (60W) laser machines I was thinking about running out of one large water reservoir and using a single large chiller (Lightobject 1600W Water Chiller).

Is there a reason that I should not do this?

Thank you,
Tim

Re: Melting switches

How would I wire up the DC side of the SSR?

We are using 125V 10A fuses BTW.

Any pro tips on checking that LPSU? We can run it for maybe a few minutes now and then it blows the fuse but while its running it seems fine.

Re: Melting switches

Blowing fuse is another issue!! Stupid things is the power voltage in China the power is 220V so if they put 5A fuse on your machine, then you need to put 10A if it is running AC110V now. You know how stupid those manufactures there?! That's why I always tell my customers do NOT touch those machine...

Re: Melting switches

A customer from Bay area who brought us that particular machine for service a couple times. Finally we couldn't do much because the laser headf and pulley got damage. It is very hard to get spare parts for that machine and the customer ended by a new machine from us. Anyway, you can't use the E-Swi...

Re: Melting switches

The SSR, heatsink and the power supply are good. I don't know much about your machine but I won't use that switch to replace the main power switch. Remember that the label of '5A' is the peak current and for a 60W laser machine, the overall power consumption could be as high as 700W or 7A. Marco I ...

Re: Melting switches

It seems that you have a very low quality or low current switches installed on your machines. Any 25A SSR is good enough for your case.Get DC control, AC output type SSR and a small heat sink It take DC 3V~36V to operate. So, that you need one of DC power supply to be "ON" all times in or...

Re: Melting switches

@TimAustinTX: It shouldn't happen to 60W or smaller machine. I guess you have 80W or higher power laser, right? Many laser exported from China has bad practice: use a single toggle switch to control the main power. Most of those switch can handle up to 8A current and for 80W, the max current may ru...

Melting switches

Hi,

I have a couple machines that have shown signs of heat damage to the main power switch. I swapped them but then they started to blow fuses.

Any ideas on what would cause this and a fix?

Re: Belt problem?

After a lot of work I believe we have narrowed it down to the axis stepper motor wiring. I believe the wiring on the X-Axis motor is shorting out or something of that nature.

I have checked the temp and it seems to be fine.

Re: Belt problem?

I don't know if your motor run out or not. That's why I asked for your setting information see if any hint that lead to the problem. Please reply with the info I requested. Or, I have no idea what you're running with Marco I am running the "DSP upgrade kit for D/K40 small machine" (AWC608...

Re: Belt problem?

Ok so I discovered that the X axis will stop working after a few runs while the Y still works. If we power the machine off and back on it works again.

Any tips?
