Is it ok to use paper clip? Or how should I do that.try connecting pin 1 to 11 to enable the interlock!

Ideally you would use a cable like this: https://guideimg.alibaba.com/images/sho ... 13280.jpegZeta wrote:I already replace the power supply to 5v 10A 50w and power it direct to the controller let it warm up 1 hour pass it's hot (+-40C I think) (heatsinked) but still nothing. Then I take analog readings

When starting, don't worry about that. Just heat your glass plate and emulsion to 40c to start and veil coat. You don't really even need to spin it to get a decent result.Zeta wrote:I think I will buy a new one from sam's laser.
And how thick should my emulsion be?
Zeta, please try this if you can.Zeta wrote:Has anyone ever tried silkscreen technique for coatings?
I totally agree.pluto wrote:coating plates is currently one of the most tedious and unreliable parts of holography for me.
A thread about novel coating methods would be great
You are measuring the output of your power supply off load - laser not connected.Zeta wrote:I think I will buy a new one from sam's laser.

You should have found an appropriate power supply. The voltage only drops from 7V to 5V under load. There will be times, even if brief, that this load disappears. Then you get 7V pumping into this precision laser driver -- not good. I don't even trust the mains voltage going into my laser power supplies. I highly recommend using a voltage regulator and surge protector to power your laser systems. Small price to pay for peace of mind!Zeta wrote: About laser I increase output from power supply to 7v and now pin 4 is 5v but still nothing.
