General

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've been using Cura on Linux for a long time with my X-max. (The Ulitmaker modern version of Cura) It works. But yesterday I booted Windows and printed some things using QidiPrint. I used the same basic settings for temperature, layer height, infill. The QidiPrint prints were noticeably better, especially the supports and first layer.

Not sure how I can replicate that in Cura. Copy every single setting over by hand I guess. Any ideas? thx

I'm having some uneven extrusion that I suspect might be filament dragging on the feeder setup. How do you guys have yours setup? It comes with a long tube and a short tube for where the filament goes through the body. One end has a metal bushing. I used the long tube with the metal end towards the outside of the printer.

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

• Added firmware package as received from Qidi support. I would recommend saving your current configuration with the M8512 command first instead of running their stock, just to make sure your settings don't change.

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 " dididi" 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

I have had my X-MAX for about a month now and I'm really enjoying it but I was considering paying for Simplify3D does it make much difference to print quality?
Any advice welcome, thanks

Hi,

i have this problem with mi QIDI Tech X-Max and I can't fix it. When I start a print, after a few minutes the motor overheats and the filament no longer escapes from the nozzle.

Thanks,
Andrea

Hello.
I have a problem with Qidi x-MAX.
The nozzle heats up and starts printing. After the third layer, the filament starts to jump every time. With head No. 1 and No. 2.
I need help. Rushes to.
Thank you.

Hi
I have a X-max and since some days connected via the usb TTL with an RPI4.
The first prints are working good.
Also on the RPI there is a filament sensor connected.

The Idea know is, that if the filament sensors throws an error, that the printer would react as the print was paused for a filament change.

For my understanding what I need:
Gcode for:

• save last printing position
• stop extruder
• cool down extruder
• move into a filamen change position

Then I would do the filament change via the Printer Touch

and after the change the gcode for the resume:

• resume print

Thanks in advance

For those that are not aware, Qidi have an official filament sensor for the X-Max, mine just arrived, I just finished installing it, but I made some mods while I was doing.

I hate the way they set this printer up with filament locations, I hate using the top mount as it tangles all the time, and the internal one, which is my preference, is shocking on the slap happy way they expect you to run the filament.

So if you look at my pics, you can see what I did, fitted the sensor inside, and run some PTFE tube to make the filament feed in and out nicely, drilled a hole in the back and run it out side then back in, it works much better now.

If you pick up the sensor (ebay US site) just email Qidi support and they will send you an install video and an updated firmware to support the sensor.
