Help! After a long time sitting in the garage, I finally found the time, and tried my first 3d print on my A350T.
My setup for this print is an A350T, in it’s enclosure, with the quick swap kit. I loaded the G-Code file into a thumbdrive connected directly to the printer’s control board.
This was intended to be an air gap for a dishwasher, with a spout.
I used chatgpt to come up with the STL file, using my measurements, since I really don’t know any better.
It suggested we start by printing a fit gauge.
At first, I couldn’t get the the file to load on Luban, so I tried using Orca, but I kept running into an issue with it trying to print all the way to the right.
After more googling, I was able to get Luban to open the file by manually installing Rosetta via command line.
I thought that would fix the issue, but it actually ended up being worst, in that I heard a cranking sound - I’ve attached a video of that last attempt where you can hear it at the end.
I thought it was an STL issue, so I tried to print the vase that Snapmaker features on their tutorial, and had the same issue.
Has anyone encountered something like this, and knows how I may be able to solve it?
Ah, the forum wouldn’t let me add attachments.
Can you see the files in this folder?
I am using the Snapmaker 2.0 A350T, with quick swap kit and single extrusion toolhead, and the Snapmaker White PLA filament.
I am using Mac OS X and Luban to generate the GCode.
I uploaded 2 videos, the STL and the GCode file.
At this point, I was going to try and disassemble and reassemble the printer
Thanks @xchrisd
I bought it early when it launched, back in December 2021, but not via Kickstarter.
The customer service rep I was emailing with had recommended I swap out the X linear module with one of the Y linear modules.
I didn’t want to disassemble the quick swap module, so I swapped out one of the Z linear modules instead.
But now, am getting an error when I try to run the calibration process (attached).
I did a search on Google, and it told me to run the M119 command line after connecting to the printer via usb, which returned the following results:
M119 ok others < Reporting endstop status others < x_min: open others < x_max: open others < y_min: open others < y_max: open others < z_min: open others < z_max: open others < z_probe_proximity_switch: open others < z_probe_left_optocoupler: open others < z_probe_right_optocoupler: open others < filament_extruder0: TRIGGERED others < filament_extruder1: TRIGGERED ok
The printer also won’t respond to any manual jogging
Not sure which version you have but it seems your z axis are different to the X and Y. The stroke of the linear modules is different in the T models (for example A350T).
This means your Y and X are interchangeable, not the Z.
I can’t believe that your machine is as new as the faster linear modules came out but I can’t remember exactly..
Are your linear modules marked on the side of the stepper with length and stroke?
The older ones are not marked.
OH. So I should try and swap the linear module again.
Will give it a shot. I don’t recall anything in the setup manual about the Z linear modules being different from the others… Could be wrong
From what I see, it is really the old version, i.e. all modules are interchangeable. The GCode looks sane, and at the start of the print all looked good, then suddenly the X-module displaces. I remember that Snapmaker had problems that in some linear modules the silicon block for cooling the stepper driver was missing ( Z linear module not working correctly - #4 by brent113 ), and the stepper driver overheated at some point. You can see the “should be” state on this post’s image: Preorders delayed and new orders ship - #35 by lemmong - the light blue/purple-ish pads are what I mean. Perhaps check if you suffer from that…
Oh, and of course important question. Have you updated the firmware to something current?
@xchrisd you were correct. The X/Y linear modules are 20mm.
I reinstalled it again with the right linear modules on the Z axis, but now the Y axis is making a terrible grinding noise when it’s moving towards the front of the printer (where the touchscreen is):
Try to loosen or interchange again.
There are some bad pairings possible. If you disassemble the build plate you can see if the Y linear modules move different, what probably cause the grinding noise.
Am not sure what to think, but I just left the machine alone for the weekend.
I took another pass at it today, and just moved the Y axis around without any bed on it, and the grinding sound was gone.
I was able to calibrate the laser module without further hiccups, so I think I’ll keep this one dedicated to laser cutting, and use the U1 for 3d printing instead.
