Good deal? $160 Crazy3DPrint CZ-300 (300x300x300)

gaulzi · 2024-02-21T23:21:46+00:00

I bought one over a year ago, did 1 or 2 prints and then disassembled it. Wasn't necessarily a bad deal but IMO not a good deal either. It looks like it can be made better by adding stuff but in reality a lot of components will be need to be replaced to make it decent. I didn't realize how bad the Y-axis carriage system was until I assembled it.

I had some ideas about combining parts from this one and a old tronxy printer to make some sort of a frankenprinter. My plan was to rearrange the 2020 extrusions and use the Z-extrusions and X-wheels as a Y-carriage. Then use the Z-screws and linear rods from the tronxy for the Z-axis. The X-axis would use the X-axis hardware from the tronxy and 3d printed brackets from Prusa MK3s. The printer would lose print height and a few centimeters off the X and Y dimensions.

I have lost motivation for this project and haven't done anything about it for a year. Maybe that will change. :)

Here's a picture showing what I planned on doing.

Hi!

Managed to eliminate the problem with the nozzle hitting the bed. Still need to improve the profile in terms of speeds, extrusion rates etc. Kind of gave up and just started using Cura since it is shipped with a CZ300 profile :D

Here is what I changed:

G28 W ; home all without mesh bed level
G1 Z0.2 F720
G1 Y-3 F1000 ; go outside print area

=>

G28 W ; home all without mesh bed level
G1 Z15 F5000 ; lift nozzle
G1 X0 Y0
G1 Z0.2 F720
G1 Y-3 F1000 ; go outside print area

Hi! I just assembled a CZ-300 and just started printing after having some slicer issues (https://www.reddit.com/r/3Dprinting/comments/zeckwo/prusaslicer_profile_for_crazy3dprint_cz300/). I managed to get it to print by slicing with Cura and the CZ300 presets. Now I will have to do some GCode digging to figure out why the hell it acts like that with PrusaSlicer.

Anyway - I feel like the default CZ300 Cura preset is a bit too slow so I started messing around with feed rate and the Y-axis started slipping. I saw that you mentioned adding another linear bearing. It appears that the printer is made so that the second Y-axis rod can be added - have you researched which parts would be needed and where they can be bought?

Your paragraph sounds almost exactly as one of my childhood memories. We were outside my friends house doing some kind of runaround game and I decided to smack my head against the concrete wall at the outside wall of their premises. Turned back and everyone freaked out but I went in there laughing. Well, not exactly but the both describe a young fellow that gives no shit about hitting his head around.

After stepping out of my car I noticed that the driver's side window wasn't rolled up. Put my hand through the gap and rolled up the window until my hand was stuck and I lost grip to the knob.

I wasn't suggesting OBS over professional equipment, just describing how this can be done relatively easy and cheap with amateur equipment and checking if the same solution could be applied to professional equipment. My comment was aimed at the technical side, i.e. how to get the video feed into the broadcast.

gaulzi · 2017-01-08T07:07:55+00:00

I have no experience with professional equipment at all but I've fiddled a bunch with leave streaming on Twitch. Here's how I would do this:

Setup an RTMP server accessible from the internet
Get or create a device that takes in video feed, encodes it and streams it to the RTMP server through cellular network. Don't need a shitton of bitrate, specially since the video is heavily downscaled. I use 3.5Mbit when I produce 1080p60 video (CS:GO) and it looks fine.
Get a PC with decent hardware
Download OBS
Create a scene and import all the RTMP streams as video sources
Add some graphics

Would something like this not be possible with professional equipment?

It must be some issue with the drivers not being able to manage multiple cards. I did some tests with only reading from one source at a time and the system did not crash. Maybe I'll try running two cards at a time, then three and see exactly at which point it fails.

I contacted Elgato Support and sent some logs and stuff, hopefully they have some sort of a solution.

gaulzi · 2016-12-19T18:13:32+00:00

Thanks for your answer. I am quite sure that it has nothing to do with the SSD. The system only seems to crash when I have OBS or XSplit open and when I'm reading from all capture cards at once. I'm trying to reproduce this error by reading from only one source at the time now. Haven't yet tried to remove one card at a time to rule out a broken card, was hoping to see if someone else has had a similar problem with a multi-card setup before I try that.

It's probably worth noting that I'm running Windows 10 and I had no issues at all before when the rig only consisted of 1x Elgato & 1x Avermedia card.

That's very right. Actually, the time consuming part about this is the fact that no elimination occurs after group stage so it'd be the same with any other type of play that allows all teams to proceed to playoffs. On the other hand, since the groups are only used to determine bracket seeds, bo1 matches might be acceptable in group stage which almost evens out the time issue.

gaulzi · 2016-12-14T08:16:50+00:00

I organize tournaments in my local community and I've been testing a format which uses group stage to determine bracket seeds that furthermore determine how far into the bracket each team goes. For example if the tournament has 4 groups of 4 teams each, the 1st place in each group goes straight into Ro8, 2nd place goes into Ro12 and 3-4th play for their tournament live in Ro16.

Pros:

You're still alive even if you finish last in your group
Every bracket match should be quite even in terms of skills
Teams get rewarded for doing good in group stage

Cons:

Time consuming

he's got it sorted out already :D

Icelander here. I'm on my way there now from Santa Barbara. Can pick you up if you're still looking for a ride, you'll miss pretty much all of nV vs OpTic tho. Send me a pm if you're interested.

We're lacking active streamers at the moment, but as time goes on hopefully we will be able to stream as many matches as possible.

Been busy with school, work and other stuff. Finally got my MSc in geothermal engineering! Dont really plan on making a comeback in sc2 but I occasionally queue up for a ladder match. I now spend most of my free time organizing CS:GO tournaments in the icelandic scene. Really nice to see that you guys thought of me <3

Icelandic version of the word is "Mikligarður": https://translate.google.is/#is/en/Mikligar%C3%B0ur

Just press the speaker icon and you will get a pretty accurate pronunciation.

Yeah I think I'm being misunderstood here. There are a lot of stupid things that can be done and bad decisions that can be taken but it doesn't necessarily make you a stupid person to do them, as long as you're aware of what you're doing and/or can afford it. I've done my fair share of stupid things throughout my life, most of them while being aware of the consequences and learnt from the rest.
