The edge has a short give travel and there are many reasons why we designed it this way. The end result of the give is noticeable while tattooing as there is No tactile feedback on any part of the machine (no, the give knob is stationary and does not back off like an armature bar for example) However if you no give at all, you may have over torqued the give knob while trying to close it causing the spring to jam. Try this. Remove the give knob. Push the bar inwards with normal force and see if you get it to pop back up.
Another thing you can try is to run the machine high like at 12 volts for 5 seconds while opposing inward force towards the bar. Put the give knob all the way in without over doing it and back off 1 turn and a half. The travel of the give is about 1.8mm so don't expect anything more than that. It's just simply no needed with this setup.
We are dealing with cartridges that already have a spring. Let us know how that went. And for everyone reading this 1.5 turn from the no position is all you want to back off. The rest of the turns have no effect over give and just sets the screw in place.
