G+_Jennings Mercer Posted July 24, 2016 Share Posted July 24, 2016 Is this possible Looking at this paperwork "SOL 1064nm User's Manual 6 to 40 W (EN) 2014-12.pdf" Can I wire a 5 volt power supply to the digital pins 1,3,14,15,22 and variable resister POTs on the analog pins 12 and 20? The digital output pins are for system checks and analog output for monitoring amps Digital Pins 5,6,7,8,9,10. And Analog out 4 Without a computer at all or is a computer required for digital outputs? I may need a PC for the rs232 or is that just for remote monitoring and will do not need that if we are running on sit. https://drive.google.com/file/d/0B-Tfm3HY0PZeempJUHBlWVpyQzA/view?usp=sharing https://plus.google.com/112534107153471500374/posts/jWA32pTAE16 Is this possible Looking at this paperwork "SOL 1064nm User's Manual 6 to 40… Is this possible Looking at this paperwork "SOL 1064nm User's Manual 6 to 40… plus.google.com http://plus.google.com Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 24, 2016 Share Posted July 24, 2016 Just a quick look over: No reason to have 14 (aiming laser) on while cutting. Seems pin 20 doesn't want a CW signal, but pulsed @ a voltage. And works with #13 Pulsing lasers is typically a good thing (but *slow*), but shouldn't be done on SS or alum. These are are very reflective for a CO2 laser. And forget copper, the mirrors are copper (not silver) Get the circular polarizer!!! Without it parts can keystone themselves in (ie: not a straight vertical cut, and angle varies on cutting direction) (I have 20 years as a CNC CO2 Laser field service engineer.)

G+_Eddie Foy Posted July 24, 2016 Share Posted July 24, 2016 Oh, you will still need beam delivery method, optics (fiber optic is NOT a solution) and of course a focusing lens. Link to comment Share on other sites More sharing options...
G+_Jennings Mercer Posted July 24, 2016 Author Share Posted July 24, 2016 Eddie Foy Thanks for responding would that mean that I will not have to have a computer (arduino, raspberry pi) to control this. I can use a switch on 14. How would I control 20 ,13 with a pules? Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 24, 2016 Share Posted July 24, 2016 You really need a computer. Lasers need to modulate the power and speed as they go around corners, piercing, and such. its not just on and go. The ones I work on have at least 30 (up to 70) parameters to cut. (though the main ones are speed, power, focal and assist gas) You really don't want to pulse cut (maybe pulse pierce) Its just too dang slow (on the order of 10% of CW speed) What are you trying to actually do with the laser?

G+_Jennings Mercer Posted July 24, 2016 Author Share Posted July 24, 2016 Eddie Foy using it in medical application but I have no controler looking towards using a raspberry pi.but the laser needs 5 volts. And the pi is only 3.3 volts. The arduino is 5 volts not sure if it will do the job. The laser is more than sufficient I will only be operating it at 70% power.

G+_Eddie Foy Posted July 24, 2016 Share Posted July 24, 2016 There are level shifting Pi shields (3.3-5 and 5-3.3). Don't use the bidirectional ones, they have a bit of latency. Adafruit has them and I'm sure SparkFun does too. Link to comment Share on other sites More sharing options...
G+_Jennings Mercer Posted July 24, 2016 Author Share Posted July 24, 2016 And of course that would be the shifter I used. Link to comment Share on other sites More sharing options...
G+_Jennings Mercer Posted July 24, 2016 Author Share Posted July 24, 2016 And couldn't get 5 volts Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 24, 2016 Share Posted July 24, 2016 You will need to supply the 5V. They don't boost the voltage. Think of it as a relay. Link to comment Share on other sites More sharing options...
G+_Jennings Mercer Posted July 25, 2016 Author Share Posted July 25, 2016 So looking at this an arduino is 5v. But, Is capable of making the pules for pins 13 & 20? And is the rs232 required or can I leave it out for less coding Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 25, 2016 Share Posted July 25, 2016 In all honesty, if you are going to use pulsing, use a micro controller with a dedicated hardware PWM. They are free running and the program loop has no effect once configured and started. (I'm sure the arduino has at least one) But in typical arduino fashion any pin can do basically any feature via software. You really want to use the on board/hardware feature there (especially for a medical device) I haven't looked at the datasheet for the atmel(?) chip, but know the PICs definitely have them (that's what I cut my teeth on) I might have been (probably) wrong on the pin 20 needing a pulse too. Look a little further down and you will see the timing chart, of how things need to go. Link to comment Share on other sites More sharing options...
