Maybe I'm looking in the wrong place ?Is it L1 or L7 next to the power connector and switch?
Mmm..Hands up all those that have had NO trouble with bearings.
My home-brew slide mechanism is not very precise. Started building a second machine with linear bearings on 8mm rod. New scheme for Z but I have a problem that is completely eluding me, how to tell if the laser beam is perfect (or close to) vertical from the work. Any tilt results in a wide cut. I'm not sure that rotating the adjustment lens keeps it vertical. Any suggestions?
PWM isn't as sensitive compared to TTL so the dynamic mode isn't as effective but may still work.
What do you use for schematic drawing tools?I used DesignSpark for the first time on this; not done any for years and then it was pencil and paper!
ThanksYou are welcome. Something that is quite apparent is that the the manual soldering of trim pots, connectors and caps is appalling but the SMDs are OK; they don't seem to be able to put the base of the components down on the board before soldering so most flapped about a bit until I reworked it.
My laser also fires for about 2 seconds on burning power everytime I go into the control laser screen, How do I stop that?
Teflon tape is a very short term fix. Adjust it a couple times, and its useless.
Better alternative is to coat threads with clear silicone with your finger. It basically adds an oring to the entire thread base, and doesn't wear nearly as fast with adjustments.
Does this mean that the power ground and ttl ground are not connected on the laser diode power module?
