Hello,
I have a problem with my Durst 1840 : When I press the controls to raise or lower the enlarger head, I hear a very slight noise at the control panel but the head does not move... (the control of the lens plate works perfectly).
Is the problem mechanical or electronic?
If the problem is electronic: will it be solved by changing the height adjustment card?
If the problem is mechanical: is it possible to modify the enlarger so that the head movement is manual (like on a durst 184)?
(message translated by deepl, sorry for the imperfections)
Thanks in advance

The motor is under the top cap. You can check for voltage up there, realizing the motor is on all the time, but locked not moving if the buttons are not pressed.
Thank you for your answer.
I will do what you suggest in July when I am back in my lab.
The absence of voltage at the motor level would mean the failure of the electronic board. Is it possible to replace it ? or to modify the enlarger so that the movement of the head is manual (like on a durst 184) ?

Dust L1840 Focus Unit
I recently bought a Durst L1840 with a Durst CLS300 Head, it has a motorised baseboard and a motor for the head. There is also a motorised focus unit on the side of the head with a remote switch on a cable.
Inside this focus unit there is a missing main gear.
Does anyone have info or pictures of what it should look like?
Ok thank you for the picture. Looks like a Durst L1800. Having one of the gears will allow you to figure the pitch and physical width. Knowing the shaft centers will give the diameter of the new gear. You should be able to have one CNC or 3d printed.
