Hi
Our 3dprinter has a problem. I can not fix this problem
Shift layers like this
We checked this items:
- change model
- change software
- change speed to 50 -> 35mm/s, and change travel speed to 40mm/s
- check y axis belts
- level 3d printer bed
Hi,you can check the voltage of your driver board, the tightness of your x-axis belt.
-Keep your mind and try to test it.
-Everything will be fun！-Support all Getech printer.
-You can ask me the questions and I will kindly reply.
-Respect others is the best way you can get help!
Have you tried upgrading firmware? There is no bigger waste of time than trying to fix a problem that has already been fixed.
I'd test the Z screw. Things move simultaneous, so a binding on the Z could be reflected in the X. Unlock the motors and turn the Z up and down. Then use the jog to run the screw all the way up and down, listen for any noises. Clean it. Look at the bearings on the far side and tighten the whole structure. check the bearings are tight.
Swap motors around and see if the problem shifts axis.
On the side of the lower portion of the box, look for a dent when the nozzle impacted the side of the box causing the missed steps. Or is there any bit of filament floating around in the belts that is causing the problem. With how good everything else looks, it shouldn't be a loose belt. You said you re-leveled the bed, also make sure it is tight and you have good adhesion between the bed and the print.
I can't imagine a gcode error that could cause it, other than the z-hop issue others have mentioned that newer firmware might help. I'm guessing the z-hop on landing can pound in like a tent stake and cause side motion issues, when combined with other variables.
Setup your camera to take a video and watch what happened. Set the frame rate low.
I don't want to sound like an octoprint salesman (octoprint is free), but it sure is nice to have a log file (and timelaps) to look back on and see what happened, rather than guess. If the problem is a motor error, there will be nothing logged.
The speed you are running seems slow, not that it should be a problem, just that you are not pushing the motor limits. I'm running at 100m/s and would not be surprised if I saw crazy stuff.
I had similar issues that were somewhat solved by tightening screws and having to slow everything way down. 30-40mm/s print speeds. Personally I think it was the travel speed up to 100mm that was doing it, but haven't checked that individual setting.
How does one go about telling which version of the firmware they need? I'm running the A30M, hardware version 1.7 and firmware 1.01.01. Any pointers on that and I'd be most thankful. I've got the toolkit, just not sure which firmware is needed.
Also, does anyone know how to calibrate E-steps? I know the process of extruding 100mm, measuring, and adjusting, but where do you enter those new values into the printer?
