I will post you a new plexi glass. See if that works.
It has been CNCmilled a bit differently.

Ofcorse it can be done by boosting the signal by adding a boosting stage to PreenFM eurorack format.
But it can also be done with an extra module like Erica Synth Pico Input.

I will try to work out a solution to add an extra gainstage to it. But in current design its not implemented.

Hello,

Replace the OLED-resistor with a wire or Resistor leg. You have a Blue OLED screen. So you should have a 0 ohm there not 22ohm. Thats why the Screen shuts off.

Yes thats the correct way for the Plexy glass.
I cant see the reason why it doesnt fit. I just built 2 units from the same DIY kit patch and they all fit.
Try to push and resolder the Pinheaders for the Screen and Mainboard tighter together against the boards.

Can you tell me the length of the Spacers?

Press that Plexy screenprotector inside the Frontpanel screen hole. It goes all the way until its sitting flat.

Hello.

Please send a picture taken from the same angle but without the Bottom case part.
You can solder in the DC jack. There is no issue with it. If it doesnt fit. you need to solder it in a correct way so it fits.
The jack can be moved inside the PCB holes to make it align.

You got it from me!

You could poke it a bit. First open the Case by removing 2 screws from the front side (Not top)
And then remove 2 nuts from the Output jacks. And then it opens up.
Try to poke the Screen and see if its contact related issue.

Or Send it back to me, I will fix it for free.
Its not known issue.
I have had one PreenFM running for 2.5years 24/7 non stop.
OLED screen has burned in. So Even after I remove the power I still see the picture on the Screen. But otherthan that it works.

If you look at the back of the unit. You will see 3 jumpers.

2 of them will change the GATE and V/oct levels.
You should change the jumper positions according to your system.

GATE jumper alters the levels 0to +10V or -5V to +5V.
Choose the position according to your GATE signal.
Same with the CV2 which is used as Volt per octave control.
You can also choose 0 to 10V or -5 to +5 region.

Hello,

Please also see what are the Jumper positions on the back of the unit.
Also make sure you are feeding the correct Gate signals to it.

I will try to make a video how to get things going in the beginning.
