I installed a Polar Cooler on my MAX4, but the original T-shaped cable ties kept getting caught on the top glass panel. So I lined up several PTFE gaskets on the airflow pipe and attached them, and now they don't get caught anymore.
I wanted to document as much of the machine as possible in one place as well as house some FAQs, mods, etc.
I just leveled the bed, didn’t skip the pre-print bed leveling, and I had the filament drying for a couple hours beforehand. Why is my first layer still coming out so poorly?
I read that most of the juice needed to power the printer is for the aluminum bed. Since it has a heated chamber - wouldn't the bed be largely unnecessary after a certain layer height? I hear you can turn off the bed in the slicer. Is this a really bad idea?
Considering a Max 4, possibly a Max 3/Pro (I almost got the bambu X2D but I don't like the shady shit they do). I would like to start a business designing and building difficult to find parts. Parts that require advanced filaments, and can survive in all kinds of conditions, sunlight, weather, engine compartment. I'm not considering body mods for cars unless I can piece them together, I don't have the capital for such a machine, and it sounds like an area I would need to specialize in.
As far as my exp, I purchased an ender 3 in 2020. Was very enthusiastic, modded it very quickly, and didn't normalize print quality between mods. I got functional prints for a bit, but print quality began to degrade (changed the bed springs, build plate, hot end, nozzle, and mobo to put marlin on it). I changed too many variables at once, and the nozzle kept clogging, and I couldn't get it unclogged. After a while I got really depressed and just gave up on it.
TLDR; Is my experience level suited for a QIDI 3/4? Or should I get the X2D anyway to know I like 3D printing for sure first?
Hi guys, my Qidi box has filament stuck in it (PLA). In the process of trying to remove it (push/pull) from both directions, it broke. I cannot get to the part inside the ptfe tube as I’m struggling to figure out how to take this apart further (can’t get to the next clip for the tube.
Turning on the box causes a loud and really fast grinding noise as the motor is attempting to extrude but can’t. I’m worried the gear will wear out of I keep trying to turn the box on.
At this point I’m stuck on how to further proceed.
My first level looks wavy. Not sure why. Trying to tune in the profile.
SOLVED: Found my old hotend that i had replaced before and it heated up no issue. Need to buy a new heater or complete hotend.
Already submitted a ticket to Qidi but its friday, starting a weekend, and 4AM for them so I'm posting this here in the mean time to get answers. I'll copy and paste what I wrote to them.
I was starting up a print on my Qidi Q1 Pro, it went through the startup process just fine. I heated up the nozzle and put filament in and purged the old filament. During the startup process it heated up in the back to wipe the nozzle. It then did the bed leveling and went to the front left corner to heat up before starting a print and tried heating up but never did, it was stuck at its temp and couldn't heat up. I already replaced the complete hotend in a previous ticket so this is the 2nd hotend I'm on and has around 200 hours on it.
Some troubleshooting I've already done so far:
I can try and heat up the hotend and check the connector to the heater (black connector on the top of the hotend board) with a multimeter for voltage to see if it's going through or not but I do not want to do that unless I can confirm its ok to do.
Hi peeps. My Xmax 3 is only like 4 months old, but have around 400hrs on it. I'm getting terrible layer lines and banding now. I have calibrated all the filaments, cleaned lead screws, stripped extruder, manually leveled the bed and ran calibration. But still bad quality.
I mainly use it for large abs printing.
Hi all, I've been spending the last couple of months looking into various printers as I plan on getting my first in the coming months. I really like the Q2 for its versatility when it comes to material choice, however, some reviews I've come across (from 2025) were saying the QIDI Box wasn't working correctly - putting too much resistance on the filament. The reviews mentioned QIDI were supposed to be updating the Box to rectify this.
Can anyone with a Q2 + QIDI Box advise if this is still an issue?
But there are some issues I want to address that this fauxhammer review shows.
I think most could be addressed through firmware, and the rest have possibly been addressed in the months leading up to release.
The PTFE tube smashes into the glass lid when open, and wears away the material. I think this could be fixed by attaching a custom designed TPU piece to the lip when the cover is open.
AI approves. What do humans think?
The lead screw has no cover, and can get junk inside, messing up prints. I believe this can also be fixed with a TPU cover that snaps together over that hole. AI thinks a different fix is better.
A full tight TPU sleeve may:
A better design is probably:
Think:
“umbrella”
not
“airtight sock”
After searching up the Qidi box, I found that someone's already fixed the noise with grease. The thought of taking apart the box intimidates me. But AI likes it too. And you?
I'm well aware that AI makes mistakes, I've worked with it before.
TLDR; are these issues still present on the machines being released to the public now? Also, what's the process to change the nozzle? I hear it's a manual change and I don't expect that to be fixed.
