I changed the 3D module because the temperature was dropping to 0. I have an enclosure on and when reinstalling the module my elbow slipped and damaged the Y rail. Now I can’t get the machine to calibrate. I go through the process but it doesn’t allow me to save.
try disconnecting and reconnecting the cables? could be an internal connector too
That has to be an unlucky coincidence, there’s no wires that go through right there. Take the end off and have a look inside, make sure things look normal.
Here’s snapmaker instructions regarding a different issue, but you can follow the video: https://support.snapmaker.com/hc/en-us/articles/360055281234-What-should-I-do-if-the-linear-module-can-only-move-in-one-direction-Snapmaker-2-0-
While the end is off see if you can straighten the steel strip somehow. If you have smooth jaw pliers or something that would be the best I think.
Thanks, I’ll give it a try
The bed will move but when I try to calibrate the bed it will not save.
The touchscreen calibration routine is well understood, it’s just a set of gcode it automatically issues. You could try and run a calibration by issuing the gcode line by line and see on which exact step it fails.
I posted the code for someone else to do an 11x11 grid here: Is automatic level compensation working properly?
You would change the 11 in the first command to 3 for a 3x3, or 5 for 5x5.
when it tries to auto level the bed it is actually pushing down into the bed before it hits the center point
Somebody had that same problem a couple of days ago, could not save the calibration.
Their issue was installation related, but specifically, because the prox sensor wasnt seeing the bed. The rails were not mounted to the base correctly and it was causing chaos.
Try to wave some metal under the nozzle and look at that shiny black part next to the nozzle. Does it light up when its close?
You changed modules but were previously using the machine with a different head like laser or cnc? or are you just starting out after assembly. if you changed modules, did you install the print bed and headed bed ?
you may need to adjust the sensor which there are posts about doing so.
I’ve had it working for about 2 months just using the 3D printer. Was getting great prints. Yesterday a print job failed. I was going to change filament so I set the temp at 215 but it would hold. I took the module off and changed the nozzle and tightened up the extruder.
I tested it out before I screwed it in and it worked. Screwed it in and slipped and dented the rail but the bed still moved but when trying to recalibrate the nozzle was pushing hard into the bed.
Then I did something really stupid and did a factory reset. Now the first step is to calibrate the bed. Obviously not thinking straight and frustrated because I damaged the rail.
DUDE if I had a dollar for every time I accidentally factory reset this or my other printer, or crashed it due to a careless gcode command, I’d have enough money to buy a proper CNC machine.
It’s the journey, not the destination. Or at least that’s what I keep telling myself.
One of these days I’ll stop plunging bits into my workpiece.
Too easy to hit the z when you mean to hit x or y. Or not waiting for it to change from 10mm travel to 1mm before you hit it.
