Can not change laser power level 5.5w
« on: January 18, 2017, 06:38:12 AM »
Hello, it has been almost a year since last posting about my 5.5w 30 x 40 DIY table kit from Banggood

I got it moving etc fine last year, the problem was no control of laser output, so I set it aside while I did the farming thing (no time)

This past weekend, we were at a winery and lasers got brought up (his wife had a neat necklace of wood) and we had same machine ect, I told him what my problem was and he said this:

I had same problem, and had to unsolder the ---- and move a dip switch, and then resolder ---- back on, download a new version of benbox and it works great now

setting 0 does not allow changes and 1 does allow changes

Does this sound right? if so any leads to changes? I have no idea what to search for

Thank you

I have the GearBest 5.5W A5 (small frame) and do not understand the solder etc. Which controller do you have?

Both Ralph (administrator) and Zax have instructions for converting Eleks controllers (L1, L7, etc) to PWM mode for use with BCL & T2Laser. Neither require soldering when using the onboard power MOSFET. It involves moving a jumper and reflashing the firmware. If you have a spare Nano (quite inexpensive) it might be safer to use it for testing as getting back the original Banggood firmware can be a pain.

If you want to go one step further, and your hardware supports it, you can convert to TTL mode which may provide finer control of the laser beam. This will involve wiring changes and might require soldering.
