mixedgas replied to a thread Cheap iShow ILDA controllers - worth it? in Lasers, All Kinds.

Ditch the Ishow and get a Helios DAC and the related software from Gitti at Bitlasers. You will be much happier. Also it WILL work. ...

absolom7691 replied to a thread A little machining and other bits in Modifications

Still such a great movie! I am right there with you about laser sintering. DMLS has always intrigued me. I'm curious the price per print with metal powder and also with inert gas. 3D printing can be fun though. I know you'll enjoy it. As for designing, I'm not that great at it but I get...

LaserG started a thread Omicron ldm 450.1200 controller problem in Lasers, All Kinds.

I recently purchased the above stated laser and controller. My controller is shot and has no power output on the I/O connector to close the interlock and I’ve also tried applying 12vdc from an external source with no help. Has anyone else run into any of these controllers or know where I could...

LaserG replied to a thread Melles Griot 85-RCA-400 in Lasers, All Kinds.

I just bought the same laser and controller and I’m hoping it’s pretty simple. I have a universal controller and it works on my 26 and 85 BBB 20 just fine so maybe I can be lucky. It’s the CDRH controller but laser is coming with pcb controller that is the same exact thing because I’ve had...

VDX replied to a thread A little machining and other bits in Modifications

... no, it's not my friend - the design of "Vulcaman" is near to the Sintratec kit ... could even be a prototype for them. My "circular" design is pretty simplicistic, where the powder is "automatically" leveled by rotating the disc, without any moving parts ... the combination of "circular...

Hmmm - could be. I'm not sure of his real name, but the guy I was referring to goes by "Vulcaman" on instructables.com. Here's the link to his second iteration of DIY 3D Laser Sintering printer: https://www.instructables.com/JRLS-1000-DIY-SLS-3D-PRINTER/ Is that the same guy? How does...

mixedgas replied to a thread Have my cheap galvos hit their limit, or mine? in Laser Displays, Shows, and Scanning

If you have an oscilloscope, even the cheapest of amps usually has a position sensor Testpoint, usually TP1 is ground and TP2 is POS. TP3 will sometimes be after the integrator in the PID loop if it exists. TP 1 and X-TP2, Y-TP2 are usually brought out on a three position 2.54 mm header on...

Thanks buffo and mixedgas for your wisdom! I'm relieved that my laser-assembler's intuition of "stop if the setup makes a terrible noise" is correct. Amazingly I've not managed to actually break any of my galvo sets yet after quite a bit of 2000Hz+ circle-drawing/accidental...
