I sliced a flow tower from Thingiverse and added M221 commands in the appropriate places in the gcode but when the gcode file is opened the change in flow is not shown. Some flow change is evident in the infill but not the major changes of 5% every 40 layers. Is it normal for this not to show up or have I done something wrong in the gcode?

Sorry it took so long to respond. I had no idea Cura needs to know that for collision avoidance. The hotend cooler I'm installing says the hotend will have a Y offset of -9mm, how does that fit in with this?

I'm a bit confused about the function of printhead offset settings. Since I changed control boards on my Ender 3 Pro I have an issue I'm trying to resolve where ABL and printing is offset from where it should be on about 25mm on the X and 35mm on the Y axis. While I was doing research on Marlin settings I saw in an article that this could be caused by the settings in firmware not matching the settings in the slicer. What is the function of the settings in Cura and how do the two correlate with each other? Should the "Apply offsets to Gcode" be checked?

I've installed a printed cooling setup, HeroMe 6, and the doc says the Y offset is -9mm. Does this have to be changed in Cura print head settings? If so what setting, I'm a bit confused about the function of the X & Y min and X & Y max settings. The current settings are the default for an Ender3 Pro: Xmin -26, Ymin -32, Xmax 32, Ymax 34

I've only had my Ender 3 Pro for a bit less then a year and I think I'm getting the hang of it. I'm really happy with how my prints turn out but one thing has become my nemesis, supports. They either fuse to the model and are almost or totally impossible to remove, generally with interfaces, or the overhang quality is as bad if not worse than printing without them, generally without interface. The last models I printed needed support everywhere and even without interfaces on one it fused to the bottom enough to tear a hole in the top of the structure it sat on, the other it completely fused to the bottom and a wall and I destroyed the print and still couldn't get it separated. The rest were difficult to remove I even had to cut part of it out with a Dremel to get it off. Attached is .3mf of that print. Any suggestions? 5015-cooling ducts.3mf

This is the first print I've done using Cura 5 and I don't know if it's related but I've never had it happen before. Most of the print was excellent the quality improvement is definetly noticeable but when it got to the taller part on right right I didn't actually witness it but it looks like it kept pushing the nozzle into the print at each layer. Printed @ .16 layer height with adaptive layers turned on and it appears to have happened at the last layer thickness change. Sorry about the photo quality. Crappy phone, crappy lighting and shiny black filament are a bad combo.

GregValiant, I did a test print following your instructions and it worked perfectly. You also helped me out with paussing and changing colors a while back. I'm also realizing that G-code isn't that difficult except for remembering what each command does what.

Thanks, a couple of ways to try it. Something new to try to master.

Sorry if this is obvious but I'm still learning about this stuff. I want to print a base with raised lettering and a logo on the top in a different color. I need to print the lettering at a high resolution but printing the base takes forever if I do the whole thing like that. Is it possible to split a model in Cura, save each as a separate STL then print the second one on the first with different settings? I've tried splitting it and It looks like it would work but I don't want to trash my printer to find out that it doesn't. Thanks

🤣🤣 Well it seems to have printed fine but I wasn't able to hover over it to see if the weird stuff actually printed or not.

Project attached. It's a Thingiverse STL so I don't have the original model. I found a few other anomalies, extra interior walls that aren't attached to each other. I've tried running it through MeshLab following a tutorial and while it found and fixed several problems it still shows up the same in Cura. Strange thing is I tried slicing it with PursaSlicer and none of those show up and there's no message of it not being watertight. Fan_Mount_Bottom_v2.3mf

I've noticed these odd square structures in a few models. They pop up randomly usually in or near corners and are only in one or two layers then disappear. I don't think they affect the printing quality but I'm just curious.

Yeah the firmware upgrade was just a flash in the pan along with all the other cool stuff I "have to have" like motherboard, glass bed, dual Z conversion, all metal hot end .......... Every so often I have to slap myself and get back to reality. I did easily get the pause to work by putting it in with Cura then editing the gcode by substituting in the G4 command for M0. That lets Cura handle all the stuff needed to properly get everything back what it needs to be to resume properly. Then do your manual retract and feed. Works like a charm. Also added a couple of annoying beeps. 😁

I swore I wouldn't do any major mods to this thing until I had it tweaked and learned more about the whole process but now this has me thinking of different firmware. The only mods aside from some printed stuff like filament guides the only thing I've replaced is the bed springs and the plastic extruder. After reading the problems people had I replaced them before I even turned it on for the first time. As far as your rant 🙂 I worked in engineering for several years dealing with both our Chinese plant and vendors. Great, intelligent, polite people and I loved working with them but sometimes they would make changes that had us shaking our heads in wonder.

Thanks GregValiant, I ran the gcode and the printer auto homed twice, paused for 30 sec., beeped annoyingly and said all done. So you were right obviously M0 doesn't work. I'll try your technique on some test prints.
