DivideByZero

Amazing, thank you so much for testing this out. Also for explaining the deep blue line bit so I can check myself. Thanks again!!

I know it lets you set it higher... but did it actually do over 100, that's the question? Thanks for the warning about wearing out your filament, but I was aware already. Just need to test some things. Cheers

Hi, Looking at upping my "maximum retraction count" to help test my stringing issues. Default was 90, max is 99 before Cura gets angry and goes orange. What happens when I exceed this? Does it ignore numbers over 100, or does it do it anyway and just warn me in Orange that I am doing something crazy? Is Maximum Value Warning, warning you that you have gone past the maximum value - or does it just warn once you exceed it? "retraction_count_max": { "label": "Maximum Retraction Count", "description": "This setting limits the number of retractions occurring within the minimum extrusion distance window. Further retractions within this window will be ignored. This avoids retracting repeatedly on the same piece of filament, as that can flatten the filament and cause grinding issues.", "default_value": 90, "minimum_value": "0", "maximum_value_warning": "100", "type": "int", "enabled": "retraction_enable", "settable_per_mesh": false, "settable_per_extruder": true }, Thanks /0

Downloaded a profile from Facebook last night. Imported that and it doesn't have the issue... A previously downloaded profile I had from a week or so ago does have the issue. Do the devs look in this forum? Someone must know what this is about. Notihng in the manual, but it must be coming from somewhere.

I'm on 3.6 too and I already reinstalled. Will try on a different pc I guess.

Well, damn. What is wrong with my Cura? Just did it again, with Extra fine 0.06 and changed it to 0.1 and created a new profile. Global = 0.1 Extruder1 = 0.06. Seeing how I have some weird stuff going on, I would very much like to get to the bottom of this.

Hi, I have used the change at Z option to create temperature towers, which is a really handy feature. Is there a way to add other options to the change on Z selection? What I was looking to build is a retraction tower (as I am lazy and this would be super handy when you change filaments. The two options I would like to use would be "Retraction Distance" and "Retraction Speed". It would be so nice to do one print for retraction distance, going from 0mm to 7mm in one print. Then a second to change from 5mm/s up to like 70 or something. Currently, it takes me at least 16 prints to do this, it's slow, it takes extra material and is generally a pain. If there is a way to add settings to the change on Z, please let me know. if not, and anyone else knows another way to achieve this, please do let me know (and register my interest to add this as a feature)! Thanks

Nope - not the startup gcode. Removed my start code, restarted Cura, even tried a few profiles - the settings still didn't line up. Took the "Normal" profile, which is 0.15 LH. Changed LH to 0.2 and created a new profile from the current settings. Global = 0.2 (correct) Extruder 1 = 0.15 (wrong) So, where is this extruder 1 setting coming from? The profile I created, while based on the Normal template, had been changed before creation. Does this happen to you too?

I actually Had a thought about this while I was trying to sleep last night. I do have a custom start-up script which does a wipe. That's the only place I can think it's coming from. I'm out and about at the moment, but will check and confirm when I get home.

Attached you can see the Global Vs Extruder settings. I have also shown the actual profile setting and also what I can see under the Extruder setting... I must be missing something somewhere as I don't see Extruder layer Height of 0.15 set anywhere. Thanks

Hi, I'm still not clear on where Global Settings come from and why they are different (or where you set them). The reason I am curious about this in relationship to my stringing is I have tried all the usual stuff (and more) so I am wondering what is going on in the slicer now. This global settings is really what I want to understand for this question - I am not looking for stringing help in itself. But, here is what I have tried for stringing (probably not in order): 1) Temp tower to get the ideal temp for my PLA. 2) Retraction tests 3) Retraction speed tests 4) Calibrated e-steps 5) Calibrated extrusion multiplier 6) Jerk settings 7) Travel Settings 8 ) print speed settings 9) Acceleration settings 10) Tried 2 different firmwares 11) Changed Bowden tube three times - stock, Capricorn XS, Normal PTFE 12) Changed Bowden Couplers 13) Changed part cooling fan ducts 3 times 14) Disassembled and checked my extruder - recalibrated esteps 15) Tried different brand of PLA, repeating most of the steps above 16) Checked bed levelling, in case this was creep from lower levels being too squished. 17) Changed nozzle Maybe some other stuff. Really want to understand the global settings bit next. Thanks /0

Hi, When looking at a saved profile, it shows 2 tabs. Global Settings and Extruder 1 (as I have a single extruder CR10S). But the settings for the profile are different. For example: Global Settings Layer Height = 0.2 Extruder 1 Layer Height = 0.15 So, how come there are two different settings stored in the one profile and yet I can only find one place to set these. I have been having some major issues with stringing (to the point of destroying prints) so I am wondering if the settings are different to what I think I am using somehow. Any ideas how this works? Thanks

Yep, sorted. Cura crashed out on me the other day and I think some stuff ended up a bit odd. New profile is not doing it. Thanks

Yeah, when I updated the FW I saved it. Something had changed the max_x_jerk etc. from 12 to 20 (just double checked). Reboot and it was back to normal. Thanks - good info. Definitely happening in Cura. I even have M204 + M205 setup in my startup code for the correct values... but then after that, I get this: ;LAYER_COUNT:50 ;LAYER:0 M107 M204 S5000 M205 X30 Y30 G0 F3600 X130.766 Y130.38 Z0.2 M204 S500 M205 X20 Y20 ;TYPE:SKIRT Above we can see X20 Y20 - which is what it ends up. Just to double check... I don't have "Enable Acceleration Control" or "Enable Jerk Control" on, that's all I need to switch off right? Let me reset my profile again and see if I still get that. At least I can find out without having to print now. Thanks

Hi, In Cura 3.6 I switched off Jerk control via the tick box. I would have assumed that this should then let the printer use its defaults. Though something strange happened, after printing, I did an M503 and it returned a jerk of 20. I double checked my FW and it was set to 8 when I flashed it. I rebooted my printer and a M503 then reported the 8 I was expecting. Any suggestions what I should do to test what is causing this please? Any ideeas what I can look for in the GCODE to check if something is changing it? Ultimately, what I want is to be able to control the print speed itself in Cura, but accelleration and jerk should be done by the printer firmware defaults. FYI. Printer is a CR-10S running Marlin 1.1.8. Thanks
