Y Axis Misalignment Issue at a certain Height

by funshanas

Hi, everyone. I'm getting a problem in 3d printing a part. When it reaches a certain height, y axis of the printer slips and all the above part above that is misaligned a bit. I'm getting this 3 times, every time, gcode was generated separated, and placed command in pronterface, but the problem persists. If someone have solution to this, please help me in this regard. Pictures are attached.

BLTouch will not deploy

by Nhcraig01

Hello,
I just got a BLTouch and I cant seem to get it to do anything. I went into marlin 1.1.5 and enabled the BLTouch option. When I turn on the printer the sensor will light up red go in and out twice and then stop. When I try to deploy or stow the sensor manually or through pronterface nothing happens. I am using a ramps 1.4 and the wiring is correct. Any help would be much appreciated.

Proper belt tension

by dflash0

Has anyone come up with a bell tension gauge or guide lines on to know if you belts are tight enough? Currently printing near perfect lines on all axis. Was able to print http://www.thingiverse.com/thing:1019228 with all the detials. But eventually I assume the belt will stretch. I have seen the printed belt tensioners, and the one that uses the spring from wooden clothes hanger. What is the proper bounce? Is there a sound, like when tuning a string instrument? How much is too much?

Problem with Z Calibration - bad PRINDA?

by Jamie-Clay

After a long print my printer has decided something is wrong, perhaps with the PINDA?

  • It started with the error message - bed leveling failed sensor disconnected or cable broken

  • When doing a self test - I get the " Please check: Endstops Wiring Error Z" when it tries to raise the print head. But only when the print head is on the right side of the bed. If I move the print head to the left and redo the self test, it will pass

  • The PINDA light goes off when a metallic surface is near the tip

  • When trying to do a first layer calibration or mesh bed leveling I get a "bed leveling failed sensor disconnected or cable broken waiting for reset"

  • I've tried adjusting the PINDA position to no avail

  • I re-flashed the firmware version 3.1

So, I'm suspecting a failed or defective PINDA - is there any chance I can replace it with one from Amazon? I would like to get my printer back on line faster than waiting for the part from Prague.

Here is a video showing the Z calibration process. Note how it 'skips' over 3 right side points out of the 9 and the end just seems to stop with no indication of failure on the screen.

BTW- Has anyone replaced the PINDA with one of the ones found on Amazon, I can get those faster (and cheaper) than one from Prague.

Thanks

[SOLVED] Printer stops extruding mid-print then resumes

by ejalal

Hi all

I'm experiencing a very bad issue where my prusa clone stops extruding mid-print and then resumes like normal a couple of layer later.

I'm printing PLA at 210°C and 40mm/s

Can't be with the heater cartridge or thermistor because I have the thermal runaway protection enabled (Marlin 1.1.8)

I replaced the extruder motor but the issue is still present.

Please help :(

Edit
After following every single clue I could, I finally figured out that octoprint was skipping a whole layer and try to build up from there on an empty space which caused my prints to break a part.
I don't know the real cause of that, maybe a corrupted micro SD card or a bug but I won't be using it for long prints any more.
