That fixes one issue, but also creates another by pushing the PCB over another .9-ish mm. If those are 5mm long standoffs, I’d consider trying to source 4mm long to compensate if it’s tough to seat the module in the edge connector and still have the faceplate square with the rack. If the standoffs are aluminum you could also put a countersink bit in a drill press and take a little out of one end for the screw to recess in it, but that’s a pain. It may be fine how it is though.I managed it, I used an M4 washer...
I thought about that too, and yeah, as you said one can just fudge a little here and there. I may be a bit too OCD; it’s the draftsman in me haha.@thelivingroom I think this could actually be the solution to your Grayhill spacing comment. The additional washer under a 5mm standoff would provide that tiny bit of extra height to get them perfectly centered. Now, of course, that pushes the F2UEE switches out of place by a little, but a hacky-but-effective solution for this is to just assemble everything before soldering them, then use a finger to push them into alignment with the front panel (with caps on) while soldering the first pin or two. That technically means they'd probably be angled very slightly, but it will be so marginal as to be unnoticeable in practice. There is an inherent compromise between some of the mechanical aspects here, but I've been able to complete multiple units with very satisfactory results.
I totally get it! And I am always very impressed with your work.I thought about that too, and yeah, as you said one can just fudge a little here and there. I may be a bit too OCD; it’s the draftsman in me haha.
Oh, it sounds like the 3524 has different lead colors than the custom-wound 3523LP that was being ordered previously. That is good to know, I'll need to update the build docs with that info. Do you happen to have a data sheet? When I was writing the build guide, they hadn't published anything for the 3524 yet.Thanks for the M4 Info... Another thing:
Some of you might have received the UTM3524 already. This brings me to the question of wiring:
CMOB-3S diagram states Brn-Red Primary, Orange Yellow Secondary.
UTM 3524: Pri: Red-Blk, Sec: Yel-Org
So i assume its on the PCB:
Yellow - Yellow
Red - Red
Orange - ORange
Brown - Black
Correct ?
Appreciate that.With the fpd file, you can open ithe file in the free Front Panel Designer software, change the orientation and anything else (add your name), save it and send it to Frank at front panels.de
