Removing stuck PLA or ABS from print bed
by decoy341Hi everyone,
How is everyone removing left over pla or abs from the magnetic plate without damaging it. Is there a trick. Any help is greatly appreciated!

For some reason the links I have to download qidi slicer are all broken. Can someone provide me a live link to Qidi slicer? Thanks in advance
What are your start and end code modifications? Here is what I've come up with in order to optimize the X-Max start routines.
There were a few main reasons I did not like the original Qidi start code.
My start code aims the solve these issues.
Optional
Retraction acceleration set
In Cura there is no way to specify extrusion or z accel/jerk, so i added the commands to the start code. You can always remove that section at the bottom and it should print fine.
Note: If you are using the Qidi print version of Cura, change the X150 to X5. This will make the prime line go all the way to the left before the print advance line starts. I changed this because my bed/plate has a bump right where the detent in plate is, causing the line to be become so thin it was getting hard to remove.
From: G1 X150 A13 F2400 to
To this: G1 X5 A13 F2400

Please keep in mind that I offer no guarantee that this code won't damage your machine. There are multiple hardware revisions of the X-max and I cannot account for any of them but my own.
Use at your own risk.
Changelog:
March 25, 2020
This printer was unused for about a year due to firmware shortcomings. I just updated the firmware and now it has a picture menu. That's Okay, but I can't find the IP address of the machine.
How do I find the IP Address?
As the topic indicates, I'm thinking of changing the motherboard in this X-Max to something else.
I'm pretty much over the Chitu (should be called Shitu) board that's in it, its noisy, its locked down, Octoprint doesn't work well with it and I cant use Klipper.
I have spare Bigtreetech E3 RRF board, it can run Reprap, Marlin and Klipper, I think before I start to mod any more hardware in this printer, I would like to see how well it can actually perform with a nice control board in it.
Would anyone like me to post pics and a how too on this?
I will most likely replace the mainboard, install a RPI 4, camera, and a RPI touch screen for Klipper, along with a BL-Touch, and a Gyro sensor.
I see Qidi has an all metal high temp extruder for sale. Is this different than what came with my circa 2020 X-Max?
I'm curious what everyone's X-Max is running firmware wise. Qidi tech support told me I was on the latest, but my machine was built early 2019.
Version information can be accessed from the System->About menu.
Mine is currently
Version:v4.2.6.5 /W0.0.0
UI: Blue+ 1.0
EDIT: 20-01-07
Instructions from Qidi:
Please put these files on the USB drive home page, do not put them in the folder.
Power off the printer,then insert the USB drive,reopen the printer.
1.print the "update.qd"file. It will restart the screen and makes " didi
di" sound.
2.print the "UI_4_3-Single.bin" file
3.print the "wifiUpdate_full_V10.0.12.bin" file
4.print the "PLUS X-MAX Config.gcode” file
Some good news for Linux users, Qidi released a Linux AppImage version of QidiPrint 6.2.3. I tried it and it works even the network printing. I know many people prefer other slicers, but I've always gotten the best prints using the Qidi slicer. Now I don't have to boot Windows.
Just a quick notice I designed and published a fan duct for upgrading the small 30 mm extruder fan to a larger and much more quiet Noctua 40 mm fan. This mod will work for the Qidi X-Plus and X-Max.
