cool, thanks heaps man, will try that out

so between the + and ground of the 5v TTL in, before the connect to the board? (in this shot is the white and blue wires on the right of the driver?) i'll give that a shot, but yeah, it's annoying that the TTL circuit doesn't do much to stifle the laser, behaves more or less the same with...

i've been working off and on again on my laser cutting cnc for a while now. initally i was going to use a 445nm m140 diode, but i'm now playing around with a s06j 12x, with a g2 lens. i'm getting some good cuts, but i haven't been able to get the ttl working, it's always on (even with the TTL...

if i switch plugs i get drastically reduced brightness out of the diode, and the values max out at 157. but yeah, if i put the dial to 10A, i get .43, which is 430mA. not sure what gives. i just looked at the current coming out of the computer PSU and it's about the same, 400Ma, this driver...

yeah it's weird, i'm a bit of a noob at measuring current with the multimeter, but i'm pulling values like this at the upper end of the potentimeter, with the laser still going.

I'm fairly certain it was at that, but that said I might have misread the multimeter. the diode ran fine thereafter (at a safer current). I've ordered a 405 12x in casing and will use the g2 that's on order, and this driver with it. you can have the control module since...

so i might have been a bit quick on the draw to say the driver is only putting out 1A, i was just a n00b using the multimeter wrong. the potentimeter on the o-like driver can push the current as high as 4.7A, which is odd, because olike rate it at 1.2A constant max. running the laser at 1.2A is...

given the massive heat dissipation needs from the 12v input, why didn't you use the 5v from the PSU, wouldn't this require less energy to be wasted as heat?

i'm using one of these to control the spindle/laser. a db25 serial connector turns the spindle (or laser ttl) on and off. MyDIYCNC Spindle Control Module | MyDIYCNC - Home of the DIY Desktop CNC Machine people on that forum are using them for (US?) mains current, which iirc dremel uses (my poxy...

yep, will definitely post pics of any output i get out of it cool, i'll see if i can hunt out any drivers that fit the bill, other than o-like and the dtr shop are there any reputable sources to check out? most of what i'm finding seems to be geared towards battery power

A while back i posted about the CNC mill i had, and was going to adapt to a laser, so here's where i'm at so far. the CNC cutting/burning area 30cm X 19cm. adapted from a kit from here, modified to increase the work area. control box. built this to include a mini ITX psu powering the stepper...

cool thanks heaps for all your help, i bought those, and a variable focus host that i'll drill through a cpu heatsinc and fan then goop into place with heatsync glue. will post results when i get it together

'You must spread some Reputation around before giving it to Things again.' cool, thanks for all the help, i'll confess, i did buy this before i did much (any) research, but a bit of reading changed my mind. One high burning power (500mW) 808nm TO-5 9mm laser diode + Gift* after reading about...

oh cool, so the ttl just triggers an internal relay of sorts on the driver? would i be better off running a different diode with that driver, because it seems like the current it can put out might not be up to the diodes requirment. or can you safely underdrive it and it'll still be up to light...

sorry if this has been covered before, i've done some research but i can't see any threads that match what i'm doing. i'm looking to put together a laser cutting head for my CNC which i already have running. It's just to cut paper/card (all colours) and maybe leather or cloth. I originally had...
