I'm setting up a new HL-1060 with a 100W Reci on a 6442S controller and getting some weird results.

Does Min/Max Power% in the Laser part of the Vendor Settings set the absolute limits for the machine? So that once these are set the laser will not use more or less power than these are set for? And so that when you set power to, say, 80% for a cut it's really 80% of your maximum limit?

As far as I understand from the RDWL Manual (and other sources) these are all true, but I'm getting conflicting results. Is this right?


I'm testing cuts on 3mm hardboard/MDF -- as a sanity check can someone also with a 100W Reci tube let me know what speed/power they use on this material?

not really sure (i do not use these feature), but min/max power are used when you set the "default" setting on a layer. so, even if you have entered other values, if you thick the checkbox, the controller will use it's min/max values instead of the values of the layer.

this values are also used when you "pulse".

actually, you can go over those values. mine is set very low (around 18% if i remember) so i can pulse without burning too much (useful when calibrating the mirrors and not burn immediately the target paper), and my cuts are more powerful without any issue.

i have a 90W reci, and i cut usually 3mm MDF at 22mm/s, and my current is around 23-24 mA, where the tube recommendation for best life expectancy is to stay < 25mA.

Yes

Thanks.

I think the problem was with an improperly grounded laser tube, which resolved itself when wiring for an ammeter.
