But I guess adapting your files is not trivial. To me for a boards over 100x100mm or 120x120 mm, can't remember,was completely opposite, they saved me 20usd Last Edit: June 01, 2020, 06:40:38 am by minkok

Since it's affecting only one footprint, the issue is with this particular footprint.

Re: Really universal soldering controller Reply #2931 – June 02, 2020, 09:40:13 am Thanks Minkok! How would this neatly connect to the Unisolder board? Just double wires from the 6P6C connector to the appropriate jumper, except for Jumper 3, where only one needs to be connected at any one time due to firmware limitations?

Re: Really universal soldering controller Reply #2934 – June 02, 2020, 09:36:21 pm By the way, this holder is quite nice, but I really dislike sponges, and especially the tiny sponge supplied with this holder. Unfortunately, the compartment is too shallow to just use brass pad. I solved this by dremelling out the bottom of the compartment. This makes a nice cavity to put your brass cleaning pad in. Of course it's important to prevent solder particle to enter the area where the touch sensor is, so I glued in a piece of bakkelite to create a dust proof barrier. See pics.

The sensor behaves like it should normally, but now and again it suddenly responds to my hand again. The voltage between the tip and the holder is between 1,48V and 1,62V. This seems on the low side?
