Yes, fortunately, a good cleaning was enough. For cleaning the Z-axis I used Isopropyl Alcohol and a toothbrush and wooden tooth pickers. I don't like the grease for the Z axis. I have used light synthetic oil for all axis. https://youtu.be/LvsammgGDhg I have to admit, I bought this printer in 2013 ...

Dear Ed,

Thank you for your support,

I expected it to be the stepper motor, but I'll start with a thorough cleaning ... I have work to do

Just can't explain what that weird sound is?

Kind regards,

Hi, My MakergearM2 printer has not been used for a few months and now shows strange behavior. The heated bed doesn't go up to its homing position. If the heated bed is is at his highest position, it goes down to the middle position and start printing. :? Can anyone explain what is wrong and how this...

Hi, Problem found :D . It was the Molex connector, or rather one of the wires had too little copper. The connector was molten inside. I can not find easily the Molex 3953x so I switched the one which is used for the fan. The fan is connected with 2 small single connectors. I've crimped 2 wire-end fe...

I just checked the resistance of the HBP (closed circuit) and the thermister (+/-97 K) at both connectors and that seems OK. After a M140 S30 command I see the red leds burning at the Rambo board and I measure 0V between the HBP mosfet output connector and a GND contact point TP24 near the HBP power...

Hi Ed,

Thank you for your explanation.

The MOSFET acts as switch ...

, that means I can connect both wires to check if the HBP is still working?

Kind regards,

Hi, It looks like my HBP isn't working anymore. My prints won't start cause the HBP doesn't warm up so it cannot reach the right temp. I checked the seperate12V power input on the Rambo and that is OK. At the screw connector (on the Rambo board, at the right side of the Fan 1 connector) I don't see ...

Hi, After printing for 3 years now without any problems using Octoprint, I updated Octoprint to version 1.2.10. Everything looks fine except my printer doesn't start the printjob. Now, it seems I'm suffering from a Marlin bug and I was pointed to https://github.com/foosel/OctoPrint/wiki/FAQ#i-cannot...

Oh no, it's a little misleading, the object is 100 x 80 mm

Kind regards,

Hi, Yes I'm up and runnning again ;-) http://i49.photobucket.com/albums/f261/whenim641/Broken_zpskf0kssdy.jpg Finally I found the problem, http://i49.photobucket.com/albums/f261/whenim641/Bypass_zpsgi5dufrh.jpg ... a bad connection on both wires at the connector, I could pull them out and unfortunat...
