Hi savak001, I know this is a very old subject, but did you ever find any solutions?

Hi hichemhich, are you still trying to find a control board for your UMO? I am in the process of designing an upgraded version of the 1.5.7 board. A version 1.6.0 of sorts. But it will be awhile before I have tested out all the new ideas. In the process of adding new functions etc. I have had to first make a completely similar design, as the 1.5.7 board, so (if you are interested) I could produce a 1.5.7 similar board, so you have something easy to get you started. I do these PCB designs (and 3D printing) as a hobby, so the price of a board would only be the cost of the materials. I am a 'die hard' UMO (and UMO+) fan, and was previously using an UMO at my local makerspace, but I just recently got myself two (used) UMO printers, that I am modding and upgrading. So whether you would like a 1.5.7 similar board or not, then I have just decided to design a SMD version of the 1.5.7 board. I have previously hand made some enhanced RAMPS 1.4 boards, and they had a material cost of about US$12 + shipping. The 1.5.7 board uses a special switch, so that will add about $2 to the cost. Because I live in Europe, then International shipping is a bit expensive. The cheapest (but still safe) method of shipping an electronics board, is to send it as a registered letter, which is about US$ 20 ( DKR 132, Euro 18) So, are you still looking for a 1.5.7 control board?

Some more information about how you updated the firmware might be useful. And which type and version of firmware you chose, might also be very helpful to know. And UM+, is that short for Ultimaker Original Plus?

I would like a clickable option in Cura, where the fan is turned ON when ever the top layer (of what is otherwise considered an infill area) is being printed. Right now I need to edit the g-code file in order to tun on the fan. But it would be so much more nice, if a general (clickable) option was available. If the infill level is low, then the top layer can be considered as a lot of short bridges. And bridges come out better, if the correct level of cooling is/can be applied when printing the bridge. Any other suggestions, of how to automatically add some cooling to at least the first layer of the top of an infill area?