Hey guys!
After some tunning PLA printings in my Q2 are looking pretty good, however I'm dealing with some zits in certain curved surfaces, I thought we'll it maybe over extrusion problem, however even reducing PA values I see the same zits around similar surfaces in different prints.
Take a look at my pictures, I tried to investigate how to fix it, and it seems everyone even AI are pointing in the same direction "Turn off the power loss printing restoration" however I don't see that feature in the print settings anywhere.
I have some theories:
A) Power loss feature
B) Over extrusion in that curves
C) Well in fact I only have 2 theories
Print settings: (temp in celsius)
PLA Anycubic Black Basic
Nozzle: 210
Bed: 55
Flow ratio: 96
Max volumetric speed: 14
PA: 0.35
Adaptive PA: Enabled
Adaptive PA for overhangs: Enabled
PA for bridges: 0.2
Seam: aligned
I'll leave the Adaptive PA settings in a further comment.
Hope you can take a look and leave some advice I haven't found a good troubleshooting guide for this (I tried AI but I don't trust 100% percent on it)
I bought a used CC to my colection, will be 3 CC1 when it arrives also I have N4Max, Qidi Q2, Snapmaker U1 and I'm waiting for the new Qidi Max 4 that I just order. Then I will buy the Qidi Plus 4 because it prints beautiful, and I want to try the Flashforge Creator 5.
Why I buy so many printers? Because I like to try different filaments and keeping the same hotend, causes a lot issues, I try use it printer for it type of filament. LOL
(tell me on the comments if I convinced you with this argument)
Hello I recently acquired a Qidi Q2 and I started printing, printed the normal original benchy and the cube that the printer came with and they came out pretty decently. Then I started trying to print a complex model made out of many parts and they've been printing but they keep having these holes that immediately start showing up on the first layer and you can see them on other layers throughout, in the pictures included you can see them.
I'm printing out the models using the generic PLA you can get from Hobby lobby, which the same PLA printed out the qidi cube just fine and I've used the same PLA from Hobby Lobby to print complex figures like ODST soldiers and it worked great on those. Before anyone ask, yes I read what it says on the top panel and the top panel has been slid back or off the entire time.
I'm also using Orca slicer with the Qidi Q2 profile and the generic PLA profile, because I like Orca slicer and dont like how every 3D printer company wants to make their own slicer. I've tried messing with the settings by slowing down the first layer to 30mm/s and that didn't seem to help. I also read a comment somewhere saying to turn down "Slow down for curve" as that was a bug in Orca, I dont know if its still a bug but I figured Id try anyway. I changed the temperatures to the recommended PLA temp and the bed is 60 C and the fan is always on. Im not sure what other settings I might try?
I've read/heard some people say the Qidi q2 bed sucks so I dont know if its poor adhesion to the bed? And I've also read people say the Qidi q2 fan sucks and to upgrade to a Bambu labs fan, so Im unsure if its a cooling issue? I've tried opening the door up as well to see if that would help, but that didn't seem to help either.
I'm also running the latest firmware for the Qidi Q2 at 1.1.1 and I've auto leveled the bed at 60 C and ran through the input shaping and calibration.
Lastly I read at least in another post when I tried searching for information on similar cases, I saw someone say that this is under extruding? I'm not sure if that's what this is? I looked it up and it said that it could be temporary clogs or extruder or gear issues. And it said to also try increasing flow rate or extrusion multiplier? I think when I was reading the qidi wiki in their printing section they said to try increasing the z offset on the first layer, but that didn't seem to help either
Im rather new to 3D printing so Im not sure what it is and how to go about fixing it. I just find it rather strange since the Benchy came out decent and I printed the Qidi Q2 with the same grey generic PLA from HL, and it printed out with no holes or problems. Is it just this build or is it the slicer or is it under extrusion? Id appreciate any help.
Hi every one, I just got my Qidi Max 4 and it is printing like a dream 😀. But I have to use a usb stick to get prints from the slicer to the printer.
Every time that I try to connect using the app it prompts me that it is an invalid version. The printer is updated to the latest version 01.01.06.02.
I don’t have any more tricks to try so that is why I’m trying you guys 😀 🤞
My printer broke during a print and it seems like a common thing, can anyone tell me what I have to buy to fix this ?
Qidi Q2 poop chute/gate will not release and fall during purge and causes filament to clog up nozzle during purge before print starts.
Only had my Q2 for about a week now, so I am fairly new to the unit. Any have similar problems and possibly a solution?
Any explanation would be great here, as I would love to hear how the poop chute/gate works. My gate doesn't seem to open once the purge is done, so it just sits in the closed position and collects right at the top of the poop chute near the nozzle cleaner.
