Z axis issues on large build

[DUBE3D]

Hi there after a couple weeks learning the basics and perfecting my printer settings, I have tried a couple large overnight builds and about 5 or 6 centimetres up during the printing process the printer seems to glitch a centimetre or so off track. I am new at this and have no idea what this might be! Any advice or feed back would be great!

cheers

If a random “Glitch” then most likely a short in a cable but it could be a part of the print lifted and nozzle whacked it which then offsets the remainder of the print.

In the “short in cable” problem you usually end up with a ‘stepped’ object but is random.
Can’t find the posts relating to when this was a very common issue but check out the following posts.

MBot 3D Grid II printing error, prints slanted

[image] [image] I hope the images I upload are visible!... I done the calibration many times as well as the paper sliding between the nozzle & platform, after many attempts this is what I'm printing all my objects are side printing!... If anybody has any info on how to fix this please help! Thank you!

Prints slanted to X minus direction

This is my first time on a forum with the issue that I've been having. I bought a Mbot Cube Dual on eBay this past March, and have not been able to get it to work yet; it always prints objects leaning towards X minus by about 7 degrees. I have tried the following things: Removed X and Y carriage assembly, and reinstalled . Replaced a broken X-axis motor mount (right side Y-axis). Adjusted belt tension. Made sure that all of the timing belt pulley set screws were tight. Made sure every bolt in …

Plywood Cube - build plate moving while printing

Hello, I recently bought and assembled the Plywood version of the MBot Cube. The build plate is attached to the z-axis assembly using magnets. But there is a little bit of margin on the location of the plate and while printing the plate moves, giving an offset in the print. After a few layers, it moves back, giving a layered result. Does anybody else have this problem? Also, I needed to tighten the screws to hold the build plate, almost to the end, else, the plate would touch the printerhead…

Can’t find the original posts showing the solution images (I think Gigafaze posted some images) but if you can replace the X-Axis Endstop cable and the problem goes away that is the problem.

Make sure that you let your X-axis Endstop and Stepper Cable dangle directly down from the Stepper Motor and allow for a smooth curved movement forward and back. The original assembled printers (including Makerbot) had the cables fed above the X-axis carriage and rods towards the top of the case and towards the front and then down to the motherboard. That creates too much stress on the cable and VERY quickly you end up with a short.
