Re: lulzbot mini smashing the sensor washers, again.

Great! Green or blue Scotchbrite usually does the job for me. It is non-conductive and can be used while the nozzle heater is on. update: I can get 1 out of 5 prints to work. Sometimes it smashes the first sensor, sometimes others. I clean it as good as I can and it seems to still be doing it. Mayb...

Re: lulzbot mini smashing the sensor washers, again.

I would suspect a dirty nozzle tip. You would be correct. My main problem was how do I get the gunk off without messing it up. The first printer I had I used a wire brush and messed it up bad. This time I shut the power off and disconnected it. Then I hit it up with some alcohol and fine grit sandp...

lulzbot mini smashing the sensor washers, again.

The same thing that happened to my first printer is starting with my second. My first printer had many successful prints using PLA until it eventually started smashing the sensor pads and grinding the motor. Eventually the printer got worse and worse getting more and more problems. Fast forward a ye...

The red wires have a slight bit of exposure where they meat the print head. I think I may have brushed that when I was cleaning.

Re: Z stuck, belts grinding, problems everywhere

Yes I will when I get home. To be perfectly transparent, I really went at that tool head with that brush. Right above the head there are some wires that I may have hit.

Did you remember to ground yourself before touching the new RAMBo?
Yeah. I'm really starting to believe its something to do with the print head.

Re: Workaround for malfunctioning z-min on miniRAMBo board?

Did you clean your extruder with a wire brush? That's how I blew mine. I'm having pretty much the same problem.

Re: Z stuck, belts grinding, problems everywhere

I have my fingers crossed for you that it is something else, but knowing that since the new board was installed the nozzle was cleaned with a wire brush which is something that we know can damage the RAMBo, and that 2 of your endstops are triggering on the same axis at the same time that is unfortu...

Re: Z stuck, belts grinding, problems everywhere

Thank you for those screenshots of your machine settings! Since you are working with Cura 3.2.27 to check your endstops you will want to start by making sure your printer is connected to Cura and that your toolhead and print bed are centered so none of the endstop switches will be held down. Then c...
