Hi all
I'm close to loosing my temper. I'd be very thankful for any help.
I have a Ultimaker 2 with an Olsenblock. Because of a failure, I had to replace my old 2.1.1 Mainboard with a new one (2.1.4).
After switching it on, my Ultimaker 2 likes to go through this first calibration steps.
But every time he likes to level the building plate he crashes in the head. Actually it just happens once, every other time I was faster in switching it of before it crashed.
What Can i do?
I have to say that I had used the 8/16 jumper with the old Mainboard. When I set this jumper on the new Mainboard, the building plate doesn't crash any more. It also acheaves to level the building plate. But when it has finished this procedure and wants to home the building plate, h stops around 20mm before reaching it and launches the error "Z switch broken Go to: ultimaker.com/ER05"
I made sure that all the cables are connected at the right plug and properly. So I think it's not because of the connection. Furthermore I've measured the Z-switch with a multi-meter. It makes a short circuit when it's pressed. Otherwise it's an open switch. So I think it works also properly.
I have also installed the newest Thinker firmware (19.03.1) as well as the newest "normal" firmware. But with both happens the same.
I'd be really thankful, for any advice how I can get out of this mess.
For completeness, how the whole mess started, and why I had to change the Mainboard:
The walls of my print weren't very fin anymore. Some layers were staying out. I think I had over and under extrusion. According to the internet this lays because of the Z-axis. So i checked the 8/16-Jumper (which I sadly made my self with aluminium foil and tape). Because I thought, it may have a loose connection, I wanted to create a new jumper out of aluminium foil and tape again (what a bad idea, as I came to realise). While I was creating new jumper, the aluminium foil touched the PCB. Even it was not plunged to the power, it created a short circuit.
The Ultimaker 2 with the old (2.1.1) Mainboard could still start, but the Z-axis didn't work anymore. Every time I wanted to home the building plate the error "Z switch broken" came. That's why I ordered a new Mainboard.
Thank you for your help.
