I missed the duet3 mention (-;

@zapta said in Any one print a Christmas gift this year?: does 3D printing have less 'soul' and the aspect of workmanship than woodworking? They are both ways of creating something that require planning, skill, patience, and creativity. The tools and techniques vary, and perhaps the amount of physical labour, but the end result is the same, and that is to produce an item of some interest or use. Any debate between them really comes down to aesthetics. Perhaps that's where the soul lives, but I think it's only part of it. The other half being in the intention imbued in the item by its creator.

note: the the h parameter is for tmc5160 only not for tmc2224

@mrehorstdmd said in E3D Hermes: This new thing looks great, but it looks like the heat break just screws into the heatsink, the same as the V6. Did they do anything to secure it in the heatsink? I've had the heat break come loose from the V6 hot-end many times during prints, screwing up the print quality. There is no way to securely mount the heatbreak in the heatsink- there's nothing to grab with a wrench on either the heatsink or the heatbreak, and no set screws. You can't twist it in by grabbing the heater block because the throat of the heat break is so thin it will break. This. I have raged so hard about this many times before. It would have been the easiest thing in the world for them to add a set screw in the heatsink that tightens agaínst the upper part of the heatbreak that has no threads on it. This is what i have done in the new extruder that i built, and it works like a charm. But in general the whole e3d design is flawed with the unsupported heatbreak.

@milangupta1 said in Unstable temps all of the sudden. PT100: Any ideas on where I should start ? Check the cartridge for any damage. Check the wiring for any breaks. Move the print head around and see if you can trigger it with movement. Try the other PT100 port on the daughter board.

@phaedrux Fascinating stuff - thanks for sharing.

@bberger Awesome!!

I would prefer a real time thing, probably something that could slow down the step clock if the filament extrusion is getting a bit behind.

@doctrucker said in Finally some insight into pressure inside the hotend.: With regards to retract not relieving all the pressure that would be logical....................... Hi Wes, Yes that's my belief too based on the test work that I've conducted - I think we are in agreement.

In the absence of any specification about what F0 is supposed to mean in a G1 command, I think RRF is behaving entirely reasonably, and Chroma should be fixed.

This will be easier to achieve when implementation of the object model is complete. We're planning on using it to support user-definable fields in DWC, although the details have yet to be designed.

@dc42 said in Secure your printers before it's too late.: (bolding mine): @rcarlyle, your suggestion could certainly be implemented. The question is, would it provide enough additional security to be worthwhile. Let's see what others think. Additional security, such as network segment control via VPN or reverse proxy or similar, will always be needed no matter what security features are added to Duet/RepRap. Several people seem to be saying things that fit with this broad idea... layered security, don't put it directly on the Internet, etc. Therefore, I'd like the see the number of hours devoted to adding security features to Duet/RepRap be relatively small.

I fixed it!! It took a better part of the day to tear it down and build it back up but at least now I can print without being ashamed of the quality. Left is before, right is after. Same gcode. I did a complete realignment of the bearing blocks and bed mounts to make sure they were lined up. I also tightened up the V wheel tensioners on all 4 corners and ensured that the bed raised and lowered smoothly and evenly by hand. Plus I replaced the 40T lead screw and drive pulleys with new ones from OpenBuilds. This time using a 20T drive pulley giving me a 2:1 gear ratio. The belt was also replaced. The cheap toothless flanged idler pulleys on the belt tensioner were replaced with flanged 605 bearings which ran much smoother and didn't rub the belt like the old idler did. I don't know if it was just one or all of those things, but the banding is completely gone. I suspect that the biggest issue was the pulleys. There was visible wobble and movement with the old ones. That's all gone now. It's hard to put a finger on it, but visually the quality of the belt movement just looks better than before. Thanks everyone for the suggestions.

@phaedrux probably there could be also other option to change retraction generated by simplify 3d in g-code tab tick m101 m102 m103 option and in post process put this {REPLACE "M101" "G11"} {REPLACE "M103" "G10"} {STRIP "M102"} I will check this tomorrow at work with that option will be easier to just copy and paste script to another profile

@phaedrux Due to some technical issues at the time of uploading I was unable to use FileZilla and had to work around using a command line tool. Default ftp does not support recursive directory upload, so I looked around and found ncftp. That's why I used it.
