Finally... it works!

by CustomsUnlimited

About 3 months ago I purchased my BW from a friend who purchased it from a YT reviewer here in Australia. The reviewer didn't have a lot of nice things to say about the printer and commented about how it did really poor quality prints.

My friend spent some time messing around with it but he also has about 6 (no, I'm not joking!) other printers that work flawlessly, so he didn't want to spend the time with a problem machine, especially as one of his printers was a CR-10 and they are fairly comparable printers. So it gets unloaded to me as he knew I was struggling with the print volume of my A8 (I do LOVE my modified A8 though)

When it comes to time, I don't have a lot of it spare, what with running my own automotive business and my family. So, I've had the BW for about 4 months. Never ONCE got a decent print from it. My issue was always the bed levelling and Z offset. Combined with a lack of knowledge about this printer (remember it was already assembled?) it took me months of spending 5-10 minutes here and there to figure out how to calibrate this damn thing.

But I did it. Today, I stumbled across a .pdf which showed me how to do an "initial" BLTouch calibration and lo and behold, it laid down a PERFECT first layer on my test cube.

I still have to figure out what the deal is with the bed levelling. But I believe thats all to do with it where it believes the BLTouch is located compared to where it actually is. Because once it begins to measure the last row at the back of the bed, the BLT just misses the bed and consequently attempts to drive the carriage through the bed, through my desk and out the otherside of the earth.

I've managed to overcome it for the moment by waiting for it to home X and Y and then literally forcing the bed back about an inch.

Wires wearing down in drag chain

by ericthepoolboy

I'm having some problems with my black widow. I recently got a thermal run away error and traced the problem down to the wires that go to the heater block. It looks as though the red fabric heat sheathing wore down in certain spots from rubbing on the drag chain. And the wear continued through the silicone insulation. None of the other wires that are in the same drag chain look like they are experiencing any wear at all. Has anybody else had this problem? Is it just due to cheap wire or too much movement of the wire in the drag chain? I have six black widows and they are all showing some wear on the same wires. So I can only assume that they will also fail if I don't address this problem.

Enclosure

by NuClearArrow

I am planning to make a plexi box for the printer, but I am worrying about the wires and motors.I usually print abs with 240 °C nozzle and 120 °C bed temperature. Is there any part, which can be damaged by the heat inside the enclosure?
