Laser will stop in the middle of a burn
« on: April 19, 2018, 03:31:34 PM »
So this is has been happening more frequently without any warning.  I have the EleksMark A3, the laser will be working fine, then the mother board goes dark and the laser stops altogether.  The software is still sending the information, so if the board comes back on it will be off by however many steps it was dark for.  I have taken everything apart and cleaned, I have looked at all the connections and they are all clear.  I can recreate the issue by just touching the control cover. 

Anyone have any advice on what to do?

bad power supply or bad power connection.
Laser: was an A3 2.0w TTL L6 Z axis now 2'x3'
          OpenBuilds ACRO 510 w/ 2.0W TTL laser Cohesion Mini Z axis Homing switches
          K40 Cohesion Mini 60W LightObject LPS
          80W Red-Black 500x700

cool is simply a subjective state of mind

Get a good quality replacement Nano and shielded USB cable, see if that resolves the problems.

I have a shielded cable, where can I find a link for a replacement Nano?

Any good quality Nano would work, either a genuine Arduino or a clone from ebay / banggood.
